The fitted regression is Sales = 832 − 28.2 Price. (a-1) If Price = 1, what is the prediction for Sales? (Round your answer to 1

almond37 [142]

Answer:

Part (a-1): The prediction for Sales is 803.8.

Part (a-2): The correct option is: An increase in price decreases sales.

Part (B): The prediction for sales is 211.66

Part (C): The intercept is meaningful as sales will be maximized when price is zero.

Step-by-step explanation:

Consider the provided regression:

Sales = 832 − 28.2 Price

(a-1) If Price = 1, what is the prediction for Sales?

Substitute Price = 1 in above regression.

Sales = 832 − 28.2 (1) = 803.8

Hence, the prediction for Sales is 803.8.

Sales (a-2) Choose the correct statement.

Here we can observe that as we increase the price, sales decrease.

Thus, the correct option is: An increase in price decreases sales.

(b) If Price = 22, what is the prediction for Sales?

Substitute Price = 22 in above regression.

Sales = 832 − 28.2 (22)

Sales = 832 − 620.4

Sales = 211.66

Hence, the prediction for sales is 211.66

Sales (c) Choose the right option.

As we increase the price, sales decrease that means the sales will be maximum if the price is 0.

The intercept is meaningful as sales will be maximized when price is zero.

What is the circumference of circle P?<br><br> Express your answer in terms of π.

Zolol [24]

Answer:

Circumference of a circle= $2\pi r$

Step-by-step explanation:

The circumference of any circle is the total length of its boundary which can be calculated by the formula:

Circumference of a circle= $2\pi r$

Where 'r' is the radius of the circle

For, the given circle the circumference can be find in terms of $\pi$ by putting some value of radius in the formula, which gives the circumference in terms of $\pi$ .

I have way more questions than this answer them if you want pleaseee!!

aliina [53]

The right answer is Option C.

Step-by-step explanation:

Given inequality is

6(2x-1) > 24

Solving the inequality

$6*2x-1*6>24\\12x-6>24$

Adding 6 on both sides

$12x-6+6>24+6\\12x>30$

Dividing both sides by 12

$\frac{12x}{12}>\frac{30}{12}\\x>\frac{5}{2}$

Therefore,

$x>\frac{5}{2}$

The right answer is Option C.
