The class sizes of elementary school classes in a public school district are normally distributed with an unknown population mea
weqwewe [10]

Answer: (17.14,\ 22.86)

Step-by-step explanation:

The confidence interval estimate for the population mean is given by :-

\overline{x}\pm ME, where \overline{x} is the sample mean and ME  is the margin of error.

Given : Sample mean: \overline{x}=20

The margin of error for a 98% confidence interval estimate for the population mean using the Student's t-distribution : ME=2.86

Now, the confidence interval estimate for the population mean will be :-

20\pm2.86=(20-2.86,\ 20+2.86)=(17.14,\ 22.86)

Hence, the 98% confidence interval estimate for the population mean using the Student's t-distribution =  (17.14,\ 22.86)

If the Alexanders completed the 735 mile trip in 15 hours, what was their average rate of travel?
Darina [25.2K]
The rate of travel here is in mph - "miles per hour".

That just means how many miles you can travel in one hour. In this problem, you're given 15 hours, and the distance they travel within those 15 hours.

Therefore, you should divide both the number of miles and the number of hours by 15 to find out how far they can travel in 1 hour.

735 ÷ 15 = 49 miles
15 ÷ 15 = 1 hour

Their average rate of travel was 49 miles in 1 hour, which is 49 mph.

What is the slope of y = 1 + 5?
IgorLugansk [536]

Step-by-step explanation:

if there is no typo, then that is

y = 1 + 5 = 6

y = 6

has no term in x.

that means 6 is the constant result of the line function, no matter what x value we pick.

and that means this is a horizontal line (parallel to the x-axis) going through the point y=6 or (0, 6).

remember that the slope is the ratio "y coordinate change / x coordinate change".

but y is not changing at all, the change or difference is always 0 no matter what points we pick on the line.

and so, the slope ratio is always "0/...". and that is 0.

so, the slope of that line is 0.

but if there is a typo, then please know : the slope of a line

y =ax + b

is always a (the factor of x).
