Answer:

The correct option is (D).

Step-by-step explanation:

The Complete question is:

The 95% confidence interval bound for the slope coefficient for Fantasy Tech is (1.32, 2.01) and for the intercept is (-0.02, 0.02). Which of the following statements are consistent with the data for Fantasy Tech? Check all that apply. The probability that the true beta is equal to zero is virtually nonexistent. There is a 95% probability that the true beta is between –0.02 and 0.02. The estimate for the beta for Fantasy Tech is precise. There is a 95% probability that the true beta is between 1.32 and 2.01.

Solution:

The 95% confidence interval bound for the slope coefficient for Fantasy Tech is (1.32, 2.01).

The (1 - α)% confidence interval for population parameter implies that there is a (1 - α) probability that the true value of the parameter is included in the interval.

Or, the (1 - α)% confidence interval for the parameter implies that there is (1 - α)% confidence or certainty that the true parameter value is contained in the interval.

This implies that there is 95% or 0.95 probability that the true value of β, for the Fantasy Tech. lies between 1.32 and 2.01.

Thus, the correct option is (D).

A house number is displayed on a plaque in the shape of a regular 7-sided polygon. The area of the plaque is 70 squared inches.
Svetllana [295]

Answer:

The perimeter of the plaque is 28 inches.

Step-by-step explanation:

Given : A house number is displayed on a plaque in the shape of a regular 7-sided polygon. The area of the plaque is 70 squared inches. The perpendicular distance from a side to the center is 5 inches to the nearest inch.

To find : What is the perimeter of the plaque?

Solution :

The 7-sided polygon can be divided into seven triangles whose height, h is equal to the perpendicular distance from each side to the center.

The base of each triangle is equal to the length of a side, s.

The area of each triangle is A=\frac{1}{2}\times s\times h

The area of the whole polygon is A_p=\frac{1}{2}\times 7s\times h

Now, the perimeter of a regular 7-sided polygon is P=7s.

Substitute in area,

A_p=\frac{1}{2}\times P\times h

We have given, A_p=70\ in^2 and h=5\ in

70=\frac{1}{2}\times P\times 5

P=\frac{70\times 2}{5}

P=28

The perimeter of the plaque is 28 inches.

Answer:

2 and 5 for sure. I think 4 is correct, but your teacher may not.

Step-by-step explanation:

The given expression reduces down to -7m - 8 = m - 4

1 cannot give -15m on the right. One seldom sees that mistake on Brainly.

3 does not do that. - 3m is not - 7m

4 has it's sides reversed. I would count it is right, others may not. I'm trying to say the left side is on the right side and the right side is on the left. That to me is OK.

5 is Ok as well the left is written as -8 - 7m which is -7m - 8. and with -4 and m

6 has been reduced on the left incorrectly. the right is it's signs backwards

2 4(?) and 5
