8, 14, 12, 17, 4, 6, 2

Mean = average = (8+ 14 + 12 + 17 + 4 + 6 + 2) / 63 = 63/7 = 9

Answer

Mean = 9

To find the mean,we have to sum up the data given and divide it by the number of data.

In this case,there are in total of 7 datas,therefore the equation would be :

\frac{8 + 14 + 12 + 17 + 4 + 6 + 2}{7} \\ = \frac{63}{7} \\ = 9
Thus,the answer is 9.

Hope it helps!

Determine whether each of the following pairs of angles have equal measures.
Hatshy [7]

The pairs of angles that  have equal measures are:

  • LJP
  • NJR
  • MJP
  • PJR

The pairs of angles that do not  have equal measures are:

  • MJK
  • PJR
  • KJR
  • MJP
  • KJL
  • LJM

<h3>What is an angle?</h3>

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

It is given that:

Both MJK and  PJR can be seen as (Unequal angles)

The angle MJK  is ( 90 degrees), then  angle PJR will be ( 48 + 46 )= 94 degrees

Both LJP and NJR  can be seen as ( Equal angles)

The measure of angle LJP = 48 + 46 + 48 = 142 degrees

The measure of angle NJR = 48 + 48 + 46 = 142 degrees

KJR & MJP = Unequal

The angle KJR will now be [ 360 - (46+48+48+46+90) ]

= 82 degrees

The  angle MJP  will be ( 94 degrees)

Both KJL & LJM  are Unequal, then

The angle KJL  will be  42 degrees, then angle LJM  will be ( 90 - 42 )

= 48 degrees

10) A new car is available in a sedan model and
Dafna11 [192]

Answer:

Option (C) n = 256

Therefore, there are 256 ways to select a car with 2 car models, 8 different colors and any combinations of 4 optional features.

Step-by-step explanation:

A new car is available in a sedan model and a hatchback model.

So that means customers can select the model of the car in,

n₁ = 2 ways

It is available in eight  different colors.

After selecting the model, customers can select the color of the car in,

n₂ = 8 ways

Customers can choose to add any combination of four optional features.

After selecting the color, customers have the choice to add any combination of 4 optional features,

n₃ = 4² = 16 ways

Which means that there are 16 different ways to add 4 optional features e.g.

1. 0, 0, 0, 0

2. 0, 0, 0, 1

3. 0, 0, 1, 0

4. 0, 0, 1, 1

and the list goes on to 16 different ways.

Now the total ways to select a car is given by

n = n₁*n₂*n₃

n = 2*8*16

n = 256

Therefore, there are 256 ways to select a car with 2 car models, 8 different colors and any combinations of 4 optional features.
