Answer:

[(6 + x) / 13+x] = 0.65

7

Step-by-step explanation:

Given that:

Total number of games = 13

Number of correct prediction = 6

Number of correct predictions needed to raise prediction % to 65%

(Number of correct predictions) / (total number of games) = 0.65

Let x = number of additional consecutive correct predictions

[(6 + x) / 13+x] = 0.65

Where x = number of consecutive predictions required

6 + x = (13 + x) * 0.65

6 + x = 8.45 + 0.65x

x - 0.65x = 8.45 - 6

0.35x = 2.45

x = 2.45 / 0.35

x = 7

7 consecutive correct predictions

Bowl 6 games cost $24

Step-by-step explanation:

Proportional Relationship

We have a situation where the cost y in dollars to spend an evening bowling is proportional to the number of games x bowled.

A proportional relationship is written with the equation:

y = k.x

The value of k will be determined by using the given information: 4 games bowled cost $16, thus:

16 = k.(4) = 4k

Solving:

k = 16 / 4 =4

Thus, the function is:

y = 4x

x=6 games bowled cost:

y = 4*6

y = $24

Bowl 6 games cost $24

Answer:

s=27*2+3

Answer:

Results are below.

Step-by-step explanation:

Giving the following information:

Selling price= $60

Unitary variable cost= $28

Fixed costs= $15,000

First, we need to calculate the average total cost:

Average cost= total cost / number of units

For example, for 1 unit and 10,000 units:

1 unit:

Average cost= 15,028/1 = 15,028

10,000 units:

Average cost= (15,000 + 28*10,000) / 10,000

Average cost= $29.5

Now, we can calculate the break-even point in units:

0= (60*x) - (28*x) - 15,000

x= number of units to break-even

0= 32x - 15,000

15,000/32= x

468.75=x

break-even point in units= 469

For the desired profit of $10,000:

10,000 = (60*x) - (28*x) - 15,000

25,000= 32x

781.25= x

Break-even point= 782 units

Finally, fixed costs dropped by $8,000:

0= 32x - 7,000

x= 7,000/32

x= 218.75

Break-even point= 219

Difference= 250 units

Answer:

37

Step-by-step explanation:

3x + 8x + 4x = 6x + 63 ( combine like terms)

>15x = 6x + 63 (subtract from both sides)

-6x. -6x

-----------------

>9x = 63. (divide both sides by 9)

--------------

9. 9

> x = 7 ( use this to plug in for your new equation)!

5(x) + 2

>5(7) + 2 (multiply 5*7)

> 35 +2 (then add)

> 37 is your answer

Answer: K = -14

Step-by-step explanation: solve for k by simplifying both sides of the equation then isolating the variable

Answer:

the correct answer is -15 for the equation:

3(2x − 5) = 6x + k

Answer:

the answer is yes  

because it is within the shaded region of both inequalities

Answer:

180 inches

Step-by-step explanation:

36x5= 180

Answer:

if she already has 36 inches and we are tying to find how much she need we need to take that 5 and multiple it to the 36 because the word TIMES means to multiple so 36x5= 180. so your answer will be she will need 180 in (since that is the measurement we are using)

Step-by-step explanation:

Answer:

It's quite simple, let me explain..

Step-by-step explanation:

The median is the middle of a data set, so you would need to find the exact middle of your data set.

If your data set is odd, and has an odd amount of numbers, just get the number exactly in the middle, and that would be your median. But when your data set has an even amount of numbers, it is a bit tricky.

Here's an example:

85, 78, 96, 83, 77

As you can see, this set has an odd amount of numbers, 5 numbers to be exact. The median would be 96 because it is exactly in the middle.

An example of a data set with even numbers would be this:

1, 2, 3, 4

What you would do is add the two numbers in the middle, and divide by two.

In this case, 2 and three are in the middle, so you would add 2 and 3, which is 5. Then you would divide 5 by two which is 2.5

2.5 Would be your median.

Hopefully this made sense, please ask questions if you have any.

Answer:

[tex]y = 50x + 50[/tex]

Step-by-step explanation:

Given

x = years since 1992.

y = value of pin

This means that

[tex]x = 1[/tex] ----- in 1992

[tex]x_1 = 6[/tex]; [tex]y_1 = 350[/tex] ---- in 1997

[tex]x_2 = 11;[/tex] [tex]y_2 = 600[/tex] ---- in 2002

Required

Determine the line equation in slope intercept form

First, we need to determine the slope (m) of the line

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

[tex]m = \frac{600 - 350}{11- 6}[/tex]

[tex]m = \frac{250}{5}[/tex]

[tex]m = 50[/tex]

The equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

Recall that

[tex]x_1 = 6[/tex]; [tex]y_1 = 350[/tex]

[tex]m = 50[/tex]

So, we have:

[tex]y - 350 = 50(x - 6)[/tex]

[tex]y - 350 = 50x - 300[/tex]

[tex]y = 50x - 300 + 350[/tex]

[tex]y = 50x + 50[/tex]

Answer:

C. The value of a is the number that the x-values are multiplied by to get to the corresponding y-values. So, a = 3.

Step-by-step explanation:

Given the points (5, 15) and (-5, -15) are plotted using the equation y = a•x, this shows a proportional relationship between y and x.

Thus using any of the points, say (5, 15), x = 5, and y = 15, thus:

a = y/x = 15/5

a = 3

Therefore, the value of a, which is 3, is the number that the x-values, 5 and -5, are multiplied by to get the corresponding y-values, 15 and -15.

As we can see, if we multiply each of the x-values by 3, it will give us their corresponding y-values.
