Divide the length of the scale drawing by the scale (2.5) then multiply that by the scale feet (3)
11 inches / 2.5 = 4.4
4.4 x 3 = 13.2 feet
Answer: 13.2 feet
<span>(4 - 8i)(2 - 7i)
Use the method FOIL
8 - 28i - 16i + 56i^2
Subtract 16i from -28i
Final Answer: 8 - 44i + 56i^2</span>
So you would have to cut the two minutes into one minute. so 5 / 2 is 2.5. so they go through 2.5 pages per minute. so then multiply 2.5 by 106 = 265

Answer:
a) The 90% confidence interval is 
b) The margin of error is 0.063.
Step-by-step explanation:
We have to construct a 90% confidence interval for the proportion of students enrolled in college or a trade school within 12 months of graduating from high school in 2013.
We have a sample of 160 students, and a proportion of:

The standard deviation is:

As the sample size is big enough, we use the z-value as statistic. For a 90% CI, the z-value is z=1.645.
Then, the margin of error is:

Then, the 90% confidence interval is:
