Answer:
The correct option is;
c. Her score was better than those of 60% of all test takers
Step-by-step explanation:
Percentile Score is the score of an exam or test candidate with regard to the relative performance of the other persons that took part in the exam or test.
The percentile score is calculated by converting candidates scores into a scale consisting of the scores of all candidates and ranging from 0 to 100
A 60th percentile score means that the student performed better than 60% of all the candidates of the test and 40% of the test takers scored the same as or better than the student.
You don't need me to give you all six of them, because they're
all essentially the same problem. So I'll give you two, and lead
you close to the answer of another one, and by then, you should
be able to handle them on your own.
5). y/2 > 0 .
What can you do to the left side to get 'y' all alone ?
Multiply the left side by 2 .
But you always have to do the same thing to both sides.
Multiply each side by 2: y > 0 .
_____________________________
6). -4 < r/5
What can you do to the right side to get 'r' all alone ?
Multiply the right side by 5 .
But you always have to do the same thing to both sides.
Multiply each side by 5: -20 < r
_______________________________
7). 5c < 10
What can you do to the left side to get 'c' all alone ?
Divide the left side by 5 .
But you always have to do the same thing to both sides.
Divide each side by 5: c < ____
Over to you, champ !
First of first we are going to solve the term inside the parenthesis in the right side of the equation .
30 + 6p = 7 ( p+6 ) - 5
30 + 6p = 7p + 42 - 5
Then , isolate the terms with variable to the left side of the equation and the constants to the right side of the equation .
30 + 6p = 7p + 42 - 5
6p - 7p = 42 - 5 - 30
- Combine the terms and solve for the variable p.
6p - 7p = 42 - 5 - 30
- 1p = 7
- 1p = 7
P = - 7
Therefore , the value of the variable p is - 7
Is this for edgenuity? :/ cuz i have a teacher login.
V = 4/3 (pi) r^3
ball with radius of 18 cm...
V = 4/3(3.14)(18^3)
V = 4/3(3.14)(5832)
V = 24429.02
ball with radius of 12...
V = 4/3(3.14)(12^3)
V = 4/3(3.14)(1728)
V = 7238.23
24429.02 - 7238.23 = 17190.79 greater <====
