Answer:
7 pieces of homework
Step-by-step explanation:
This is an algebra problem. We first need to set up our algebra equation and we are going to find X (The amount of homework Richard submitted)
The algebra equation would be
X+X+2=12
*Combine like terms*
2X+2=12
Subtract 2 to both sides
2X=10
X=5
That means that Richard did 5 pieces of homework. We are not done yet because we want to find the amount of homework Isaac did. Earlier in the problem, it said that Issac did 2 more pieces of homework than Richard. Take Richard's number, 5 and add to 2 to it to get 7 pieces of homework.
Answer: Option 'a' is correct.
Step-by-step explanation:
Since we have given that
Total number of students = 200
Number of females = 110
Number of students under the age of 21 years of age = 125
Number of males under the age of 21 years or older = 45
So, it becomes
Males Females Total
21 years 45 80 125
21 years or older 45 30 75
Total 90 110 200
So, Probability that a female student age 21 or older is selected is given by

Hence, Option 'a' is correct.
