Which measure describes how much a sample mean varies when different samples are chosen?

Answer:

2.5 miles

Step-by-step explanation:

64/8=20/x

8=20/x

*x    *x

8x=20

/8    /8

x=20/8

x=5/2 or 2.5

Answer:

d is the answer of the question

Answer:

If equal to 90 x is 4

Step-by-step explanation:

Answer:

you have to use the Pythagorean theorem. a^2 + b^2= c^2

72^2 + b^2 = 75^2

5184 + b^2 = 5625 (subtract 5184 from both sides)

b^2= 441 (find the square root of each side)

b= 21

Answer:

y = -5

Step-by-step explanation:

slope of 0 means m = 0 in y intercept form y = mx + b.

they have given you (3, -5), plug these in and solve for your equation.

remember, a line that has a 0 slope means it is a horizontal line.

y = mx + b

-5 = 0(3) + b

-5 = b

so you have, y = -5.

Answer:

Between 85 and 100

Step-by-step explanation:

Getting this will get the average between the required numbers since the average of 83 and 87 is 85, getting 85 will keep the answer at 85 and getting 100 will get the average at 90.

Step-by-step explanation:

Answer:

x=2, y=1

Step-by-step explanation:

Add:

2x+4y=8

+10x-4y=16

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

12x=24

Divide by 12 on both sides:

x=2

Substitute x with 2 on either 2x+4y=8 or 10x-4y=16 it doesn't matter it will result in the same answer.

(I will do both of them to prove it but you only need to replace x with one of the equation)

For 2x+4y=8

2(2)+4y=8

4+4y=8

Subtract 4 on both sides

-4+4+4y=8-4

4y=4

Divide 4 on both sides:

y=1

For 10x-4y=16

10(2)-4y=16

20-4y=16

-20+20-4y=16-20

-4y=-4

Divide -4 on both sides:

y=1

The answer for both 2x + 4y = 8 and 10x – 4y = 16 are the same showing that it doesn't matter which equation you replace the number with it will still result you in the same answer

Hope this helps!

Answer:

5 35/72 kilometers

Step-by-step explanation:

The distance around a lake is 6 7/12 kilometers. Evan rode his bike 5/6 of the distance around the lake. What is the distance in kilometers that Evan rode

This is calculated as:

Total distance = 6 7/12 km

Evan rode = 5/6 of the distance

Hence:

The distance Evans rode is

5/6 of 6 7/12

= 5/6 × 79/12

= 395/72

= 5 35/72 km(kilometers)

Answer: C. 10.

Step-by-step explanation:

Let x = Number of times you have to go to the gym in order for it to cost the same amount.

Given: Monthly pass fee = $90

Additional charge = $4

Total amount = (Monthly fee)  + (Number of times) (Additional charge)

Total amount = 90+4x                (i)

Payment for each time you go to the gym = $13

Total amount = 13x                    (ii)

From (i) and (ii) , we get

[tex]13x=90+4x\\\\\Rightarrow\ 13x-4x=90\\\\\Rightarrow\ 9x=90\\\\\Rightarrow\ x=\dfrac{90}{9}\\\\ \Rightarrow\ x= 10[/tex]

Hence, the number of times you have to go to the gym in order for it to cost the same amount= 10

Hence, the correct option is C. 10.

Answer:

[tex]G.\ $a\left(b+c\right)=ab+ac$[/tex]

Step-by-step explanation:

Given

[tex]F.\ $a\left(b+c\right)=ab+c$[/tex]

[tex]G.\ $a\left(b+c\right)=ab+ac$[/tex]

[tex]H.\ $a+\left(b+c\right)=\left(a+b\right)+\left(a+c\right)$[/tex]

[tex]I.\ $a+\left(b+c\right)=\left(a+b\right)\cdot\left(a+c\right)$[/tex]

Required

Which of the options shows Distributive Property

Distributive property states that

For: [tex]a(b + c)[/tex]

The equivalent is: [tex]ab + ac[/tex]

In other words:

[tex]a(b + c) = ab + ac[/tex] ----- (1)

Having mentioned that;

Next, we compare the list of given options to (1) above

Option G matches (1).

[tex]G.\ $a\left(b+c\right)=ab+ac$[/tex]

Hence, option G correctly demonstrates distributive property
