WILL GIVE BRAINLIEST!!! Write the equation represented by the table.
atroni [7]

Answer: y = 2x+12

Step-by-step explanation:

y = mx + b

the Ys are going down by 6 each time

the Xs are going adding up by 3 each time

radio: 6/3 = 2

that's our slope

--------------------------------

when x is 0 then the y will be our b

which is 12

all together

y = 2x+12

You would like to build a relative frequency distribution for this data set to easily compare it to another class of students.
Dafna1 [17]

The relative frequency for the third class, 60 - 69 is equal to 12%.

<h3>What is a class width?</h3>

In a frequency distribution table, a class width can be defined as the difference between the upper (maximum) and lower (minimum) boundaries of any class in a data set. This ultimately implies that, all classes must all have the same width in a frequency distribution table.

<h3>What is a frequency table?</h3>

A frequency table can be used to graphically represent the frequencies or relative frequencies that are associated with a categorical variable.

<h3>How to calculate the relative frequency for the third class, 60 - 69?</h3>

First of all, we would determine the total number of frequency as follows:

Total frequency = 12 + 11 + 6 + 10 + 11

Total frequency = 50.

Mathematically, relative frequency can be calculated by using this formula:

Relative frequency = class frequency/total frequency × 100

Relative frequency = 6/50 × 100

Relative frequency = 0.12 × 100

Relative frequency = 12%.

The Suarez family paid $16.50 for 3 movie tickets. How much would they have paid for 12 tickets?
Dominik [7]

Answer:

It will cost 66 dollars for 12 tickets

Step-by-step explanation:

We can write a ratio to solve.

16.50       x

-------- = ----------

3            12

Using cross products

12 * 16.50 = 3x

198 = 3x

66 = x

It will cost 66 dollars for 12 tickets

I will give brainly but please show how you got the answer when you answer the questions
Angelina_Jolie [31]

Answer: point C = (3.75, 1.5)

Step-by-step explanation:

As the direction of the distance is from A to B, we need to down the y-axis and along (to the right) the x-axis.

Find the distance between the x-coordinates of both points by subtracting the x-coordinate of A from the x-coordinate of B:

5 - 0 = 5

3/4 of the length of this distance = 0.75 x 5 = 3.75

So the x-coordinate of C will be the sum of the distance (3.75) and the x-coordinate of A (as we are "travelling" from A to B):

3.75 + 0 = 3.75

Find the distance between the y-coordinates of both points by subtracting the y-coordinate of B from the y-coordinate of A:

3 - 1 = 2

3/4 of the length of this distance = 0.75 x 2 = 1.5

So the y-coordinate of C will be the y-coordinate of A minus the distance (1.5):

3 - 1.5 = 1.5

Therefore, point C = (3.75, 1.5)

Hope that helps - i dont know what u meant by option 1,2,3 so if u have an questions or i did it wrong i will fix it <3
