Suppose 150 randomly selected adults that live in Arlington Heights were asked if they own a tablet. Of the 150 surveyed, 69 reported owning a tablet. A. Construct and interpret a 90% confidence interval to estimate the proportion of all adults living in Arlington Heights that own a tablet.
B. Using your answer from part a, do we have convincing evidence that less than half of the adults who live in Arlington Heights own a tablet? Explain.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

hi there!

step-by-step explanation:

a roof pitch is basically for every inch rise there is 12 inches run.

the height of the roof is also known as the rafter.

formula: rafter^2 = rise^2 + run^2

rafter^2 = 5^2 + 12^2

rafter^2 = 25 + 144

rafter ^2 = 169"^2

the height of the roof from the lowest point to the highest point is 169"^2.
