Answer:

The slope would be undefined (16/0)

Step-by-step explanation:

(2, -3) and (2, 13)

13- -3 = 16

2-2 = 0

16 divided by 0 is undefined on a calculator so, undefined is the answer unless you weren't asked to simplify the answer then it would be 16/0.

Answer:

The average of the grade is 7.

Step-by-step explanation:

Add all of the grades up then divide by the number of grades there are

8+8+5=21

21÷3=7

Have a blessed day! I hope my answer was helpful!!

Answer:

The answer is 7

Step-by-step explanation:

So, we need to distribute the mean, (AKA:) average.

There is a rule when finding the average of numbers.

That rule is:

Adding all of the numbers together and dividing that sum by how many numbers there are in total that you added together.

1. First, we to add 8 and 8.

2. 8 + 8 = 16

3. Next, we need add to 5 to that 16.

4. 5 + 16 = 21

5. Since we have 3 numbers, we need to divide that 21 by 3.

6. 21 / 3 = 7

Thus showing that our answer is 7.

When trying to find the mean of numbers, always remember the rule of finding the average.

Answer:

Step-by-step explanation:

From the graph attached,

Relation between the amount of money raised and number of car washed is represented by a straight line.

Let the equation of the line is,

y = mx + b

where m = slope of the line = charges for each car wash

b = y-intercept = Initial amount the team have before the car wash.

Slope of the line will define the charges of car wash for each car.

Since, slope of the line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Therefore, slope of the line passing through (0, 100) and (10, 150) will be,

m = [tex]\frac{150-100}{10-0}[/tex]

m = 5

Therefore, charges of each car wash will be = $5

y-intercept of the line 'b' = 100

Equation of the line will be,

y = 5x + 100

If team wants to earn $300,

300 = 5x + 100

5x = 200

x = 40

Therefore, 40 cars will be needed to wash by the swim team to earn $300.

1) The amount of money the swim team charged for each car that it washed is; $5 per car

2) The amount of money that the swim team had in its account before the car wash is; $100

3) If the team wants to earn $300, then number of cars they need to wash is; 40 cars

We know that formula for slope between two points is;

m = (y₂ - y₁)/(x₂ - x₁)

Let us take 2 coordinates from the given graph which are;

(10, 150) and (30, 250)

Thus;

m = (250 - 150)/(30 - 10)

m = 100/20

m = 5

Now, the equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

From our graph, the y-intercept is 100. Thus, equation of the line of the graph is;

y = 5x + 100

A) From our equation y = 5x + 100, we can say that number of cars are x and as such amount charged per car is $5 per car.

B) The amount of money the swim team had before washing cars is when the value of x is 0. Thus;

y = 5(0) + 100

y = $100

C) The team wants to earn $300 and so we will plug 300 for y into y = 5x + 100 to get;

300 = 5x + 100

5x = 300 - 100

5x = 200

x = 200/5

x = 40 cars.

Answer:

Each hamburger cost 7 dollars.

Answer:

1. The mean amount that this farmer will earn over a long period of years is:

$57,100

2. It makes sense financially for the farmer to buy the insurance.   In a year of drought, he earns only $5,200.  If he spends on insurance premium, his earnings are reduced by $2,000 to $3,200 but the insurance reimbursement will take his overall net earnings to $23,200 ($3,200 + $20,000).  Incurring the insurance expense is highly justified.

Step-by-step explanation:

Earnings in a typical year = $75,000

Earnings in a wet year = $48,000

Earnings in a drought = $26,000

Pro

                         Typical            Wet           Drought

Earnings          $75,000       $48,000      $26,000

Probability        0.50              0.30             0.20

Expected

 earnings       $37,500       $14,400        $5,200

Mean earnings = $57,100

Insurance expense                                 $2,000

Net earnings after insurance expense $3,200

Insurance Reimbursement                  $20,000

Net earnings                                         $23,200

Answer:

In this case, we can write the mean value as:

MV = ∑pₙxₙ - $2

Where pₙ is the probability of event xₙ

in this case we consider only two events:

x₁ = winning $100,000,000, p₁ = 1/189,000,000

x₂ = not winning (or winning $0.0), p₂ = 1 - p₁.

Then the mean value of the ticket is:

MV = $100,000,000*1/189,000,000 + 0*(1 - 1/189,000,000) - $2 = $0.53 - $2

MV = -$1.47

b) At what point the mean value becomes positive?

Well, if the ticket costs less than $0.53, the value would become positive.

if we also consider other possible prices, we will have other positive components in the sum above, then the mean value may become positive.

Now, you may notices that it does not matter if you buy N tickets, the mean value will always be negative becuase:

MV = N*$0.56 - N*$2 = N*-$1.47

This is because yes, as more tickets you buy, the more probabilities of winning the prize you have, but if you buy N tickets, you need to pay N times $2, so the mean value actually decreases.

The grade on the fifth test that will give you a mean score of at least 85 is 87

Step-by-step explanation:

From the question, the grades on 4 math tests are 79,85,86, and 88.

To determine the grade on the fifth test that will give a mean score of at least 85,

Let the grade on the fifth test be x,

From the formula for mean

Mean = Sum of terms / Number of terms

That is,

85 = (79 + 85 + 86 + 88 + x) / 5

[tex]85 = \frac{79 + 85 + 86 + 88 + x}{5}[/tex]

[tex]85 = \frac{338 + x}{5}[/tex]

[tex]338 + x = 85 \times 5[/tex]

[tex]338 + x = 425\\[/tex]

[tex]x = 425 - 338[/tex]

[tex]x = 87[/tex]

x = 87

Hence, the grade on the fifth test that will give you a mean score of at least 85 is 87.
