<span>The mean of the sample is 50 and the standard deviation is 12. If 5 is subtracted from each of the values the standard deviation will remain the same, as the standard deviation is the distance of each value from the mean. Since all the scores are subtracted by 5, the effective distance from the mean is going to be the same but the mean will be reduced by 5.</span>

2. Delia and Beto left for school at the same time.
Tema [17]

<u>Answer:</u>

Beto will get to the school first.

<u>Step-by-step explanation:</u>

We are given that Delia lives 3/4 mile from school and walks at a pace of

16 minutes per mile.

So Delia takes \frac{3}{4} \times 16 = 12 minutes to reach school.

While Beto lives 3 1/2 miles from school  and bikes at a pace of 3 minutes per mile.

So Beto takes \frac{7}{2} \times 3 = 10.5 minutes to reach school.

Therefore, Beto will get to the school first.
