Answer:

A. 35.69%

B. 62.77%

Step-by-step explanation:

In this case, what we must do is calculate the probability supported with the data in the table.

Part A.

What is the probability that a randomly selected student is a 7th grader?

Here the total is all the students that would be the sum of all the grades, which are 325 students.

the number of 7th graders is 116, so the probability is:

116/325 = 0.3569

that is, 35.69%

Part B: What percentage of the students interviewed play Video games?

The total number of students is the same 325 and of those 204 play video games, therefore:

204/325 = 0.6277

that is, 62.77%

Find a solution to the linear equation y=6x−18 by filling in the boxes with a valid value of x and y.

juin [17]

You can choose any value for x and find the corresponding y value. So let’s assume x=1.

y=6x-18
y=6(1)-18
y=6-18
y=-12

So a correct ordered pair would be (1,-12).

Which methods could you use to calculate the y-coordinate of the midpointof a vertical line segment with endpoints at (0,0) and

vodka [1.7K]

Answer:

y-coordinate of midpoint of line segment joining the endpoints (0,0) and (0,15) is 7.5

Step-by-step explanation:

Given two end points of line segment that are (0,0) and (0,15). If we have to find the y-coordinate of midpoint of a vertical line segment then we apply mid point formula.

The Midpoint formula is used when one is need to find the exact center point between two given points.

The mid point M of line segment $A(x_{1},y_{1})$ and $B(x_{2},y_{2})$ can be calculated as

$M(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})$

Mid point of line joining the end points (0,0) and (0,15) is

$M(\frac{0+0}{2},\frac{0+15}{2})$ =M(0,7.5)

Hence, y-coordinate of midpoint of line segment joining the endpoints (0,0) and (0,15) is 7.5
