Answer:
0.0512
Step-by-step explanation:
For each individual, there are only two possible outomes. Either he receives Social Security, or he does not. The probability of an individual receiving Social Security is independent of other individuals. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
The number of individuals in the sample is 5.
This means that
The probability that an individual receives Social Security is 20%.
This means that
What is the probability that exactly 3 of the 5 individuals receive Social Security?
This is P(X = 3).
Answer:
8

80 X £4.25 = £340
Answer: Down Below
Step-by-step explanation: Solving for -2x^3 + 15x^2 - 22x - 15(x - 3) = 0
Standard form:
−2x3 + 15x2 − 37x + 45 = 0
Factorization:
−(2x − 9)(x2 − 3x + 5) = 0
Answer:
B: congruent to figure A
Step-by-step explanation:
if you reflect figure A across the x-axis the new shape will be the same size and shape as figure A. Which means it is congruent to figure A. So, the answer is B
