Answer:

B. 73

Step-by-step explanation:

Complementary angles equal 90 degrees, while supplementary angles equal 180 degrees. Therefore, if one angle in a pair of complementary angles equals 17, you would use the equation 90-17 to find the measure of the other angle.

bixtya [17]

Answer:

They can either decrease the confidence level or increase the sample size, that is, survey more students.

Step-by-step explanation:

The width of a confidence interval is given by:

M = z*\frac{\sigma}{\sqrt{n}}

In which z is the critical value correponding to the confidence level(higher confidence level, higher z is), \sigma is the standard deviation of the population and n is the size of the sample.

The students realize that this interval contains a large margin of error. What can they do to make a narrower interval?

Looking at the formula for M, they can either decrease the confidence level or increase the sample size, that is, survey more students.

Help? pls?? I've got the first part, just need a lil help
OlgaM077 [116]

Find the time it will take:

195 miles / 50 miles per hour = 3.9 hours.

1 hour = 60 minutes:

0.9 hours x 60 = 54 minutes.

3.9 hours = 3 hours and 54 minutes.

Add 3 hours and 54 minutes to the time it leaves:

3:30 pm + 3 hours = 6:30 PM

6:30 + 54 minutes = 7:24 PM
