What percent of 80 is 12?<br><br>what number is 75% of 52? ​
HACTEHA [7]

Answer:

<em>The answer for the first question is: </em>

<em>12/80 =</em>

<em>12 ÷ 80 =</em>

<em>0.15 =</em>

<em>0.15 × 100/100 =</em>

<em>0.15 × 100% =</em>

<em>(0.15 × 100)% =</em>

<h2><em>15%</em></h2>

<em>Then, the answer for the second question is: </em>

<em>75% × 52 =</em>

<em>(75 ÷ 100) × 52 =</em>

<em>(75 × 52) ÷ 100 =</em>

<em>3,900 ÷ 100 =</em>

<h2><em>39 </em></h2>

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

The z-score is:

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

Z = \frac{2.5 - 3.2}{0.8}

Z = -0.875

Vichet 88 75 20

This means that X = 88, \mu = 75, \sigma = 20

The z-score is:

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

Z = \frac{88 - 75}{20}

Z = 0.65

Kamala 8.9 8 0.4

This means that X = 8.9, \mu = 8, \sigma = 0.4

The z-score is:

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

Z = \frac{8.9 - 8}{0.4}

Z = 2.25

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