(C), because in a function you cannot repeat any of the x factors, in all A B and D you see that they repeat a number in the x, therefore the only answer choice left is C.

Answer:

The correct option is C.

Step-by-step explanation:

Consider the provided information.

A function is defined as a relation of input and output where each input has only one possible output or Each x value is associated with only one y value.

Now consider the provided tables

Option A has two y values for x = -15. i.e 16 and 22. Thus, this is not a function.

Option B has two y values for x = -3 i.e 16 and 15. Thus, this is not a function.

Option C has only one y values for each x value. Thus, this is a function.

Option D has two y values for x = -7 i.e 14 and 15. Thus, this is not a function.

Hence, the correct option is C.

. A construction company wants to submit a bid for remodeling a school. The research and planning needed to make the bid cost $4

Elenna [48]

Answer:

This project has a positive Expected Monetary Value, so it is expected to make money. This means that the company should be advised to make the bid.

Step-by-step explanation:

We have to find the expected monetary value of this project.

If it is positive, the company should make the bid. Otherwise, they should not make the bid.

There is a 20% probability of the bid being accepted. If the bid is accepted, the company would make $26,000 and lose $4,000. So the expected net earning is $26,000-$4,000 = $22,000.

There is an 80% probability of the bid being rejected. In this case, the company loses $4,000.

The Expected Monetary Value of the project is:

$EMV = 0.2(22,000) + 0.8(-4,000) = $1,200$ .

This project has a positive Expected Monetary Value, so it is expected to make money. This means that the company should be advised to make the bid.

Develop an estimate for each of the following situations.(at) The cost of a 500-mile automobile trip, if gaso-line is $4 per gal

Olin [163]

Answer:

The answer is below

Step-by-step explanation:

develop an estimate for each of the following situations.

(a) The cost of a 500- mile automobile trip, if gasoline is $4.00 per gallon, vehicle wear and tear is $0.65 per mile, and our vehicle gets 25 miles per gallon.

(b) The total number of hours in the average human life, if the average life is 75 years.

(c) The number of days it takes to travel around the equator using a hot air balloon, if the balloon averages 100 miles per day, the diameter of the earth is ~4,000 miles.

Solution:

a) The total trip = 500 mile

Cost of wear and tear = $0.65 per mile = $0.65 * 500 mile = $325

25 miles takes 1 gallon of gasoline at a cost of $4 per gallon

Cost of gasoline = $4 per gallon * 500 miles / 25 miles per gallon = $80

cost of a 500-mile automobile trip = Cost of wear and tear + Cost of gasoline = $325 + $80 = $405

b) Average life of human = 75 years.

1 year = 365 days, 1 day = 24 hours

Average life of human in hours = 75 years * 365 days * 24 hours =657000 hours

c) Diameter of earth = 4000 miles

Distance of equator = diameter of earth = 4000 miles

100 mile per day

number of days for the balloon to travel round the earth = 4000 miles / (100 mile per day) = 40 days

Simplify the product.

liberstina [14]

The value of the product expression is –6p^3 + 8p^2 – 10p

<h3>How to simplify the product?</h3>

The product expression is given as:

2p(–3p2 + 4p – 5)

Rewrite properly as:

2p(–3p^2 + 4p – 5)

Remove the bracket

2p * –3p^2 + 2p * 4p – 2p * 5

Evaluate the products

–6p^3 + 8p^2 – 10p

Hence, the value of the product expression is –6p^3 + 8p^2 – 10p
