otez555 [7]

Answer:

Step-by-step explanation:

She bought two tires for $35.00 each. This means that the total amount for which she bought the tires is

35 × 2 = $70

She later sold them for $65.00 each. This means that the total amount for which she sold the tires is

65 × 2 = $130

Her profit from the tires is

130 - 70 = $60

She bought rims for $75.00 each. This means that the total amount for which she bought the rims is

75 × 2 = $150

She later sold them for $136.00 each. This means that the total amount for which she sold the rims is

136 × 2 = $272

Her profit from selling the rims is

272 - 150 = $122

Her total profit is

60 + 122 = $182

Pani-rosa [81]

Answer:

0.0545 = 5.45% probability that exactly seven are retired people.

Step-by-step explanation:

For each stock investor, there are only two possible outcomes. Either they are retired people, or they are not. Stock investors are independent. This means that 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.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

20% of all stock investors are retired people.

This means that $p = 0.2$

a. What is the probability that exactly seven are retired people?

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 7) = C_{20,7}.(0.2)^{7}.(0.8)^{13} = 0.0545$

0.0545 = 5.45% probability that exactly seven are retired people.
