A = bh ( b is the base and h the perpendicular height )
Give x is 4 more than 6, that is x = 10 , then
b = x = 10 and h = 2x = 2(10) = 20 , so
A = × 10 × 20 = 5 × 20 = 100 units² → C
Answer:
And replacing we got:
And the best anwer is
10.12
Step-by-step explanation:
We have the following data given:
62 63 68 72 79 80 83 93 94 95
And we need to begin finding the mean with the following formula:
And replacing we got:
Now we can find the mean absolute deviation like this:
And finally we can find the mean abslute deviation with the following formula:
And replacing we got:
And the best anwer is
