Regression analysis was applied between sales data (in $1,000s) and advertising data (in $100s) and the following information wa

Darya [45]

Answer:

A. $66,000

Step-by-step explanation:

The relationship between sales data (in $1,000s) and advertising data (in $100s) is:

$y=12+1.8x$

If if advertising is $3,000, then x =$30, and the point estimate for sales (in thousands of dollars) is:

$y(30)=12+1.8*30\\y=66$

Converting it to dollars, the point estimate for sales is:

$S=1,000*66\\S=\$66,000$

Izzie recently took a math test where each correct answer was worth 8.7 points. She also correctly answered a bonus question wor

harina [27]

Let's use x as the number of questions she answered correctly. If we make an equation of out the question, it would be 8.7x+13=108.7 To solve the equation subtract 13 from both sides. So it will leave you with 8.7x=108.7-13, which is 8.7x=95.7. Divide both sides by 8.7, which will give you x=11. She answered 11 questions correctly.

Please tell me how to find the Slope of lines, (or do one for me) [I’ll try to help you back]

zheka24 [161]

The slope of a line often referred to as the ( $\frac{rise}{run}$ ) is the rate of change in a line. It can be found using the following formula.

$\frac{y_2-y_1}{x_2-x_1}$

Where ( $x_1,y_1$ ) and ( $x_2,y_2$ ) are points on the line. For each problem, substitute the points on the line into the formula and solve for the slope.
