All the numbers shown are real.

The answers to problems 4, 7, 11 are irrational, because they are square roots of numbers that are not perfect squares.

The remaining numbers are rational because they are terminating decimals or the square root of a square number.

What measure of center best represents the data set?
inysia [295]
I feel like it would be mean or median, because there is no outlier, making it so that all of the numbers are closely put together.

Put the set into order.

25, 26, 27, 28, 29

So, we know that this is all in order, making it so that we know for sure that there is no outlier. 

If you find the mean, it'll represent the data nicely. 

We know that both the mean and median represent the data set nicely, because it just does. It's one of those things that are extremely painful and hard to fully explain and have someone understand, but don't worry, it makes sense.

So, it can't just be the mean only or the median only.

It also can't be the mode only, because THERE IS NO MODE! 

So, our final answer is mean or median :)

~Hope I helped!~

What is the math outlier ? ***ANSWER PLEASE***
andreyandreev [35.5K]

Answer:

Math:9.75

Science:6

Step-by-step explanation:

Not 100% sure on those answers but here is hot to figure the problem out:

A point that falls outside the data set's inner fences is classified as a minor outlier, while one that falls outside the outer fences is classified as a major outlier. To find the inner fences for your data set, first, multiply the interquartile range by 1.5. Then, add the result to Q3 and subtract it from Q1.

Solve the equation for x by graphing -2x + 3 = -3(-x) - 2
adoni [48]

Answer:

  x = 1

Step-by-step explanation:

There are a couple of ways to solve this. One is to graph the left side of the equation, graph the right side of the equation, and look for the point where those graphs intersect. It is at x = 1. The first attached graph shows this solution.

__

Another method for solving such an equation is to subtract one side from the other and look for the value of x that makes the resulting expression zero.

  (-2x +3) -(-3(-x) -2) = 0

A graphing calculator doesn't need to have this simplified. If it is simplified, it becomes ...

  -5x +5 = 0

So, the graphed line is y = -5x+5. Its x-intercept is x=1, the solution of the original equation. The graph of this is shown in the second attachment.

D=DVDs and G=Games solve for 2D+3G=15.50 and 3D+1G=12.05
kogti [31]

We have

1G = 12.05 - 3D;

Then,

2D + 3( 12.05 - 3D) = 15.50;

2D + 36.15 - 9D = 15.50;

- 7D = - 20.65;

D = 2.95;

Finally, G = 12.05 - 3 x 2.95;

G = 3.20;
