What is true about this linear inequality <br> y&gt;3/4-2
astraxan [27]

Inequalities help us to compare two unequal expressions. The statements that are correct are B, D, and E.

<h3>What are inequalities?</h3>

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

The complete question is:

Which statements are true about the linear inequality y >3/4 x – 2? Check all that apply.

-The slope of the line is –2.

-The graph of y >3/4 x – 2 is a dashed line.

-The area below the line is shaded.

-One solution to the inequality is (0, 0).

-The graph intercepts the y-axis at (0, –2)

-The slope of the line is 3/4. Thus, the first statement is false.

-The graph of y >3/4 x – 2 is a dashed line. The given statement is true.

-The area below the line is shaded. The statement is false.

-One solution to the inequality is (0, 0). The given statement is true.

-The graph intercepts the y-axis at (0, –2) The statement is true.

Hence, the statements that are correct are B, D, and E.

THE AP CALCULUS EXAM SCORES WERE RELEASED IN JULY. THE SECONDARY MATH SPECIALIST PREPARED THE BOX PLOT SHOWN TO PRESENT THE SCOR
Ganezh [65]

Answer : option A

To find the range of scores that represents the middle 50 % of the student who took the test , we find inter quartile

Inter quartile range is the middle 50% of the given range of scores.

The difference between the upper quartile and lower quartile is the inter quartile that is middle 50%

From the diagram , we can see that

Upper quartile = 89

lower quartile = 65

So range is 65%  to 89%
