Answer 2

Answer:

Equation for Angle 3- 90-38=52

Angle 3= 52

Angle 5= 38

Angle 6= 52

Step-by-step explanation:

Angle is 90 degrees.

Angle 2 is 38 degrees.

If you are just looking at the bottom half(Angle 6, Angle 1, and Angle 2) They are all supposed to add up to equal 180 degrees because it is a supplementary angle.

So you add 90 and 38 and it gives you 52(Angle 6).
90+38+52=180

Then a complementary angle is two angles that equal 90 degrees.

So if you take Angle 2(38 degrees) and subtract it from 90, you get 52. Which is Angle 3.

You do the same with Angle 6 and Angle 5.

Angle 6(52 degrees) subtract from 90 and you get 38.

Then you add 38 and 52 and you get 90.

Then 180-90=90, so Angle 4 is 90 degrees.

If the dimensions of a prism with surface area 42 m^2 and volume 18 m^3 are enlarged by a factor of 4, what is the surface area and volume of the prism?

Answers

Let the original dimensions of the prism be x, y, and z. Then, its surface area and volume are given by:

Surface area = 2xy + 2xz + 2yz = 42
Volume = xyz = 18

We can use these equations to solve for the individual dimensions. First, we can solve for z in terms of x and y from the surface area equation:

2xy + 2xz + 2yz = 42
2z(x + y) = 42 - 2xy
z(x + y) = 21 - xy

Next, we can substitute this expression for z into the volume equation and solve for x and y:

xyz = 18
xy(21 - xy) = 18
21xy - xy^2 = 18
xy^2 - 21xy + 18 = 0
(xy - 2)(xy - 9) = 0

So, either xy = 2 or xy = 9. Since the dimensions of a prism must be positive, we can only use the solution xy = 9. Solving for x and y gives:

xy = 9
x + y + z = 21/xy = 7/3
x = 3, y = 3, z = 1/3

Now, we can scale up the dimensions by a factor of 4 to get the new dimensions of the enlarged prism:

x' = 4x = 12
y' = 4y = 12
z' = 4z = 4/3

The surface area and volume of the enlarged prism are then given by:

Surface area = 2x'y' + 2x'z' + 2y'z' = 576
Volume = x'y'z' = 64

Therefore, the surface area of the enlarged prism is 576 m^2 and the volume is 64 m^3.

SA = 2lw + 2lh + 2wh = 42 m^2 ... (1)

And the volume of the original prism is given by:

V = lwh = 18 m^3 ... (2)

If you enlarge the dimensions of the prism by a factor of 4, then the new dimensions will be 4l, 4w, and 4h. The new surface area of the prism will be:

New SA = 2(4l)(4w) + 2(4l)(4h) + 2(4w)(4h)

= 32lw + 32lh + 32wh

= 32(2lw + 2lh + 2wh)

= 32(42)

= 1344 m^2

So, the surface area of the enlarged prism is 1344 m^2.

Similarly, the new volume of the prism will be:

New V = (4l)(4w)(4h)

= 64lwh

= 64(18)

= 1152 m^3

So, the volume of the enlarged prism is 1152 m^3.

Therefore, the surface area of the prism is 1344 m^2 and the volume of the prism is 1152 m^3 after the dimensions are enlarged by a factor of 4.

Answers

A company claims that its tablet computers have an average recharge time of 3 hours with a standard deviation of 1.4 hours. Using a random sample of 50 company tablet computers, a consumer group determines a mean recharge time of 2.5 hours. H0: µ = 3 Ha: µ < 3 a = 5% σ = 1.4 z* = –1.65.

Based on the given information, we can perform a one-sample z-test to determine if the sample mean of 2.5 hours is significantly different from the claimed population mean of 3 hours, with a significance level of 0.05.

The null hypothesis H0 is that the population mean recharge time µ is equal to 3 hours, and the alternative hypothesis Ha is that µ is less than 3 hours.

We will find the test statistic z using the formula

z = (x - µ) / (σ / √n)

Where x is the sample mean of 2.5 hours, µ is the population mean of 3 hours, σ is the population standard deviation of 1.4 hours, and n is the sample size of 50.

z = (2.5 - 3) / (1.4 / √50) = -2.38

The calculated test statistic z of -2.38 is less than the critical value z* of -1.65 at a significance level of 0.05, indicating that we can reject the null hypothesis H0.

Hence, we can conclude that the mean recharge time of the company tablet computers is less than 3 hours, based on the sample of 50 tablets tested by the consumer group.

The standard error measures the variability of the sample mean from the true population mean. It represents the standard deviation of the sampling distribution of the mean and gives an estimate of how much the sample means will vary from one sample to another.

b. When calculating the standard error of the mean, we assume that the sample was randomly selected from the population, and that the sample size is large enough (usually, n > 30) for the central limit theorem to apply.

c. To reduce the standard error of their estimate of the mean home range size, researchers could increase the sample size, which will decrease the standard error by reducing the variability of the sampling distribution of the mean.

Alternatively, they could improve the precision of their measurements or reduce measurement errors to decrease the standard deviation of the sample, which will also decrease the standard error.

Mixed numbers with unlike denominators ______ be subtracted from each other.

A. Mixed numbers with unlike denominators cannot be subtracted from each other.

B. Mixed numbers with unlike denominators can be subtracted from each other.

Answers

Answer:

B. Mixed numbers with unlike denominators can be subtracted from each other.

Step-by-step explanation:

Mixed numbers are numbers that have a whole part and a fractional part, such as 2 1/4 or 3 3/5. Unlike denominators are fractions that have different numbers in the bottom, such as 1/4 and 3/5. They are also called unlikeable denominators because they make math harder and more annoying. Who likes to deal with fractions anyway?

Mixed numbers with unlike denominators can be subtracted from each other, but only if you follow some tedious steps. First, you have to find a common denominator for the fractions, which is the smallest number that both denominators can divide into. This is like finding a common enemy for two rival gangs. For example, to subtract 2 1/4 from 3 3/5, we need to find a common denominator for 1/4 and 3/5. The least common denominator is 20, because both 4 and 5 can divide into it. Then, we have to multiply both fractions by the same factor to get equivalent fractions with the same denominator. This is like dressing up both gangs in the same uniform to make them look alike. For example, we multiply 1/4 by 5/5 and 3/5 by 4/4 to get:

2 1/4 = 2 5/20

3 3/5 = 3 12/20

Now we can subtract the fractions by subtracting the numerators and keeping the denominators the same. This is like taking away some members from each gang and seeing who has more left. For example, we subtract 5/20 from 12/20 and get 7/20. Then we subtract 2 from 3 and get 1. Finally, we add the whole part and the fractional part together to get the final answer. This is like adding up the remaining members of one gang and giving them a name. For example, we get:

3 12/20 - 2 5/20 = (3 - 2) + (12/20 - 5/20) = 1 + 7/20 = 1 7/20

Therefore, the correct answer is B. Mixed numbers with unlike denominators can be subtracted from each other. But why would you want to do that? It's much easier to use decimals or percentages instead. Fractions are so last century.

The Normal model is a good first-choice to model data if the data is normally distributed or approximately normally distributed

Normally distributed or approximately Normally distributed. The Normal distribution, also known as the Gaussian distribution, is a continuous probability distribution that is widely used in statistical modeling due to its mathematical properties and practical applications in many fields.

When the data is Normally distributed, the Normal model provides a good approximation of the underlying distribution of the data. This means that the parameters of the Normal distribution can be estimated from the data using methods such as maximum likelihood estimation, and the resulting model can be used to make predictions and conduct statistical inference.

However, it is important to note that the Normal model may not be appropriate for all types of data, particularly if the data exhibits significant departures from Normality. In such cases, other distributional models or non-parametric methods may be more appropriate.

(B) For A = P(1.0052), the principal amount of money is increasing at a 52% interest rate.
(C) For A = P(0.86)t, the principal amount of money is decreasing at a 14% interest rate.
(D) For A = P(0.68)t, the principal amount of money is decreasing at a 68% interest rate.

Answers

The correct statement regarding the annual interest rate for the given equations is (A) For A = P(1.025), the principal amount of money is increasing at a 2.5% interest rate.

What is an equation?

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides separated by an equals sign (=).

In the equation A = P(1 + r)t, the annual interest rate is represented by the variable "r". It is not correct to directly interpret the value of (1 + r) as the interest rate, as it represents the factor by which the principal amount is multiplied over time to yield the total amount.

Let's analyze each given equation to see which statement correctly relates information regarding the annual interest rate:

(A) For A = P(1.025), the equation does not have a term for time (t), so it cannot represent the growth of a principal amount over time. It simply represents the total amount (A) as 102.5% of the principal amount (P), which means that the interest rate is 2.5% per year.

(B) For A = P(1.0052), similar to the previous equation, this equation does not have a term for time (t), so it cannot represent the growth of a principal amount over time. It simply represents the total amount (A) as 100.52% of the principal amount (P), which means that the interest rate is 0.52% per year.

(C) For A = P(0.86)t, the value of (0.86) represents the factor by which the principal amount is multiplied over time to yield the total amount. Since (0.86) is less than 1, it means that the principal amount is decreasing over time, not increasing. The interest rate in this case is -14% per year (negative because the principal amount is decreasing).

(D) For A = P(0.68)t, similar to the previous equation, the value of (0.68) represents the factor by which the principal amount is multiplied over time to yield the total amount. Since (0.68) is less than 1, it means that the principal amount is decreasing over time, not increasing. The interest rate in this case is -32% per year (negative because the principal amount is decreasing).

Therefore, the correct statement regarding the annual interest rate for the given equations is:

(A) For A = P(1.025), the principal amount of money is increasing at a 2.5% interest rate.

1. discuss the internal validity of the regressions that you used to answer empirical exercise 8.2(l). include a discussion of possible omitted variable bias, misspecification of the functional form of the regression, errors in variables, sample selection, simultaneous causality, and inconsistency of the ols standard errors.

Answers

Answer: Empirical Exercise 8.2(l) involves running a regression to estimate the relationship between two variables of interest. In evaluating the internal validity of the regression used to answer this exercise, we need to consider several potential sources of bias and other issues that could affect the accuracy of the estimated relationship.

Omitted variable bias: This occurs when a relevant variable is left out of the regression model. If this happens, the estimated coefficients may be biased and inconsistent. For example, if we are estimating the effect of education on earnings but fail to include information about work experience, the coefficient on education may be biased upwards.

Misspecification of the functional form of the regression: If the relationship between the dependent variable and the independent variable(s) is nonlinear, we may need to use a different functional form of the regression equation to obtain accurate estimates. If we fail to do so, the estimated coefficients may be biased and inconsistent.

Errors in variables: When measurement errors occur in the independent variable(s), this can cause the estimated coefficients to be biased and inconsistent.

Sample selection: If the sample used to estimate the regression equation is not representative of the population of interest, then the estimated coefficients may be biased and inconsistent.

Simultaneous causality: When there is a two-way causal relationship between the dependent variable and the independent variable(s), it may not be possible to determine the direction of causality from the regression coefficients.

Inconsistency of the OLS standard errors: If there is heteroskedasticity or autocorrelation in the data, then the ordinary least squares (OLS) standard errors may be inconsistent. This can lead to incorrect conclusions about the statistical significance of the estimated coefficients.

To address these issues, researchers should take care to select an appropriate sample, use a suitable functional form of the regression equation, and account for any relevant variables that could be omitted or measured with errors. It may also be necessary to use alternative statistical techniques to account for simultaneous causality or heteroskedasticity in the data. Finally, researchers should always test the robustness of their results to different model specifications and sensitivity to potential sources of bias.

The probability that Amber's bus arrives on time is 5/6.
If her bus is on time then the probability she arrives at work by 9 am is 4/5.
If her bus is late then the probability she arrives at work by 9 am is 3/10.

Work out the probability that Amber does not arrive at work by 9 am.
Give your answer as a fraction in it's simplest form.

Answers

Let A be the event that Amber's bus arrives on time, and let B be the event that Amber arrives at work by 9 am. Then we want to find P(not B), the probability that Amber does not arrive at work by 9 am.

We can use the law of total probability to calculate P(not B) as follows:

P(not B) = P(not B | A) * P(A) + P(not B | not A) * P(not A)

where P(A) = 5/6 is the probability that Amber's bus arrives on time, and P(not A) = 1/6 is the probability that her bus is late.

If her bus is on time, then the probability she arrives at work by 9 am is 4/5. So, P(not B | A) = 1 - 4/5 = 1/5.

If her bus is late, then the probability she arrives at work by 9 am is 3/10. So, P(not B | not A) = 1 - 3/10 = 7/10.

Putting it all together, we get:

P(not B) = (1/5) * (5/6) + (7/10) * (1/6) = 1/6

Therefore, the probability that Amber does not arrive at work by 9 am is 1/6.
Final answer:

The probability that Amber does not arrive at work by 9 am is calculated by summing the probabilities of two scenarios: the bus being on time and Amber not arriving by 9 am and the bus being late and Amber not arriving by 9 am. The calculated probability for her late arrival at work is 17/60.

Explanation:

The subject of this problem is probability. There are two scenarios in which Amber may not arrive at work by 9 am: either the bus is on time but she does not arrive by 9 am or the bus is late and she does not arrive by 9 am.

First, let's consider the probability that Amber's bus arrives on time, which is said to be 5/6. If her bus is on time, the probability that she arrives at work by 9 am is 4/5, which means that the probability she does not arrive by 9 am is 1-4/5 = 1/5. Therefore, the probability that the bus is on time and she does not arrive by 9 am is 5/6 * 1/5 = 1/6.

Alternatively, consider the scenario where the bus is late. We can find the probability of this by subtracting the probability that the bus is on time (5/6) from 1, so the probability that the bus is late is 1/6. If her bus is late, the probability she arrives at work by 9 am is 3/10, implying that the probability she does not arrive by 9 am is 1-3/10 = 7/10. Hence, the probability that the bus is late and she does not arrive at work by 9 am equals 1/6 *7/10 = 7/60.

Thus, the total probability that Amber does not arrive at work by 9 am is 1/6 + 7/60 = 10/60 + 7/60 = 17/60.

The wrights took out an 8000 dollar personal loan for some home improvement projects. They can pay off the loan in 2 years with monthly payments of $354.56, or in 5 years with monthly payments of $154.66.

Answers

The first option with 2-year term and higher monthly payments is better since it results in less total paid in the end.

What is personal loan?

An individual borrower can receive a personal loan to utilise for personal, family, or household needs. The majority of personal loans are unsecured, which means they are not secured by property like a house or a car. Instead, the approval of a personal loan is determined by the borrower's creditworthiness and capacity to pay back the loan. The lender decides the loan amount, interest rate, and repayment conditions for a personal loan based on the borrower's credit score, income, and employment history, among other things. Personal loans are frequently used to pay for unforeseen bills, finance home improvements, and consolidate debt.

For the given plans of payment of 2 years and 5 years we have:

Option 1: 24 monthly payments of $354.56 = $8,534.56 total paid.

Option 2: 60 monthly payments of $154.66 = $9,279.60 total paid.

Comparing the total payment for the various years we have see that the plan with 2 years payment is better option.

Hence, the first option with 2-year term and higher monthly payments is better since it results in less total paid in the end.

You get a bag of 30 components. And you know that, with probability 0. 1, there is one faulty component in the bag, and with probability 0. 9, all the components are in good working. You are not sure you have a faulty component in the bag, so you propose to test k of the components. (a) How many ways are there of selecting k out of the 30 components? (b) Assume the bag has a faulty component. How many ways are there of selecting k out of the 30 components that include the faulty component? (c) Use your answers from parts (a) and (b) to determine a formula for the probability of including a faulty in the k selected ones, if there was a faulty component in the bag. (d) Evaluate your answer from part (c) for k = 5. (e) Assume now that you did select a batch of 5 components, measured each of them and found that none were faulty. What is the probability that there is a faulty component left in the bag? Remember that there were two original possibilities for the bag: all the components could be good, or one component could be faulty

Answers

The probability of having at least one faulty component in your selection is 0.41 or 41%.

The probability of having at least one faulty component in a selection of 5 can be found by calculating the probability of having no faulty components and then subtracting this from 1.

The probability of having no faulty components in a selection of 5 is:

P(no faulty) = (0.9)^5 = 0.59

Therefore, the probability of having at least one faulty component in a selection of 5 is:

P(at least one faulty) = 1 - P(no faulty) = 1 - 0.59 = 0.41

So the probability of having at least one faulty component in your selection is 0.41 or 41%.
