Answer:
Pretty sure it's C
Step-by-step explanation:
For inverse functions, I do the opposite operation
the only logical inverse function I see working in this expression would be C
divide the 5 from 5x and add the 3
Also, subtract the f(x) on both sides to get the "- y"
so, you get : 5/x + 3 = - y (f(x) is just "y")
(a) From the histogram, you can see that there are 2 students with scores between 50 and 60; 3 between 60 and 70; 7 between 70 and 80; 9 between 80 and 90; and 1 between 90 and 100. So there are a total of 2 + 3 + 7 + 9 + 1 = 22 students.
(b) This is entirely up to whoever constructed the histogram to begin with... It's ambiguous as to which of the groups contains students with a score of exactly 60 - are they placed in the 50-60 group, or in the 60-70 group?
On the other hand, if a student gets a score of 100, then they would certainly be put in the 90-100 group. So for the sake of consistency, you should probably assume that the groups are assigned as follows:
50 ≤ score ≤ 60 ==> 50-60
60 < score ≤ 70 ==> 60-70
70 < score ≤ 80 ==> 70-80
80 < score ≤ 90 ==> 80-90
90 < score ≤ 100 ==> 90-100
Then a student who scored a 60 should be added to the 50-60 category.
Answer:
4% Hope this helped.
Step-by-step explanation:
The formula is: final value minus starting value divided by the starting value then times 100
THIS FORMULA ONLY APPLIES TO PERCENT INCREASE
<u>Final Value−Starting Value</u>
Starting Value x100
Plug numbers in
2600-2500/2500 x 100
100/2500=0.04
0.04x100
=4%
Answer:
To use division to find the decimal equivalent of a rational number, divide the top number by the bottom number. You will get a decimal number.
