Answer:

Coffee(time)

Step-by-step explanation:

A function's output variable will be:

output(input)

So we need to find the input variable and the output variable.

We know that when the time of day changes, we get a certain amount of coffee sold. This means that the amount of coffee sold is directly influenced by the time of day.

The time of day then becomes our input as the coffee sold relies on that number.

That leaves coffee sold as our output!

So the best name for a function in this scenario is Coffee(time).

Answer:

It is an example of an observational study.

Step-by-step explanation:

The given number case is example of an observational study.

Observational studies are ones where researchers observe the effect of a risk factor, diagnostic test, treatment or other intervention without trying to change who is or isn't exposed to it. Cohort studies and case control studies are two types of observational studies.

Given:

In a study to support drug discovery for patients with lung cancer, patients were divided into 3 groups based on the severity of the disease.

Smoking and alcohol consumption habits were recorded for all 3 groups.

The above is somehow the example of research which requires an observation which does not change any data.

Answer:

2x(3x+5)+1(3x+5)

Step-by-step explanation:

The distributive law is the law that states that multiplying a number by a group of numbers is the same as doing each multiplication separately. Eg. A(B+C) =AB+AC

In the case of two sets of parenthesis it would look like:

2x(3x+5)+1(3x+5)

Which would give us:

6x^2 +10x +3x+5

6x^2+13x+5

The general format for 2 bracket ones would be:

(A+B) (C+D) =A(C+D) +B(C+D)

where the two terms in the first bracket go outside the second bracket twice individually because each term must be multiplied by all terms in the other bracket.

Answer:

She will donate P-50/3 each time

Step-by-step explanation:

Now assuming total donation needed to be in the silver category Is P

We can assume also the three additional and equal donations be Q

So

Then 50 + 3Q = P

So we still don't know P

We can get Q by saying

3Q= P - 50

Q = (P - 50) /3

Answer:

[tex]\huge\boxed{\sf x = 5}[/tex]

Step-by-step explanation:

[tex]\sf 3x + 2= 17[/tex]

Subtracting 2 to both sides

[tex]\sf 3x = 17-2\\3x = 15[/tex]

Dividing both sides by 3

[tex]\sf x = 15/3\\x = 5[/tex]

The correct solution to the equation 3x + 2 = 17 is x = 5.

Let's find the correct solution to the equation 3x + 2 = 17:

Step 1: Subtract 2 from both sides to isolate the term with 'x':

3x + 2 - 2 = 17 - 2

3x = 15

Step 2: Divide both sides by 3 to solve for 'x':

3x / 3 = 15 / 3

x = 5

So, the correct solution to the equation 3x + 2 = 17 is x = 5.

Step-by-step explanation:

Length of YM = 1 - (-6)   [This is it's endpoints]

YM = 1 + 7

YM = 8

Length of PW = 9 - 5    [Subtraction of endpoints to get the length]

PW = 4

Answer: 3

Explanation: Here we're asked to evaluate [tex]\frac{c}{a}[/tex] if c = 6 and a = 2.

[tex]\frac{c}{a}[/tex] means the same thing as c divided by a and since we know that c = 6

and a = 2, we can substitute 6 in for c and 2 in for a and we have [tex]\frac{6}{2}[/tex] which is 3.

Answer: 6

Step-by-step explanation:

{3, 2, 2, 12, 6, 5, 14, 4}

To find the mean,add everything up, the divide it by how many numbers you added up.

So, do :

3 + 2 + 2 + 12 + 6 + 5 + 14 + 4 = 48

Then, because you added 8 numbers together, you would divide 8 from 48.

48 ÷ 8 = 6

So, your mean is  6

Answer:

B

Step-by-step explanation:

∠ CBD = ∠ ABE ( vertical angles ), thus

7x - 6 = 5x + 14 ( subtract 5x from both sides )

2x - 6 = 14 ( add 6 to both sides )

2x = 20 ( divide both sides by 2 )

x = 10

Thus

∠ ABE = 5x + 14 = 5(10) + 14 = 50 + 14 = 64° → B

C is the correct option

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the wallpaper be a rectangle

Area of a rectangle = Length * Width

A = LW

Perimeter P = 2L+2W

If the wallpaper is sold in rolls that are 2 feet wide, then the width is 2 feet, to get the length, substitute W = 2 and P = 60 into the formula for calculating the perimeter of a rectangle.

60 = 2L + 2(2)

60 = 2L + 4

2L = 60-4

2L = 56

L = 56/2

L = 28

The minimum length that will be purchased to cover the wall is 28 feet

Answer: $14.85

Step-by-step explanation:

given data:

yearly earnings = $38,600

there are 52weeks in a year, so his weekly wages

= $38,600/52

= $742.31

his state tax rate falls under the 2% rate due to his income

= 2/100 * $38,600

= $772/52

= $14.85 is withheld from his weekly wages for the state tax.
