Create a data set that has five values. The mean of the data set should be 34.

Answers

Answer 1
Answer:

Answer:

A = {32, 36, 34, 33, 35};

Step-by-step explanation:

The general definition of mean of a set A is:

mean = (x_1 + x_2 + x_3 + ... + x_n)/(n), where n are the elements of the dataset.

In this case:

  • A= {32, 36, 34, 33, 35};
  • n = 5

mean = (32 + 36 + 34 + 33 +35)/(5)  = (170)/(5) = 34

mean = 34
Answer 2
Answer: So if it Has a mean of 34 then whot is 34 divided by 5 and then the ansere for that is the first number of the data set, and then do 34 divided by 4 and then the ansere for that is the second number of the data set, and then do 34 divided by 3, 34 divided by 2 then 34 divided bye 6. Hop this helps.

Eight friends went to a hockey game. The price of admission per person was $x. Four of the friends paid an extra $6 each for a player guide book. Write and simplify an expression that represents the total cost.

Answers

The expression that represents the totalcost is 8x + 24.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of friends = 8

Price of admission per person = x

Number of friends who paid an extra $6 = 4

The total cost of 8 friends.

= 8x + 6 x 4

= 8x + 24

Thus,

The totalcost is 8x + 24.

-3.1x+7-7.4x=1.5x+6(x-3/2

Answers

Answer:

x=8/9

Step-by-step explanation:

-3.1x+7-7.4x=1.5x+6(x-3/2)

-3.1x-7.4x+7=1.5x+6x-9

-10.5x-1.5x-6x=-9-7

-18x=-16

18x=16

x=16/18

simplify

x=8/9

(a) What is the equation of the line, written in slope-intercept form? Show how you determined the equation.

Answers

First we need to find the slope.  We can find the slope by (rise)/(run).  The slope is (-5)/(4).  You can also find the slope by calculating the change in the y values over the change in the x values.  If the line looks like /, it has a positive slope, if it looks like \, it has a negative slope.  

The slope intercept form is y=mx+b

Where m is slope and b is the y-intercept.

To find the y-intercept is (0,16.25) because we take the last y value we know, 15, and add \frac{5/4} (|m|).  So now we just put it all into the equation.  

y=(-5)/(4)x+16.25
