For the question in the photo:
y = 2.50x + 7.50

Domains:
0, 2, 3, 4, 5, 6, 7, 8, 9, 10

As you can’t ride 0.2 or 0.7 of a ride, for example, and you only have time for ten rides. Plus you have enough money to ride ten rides

For the drama club one:

C = 21t + 40

Is the correct answer as 40 is a set value and is not influenced by the amount of club members there are, x is the amount per shirt, and C is the cost

Which statements are true about the ordered pair

Lostsunrise [7]

Answer:

-The ordered pair (-1, 5) is a solution to the first equation because it makes the first equation true.

-The ordered pair (-1, 5) is a solution to the second equation because it makes the second equation true.

-The ordered pair (-1, 5) is a solution to the system because it makes both equations true

Step-by-step explanation:

The correct question is

Which statements are true about the ordered pair (−1, 5) and the system of equations?

x+y=4

x−y=−6

we know that

If a ordered pair is a solution of a equation, then the ordered pair, must satisfy the equation (makes the equation true)

If a ordered pair is a solution of the system of equations, then the ordered pair, must satisfy the equations of the system (makes both equations true)

we have

$x+y=4$ ----> first equation

$x-y=-6$ ----> second equation

step 1

Verify if the ordered pair satisfy the first equation

Substitute the values of x and y of the ordered pair in the first equation

For x=-1, y=5

$-1+5=4$

$4=4$ ---> is true

The ordered pair satisfy the first equation

The ordered pair is a solution to the first equation because it makes the first equation true

step 2

Verify if the ordered pair satisfy the second equation

Substitute the values of x and y of the ordered pair in the second equation

For x=-1, y=5

$-1-5=-6$

$-6=-6$ ---> is true

The ordered pair satisfy the second equation

The ordered pair is a solution to the second equation because it makes the second equation true

therefore

The ordered pair (-1, 5) is a solution to the system because it makes both equations true

Which is the better value 36 pictures for $8 or 24 pictures for $5

diamong [38]

Answer:

24 pictures for $5

Step-by-step explanation:

To find out the better value, we have to find the price of a singular picture. To do this, we will divide each number by the amount of pictures.

For the first deal, 36 pictures cost $8, so 1 picture costs about $0.22.

For the second deal, 24 pictures cost $5, so 1 picture costs about $0.21.

Since the second deal costs less, it is a better deal.

You represent a chemical company that is being sued for paint damage to automobiles. You want to support the claim that the mean

denpristay [2]

Correct question is;

You represent a chemical company that is being sued for paint damage to automobiles. You want to support the claim that the mean repair cost per automobile is more than $650. How would you write the null and alternative hypotheses?

A) State the null and alternative hypotheses in words (context of the problem)

B) Write the null and alternative hypotheses in appropriate symbols (population parameters μ, σ or p)

C) Describe in words Type I error (the consequence of rejecting a true null hypothesis.)

D) Describe in words Type II error (the consequence of failing to reject a false null hypothesis.)

Answer:

A)In words;

Null hypothesis is that the cost is $650

Alternative hypothesis is that the cost is not $650

B) Null hypothesis; μ = 650

Alternative hypothesis; μ ≠ 650

C) Type I Error will be to make a claim that the repair cost is not $650, when it is actually $650.

D) Type II Error will be to make a claim that the repair cost is not $650, but fail to reject the claim that it is $650.

Step-by-step explanation:

We are told that You want to support the claim that the mean repair cost per automobile is more than $650.

Thus;

A)In words;

Null hypothesis is that the cost is $650

Alternative hypothesis is that the cost is not $650

B) Null hypothesis; μ = 650

Alternative hypothesis; μ ≠ 650

C) Type I Error will be to make a claim that the repair cost is not $650, when it is actually $650.

D) Type II Error will be to make a claim that the repair cost is not $650, but fail to reject the claim that it is $650.

melomori [17]

We will have the following:

* If Kristin does not decrease the price of her cakes, her projected weekly revenue from cake sales will be $2500.

*If Kristin decreases the price of her cakes, her projected weekly revalue will be $2520.

*Kristin will obtain the same revenue if she sells the cakes for $24 or $21.
