- 10 completed only elementary school;
- 10 completed elementary school and high school;
- 7 completed elementary school, high school and college;
- 3 completed elementary school, high school, college and graduate school.
You can fill these numbers into the table:
The cumulative percentage of fathers who completed only elementary school is nearle 33%.
Answer:

Step-by-step explanation:
The given complex number is:

Firstly we can solve (2+3i)(4-7i)(1+i)
= 2(8)+2(-7i)+4(3i)+3i(-7i²)× (1+i)
= (16-14i+12i-21i²i)× (1+i)
Since, i² = -1
= (16-14i+12i-21(-1)i)× (1+i)
= (16-14i+12i+21)× (1+i)
= (29-2i)(1+i)
= 31+27i
Denominator : (1-i²)
= (1-(-1))
= 2

Hence, the correct answer is
.
First, you have to establish the fact that there is a correlation because the points are obviously grouped together
The, you have to know that which direction a positive and negative gradient face ( a positive gradient looks like a tick when you join a line to it)
Look at the attachment and the answer is a negative correlation ;)
So x is from -3 to 10, including -3, but not including 10
so that would be the interval
[-3,10)
remember, the brackets [] are inclusive meaning ≤ and ≥
parenthasees () are not inclusive maning < and >
[-3,10)
