Step-by-step explanation:The fine schedule for overdue books at the county library is modeled by the values in the table.

Library Fines for Overdue Books

Days overdue

Amount of fine

0

0 ¢

2

5 ¢

4

10 ¢

6

15 ¢

8

20 ¢

10

25 ¢

Which equation best models the fine schedule for overdue books?

y = five-halves x, where x is the cost in cents for a book that is y days overdue

y = five-halves x, where y is the cost in cents for a book that is x days overdue

y = 5 x, where x is the cost in cents for a book that is y days overdue

y = 5 x, where y is the cost in cents for a book that is x days overdue

Suppose that 1% of all computers of a certain type experience CPU failure during the warranty period. If a simple random sample

Answer:

A)

μ = 5

σ = 2.2

B)

P(0) = 0.0066

C)

P(x ≥ 4) = 0.74

Step-by-step explanation:

A) The expected value is going to be the same as the mean μ.

We can use the binomial probability distribution because there are a fixed number of trials (500), each trial is independent and there are only two possible outcomes (CPU failure or not) and the probability of failure has the fixed value 0.01.

For binomial distributions:

μ = np, where p is the probability (in this case of CPU failure) and n is the number of trials (500)

μ = (500)(0.01) = 5

σ = $\sqrt{npq}$ , where q = 1 - p

σ = $\sqrt{(500)(0.01)(0.99)}$ = 2.2

B) We can use the binomial probability formula

$P(x)=(\frac{n!}{(n-x)!x!})$ × pˣ × qⁿ⁻ˣ

$P(0)=(\frac{500!}{(500-0)!0!})$ × 0.01⁰ × 0.99⁵⁰⁰

C) In this case wee need to use a binomial distribution calculator. Setting n as 500, π = 0.01 and finding the probability above 3.

Profit is always calculated as revenue minus expenses. If a company’s expenses were $10 million, write an equation that expresse

ivann1987 [24]

The equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars) is P = R - 10

The profit is $15 million when revenue is $25 million

Step-by-step explanation:

The formula of the profit is P = R - E, where

R is the revenue
E is the expenses

If a company’s expenses were $10 million, wee need to write an equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars) and then find the profit when revenue is $25 million

∵ P is the profit in millions of dollars

∵ R is the revenue in millions of dollars

∵ The expenses E were $10 million

∵ Profit = Revenue - Expenses

∴ P = R - 10

The equation that expresses profit, P, (in millions of dollars) in terms of revenue, R, (in millions of dollars) is P = R - 10

∵ The revenue R = $25 million

∵ P = R - 10

- Substitute the value of R in the equation

∴ P = 25 - 10

∴ P = 15

∴ The profit is $15 million

The profit is $15 million when revenue is $25 million
