The answer is B) 3/4
this is because if you add up the amount of water from the first column (1/4) you get two full cups. if you add up the amount of water from the third column (3/4) you get 3.75 cups
1 yard equals 36 inches. So 36 x 6 yards=216 inches... But you still have the half of the yard so you would divide 36 by 2 and get 18... So then you add the extra 18 inches to the 216 inches to get 234in altogether.... Hope this helped! Good luck!

➷ 40 inches = 3.33333
Area = length x width
Substitute the values:
Area = 9 x 3.33333
Solve:
Area = 30ft^2

Answer:
The approximate 90% confidence interval is;
70,244 to 70,732
Step-by-step explanation:
Here, we want to calculate the approximate 90% C.I for the situation
Mathematically;
CI = mean ± (z * SD)/√n
From the question;
mean = 70,438
SD = 645.3
n = 30
we can get z from the CI table
90% CI is same as; 1.645 z-score
So , substituting these values;
CI = 70,438 ± ( 1.645 * 645.3)/√30
CI = 70,438 ± 194
So the CI = 70,438 -194 to 70,438 + 194
= 70,244 to 70,732
