4*15=60
19*7=133
133-60=73
the shaded area is 73

48 is the correct answer because your going to only do the square
To solve the
following problems, we use the binomial probability equation:
P (r) = [n!/(n-r)!
r!] p^r q^(n-r)
where,
n = total
number of households = 8
r = number of
sample
p =
probability of success = 65% = 0.65
q = probability
of failure = 0.35
A. r = 5
P (r=5) = [8!
/ 3! 5!] 0.65^5 0.35^3
P (r=5) =
0.28
B. r >5
P (r=6) = [8!
/ 2! 6!] 0.65^6 0.35^2
P (r=6) =
0.26
P (r=7) = [8!
/ 1! 7!] 0.65^7 0.35^1
P (r=7) =
0.14
P (r=8) = [8!
/ 0! 8!] 0.65^8 0.35^0
P (r=8) =
0.03
Therefore
total is:
P (r>5) = 0.26
+ 0.14 + 0.03 = 0.43
C. r ≤ 5
P (r ≤ 5) = 1
- P (r>5)
P (r ≤ 5) = 1
– 0.43
P (r ≤ 5) =
0.57

For the answer to the question above,
<span>Sample mean is given by,
x = (1/n)∑x˅i .... ˅ means sub
x = (1/5)(60 + 40 + 35 + 45 + 39)
= 43.8
z-score is given by,
z = (X - μ)/σ .... μ is population mean, σ is the standard deviation
z = (43.8 - 43.8)/8.7
= 0
</span>so the answer is zero
I hope my answer helped you.
