Answer:
x = 3 and 7
There are two true solutions.
Step-by-step explanation:
To solve , use inverse operations by squaring both sides of the equal sign.
The quadratic expression can be factored into binomials and set equal to 0 by the zero product property to find x.
(x - 3) ( x - 7) = 0
x-3 = 0 so x=3
x-7 = 0 so x=7
Now check each solution into the original equation to be sure it solve the solution and is not extraneous.

Answer: Our required probability is 0.58.
Step-by-step explanation:
Since we have given that
Number of students worked in Nursing home = 11
Number of students worked in Tutoring center = 13
Number of students worked in Soup kitchen = 8
Number of students worked in Library = 18
Total number of students = 50
Since 3 students are selected from the club.
We need to find the probability that none of the three students volunteer at the soup kitchen.
So, Remaining students would be 50-8 = 42
So, probability that none of three students at the soup kitchen is given by
Hence, our required probability is 0.58.
