Answer:
Please see the attached image.
Step-by-step explanation:
I'm assuming you've already learnt how to draw an equation in slope intercept form. The line of an inequality is drawn the same way.
The difference is that for inequalities you will have to shade.
Basically, the inequality sign will tell you which are to shade.
Greater than will mean above the line and
Less than will be below the line.
Also, if the sign is a "or equal to" sign, then the line will be solid, if not, it's dotted.
Answer:
So then we have approximately 14% of the values higher than 95.5
Step-by-step explanation:
For this case we assume that the info is given on the figure attached.
From this figure we have the following frequencies for each class
Class Frequency
___________________________
70.5-75.5 13
75.5-80.5 7
80.5-85.5 6
85.5-90.5 10
90.5-95.5 19
95.5-100.5 9
____________________________
Total 64
So we have a total of 64 values and we want to find the percentage of students that scored higher than 95.5 so we can use the formula of relative change and we got:
So then we have approximately 14% of the values higher than 95.5
