The distributive property: <em>a(b + c) = ab + ac</em>
2(h + 4) + 6(g + 3) + 5h
= (2)(h) + (2)(4) + (6)(g) + (6)(3) + 5h
= 2h + 8 + 6g + 18 + 5h <em>cimbine like terms</em>
= (2h + 5h) + 6g + (8 + 18)
<h3>= 7h + 6g + 26</h3>
Answer:
The answer is explained below
Step-by-step explanation:
We have the following formulas:
from binomial distibution: P (X = x) = (nCx) * (p) x * (1-p) n-x
from normal distribution: P (X <= x) = (x-np) / sqrT (np (1-p))
Now, n = 25 and p (0.5, 0.6, 0.8), we replace in the formulas and we are left with the following table:
P P(15<=X<=20) P(14.5<=X<=20.5)
0.5 0.2117 is less than 0.2112
0.6 0.5763 is less than 0.5685
0.8 0.5738 is greater than 0.5957
