Step-by-step explanation:

Given: The mean score for a math test taken by Class A is 84, with the scores ranging from 78 to 94. The mean score for the same math test taken by Class B is 76, with the scores ranging from 68 to 88

a) Incorrect:  The highest score was in Class A which is 94

b) Incorrect: The average of Class A is 84 which is higher than Class B is 76

c) Correct : The average of Class A is 84 which is higher than Class B is 76

d) Incorrect: The difference between highest and lowest scores in Class A is 16(94-78) whereas in Class B its 20(88-68)

The answer is really d

Step-by-step explanation:

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
