The mean of seven scores 21.Find the sum of all scores .

 

Answer:

147

Step-by-step explanation:

mean = 21

number of scores added = 7

mean is the same as average. Mean is equal to sum of all scores over the number of scores

Mean = (sum of all scores) ÷ (number of scores added)

sum of all scores = (mean) × (number of scores added)

sum of all scores = (21) × (7)

sum of all scores = 147
