The stem-and-leaf plot lists the scores earned by students on a math test.
how many students earned a score of 90 or greater?
enter your answer in the box.

There are 6 students earned a score of 90 or greater.

Step-by-step explanation:

From the given stem-leaf table, we can list down the numbers greater than or equal to 90.

Look at the stem 9 and following leaf numbers

91, 91, 91, 94, 95, 95

There are 6 students earned a score of 90 or greater.

Hope this will helpful.

Thank you.

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
