Let x be the random variable representing defective phone. Let n be the sample size. Let p be the probability that phone is defective.
Given: n=500, p= 0.02
From given information we know that x is random variable such that p is the probability of success and it is constant for each trial. Sample size n is fixed.
X follows Binomial distribution with parameters n=500 and p=0.02
a). The average number of defective phone
E(x) = n*p = 500 * 0.02 = 10
The average number of defective phones is 10.
b)Probability of getting 5 defective phones.
P(X=5) =
=
= 0.037
The probability of getting exactly 5 defective is 0.037.
Answer:
C. 1796.08
Step-by-step explanation:
Area of circle is , r is the radius
remember radius is from the center to the edge, so it is half the diameter
now we need to find the area of the large circle (table) minus the small circle (hole)
the radius of the large circle is 48/2 which is 24
the area is replacing r in the formula with 24, the radius. Using 3.14 as pi, the answer is 1808.64
the radius of the small circle is 4/2 which is 2
the area is so the calculated value would be 12.56
now subtract the area of the hole (small circle) from the area of the table (large circle)
1808.64 - 12.56 = 1796.08
and there's your answer
hope that helps, lmk if it doesn't :)
