For fraction notation it would be 2/10
and for the percent notation it would be 20%
if you need any explanation ask me
hope this helps!
For this, we are just going to plug in -9 for every x and then solve the equation:




Now we know that q(-9) is equal to 566.
The answer is going to be 14.125 in decimal form
Answer:
.9 or 90%
.1 or 10%
Step-by-step explanation:
E= Exam
P=Paper
E= .71
P= .45
E∩P=.26
A.) E∪P=?
E∪P= E+P-E∩P
.71+.45-.26= .9
B.) E'∩P' = (E∪P)'
(E∪P)' = 1-.9 = .1
