Exhibit 15-2A regression model between sales (y in $1000s), unit price (x1 in dollars) and television advertisement (x2 in dolla
Semmy [17]

Answer:

Sales are expected to increase positively.

Step-by-step explanation:

The model is y =7-3*X1+5*X2

Here, y is the depended variable and X1 and X2 are independent variable.  

Holding the unit price constant X2 (television advertisement) is increase by $1 dollar

SSR= 3500

SSE=1500

So, TSS = SSR+SSE = (3500+1500) = 5000

Now r^2= 1 - (SSR/TSS) = 1 - (3,500/5,000) = 1 - 0.70 = 0.30

So, the sample correlation coefficient (r) = (0.3)^(1/2) = 0.547

We can conclude that sample correlation indicates a strong positive relationship.

What is the length of the side of a right triangle that has a side length of 12in and a hypotenuse that measures 15ft
Viktor [21]

Answer: 14.96ft


Step-by-step explanation:

  1. To solve this exercise you must apply the Pythagorean Theorem, which is:

a=\sqrt{b^{2}+c^{2}}

Where a is the hypotenuse, and b and c are the other sides of the triangle.

2. You have that the sides given measures 12 inches. 1 feet has 12 inches. Therefore, this side measures 1 feet.

2. Then, when you  solve for one of the sides and substitute the values given in the problem into the formula shown above, you obtain that the length of  the side of the rigth triangle is:

 b=\sqrt{(15ft)^{2}-(1ft)^{2}}

b=4\sqrt{14}=14.96ft
