Answer:

<u>1/ 130 is the probability that they are the 4 oldest people in the group. </u>

Step-by-step explanation:

In the question, we are given; group of 11 people, 4 are selected randomly, find probability they are the 4 oldest people from the group

P(O)= <em>favorable number of outcomes / total number of outcomes </em>

<h3>= 1 / 11C4</h3>

=  11! / (11-4)! 4!

=  7! *4! / 11!

=1/ 130

<em>Therefore, 1 / 130 is the probability that they are the 4 oldest people in the group. </em>

slega [8]

Answer:

(7, 4)

Step-by-step explanation:

If point C is being translated to the right 2, the x coordinate will increase by 2. But, the y coordinate will stay the same.

Find the coordinates of C' by adding 2 to the original x coordinate:

5 + 2 = 7

The y coordinate will still be 4.

So, the coordinates of C' will be (7, 4)

Bill can type 19 words per minute faster than bob. their combined typing speed is 97 words per minute. find bobs typing speed
Marina86 [1]

Answer:

Bob's typing speed is 39 words per minute.

Bill's typing speed is 58 words per minute.

Step-by-step explanation:

<u>Given : </u>

Bill can type 19 words per minute faster than bob. their combined typing speed is 97 words per minute.

<u>To Find : </u>

Bobs typing speed

<u>Solution : </u>

Let the bobs typing speed is x

According to the given question :

Bobs typing speed is x

Bill's typing speed is 19+x

Their combined speed is 97 words per minute.

<u>Solving value x : </u>

x + 19+x = 97

2x + 19 = 97

2x = 97 - 19

2x = 78

x = 78/2

x = 39

Bobs typing speed = 39

Bill's typing speed 39 + 19 = 58

Hence, Bobs speed is 39 words per minute.

Which of the following equations has the same solutions as the equations 3x+2y=-12
Marianna [84]

B, C, E, F

<h2>Explanation:</h2>

In this problem, we have the following equation of a line written in Standard form:

3x+2y=-12

So  we need to choose the equations that has the same solutions as this equation. If we multiply each equation by a constant term and find the same solution as the given equation, then they will have the same solution. This is only true fro options B, C, E and F.

Option B.

-3x-2y= 12 \\ \\ Multiply \ both \ sides \ by \ -1: \\ \\ (-1)(-3x-2y)=(-1)(12) \\ \\ 3x+2y=-12

So we get the same given equation. This option is valid!

Option D.

15x+10y= -60 \\ \\ Multiply \ both \ sides \ by \ 1/5: \\ \\ (\frac{1}{5})(15x+10y)=(\frac{1}{5})(-60) \\ \\ 3x+2y=-12

So we get the same given equation. This option is valid!

Option E.

6x+2y= -12 \\ \\ Multiply \ both \ sides \ by \ 1/2: \\ \\ (\frac{1}{2})(6x+2y)=(\frac{1}{2})(-24) \\ \\ 3x+2y=-12

So we get the same given equation. This option is valid!

Option F.

1.5x+y= -6 \\ \\ Multiply \ both \ sides \ by \ 2: \\ \\ (2)(1.5x+y)=(2)(-6) \\ \\ 3x+2y=-12

So we get the same given equation. This option is valid!

For the other options, there is no any constant term that multiplies both sides of the equation and gives us the same given equation.
