Mathematics Middle School

Christel wants to know what the most popular color at her school is. She surveys students grades 1,2,3.

Will the sample be representative or biased? And can you please explain how that answer works. Thx! :)

Answers

Answer 1

Answer:

It will be biased.

Step-by-step explanation:

By surveying only grades 1, 2, and 3, she is not taking a representation of the entire school. It is possible that the popular color or the color the students like would change over time and the opinion of the younger kids could be different from that of the older kids. Therefore, the sample is biased unless she surveys students from all grades.

Find the measure of the indicated angle

Answers

Answer:

? = 110

Step-by-step explanation:

We know the one angle is 25 and the other is 45 because the 90 degree angle that is cut off perfectly in the middle.

All angles of a triangle always adds up to 180

Add all the known angles 25 + 45 = 70

Than subtract 180 - 70 = 110

What are like terms? How do you combine them? Whats an example
I NEED HELP ASAP PLEASE

Answers

Answer:

like terms are terms that have the same variable

Step-by-step explanation:

when combining like terms we add their coefficients for example 4x + 5x = (4+5)x=9x

Examples of like terms are:
5d & 7d
3x & 2x
10 & 4
7 & -6

You combine them by simply doing what the equation tells you:
For example:
4d + 6 - 2d + 10
This would simplify to:
2d + 16

This is because I took the like terms, 4d & -2d, and 6 + 10.

4d - 2d = 2d
6 + 10 = 16

So the answer would be:
2d + 16
