-6, -2, 2, 6, ...

Answers

Answer 1

The 50th partial sum of the given arithmetic sequence is 4600

Calculating partial sum of an arithmetic sequence

From the question, we are to calculate the 50th partial sum of the given arithmetic sequence

The given arithmetic sequence is

-6, -2, 2, 6, ...

To find the 50th partial sum of the sequence, we will find the sum of the first 50 terms in the sequence.

The sum of n terms of a sequence is given by the formula,

S = n/2(a + l)

Where a is the first term

and l is the last term

l is given by

l = a + (n - 1)d

Where d is the common difference

In the given series

a = -6

d = -6 -(-2) = -6 + 2 = 4

Thus,

l = -6 + (50 - 1)4

l = -6 + 49×4

l = -6 + 196

l = 190

Then,

S = 50/2(-6 + 190)

S = 25(184)

S = 4600

Hence,

The sum is 4600

using cramer rao lower bound method, with a random sample of size n, find a minimum variance unbiased estimator of the parameter,λ of a poisson population

Answers

The minimum variance unbiased estimator of the parameter,λ of a poisson population is λ = Σxi/n.

What is variance?

Variance is a measure of how spread out a set of data is. In statistics, it is the average of the squared differences from the mean of a set of values. It is calculated by taking the sum of the squared deviations from the mean and dividing it by the number of data points.

According to given information:

Let X1, X2, ..., Xn be a random sample from a Poisson distribution with mean λ. The likelihood function is given by:

[tex]L(\lambda | x) = \pi[e^{(-\lambda)} \lambda^{(xi)} / xi!][/tex]

Taking the natural logarithm and differentiating with respect to λ:

ln L(λ | x) = -nλ + ln(λ) Σxi - Σln(xi!)

d/dλ ln L(λ | x) = -n + Σxi/λ

Setting the derivative equal to zero and solving for λ, we get:

λ = Σxi/n

This is the sample mean of the Poisson distribution, which is an unbiased estimator of λ. Moreover, using the Cramer-Rao lower bound, we can show that it is also the minimum variance unbiased estimator of λ.

Answers

The expression for the area of the compound shape in cm² is 2x^2 + 11x - 6.

What is the expression for the area?

To find the expression for the area of the compound shape, we need to first calculate the individual areas of Shape A and Shape B, and then add them together.

The area of Shape A is given by multiplying its length and width:

Area of Shape A = (x + 3) * (x + 2)

The area of Shape B is given by multiplying its length and width:

Area of Shape B = (x + 6) * (x - 2)

Now, we can add the two areas together to get the expression for the area of the compound shape:

Area of compound shape = Area of Shape A + Area of Shape B

= (x + 3) * (x + 2) + (x + 6) * (x - 2)

Expanding the above expression, we get:

= x^2 + 2x + 3x + 6 + x^2 + 6x - 12

Minimise : 3x+2y
Subject to: 5x+y=10

Find this question?

Answers

This is a linear programming problem with three constraints and two variables, where the objective is to minimize the expression 3x + 2y subject to the following constraints:

5x + y = 10

x + y = 6

x + 4y = 12

The first constraint represents a straight line in the x-y plane, the second constraint represents another straight line, and the third constraint represents yet another straight line. The feasible region is the region where all three constraints are satisfied simultaneously, which is the intersection of the three lines.

To solve this problem, you can use the method of substitution or elimination to solve for one variable in terms of the other in two of the equations, and then substitute this expression into the third equation to obtain a single equation in one variable. You can then solve for that variable, and use back-substitution to find the values of the other variable.

For example, using the first and second equations, you can solve for x in terms of y as follows:

x = 6 - y (from the second equation)

y = 10 - 5x (from the first equation)

Substituting y = 10 - 5x into the third equation, you get:

x + 4(10 - 5x) = 12

Simplifying this equation, you get:

-19x + 40 = 0

Solving for x, you get:

x = 40/19

Using x = 40/19 and the equation x + y = 6, you can solve for y as:

y = 6 - x = 6 - 40/19 = 94/19

Therefore, the minimum value of 3x + 2y subject to the given constraints is:

3(40/19) + 2(94/19) = 222/19

And the values of x and y that minimize this expression are:

x = 40/19 and y = 94/19.

Rebecca is x years old.Mary is 8 years older than rebecca. Jill is three times older than mary. The sum of their ages is 67.
A) form an expression in terms of x

Answers

Answer:

A) 5x+32=67

Rebecca is 7, Mary is 15, and Jill is 45

Step-by-step explanation:

Rebecca is x years old.

If Mary is 8 years older than Rebecca, Mary's age is 8 more than x.

We can write Mary's age as:

x+8

Jill is three times older than Mary.

This means that Jill's age is equal to three times x+8.

We can write Jill's age as:

3(x+8)

Use the distributive property.

3(x+8)=

3x+24

So, Jill's age (in terms of x) is 3x+24.

The sum of their ages is 67, so if we add all of their ages, we will get 67.

x+(x+8)+(3x+24)=67=

5x+32=67

Not sure if you want this solved, but here it is:

5x+32=67=

5x=35=

x=7

Let's find Mary's age.

x+8=

7+8=

15.

Now, let's find Jill's age.

3x+24=

3(7)+24=

21+24=

45.

So, Rebecca is 7, Mary is 15, and Jill is 45.

4. The correct answer is a. Forgoing the interest that the owners could have earned on their savings if they had not invested their savings in the business. Opportunity cost refers to the cost of forgoing the next best alternative when making a decision. In this case, the opportunity cost of investing savings in a business is the interest that could have been earned if the savings were invested elsewhere.

5. The correct answer is b. Macroeconomics looks at the economy as a whole while microeconomics looks at single units in the economy. Macroeconomics is concerned with the overall performance of the economy, including issues such as inflation, unemployment, and economic growth. Microeconomics, on the other hand, focuses on individual units within the economy, such as households, firms, and markets.

Edward and Diana walked to the dock at 2 miles per hour, jumped into the boat, and motored to Dillion at 10 miles per hour. If the total distance was 12 miles and the trip took 5 hours in all, how far did they go by boat?

Answers

The distance for boat is,

=  43.2 miles

Given that;

Edward and Diana walked to the dock at 2 miles per hour, jumped into the boat, and motored to Dillion at 10 miles per hour

Now, For Walk DATA:

Rate = 2 mph ; time = x hrs.

Then, distance = 2x miles

For Boat DATA:

Rate = 10 mph ; time = 5 - x hrs

Then, distance = 10 (5 - x) miles

Hence, We can formulate;

distance + distance = 12 miles

2x + 10 (5 - x) = 20

2x + 50 - 10x = 20

30 = 8x

x = 3.6

Hence, Boat time ,

5 - x = 5 - 3.6 = 1.4 hr (boat time)

And, The value of Boat distance = 12x = 12 x 3.6 = 43.2 miles

Americans and found that 69.6% of the sample agreed with the statement "the future of the nation is a
significant source of stress for me."
Using a 99% confidence level, determine the margin of error, E, and a confidence interval for the true
proportion of all Americans that say the "the future of the nation is a significant source of stress for me."
Report the confidence interval using interval notation. Round solutions to four decimal places, if necessary.




The margin of error is given by E:

A 99% confidence interval is given by:

Answers

To find the margin of error, we can use the formula: E = z√((p(1-p))/n)

How is margin of error determined?

where z is the z-score for a 99% confidence level, p is the sample proportion, and n is the sample size.

From the table of standard normal distribution, the z-score for a 99% confidence level is 2.576.

Plugging in the values, we get:

E = 2.576√((0.696(1-0.696))/664) ≈ 0.0385

So the margin of error is 0.0385.

To find the confidence interval, we can use the formula:

p ± E

where p is the sample proportion and E is the margin of error.

Plugging in the values, we get:

0.696 ± 0.0385

So the 99% confidence interval for the true proportion of all Americans that say "the future of the nation is a significant source of stress for me" is (0.6575, 0.7345). In interval notation, this can be written as [0.6575, 0.7345].

4.5 meters = 0.45 decimeters
4.5 meters = 45 decameters

Answers

The statement that shows equivalent measurements is "4.5 meters = 0.0045 kilometers".

How to solve the problem?

To convert meters to kilometers, we need to divide by 1000, since there are 1000 meters in a kilometer. Therefore, 4.5 meters is equal to 4.5/1000 = 0.0045 kilometers.

The other statements are incorrect:

4.5 meters is not equal to 0.045 centimeters, since there are 100 centimeters in a meter, so 4.5 meters is equal to 450 centimeters.

4.5 meters is not equal to 0.45 decimeters, since there are 10 decimeters in a meter, so 4.5 meters is equal to 45 decimeters.

4.5 meters is not equal to 45 decameters, since there are 10 meters in a decameter, so 4.5 meters is equal to 0.45 decameters.

It is important to be able to convert between different units of measurement in order to make accurate comparisons and calculations. In this case, the correct conversion factor was used to convert meters to kilometers, resulting in an equivalent measurement.

In circle O, chords AB and CD intersect at E, AE = 3 inches, BE = 8 inches, and CE is 2 inches longer than DE. What is the length of DE, expressed in inches?

Answers

Okay, let's break this down step-by-step:

* Circle O has chords AB and CD that intersect at E

* AE = 3 inches

* BE = 8 inches

* CE is 2 inches longer than DE

So we know:

AE = 3 inches

BE = 8 inches

CE = DE + 2 inches

To find DE, we can use the Pythagorean theorem for any right triangle:

a^2 + b^2 = c^2

In this case:

3^2 + 8^2 = c^2

9 + 64 = 73

c = 8 inches

So the hypotenuse AE forms a right triangle with leg BE of length 8 inches.

Now we have the length of one leg (BE = 8 inches) and the hypotenuse (AE = 8 inches).

We can use the relation between leg, hypotenuse and sine to calculate the other leg (DE):

sin(A) = DE / 8

DE = 8 * sin(A)

Without knowing the angle A, we can make an estimate:

sin(A) ≈ A (for small A)

So DE ≈ 8A inches

Now we know:

CE = DE + 2 inches

And DE ≈ 8A inches

So: 8A + 2 = DE

=> DE = 10A

And since A is small, we can say: DE ≈ 10 * A inches

To summary, if AE = 3 inches and BE = 8 inches,

then DE ≈ 10 * A inches

DE is approximately 10 times some small angle A.

The other angle that is congruent to  ∠DFA is: ∠BFC

How to identify Congruent angles?

Congruent angles are defined as two or more angles that are said to be identical to each other. This means that the measure of these angles is equal to each other. These type of angles do not make any difference in the congruence of angles, which tells us that they can be acute, obtuse, exterior, or interior angles.

Now, we want to find the angle that is congruent to ∠DFA.

By inspection, we can see that ∠BFC is an opposite angle to ∠DFA.

We know that Opposite angles are the two angles opposite each other when two lines cross. They can also be called vertical angles due to sharing a vertex, which is the point where the two lines connect. Opposite angles always have the same measurement, making them congruent.

Thus, ∠BFC is congruent to  ∠DFA.

The end behavior of f(x) is described as follows:

As x -> -∞, f(x) -> ∞.As x -> ∞, f(x) -> 0.

How to obtain the end behavior of a function?

The end behavior of a function is given by the limit of the function is the input x goes to either negative infinity or positive infinity.

The function for this problem is given as follows:

f(x) = 4(5/7)^x.

It is an exponential function with base with absolute value less than 1, hence the end behavior is given as follows:

Increases to the left of the graph -> As x -> -∞, f(x) -> ∞.Approaches the horizontal asymptote y = 0 at the right of the graph -> As x -> ∞, f(x) -> 0.

The mean weight of an adult is 70 kilograms with a standard deviation of 8 kilograms.

If 87 adults are randomly selected, what is the probability that the sample mean would be greater than 70.8 kilograms? Round your answer to four decimal places.

Answers

The probability that the sample mean would be greater than 70.8 kilograms is given as follows:

0.1762 = 17.62%.

How to obtain probabilities using the normal distribution?

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score represents how many standard deviations the measure X is above or below the mean of the distribution of the data-set, depending if the obtained z-score is positive(above the mean) or negative(below the mean).The z-score table is used to obtain the p-value of the z-score, and it represents the percentile of the measure X in the distribution.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation given by the equation presented as follows: [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

The parameters for this problem are given as follows:

[tex]\mu = 70, \sigma = 8, n = 87, s = \frac{8}{\sqrt{87}} = 0.8577[/tex]

The probability is one subtracted by the p-value of Z when X = 70.8, hence:

Z = (70.8 - 70)/0.8577

Z = 0.93

Z = 0.93 has a p-value of 0.8238

1 - 0.8238 = 0.1762.
