Required

From the attachment, we have:

---- the sample size
Next, we list out all outcomes more than or equal to 5.
i.e.

5 is represented with the vertical blue rectangle (with frequency 21).
So, the other elements are to the right of frequency 21.
So, we have:


The probability is then calculated as:

This gives


Answer:
The answer is A
Step-by-step explanation:
By looking at the graph, the y-intercept is -1. So, the answer must be A or C.
Then we can look at the the graph, you can see the line is left up right down. So the equation will be negative, which is A.
Step-by-step explanation:
-3+2y<4x
then
2y< 4x+ 3 (add both sides with 3)
y < 2x +3/2 ( divide both sides by 2 that is positif and we do not change the sens < )
Hope you understand.
Answer:
$12500
Step-by-step explanation:
Given that:
Salary plan 1:
