The diver is at -72 because he is below sea level 0. He stops every 15 ft...After the first pause, he is at -72 + 15 = - 57
answer : -57
Surface area is 6s^2, so 6(7^2) is 294. The minimum amount would be 294 inches^2 of wrapper paper.
The range of Ervin's scores is 55.
Range is the difference between the largest number and the smallest number.
To find the range of a set of values, first sort the values numerically (smallest to largest). With this set, it would look like this: 138, 142, 155, 165, 172, 193. Lastly, subtract 138 from 193 to find the range. By doing so, you will get 55 as an answer.
I hope this helps!
