Answer:

I'm not going to give you the answer because you need to learn this on your own because it isn't hard.

Step-by-step explanation:

There are 4 main things you investigate in a number line: the median, the mode, the range, and mean. The median is the middle of your data set. You find the number of all of your data and find out the middle of that number. You find what line it is in on your data set. The range is the variety of numbers in your data set (for yours its 10). The mean is the average of your data set. The mode is the number that pops up the most (in your case, 2).

All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set Up Equation

3x + 2x + 60° = 180°

Step 2: Solve for x

Combine like terms: 5x + 60 = 180
Isolate x term: 5x = 120
Isolate x: x = 24

Pls help, will give brainliest if your answer is right! Question in image.

Blababa [14]

Step-by-step explanation:

Mean = Average : Sum of the data ÷ Number of data

So find the average number of lates per student

4 = Lates

30 (sum of frequencies) = Frequencies

So 4 ÷ 30 = 7.5

Therefore the answer is 7.5..

PLZ HELP ASAP! IM FAILING SO PLEASEEEE

UkoKoshka [18]

Answer: B

You can find slope by using the slope formula. Because we are already given two coordinate points, we can use that to find our slope. The slope formula is $\frac{y^{2}-y^{1} }{x^{2}-x^{1} }$ . This also refers to $\frac{5-(-5)}{0-4}$ or 10/-4 or -5/2. Any coordinate with the x-value as 0 means that that coordinate is the y-intercept. Because (0,5) has 0 as its x-value, the y-intercept is 5.

Terms/Coefficients
Coordinates (x, y)
Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = -4x + 1

11y = x + 146

Step 2: Solve for x

Substitution

Substitute in y: 11(-4x + 1) = x + 146
Distribute 11: -44x + 11 = x + 146
[Addition Property of Equality] Add 44x on both sides: 11 = 45x + 146
[Subtraction Property of Equality] Subtract 146 on both sides: -135 = 45x
[Division Property of Equality] Divide 45 on both sides: -3 = x
Rewrite/Rearrange: x = -3

Step 3: Solve for y

Define original equation: y = -4x + 1
Substitute in x: y = -4(-3) + 1
Multiply: y = 12 + 1
Add: y = 13
