Answer:
Data Set A = 6.5
Data Set B = 4
Step-by-step explanation:
The mean is just the average. It's calculated by adding up the scores and dividing the total by the number of scores in the group altogether.
For Data set A, you add 4 + 4 + 5 + 6 + 7 + 8 + 9 + 9 = 52
Then divide the total by how many numbers are in the set.
In this case, 52 ÷ 8 = 6.5
For Data set B, do the same. 3 + 3 + 3 + 4 + 4 + 5 + 5 + 5 = 32 32 ÷ 8 = 4
Answer:
15, inches, 7, inches
Step-by-step explanation:
44=2(8+l)+2l
44=16+4l
28=4l
7=l
l=7
w=8+7
w=15
Interpret the exponent in the formula. S to the third power means to use s as a factor 3 times.
V = S to the third power = S x S x S
Find the volume of the first cube.
Substitute 4 for s.
V = 4 x 4 x 4 = 64
Find the volume of the second cube.
Substitute 7 for s.
V = 7 x 7 x 7 = 343
Tamara's first cube has a volume of 64 cubic centimeters, and her second cube has a volume of 343 cubic centimeters
