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
The average value is given by

Answer:
The cook made 7 pints
Step-by-step explanation:
Just minus the half pints
Just do for example on number 38 you will do 6.8/1000= 0.0068 which is the answer
Answer:
7.5 quarts of olive oil remain.
Explanation:
Let
q = quarts of olive oil remain
<span>25%</span> of olive oil remains means that <span>75%</span> has been used.
22<span>12</span> quarts = 22.5 quarts used
<span><span>22.5.75</span>=<span>q.25</span></span>
Multiply both sides by .25 to isolate q.
<span><span>22.5.75</span><span>(.25)</span>=<span>q.25</span><span>(.25)</span></span>
<span><span>5.625.75</span>=q</span>
<span>7.5=<span>q</span></span>
