Wants to build a regulation-size pool table that is 9 feet in length.The plans he ordered are 18 by 36 inches.what is the scale

Vlad [161]

Length = the longer side

He wants to build a table with a length of 9ft.

The plans he has are 18ft x 36ft
Length of the plans = 36ft
Compare the length of the plans to the length he wants:
36 ft vs 9 ftThe length in the plans is 4 times longer than the length he wants.

Length he wants / Length of plans = your dilation scale factor

9 / 36 = ¼
1/4 = dilation scale factor
Hope this answers your question, and May the Force Be With You!

In a survey of 1,532 former UF students, 84% said they were still in love with Tim Tebow. The survey's sampling error was 2%. Us

nalin [4]

Answer:

confidence interval for the proportion of all former UF students who are still in love with Tim Tebow.

(0.79 , 0.89)

Step-by-step explanation:

step 1:-

Given sample survey former UF students n = 1532

84% said they were still in love with Tim Tebow

p = 0.84

The survey sampling error

$= \sqrt{\frac{p(1-p)}{n} }$

Given standard error of proportion = 2% =0.02

Step 2:-

The 99% of z- interval is 2.57

The 99% of confidence intervals are

p ± zₐ S.E (since sampling error of proportion = $\sqrt{\frac{pq}{n} }$

$(0.84 - 2.57X0.02 , 0.84 + 2.57X0.02)$

on simplification , we get

(0.84 - 0.0514 , 0.84 + 0.0514)

(0.79 , 0.89)

conclusion:-

confidence interval for the proportion of all former UF students who are still in love with Tim Tebow.

(0.79 , 0.89)
