What percent of 80 is 12? what number is 75% of 52?

HACTEHA [7]

Answer:

The answer for the first question is:

12/80 =

12 ÷ 80 =

0.15 =

0.15 × 100/100 =

0.15 × 100% =

(0.15 × 100)% =

Then, the answer for the second question is:

75% × 52 =

(75 ÷ 100) × 52 =

(75 × 52) ÷ 100 =

3,900 ÷ 100 =

When a trinomial is factored as (x + p)(x + q), what is the sum of p and q? A.The constant term of the trinomial B.The coefficie

Papessa [141]

It is B, the coefficient of the x-term. When you multiply this out, you get x*x+x*q+x*p+p*q, or x^2+x(p+q)+p*q
Notice how the x term is multiplied by p+q.

Hope this helps!

Three students were applying to the same graduate school. They came from schools with different grading systems. Student GPA Sch

stiv31 [10]

Answer:

Due to the higher Z-score, Kamala had the best GPA when compared to other students at her school.

Step-by-step explanation:

Z-score:

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

In this question:

Whichever student's GPA had the higher z-score had the best GPA compared to other students.

Thuy 2.5 3.2 0.8

This means that $X = 2.5, \mu = 3.2, \sigma = 0.8$
