tigry1 [53]

Answer:

(a) 83% of the scores were at or below her score.

(b) 17% was above her score.

Step-by-step explanation:

Given that:

Percentile score of Angela in the general aptitude test = 83rd percentile

To find:

a) Percentage of scores which were at or below her score?

b) Percentage of score which were above her score?

Solution:

First of all, let us learn about the term "<em>Percentile</em>"

Percentile is the value below which the certain percent of people/marks fall.

Therefore, when we say percentile of someone's score is x, then there are x\% of scores are at the same level or below.

And (100-x)\% of the scores are above this level.

Therefore, we can say that:

83% of the scores were at the same level or below the score of Angela.

And (100-83)\% = 17\% of the scores were above the score of Angela.

Solve the equation -6 + 3x = -9
sammy [17]

First you had to add by six from both sides of equation form.

-6+3x+6=-9+6

Then simplify.

3x=-3

Next you divide by three from both sides of equation form.

\frac{3x}{3}= \frac{-3}{3}

Finally simplify by equation.

\frac{-3}{3}=-1

x=-1

Final answer \boxed{x=-1}

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.
