Will give brainliest and 5 stars
BaLLatris [955]
First, find what percentage of students had 3 or more by adding up your known percents:

45% + 23 % + 21% + x% = 100%
x = 11%

Since you're given that 96 students had 2 or more, you add up the percentages of 2 and 3 or more:

11 + 21 = 32%

Now set up a proportion that relates it to the whole:

\frac{96 students}{32 percent} = \frac{x students}{100 percent}

This will allow you to find the total number of students at the school.

Cross multiplying and solving for x results in 300 total students.

Question 1:
45% had one or more absences. 45% of 300 students is 135 students.

Question 2:
As we found before, 11% of students had three or more. 11% of 300 is 33 students.

Can anyone help me please?
vovangra [49]

Answer:

- 6

Step-by-step explanation:

The given statement implies that the slope of line formed by (5, r) is (3, -2) is -2, as they lie on the same line.

Slope(using these pts) = (y2 - y1)/(x2 - x1)

=> - 2 = (-2 - r)/(3 - 5)

=> -2 = (-2 - r)/(-2)

=> (-2)(-2) = (-2 - r)

=> 4 = -2 - r

=> r = - 2 - 4

=> r = - 6
