The answer should be 7(x+8)
Answer:
93% probability of a student taking a calculus class or a statistics class
Step-by-step explanation:
We solve this problem building the Venn's diagram of these probabilities.
I am going to say that:
A is the probability that a student takes a calculus class.
B is the probability that a student takes a statistics class.
We have that:

In which a is the probability that a student takes calculus but not statistics and
is the probability that a student takes both these classes.
By the same logic, we have that:

The probability of taking a calculus class and a statistics class is 0.07
This means that 
The probability of taking a statistics class is 0.90
This means that
. So



The probability of a student taking a calculus class is 0.10
This means that 



What is the probability of a student taking a calculus class or a statistics class

93% probability of a student taking a calculus class or a statistics class
Answer:
=45x√5x
Step-by-step explanation:
The provided expression is: 3√5x×3√25x²
We can simplify 3√25x² because √25x²=5x
3×5x=15x
Combine with the rest of the expression through multiplication.
3√5x×15x
=45x√5x
The expression 3√5x×3√25x² is equivalent to 45x√5x.
The expected simplified answer is 45x√5x
