A shoe store developed the following estimated regression equation relating sales to inventory investment and advertising expenditures.

$$\hat { y } = 25 + 10 x _ { 1 } + 8 x _ { 2 }$$

where

$$\begin{aligned} x _ { 1 } & = \text { inventory investment } ( \$ 1000 \mathrm { s } ) \\ x _ { 2 } & = \text { advertising expenditures } ( \$ 1000 \mathrm { s } ) \\ y & = \text { sales } ( \$ 1000 \mathrm { s } ) | \end{aligned}$$

Estimate sales resulting from a $15,000 investment in inventory and an advertising budget of$10,000.

Tell whether each sequence is arithmetic, geometric, or neither. Find the next three terms of the sequence.

$$1,1,2,3,5 , \dots$$

Graph the solution set of each inequality or compound inequality. $2 x+y \leq 1$ and $x \geq 2 y$

Suppose that a ball is rolling down a ramp. The distance traveled by the ball is given by the function in each exercise, where t is the time, in seconds, after the ball is released, and s(t) is measured in feet. For each given function, find the ball's average velocity from

$$t _ { 1 } = 3 \text { to } t _ { 2 } = 3.01.$$

$$s ( t ) = 12 t ^ { 2 }$$

Consider a random variable $X \sim \operatorname{Po}(m).$ a. Find m given that P(X = 1) + P(X = 2) = P(X = 3). b. If m =2.7, find i. $\mathbf{P}(X \geqslant 3)$ ii. $\mathbf{P}(X \leqslant 4 | X \geqslant 2)$

Look back at the story. Which hints point to the surprise ending?

Use the information that follows. A recent poll of residents in a certain community revealed the following information about voting preferences:

$$\begin{array}{l|l|l|l|l} & \text{Democrat} & \text{Republican} & \text{Independent} \\ \hline\text{Male} & 50 & 40 & 30\\ \hline \text{Female} & 60 & 30 & 25\\ \hline \end{array}$$

Events M, F, D, R, and I are defined as follows: M: Resident is male, F: Resident is female, D: Resident is a Democrat. R: Resident is a Republican. I: Resident is an Independent. Find each conditional probability and state in words the meaning of

$$P(D|M)$$
