Question - Many of the students at a school play sports: 17% of students play soccer, 23% play football, & 48% of the football players play soccer. What is the probability that a randomly selected student plays both?

A. 0.0816
B. 0.1104
C. 0.4792
D. 0.4800

Please explain your answer.

Step-by-step explanation:

- 12x + 10 = - 14

- 12x = - 14 - 10

- 12x = - 24

x = - 24 / - 12

x = 2

Hope it will help :)

Answer:

If we are solving for x then the answer is x = 10

Step-by-step explanation:

To solve for x we must first get all the variables to one side

so subtract 1x from both sides

1.50x = 15

divide 1.50 both sides

x = 10

Answer:

The image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).

Step-by-step explanation:

Let suppose the given point is A(18, 9)

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

Rule to calculate the dilation by a scale factor 1/3 centered at the origin

P(x, y) → P'(1/3x, 1/3y)

Here, P'(1/3, 1/3y) is the image of P(x, y).

Thus,

A(18, 9) → A'(1/3(18), 1/3(9)) = A'(6, 3)

Therefore, the image of A(18, 9) after dilation by a scale factor of 1/3 will be: A'(6, 3).

Answer:

The markup amount is $14 and the retail price is $49.

Step-by-step explanation:

You can use the following formula to find the retail price with the information provided:

Retail price=Cost*(100%+markup %)

Cost=35

Markup %=  40%

Now, you can replace the values in the formula:

Retail price=35*(140%)

Retail price=49

Now, you can subtract the cost from the retail price to find the markup amount:

49-35=14

According to this, the answer is that the markup amount is $14 and the retail price is $49.

Step-by-step explanation:

9 divided by 3 = 3

12 divided bye 3 = 4

Answer:

x = 3

Step-by-step explanation:

Since the two legs of the outer triangle equal the same (12), it is safe to assume the two legs of the inner triangle will equal the same. Therefore, x is equal to 3.

Answer:

x=-273

Step-by-step explanation:

first you move the constant to the right. it should look like this(x=652-925)

then you subtract and you should get -273

Answer: C

Step-by-step explanation:

Length = x+6

Width = 2(x+6)

Area = x+6*2x+12

        =  2[tex]x^{2}[/tex]+72

Slope = 2

Y intercept = -3

====================================================

Explanation:

We'll use the template y = mx+b

m = slope

b = y intercept

The y intercept always occurs when x = 0. In this case, b = -3 due to the first row of the table.

The slope is m = 2 because each time we increase x by 1, the y value goes up by 2.

So we can say

m = slope = (rise)/(run) = (change in y)/(change in x) = (2)/(1) = 2

Or we can apply the slope formula

m = (y2-y1)/(x2-x1)

using any two points of the table.

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

Since we know m = 2 and b = -3, this means we get

y = mx+b

y = 2x+(-3)

y = 2x-3

Answer: Total number of those who took part in the survey (T)=2000

Those who were satisfied (t)=1320

Percentage of those who were satisfied (S)=(t/T)*100

S=(1320/2000)*100

S=66%

Therefore only 66% were satisfied

Answer:

There are no simple factors to this expression.  You can however solve for x, giving you:

x = -1 ± √(y + 3)

Step-by-step explanation:

There is no simple pair of factors to this equation, so we'll have to go through the full process.  You can see that by observing that there is no pair of rational numbers that add to make 2 and multiply to make -2.  We can however solve for x:

[tex]y = x^2 + 2x - 2\\y + 2 = x^2 + 2x\\y + 3 = x^2 + 2x + 1\\y + 3 = (x + 1)^2\\(x + 1)^2 = y + 3\\x + 1 = \pm \sqrt{y + 3}\\x = -1 \pm \sqrt{y + 3}[/tex]

Answer:

volume of the new box = 12 x volume of the initial rectangular box

Step-by-step explanation:

Let the length, width and height of the rectangle be represented by l, w and h respectively.

The volume of a rectangle is given as;

volume = l x w x h

             = lwh

From the given question, the dimension of the rectangle are:

new length = l + l = 2l

new width = w + w = 2w

new height = h + h + h = 3h

So that, the volume of the new box is given as;

volume of the new box = 2l x 2w x 3h

                                       = 12 (lwh)

Therefore,

volume of the new box = 12 x volume of the initial rectangular box

Step-by-step explanation:

7.) (0, 2)

Slope of (0, 2) and (-10, -16) = 2 - (-16) ÷ 0 (-10) = 18/10 = 9/5

8.) a. Slope of (17, -12) and (17, 8)

8 - (-12) ÷ 17 - 17 = 20 ÷ 0 = undefined

b. Slope of (6, -2) and (-3, 1)

1 - (-2) ÷ -3 - 6 = 3/-9 = -1/3

9.) (-3, 33) and (4, -9)

-9 - 33 ÷ 4 - (-3) = -42/ 7 = -6

10.)  Hourly: c = 75h + 15

c - charge

h - hours

1 hour

c = 75 (1) + 15

c = 75 + 15 = 90

The hourly charge for services is $90.

Answer:

The required function is:

[tex]C(x) = 150+0.45x[/tex]

Step-by-step explanation:

We have to represent the given scenario as an equation or function

Let x be the number of miles driven in a week

Let C(x) be the function of the number of miles driven

As it is given that charges are 150 per week, these charges are constant so they will be used as it is.

It is also given that the cost of car is 0.45 per mile so for x miles the cost will be:

0.45x

Combining both terms, we get

[tex]C(x) = 150+0.45x[/tex]

Hence,

The required function is:

[tex]C(x) = 150+0.45x[/tex]
