Answer:
The probability of the randomly selected student being a graduate is 24%.
Step-by-step explanation:
From the charts we can see that there <u>8120 students that are Undergraduates</u> and <u>2610 students that are Graduates</u>. We add this up to get the <u>total number of students in the University 10730</u>. This Gives us the following fraction of Graduates in the University.
...we multiply by 100 to turn the decimal into a percent
We can then round to the nearest percentage which is 24%.
So the probability of the randomly selected student being a graduate is 24%.

Answer:
Step-by-step explanation:
What we would normally do when factoring a polynomial is find the greatest factor, but in this case, there is none. What we do then is multiply the coefficient of the first term by the last term.
So in this case, that expression would be...
Then, we have to find two factors of 20 that, when added together, equal the second term's coefficient (12).
These factors would be 2 and 10.
We then replace the second term in the polynomial with . This ends up looking like this:
<em>Keep in mind that this did not change the value of the polynomial, as 10x + 2x still equals 12x.</em>
This new expression lets us use a technique called group factoring. To start group factoring, we need to take out the greatest common factor (GCF) of the first two terms. That ends up looking like this:
Then, we do the same thing with the last two terms.
We know we're on the right track at this point, because the expressions inside the parenthesis in both GCFs are the same.
The last step is combining the terms on the outside of the parenthesis, and multiplying it with what's inside the parenthesis. The final answer looks like this.
Answer:
Step-by-step explanation:
We can write our unknown number like x
four less than the quotient of a number cubed and seven, increased by three
five times the difference of a number squared and six
nine more than the quotient of six and a number cubed, decreased by four
twice the difference of nine and a number squared
