The answer is 348.00. You have to multiply 7.25 by 24 and then use the product and double it.
Answer:
Mean: Use any 5 numbers that make 25.
Median: 5
Step-by-step explanation:
For the mean you can use 2.5+2.5+2.5+7.5+10
I'm not sure about the median... If it's asking about the median for the set I used, it would be 2.5. If it's asking about the one gives, not including the zero would be 5.
Total = Principal × ( 1 + Rate ) ^ years
(Solved by taking logarithms)
Years = log (total / principal) / (log (1 + rate))
Years = log (684 / 600) / (log 1.07)
Years = log (1.14) / (log (1.07)
Years = 0.0569048513364726 / 0.0293837776852097
Years = 1.9366077414
Answer:
100
Step-by-step explanation:
She wants to average 85, so adding ALL three of her scores, divided by 3 needs to equal 85.
(75 + 80 + x)/3 = 85
Times by 3.
75 + 80 + x = 255
155 + x = 255
subtract 155.
x = 100
She needs 100 on the third test.
