Answer:

75.0%

Step-by-step explanation:

There are a total of 69+59 = 128 people in the group. Of those, 69 are men and 27 more are people (women) who earn more than $50,000. So the group (man or person earning more than $50,000) consists of 96 people.

The probability of selecting one of those 96 from the group of 128 is ...

96/128 = 3/4 = 75.0%

_____

In a problem such as this, where the group of interest consists of parts of overlapping groups, the trick is always to find the easiest way to determine the size of the group of interest. Since the group "men" includes "high-earning men" and "low-earning men" and the group "women" includes "high-earning women" and "low-earning women", we could go to the trouble to figure the numbers in each of those four groups. In the end, we want ...

man or high-earner = "low-earning man" + "high-earning man" + "high-earning woman"

As we saw above, the sum of the first two of these is just "men", so we can find the size of our group of interest by adding ...

= "men" + "high-earning women"

Answer:

Apply BODMAS

Step-by-step explanation:

PLEASE FIND THE PICTURE BELLOW

SOLUTION STEPS

(4⋅2−10x−24)(2x+3)

Multiply 4 and 2 to get 8.

(8−10x−24)(2x+3)

Subtract 24 from 8 to get −16.

(−16−10x)(2x+3)

Apply the distributive property by multiplying each term of −16−10x by each term of 2x+3.

−32x−48−20x

2

−30x

Combine −32x and −30x to get −62x.

−62x−48−20x

An amusement park charges admission plus a fee for each ride. Admission plus four ride cost $22. Admission plus seven ride cost

nignag [31]

Answer:

Admission fee charged = $3

Cost of each ride = $10

Step-by-step explanation:

Let admission fee charged by amusement park in dollars be = $x$

Let cost of each ride in dollars be = $y$

Given:

Admission plus four rides cost $22

If each ride cost in dollars = $y$

Cost of 4 rides in dollars will be = $4y$

So, the total cost in dollars will be given as = $x+4y$

So, we have

$x+4y=22$

Admission plus seven ride cost $31.

If each ride cost in dollars = $y$

Cost of 7 rides in dollars will be = $7y$

So, the total cost in dollars will be given as = $x+7y$

So, we have

$x+7y=31$

So, we have the system of equation as:

A) $x+4y=22$

B) $x+7y=31$

Solving the system by elimination method.

Eliminating $x$ by subtracting equation A from B.

$x+7y=31$

- $x+4y=22$

- - - [Sign of each term of subtract-ant gets reversed]

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

$3y=9$

Dividing both sides by 3.

$\frac{3y}{3}=\frac{9}{3}$

∴ $y=3$

Plugging in $y=3$ in equation A.

$x+4(3)=22$

$x+12=22$

Subtracting both sides by 12.

$x+12-12=22-12$

∴ $x=10$

Thus, admission fee charged = $3

Cost of each ride = $10
