Answer:
the answer is 18 feet because that line in the middle of the triangle is half the size of AC
B:Because it says the lev of it
The correct answer is the first choice, ($1818.30, $5077.70.)
To find this, we first find the z-score based on the confidence level:
Convert 95% to a decimal: 95%=95/100 = 0.95
Subtract from 1: 1-0.95 = 0.05
Divide by 2: 0.05/2 = 0.025
Subtract from 1: 1-0.025 = 0.975
Using a z-table (http://www.z-table.com) we see that this value is associated with a z-score of 1.96.
Next, we identify

Next we find

Next we find

Next, we multiply this value by z:
1.96(831.479) = 1629.70
The confidence interval is given by
Answer:
87%
Step-by-step explanation:
If you divide 2 by 15 you get 13.3 repeating.
So that's the percent that's <u>not</u> there.
Then after that just do the percentage leftover
