**Answer 1**

**Answer:**

**Step-by-step explanation:**

Total for football: 9 +7

Total for figure skating: 12 +7

NEW Total for football: 16

NEW Total for figure skating: 19

The question says that 9 people like football

The question says that 12 people like to watch figure skating

The question also says that 7 people like to watch both, and because of that, you should add 7 to both 9 and 12, but keep the new numbers separated from each other. So once we know the sum of 9 +7 is 16, and 12 + 7 is 19, we can subtract the two numbers, and get 3 as the answer. Because you are counting the number of times that you have to travel up or down to the other number, and so if you are on a set of stairs that go up to the 16 level and you are on the 14th level, you need to travel up 2 sets of stairs to get to level 16.

Hope that example helps and can help in the future with other problems!

What is the probability that one randomly selected physician is a man or is 35-44 years old

### Answers

**Answer:**

28%

**Step-by-step explanation:**

Joyfoyfoyfyfrugifgpuyg

Based on this table, the probability that the physician is a man is 78%

Now, if the physician is a man and 35-44 years old, he’s already included in that 78%, so we only need to now consider the possibility that they physician is female and 35-44 years old: 8%.

So the total probability is 78% (male) + 8% (female and 35-44) = 80%

This can also be found by adding up all the individual probabilities in your table:

### Answers

**Answer:**

7/3

**Step-by-step explanation:**

f(x) =7/(x+2)

g(x) = (x + 5)^2

f(g(-4))=

First find g(-4)

g(-4) = (-4+5)^2

=(1)^2 =1

Triangle ABC is a right triangle. What is the length of AC?

### Answers

**Answer:**

AC = [tex]\sqrt{58}[/tex]

**Step-by-step explanation:**

Calculate AC using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A (0, - 2) and (x₂, y₂ ) = C (3, 5 )

AC = [tex]\sqrt{(3-0)^2+(5-(-2)})^2[/tex]

= [tex]\sqrt{3^2+(5+2)^2}[/tex]

= [tex]\sqrt{9+7^2}[/tex]

= [tex]\sqrt{9+49}[/tex]

= [tex]\sqrt{58}[/tex]

what is the formula for speed when speed isnt given

### Answers

**Step-by-step explanation:**

what do you mean lf speed is not given what we have tofind

**Answer:**

v = d/t, perhaps.

**Step-by-step explanation:**

Velocity (speed) is defined as distance traveled divided by the time it takes to travel that distance.

This gives an average speed. For example, I'll be taking a trip tomorrow of about 150 miles. If it takes me 3 hours, my average speed is v = 150/3 = 50 miles per hour.

That does not mean my speed is constantly 50 miles per hour; I sometimes go slower than that (maybe even stopping for red lights!), and sometimes I'll be going faster than that.

A lot of school math problems assume a constant speed.

Write the equation of a line in slope-intercept form, y = mx + b, between the following

points: (2, 5) and (-4,-4).

### Answers

**Answer:**

[tex]y = \frac{3}{2} x + 2[/tex]

**Step-by-step explanation:**

In the slope-intercept form y= mx +b, m is the slope and b is the y- intercept.

[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} } [/tex]

Using the formula above,

[tex]slope = \frac{5 - ( - 4)}{2 - ( - 4)} [/tex]

[tex]m = \frac{5 + 4}{2 + 4} [/tex]

[tex]m = \frac{9}{6} [/tex]

[tex]m = \frac{3}{2} [/tex]

Substitute the value of m into the equation:

[tex]y = \frac{3}{2} x + b[/tex]

To find the value of b, substitute a pair of coordinates into the equation.

When x= 2, y= 5,

[tex]5 = \frac{3}{2} (2) + b[/tex]

5= 3 +b

b= 5 -3

b= 2

Thus, the equation of the line is [tex]y = \frac{3}{2} x + 2[/tex].

R 3. The mean of 4 numbers is 8. Three of the numbers add up to 22. What is the last number?

### Answers

*Solution* :

let the last number be **x**** **

**we**** ****know****,**

[tex] \boxed{mean = \frac{sum \: \: of \: \: all \: \: observations}{number \: \: of \: \: observations} }[/tex]

So,

[tex] \hookrightarrow \: 8 = \dfrac{22 + x}{4} [/tex]

[tex] \hookrightarrow \: 8 \times 4 = 22 + x[/tex]

[tex] \hookrightarrow \: 32 = 22 + x[/tex]

[tex] \hookrightarrow \: x = 32 - 22[/tex]

[tex] \hookrightarrow \: x = 10[/tex]

therefore, the last number is **10****.**

(EASY) In a rectangle, the length is 5 metres more than the width The perimeter of the rectangle is 70 metres Calculate the measurments for the length and width

### Answers

**Answer:**

15 m and 20 m

**Step-by-step explanation:**

Let the width be x

Length = x + 5

Perimeter = 2(l + b)

70 = 2(x + 5 + x)

70/2 = 2x + 5

35 = 2x + 5

35 - 5 = 2x

30 = 2x

30/2 = x

15 = x

Length = x + 5 = 20 m

Breadth = x = 15 m
