Angela took a general aptitude test and scored in the 83rd percentile for aptitude in accounting.
1 answer:
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 , 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.

Answer:
x-intercept = 10
y-intercept = -8
Step-by-step explanation:
To identify the y-intercept, we will need to format the equation in the form . We can start by subtracting
from both sides of the equation:
Divide both sides of the equation by the coefficient of , which is
:
The is representative of the y-intercept in
.
Identify in the equation
:
Therefore, our y-intercept is -8.
To solve for the x-intercept, replace the in the equation
with a zero:
Add to both sides of the equation:
You can go ahead and divide by
to get rid of the fraction:
Divide both sides of the equation by the coefficient of , which is
:
Therefore, our x-intercept is 10.
Answer:
3) ,
Step-by-step explanation:
Given that the explicit rule for a sequence is .
Now we need to find about what is the recursive rule for the sequence and match with the given choices to find the correct choice.
1) ,
2) ,
3) ,
4) ,
Plug n=1 into given formula to get first term
base of the exponent part is (-2) so that means we need to multiply -2 to the previous term to get nth term
Hence correct choice is: 3) ,
