Board Game Sales

A small company is selling a new board game, and they need to know how many to produce in the future.

After 12 months, they sold 4 thousand games; after 18 months, they sold 7 thousand games; and after 36 months, they sold 15 thousand games.

This information could be reasonably estimated using a single linear model?
Group of answer choices

True

False

If so, use the model to estimate the number of games sold after 48 months. If not, explain your reasoning.

Answers

Answer:

true

Step-by-step explanation:

False

The amount of games sold is not linear. If it were linear, the amount of games sold at 36 months would be 12 thousand games, assuming we are going off of the information given at 12 months

Answers

Answer: 39°, 72°, 45°, 150°

Step-by-step explanation:

A circle has 360 degrees. [tex]\frac{1}{360}[/tex] would be equal to 1°

1) [tex]\frac{39}{360}[/tex] would be equal to 39° based on the rule above ^^

2) This fraction has a denominator of 5. Turn the denominator into 360. We can do this by multiplying the bottom by 72, since 360 ÷ 5 = 72 (make sure to multiply the numerator by 72 as well!)

[tex]\frac{1*72}{5*72}[/tex] = [tex]\frac{72}{360}[/tex]

This is equal to 72°

3) Use the same method as before

[tex]\frac{1*45}{8*45}[/tex] = [tex]\frac{45}{360}[/tex]

This is equal to 45°

4) Use the same method as before

[tex]\frac{5*30}{12*30}[/tex] = [tex]\frac{150}{360}[/tex]

This is equal to 150°

[tex]SA_2 = 2(lw + lh + wh) = 2(20 * 4 + 20 * 6 + 4 * 6) = 2(80 + 120 + 24) = 2 * 224 = 448[/tex]
