We have been given that the standard deviation of a group of 20 scores is 15 and we are asked to find variance.
Since we know variance is square of standard deviation. In order to find out the variance of the given data we have to take the square of 15.

Therefore, our variance is 225.
Answer:
7°F
Step-by-step explanation:
We have the following information from the question;
Morning temperature = -10°F
Increase in temperate = 17°F
Afternoon temperature = the unknown
Since;
Increase in temperature = Afternoon temperature - morning temperature
Then;
Afternoon temperature = increase in temperature + morning temperature
Afternoon temperature = 17°F + (-10°F)
Afternoon temperature= 7°F
Answer:
5 11/85
Step-by-step explanation:
First see how many times a whole number can be found.
436/85 = 5.1294
The denominator goes into the numerator 5 times.
Now we find a new numerator.
436 - (85 * 5) = 11 (this is the amount left over after we made 5 wholes.)
Now we see 5 11/85
It cannot be simplified further.
