Angela took a general aptitude test and scored in the 83rd percentile for aptitude in accounting. (a) What percentage of the scores were at or below her score?
(b) What percentage was above her score?

(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 "Percentile"

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

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

And 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 of the scores were above the score of Angela.

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

option 2 is correct.

step-by-step explanation:

we are given two inequality equation

x+y> 5 and -3x+2y< -2

first we draw the graph of both function using t-table method

equation: x+y> 5

for x=0, y=5

for x=-5, y=0

table:

x   :   0     5

y   :   5     0

test point (0,0) , 0> 5

false

equation: -3x+2y< -2

for x=0, y=-1

for x=2, y=4

table:

x   :   0     2

y   : -1       4

test point (0,0) , 0< -2

true

now we draw the graph. see the attachment for graph.

common region would be solution set.

option 2 is correct.
