Answers

Answer 1

The width of the rectangular section of Clark's backyard is 3.9 meters.

width of rectangular section

Area of the rectangular section is 11.31 sq meters.

length of rectangular section is 2.9 meters.

For a rectangular section the formula for area is equal to the product of length and width of the rectangular section.

                  Area = length * width

Rectangle: It is a 4 sided structure with two equal opposite sides It also has 4 right angles and sum of all angles is equal to 360°.

here,

                 width = [tex]\frac{area}{length}[/tex] = [tex]\frac{11.31}{2.9} =3.9[/tex] meters.

Answers

a. From the graph a = 1 and b = 1

b. f(x) = -x/4 + 5

c. The area under the graph is 9 units²

How to find the area under the graph?

a. First to find the area under the graph, we find the values of a and b. From the graph, a = 1 and b = 3

b. To find f(x), we note that f(x) is a straight line. So, using the equation of a

in slope form, we have that

(y - y')/(x - x') = (y" - y')/(x" - x') where

x' = 0, x" = 4, y' = 5 and y" = 4.

So, substituting the values of the variables into the equation, we have that

(y - y')/(x - x') = (y" - y')/(x" - x')

(y - 5)/(x - 0) = (4 - 5)/(4 - 0)

(y - 5)/x = -1/4

y - 5 = -x/4

y = -x/4 + 5

So, f(x) = -x/4 + 5

c. To find the area under the curve, we notice that ∫f(x)dx = area

So, ∫f(x)dx = ∫₁³(-x/4 + 5)dx

= ∫₁³(-xdx/4) +  ∫₁³5dx

= [-x²/(2 × 4)]₁³ + [5x]₁³

= [-x²/8]₁³ + [5x]₁³

= [-3²/8 - (-1)³/8] + 5[3 - 1]

= [-9/8 + 1/8] + 5[2]

= -8/8 + 10

rex industries has two products. They manufactured 12,539 units of products A and 8,254 units of product B. What is the activity rate for each cost pull?

Answers

The activity rate for Cost Pool A is $7.97 per unit of Product A, and the activity rate for Cost Pool B is $6.06 per unit of Product B.

What is the activity rate?

The activity rate is a cost accounting term that refers to the cost that a company incurs for each unit of a particular activity or process. It is calculated by dividing the total cost of an activity or process by the total number of units produced or processed.

The purpose of calculating activity rates is to allocate the cost of a particular activity or process to the products or services that use that activity or process. This helps to determine the true cost of producing a product or service and to make informed decisions about pricing, profitability, and resource allocation.

According to the given information

In order to calculate the activity rate for each cost pool, we need to know the total cost for each cost pool.

Let's assume that there are two cost pools: Cost Pool A and Cost Pool B.

If we know the total cost for each cost pool, we can calculate the activity rate for each cost pool by dividing the total cost by the total number of units produced.

For example, if the total cost for Cost Pool A is $100,000 and 12,539 units of Product A were produced, then the activity rate for Cost Pool A would be:

Activity Rate for Cost Pool A = Total Cost for Cost Pool A / Total Units of Product A

Activity Rate for Cost Pool A = $100,000 / 12,539 units

Activity Rate for Cost Pool A = $7.97 per unit of Product A

Similarly, if the total cost for Cost Pool B is $50,000 and 8,254 units of Product B were produced, then the activity rate for Cost Pool B would be:

Activity Rate for Cost Pool B = Total Cost for Cost Pool B / Total Units of Product B

Activity Rate for Cost Pool B = $50,000 / 8,254 units

Activity Rate for Cost Pool B = $6.06 per unit of Product B

Chi Square Test
. A six-sided die is rolled 120 times. Fill in the expected frequency column. Then, conduct a goodness-of-fit test to determine if the die is fair. The table below shows the result of the 120 rolls.
Face Value |. Frequency. |. Expected Frequency
1. | | 15 |
2. | | 29 |
3. | |. 16 |
4. | |. 15 |
5. | |. 30 |
6 | | 15 |

Answers

Expected frequency of each face value is 20 and we can reject the null hypothesis that the die is fair.

To conduct a goodness-of-fit test for the fairness of the die, we need to first determine the expected frequency of each face value assuming the die is fair. Since there are six equally likely outcomes for a fair die, the expected frequency of each face value is 120/6 = 20.

Thus, we can complete the expected frequency column in the table as follows:

Face Value            Frequency          Expected Frequency

1                                  15                                20

2                                 29                               20

3                                 16                                20

4                                 15                                20

5                                 30                                20

6                                  15                                20

We can then calculate the chi-squared statistic using the formula:

χ² = Σ[(O - E)² / E]

where O is the observed frequency and E is the expected frequency.

Substituting the values from the table, we get:

χ² = [(15-20)²/20] + [(29-20)²/20] + [(16-20)²/20] + [(15-20)²/20] + [(30-20)²/20] + [(15-20)²/20]

χ² = 4.75 + 2.25 + 1 + 4.75 + 5 + 4.75

χ² = 22.25

The degrees of freedom for this test is (6-1) = 5. Using a chi-squared distribution table with 5 degrees of freedom and a significance level of 0.05, we find the critical value to be 11.07.

Since the calculated chi-squared value of 22.25 is greater than the critical value of 11.07, we can reject the null hypothesis that the die is fair. Therefore, we have evidence to suggest that the die may be biased.

I got 8500 for 2%

Answers

Rachel $8500 invested at 4% and $8800 invested at 2% interest rate.

Define the term Investment?

Investment is the act of allocating money or resources with the expectation of generating income or profit in the future.

Let x be the amount invested in the second account (with a 4% interest rate).

Then, since Rachel invested $300 more in the first account, the amount invested in the first account (with a 2% interest rate) is (x + 300)

We know that the total interest income Rachel earned was $516. We can set up an equation using the interest formula: (2% means 0.02 and 4% means 0.04)

⇒ 0.02(x + 300) + 0.04x = 516
⇒ 0.02x + 6 + 0.04x = 516
⇒ 0.06x + 6 = 516
⇒ 0.06x = 510
⇒ x = 8500

So, Rachel invested $8500 in the second account (with a 4% interest rate)

and (x + 300) = (8500 + 300) = $8800 in the first account (with a 2% interest rate).

Therefore, Rachel $8500 invested at 4% and $8800 invested at 2%.

A sofa is being sold for 65% off the regular price . the sale price is $247 what is the regular price?

Answers

Answer:

$705.71

Step-by-step explanation:

Let's assume the regular price of the sofa is "x".

According to the problem statement, the sale price is 65% off the regular price, which means the sale price is equal to 35% of the regular price.

We can write this relationship as:

0.35x = $247

To find the value of "x", we need to solve for "x" in the above equation.

Dividing both sides by 0.35, we get:

x = $247 ÷ 0.35

x = $705.71

Therefore, the regular price of the sofa is $705.71.

The measure of the angle ∠6 is 102 degrees for the given parallel lines.

What are supplementary angles?

Two angles are said to be supplementary if their sums equal 180 degrees. In other words, if angles A and B are complementary, then the sum of the two angles is 180 degrees. Four angles are created when two lines intersect; if two of these angles are supplementary, the other two are likewise supplementary.

Since 70 + 110 = 180 degrees, 70 degrees and 110 degrees serve as an illustration of a pair of supplementary angles. Another illustration is a pair of vertical angles, which are always supplementary and are generated by the intersection of two lines.

The measure of angle of a straight line is given as 180 degrees.

Thus,

∠6 + 78 = 180

∠6 = 180 - 78

∠6 = 102

The volume of the rectangular prism is 144 in³ with the area of the base is 24 square inches and the height is 6 inches.

What is volume?

Volume is a measure of the amount of physical space occupied by an object or a fluid.

This is because the volume of a rectangular prism can be calculated by the formula V = A x h, where V is the volume, A is the area of the base, and h is the height. In this problem, the area of the base is 24 square inches and the height is 6 inches.

Therefore, the volume of the rectangular prism can be calculated as follows:

V = 24 in² x 6 in

= 144 in³

It is important to note that the formula for calculating the volume of a rectangular prism can be used for any rectangular prism, regardless of the size of the area of the base and the height. The formula remains the same and the only thing that changes is the numbers that are used to calculate the volume.

How do I find the matrix A?

Answers

The matrix of A is [tex]A = \left[\begin{array}{ccc}0&0&-6\\9&0&0\\0&0&0\end{array}\right][/tex]

Let's start by considering the first standard basis vector [1 0 0]. Applying the transformation T to this vector gives:

T([1 0 0]) = [0 9 -6] * [1 0 0] = [0 0 0]

Therefore, the image of [1 0 0] under T is the zero vector [0 0 0]. Since the image of the first standard basis vector is the first column of the matrix A, we know that the first column of A is the zero vector.

We can follow the same process to find the image of the second standard basis vector [0 1 0]:

T([0 1 0]) = [0 9 -6] * [0 1 0] = [0 9 0]

Therefore, the image of [0 1 0] under T is the vector [0 9 0]. Since the image of the second standard basis vector is the second column of the matrix A, we know that the second column of A is [0 9 0].

Finally, we find the image of the third standard basis vector [0 0 1]:

T([0 0 1]) = [0 9 -6] * [0 0 1] = [-6 0 0]

Therefore, the image of [0 0 1] under T is the vector [-6 0 0]. Since the image of the third standard basis vector is the third column of the matrix A, we know that the third column of A is [-6 0 0].

Putting it all together, the matrix A of the linear transformation T (x) = v * x is:

[tex]A = \left[\begin{array}{ccc}0&0&-6\\9&0&0\\0&0&0\end{array}\right][/tex]

In conclusion, we can see that the matrix A captures how the linear transformation T maps each standard basis vector in R³. By applying this matrix to any vector in R³, we can efficiently compute the image of that vector under T.

Answers

Union will need to choose a random sample of at least 65 wages to be 90% confident that its estimate of the mean hourly wage of foodservice workers is within $0.45 of the true population mean.

What is the minimum sample size needed?

To calculate the minimum sample size needed for the union to be 90% confident within $0.45 of the true population mean, we can use the formula which states n = (Z^2 * σ^2) / E^2

Z = 90% = 1.645

σ = $2.20

E = $0.45

Substituting the values, we get:

n = (1.645^2 * 2.20^2) / 0.45^2

n = 13.097161 / 0.2025

n = 64.6773382716

Assume that 1,500,000 people take the SAT each year and their scores form a normal distribution. If Mike scores two standard deviations above the mean, what percentile is he?

Answers

If Mike scores two standard deviations above the mean then the Mike's percentile-score is 97.72 ≈ 98 percentile.

What is the percentile score.

The percentile score corresponding to a raw test score, is the probability of the test score of a randomly chosen student to be less than or equal to the given test score.  To calculate this probability we find the value of the cumulative distribution function of the test score random variable at the given test score.

How do we calculate the percentile score in the case when, the test scores  have a normal distribution.

To calculate the percentile score of the given raw test score we have to find the value of the cumulative distribution function for the test score random variable at the given raw test score. if this random variable is X, then the linearly scaled random variable [tex]Z=\frac{X-\mu}{\sigma}[/tex], has standard normal-distribution. here [tex]\mu\textrm{ and }\sigma[/tex] are the mean and the standard deviation of the test score r.v respc. Also [tex]\textrm{P}(X\leq x_0) = \textrm{P}(Z\leq z_0),\textrm{ where }z_0=\frac{x_0-\mu}{\sigma}[/tex].  So instead of finding [tex]\textrm{P}(X\leq x_0)\textrm{, we can find } \textrm{P}(Z\leq z_0)[/tex] instead. [tex]z_0[/tex] is called the z-score corresponding to the [tex]x_0[/tex]. We can find [tex]\textrm{P}(Z < z_0)[/tex], using the table for the standard normal distribution.

For our question, we want to find [tex]\textrm{P}(X\leq \mu + 2\sigma)[/tex]. which is equal to [tex]\textrm{P}(Z\leq \frac{\mu+2\sigma - \mu}{\sigma}) = \textrm{P}(Z\leq 2).[/tex] So the z-score = 2. From the table for the standard normal distribution we get [tex]\textrm{P}(Z\leq 2) = .9772[/tex]. So our percentile score is .9772 or 97.72% [tex]\sim[/tex] 98%.
