Answer:
8
Step-by-step explanation:
Consider that the way to calculate the mean is the sum total of the values in the series, divided by the number of the series so Mean = SumX / N
We need to calculate the value of the first four numbers and last 3 numbers.
For the first set
5 = X/4 Therefore 5*4 = X so X is 20
For the second set
12 = Y/3 therefore 12*3 = Y so Y is 36
Add them together to get the sum of the full set (remember the calculation for the mean)
36 + 20 = 56
Mean = Sum X (which is 56) / N (which is 7)
So the answer is 56/7 = 8
Answer:
A .The expression 2l+2(3l+1) shows the width is 1 more than 3 times the length.
Step-by-step explanation:
p = 8l + 2
Length = l
Width:
2w = p - 2l
2w = (8l + 2) - 2l
2w = 6l + 2
w = 3l + 1
Therefor w is 3 times the length plus 1
