Answer:
The answer is
her score was in the top 85% of all test takers' scores.
Step-by-step explanation:
Percentile is the relative standing in a set of data from the lowest values to highest values.
If your score is in the 85th percentile, it means that 85% of the scores are below your score and 15% are above your score.
Answer:
D. Use the Distributive Property. You clear the parentheses and then solve the two-step equation.
Step-by-step explanation:
Given problem;
2(w − 3) = 5
To solve this problem:
Use the distributive property to clear the parentheses;
2w - 6 = 5
Then, collect like terms, add 6 to both sides;
2w = 5 + 6
2w = 11
Now divide both terms by 2
w = 
Answer:
Step-by-step explanation:
volume=1/3×πr²h
=1/3π×(11.2/2)²×5.9
=1/3×22/7×(5.6)²×5.9
≈1/3×22×5.6×8×5.9
≈1938.3 in³
Answer:
the probability is 0.24 or 24%
Step-by-step explanation:
Given
Percentage of time he goes out with his girlfriend = 40%
Percentage of time he goes out to a bar = 60%
If he goes out with his girlfriend, the percentage of times he spends the night at his girlfriend’s apartment = 30%
If he goes out to a bar, percentage of times he gets in a fight and gets thrown in jail = 40%
let probability that the roommate went to the bar = A
As the roommate going to jail is a conditional probability dependent on A happening, the true probability of the roommate is found by multiplying the absolute probability of the roommate going out to a bar (A) by the probability of the roommate going to jail if he goes to a bar
that is Pr(B) =Pr (B n A)
Pr(B) = Pr(B/A) *Pr(A)
This is given as 60% * 40% or 0.6 * 0.4 (probabilities are 1/100 of percentages)
This gives an answer of 0.24 or 24%
In perspective this looks tricky but really its no ;) just follow it slowly.
110.25 is your total cost
3 is how many you bought.
So doing division 3/110.25= 36.75
CHECK: 36.75 + 36.75 + 36.75 = 110.25.
Hope this helps.
