The IQR of the first period is 15. The IQR of the third period is 1/3 that, 5*(1/3) is equal to 5.
For the third period, Q1 is 78. The expression for Q3 is Q1+IQR
Therefore, 78+5 = 83
Q3 of the third period is 83
Answer:
x³ + 5x² + 5x - 2
Step-by-step explanation:
Combine like terms.
x³ + 3x² − x + 2x² + 6x − 2 =
= x³ + 5x² + 5x - 2
A = 1/2(12)(5) - 1/2(4)(3)
A = 30 - 6
A = 24
answer
24 mm^2
Answer:
40
Step-by-step explanation:
you have to do this first:
10x4=40
The deviation σ in the art book =15.4, the σ in the Science =7.9
Consequently the art book has data further away from the mean when compared to the science book. It will be difficult to have a valid inference.
No, because there is a lot of variability in the art book data
