Answer 1

Answer: (3)The average change in temperature each day is 5 degrees. (4) The average number of points relatives to their opponents is 8. (5)The average yearly drop in enrollment is 12. (6) It will take 11 min.

Explanation:

The Formula to find the average is,

$\text{Average}=\frac{\text{Sum of terms}}{\text{Number of terms}}$

(3)

It is given that Total dropped temperature in 7 days is 35.

Since total change in temperature is 35 and number of days is 7.

$\text{Average}=\frac{35}{7}$

$\text{Average change in temperature}=5$

Therefore, the average change in temperature each day is 5 degrees.

(4)

The teams lost by total of 48 points in 6 matches.

Since total points is 48 and number of matches is 6.

$\text{Average points}=\frac{48}{6}$

$\text{Average}=8$

Therefore, the average number of points relatives to their opponents is 8.

(5)

The school dropped by 60 students over 5 years.

The total number of dropped students is 60 and the number of years is 5.

$\text{Average Students}=\frac{60}{5}$

$\text{Average Students}=12$

Therefore, the average yearly drop in enrollment is 12.

(6)

The submarine descends at the rate of 60 feet per min. The total depth is 660.

$\text{Average Time}=\frac{660}{60}$

$\text{Average Time}=11$

Therefore, the submarine will descend 660 feet in 11 min.
