Answer:
11.7
Step-by-step explanation:
Step 1: Our output value 39.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 39 = 100%.
Step 4: Similarly, x = 30%.
Step 5: This results in a pair of simple equations:
39 = 100%(1)
x = 30%(2)
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
39/x = 100%/30%
Step 7: Again, the reciprocal of both sides gives
x/39 = 30/100
------> x = 11.7
Therefore, 30% of 39 is 11.7

Answer:
9/25
Step-by-step explanation:
In this case, 0.36 has two numbers after the decimal, so, we place 100 in the denominator and remove the decimal point.
⇒ 36/100
After reducing this fraction we get
⇒ (36 ÷ 4) / (100 ÷ 4) = 9/25

Answers
Answer:
I'm guessing frequency means deposits,
a. 13
b. $50
c. not sure what this means (sorry!)
d. $2,535
Step-by-step explanation:
Can I have brainliest? It would help me out, if not thanks anyways! Hope this helped and have a nice day!
Part A
Answer: 13-------------
Explanation:
Add up all the values in the frequency column. This is because everything in the table represents a deposit of some kind.
3+1+5+2+2 = 13
========================================================
Part B
Answer: $50-------------
Explanation:
Simply list the value that has the highest frequency. This is the mode. It's possible to have more than one mode, and it's also possible to not have any mode at all.
========================================================
Part C
Answer: Median-------------
Explanation:
Let's list out all of the deposits. The repeats aren't typos. The deposits are
125, 125, 125, 300, 50, 50, 50, 50, 50, 205, 205, 100, 100
They sort to
50, 50, 50, 50, 50, 100, 100, 125, 125, 125, 205, 205, 300
Since we have n = 13 items here, the halfway point is n/2 = 13/2 = 6.5 which rounds to 7. The median is in slot 7. We have 6 items below the median and 6 items above the median (giving 6+1+6 = 13 total).
The value in slot 7 is 100, which shows us that 100 is the median.
========================================================
Part D
Answer: $2535-------------
Explanation:
Form a third column of values where we multiply each deposit by the corresponding frequency. Check out the table below.
After this third column is formed, add up those values to get the total amount of deposits. Spreadsheet software can make quick work of something like this. I used OpenOffice spreadsheet which is free software.
You should find that 1535 is the total amount deposited. This value is then added onto the $1000 already in there to get 1000+1535 = 2535
