First, we always have to list them from least to greatest: 3,7,10,11,12,14,15,17,17,21.
A. I attached an image of the cumulative frequency table.
B. I wasn't able to make a histogram since I can't find any templates or programs to create it on.
Part C:
Mean: 12.7
Median: 26/2=13
Mode: 17
Range: 21 -3 = 18
Part D:
Minimum: 3
First Quartile: 10
Third Quartile: 17
Maximum: 21
E. I can't a program again, but I can help you over a call if you'd wish.
Part F:
40th Percentile: 0.31
V=B+15
V+2B=180
Therefore:
3B+15=180
B=55
V=70
Check:
V+2B=180
70+2(55)=180
70+110=180
180=180. Checks.

Answer:
12 Pieces
Step-by-step explanation:
Number of candies in Jane's bag = x
she gives 8 to her friend;
x - 8
Then jane's grandmother buys 5 more pieces than jane had originally; add (x + 5)
x - 8 + x + 5
Now jane has 27 pieces of candy
x - 8 + x + 5 = 27
Solve for x;
x - 8 + x + 5 = 27
2x - 3 = 27
2x = 27 -3
2x = 24
x = 12
The answer is: " 27 " .
__________________________________________
3⁵ / 3² = 3⁽⁵⁻²⁾ = 3³ = 3 * 3 * 3 = 9 * 3 = 27 .

-Edit -- Note the following property of exponents : "quotient rule" of exponents:
_____________________________________________
Given that "a" and "b" are positive integers; and that "x" is a real number greater than "zero";
____________________________________________
If a <span>≥ b , then:
x</span>ᵃ /xᵇ = x⁽ᵃ ⁻ ᵇ⁾ ;
____________________________________________
If a <span>< b , then:
</span>
xᵃ /xᵇ = x⁽ᵇ ⁻ ᵃ⁾
