Mean: Add all the numbers and divide by the amount of numbers.
20 + 0 + 7 + 10 + 11 + 0 + 25 + 15 + 1 = 89
89/9 = 9.889 (rounded)
Mean = 9.889 (rounded)
Median: Reorder from least to greatest, and the middle number is the median.
0, 0, 1, 7, 10, 11, 15, 20, 25
The middle number is 7
Median = 7
Mode: The number that shows up the most.
Mode = 0, which shows up one time more than all the other numbers
Range: Subtract the greatest number with least number
25 - 0 = 25
Range = 25

The formula to find slope it (y2-y1)/(x2-x1)
(2,4) is the first point
(6,2) is the second point
(2-4)/(6-2)
-2/4 which can be simplified to -1/2
Hope this helps
Answer:
The original price was 36.40
Step-by-step explanation:
p = original price of cake
using the coupon
p - 15% off = 30.94
p - .15 p = 30.94
Combine like terms
.85p = 30.94
divide each side by .85
p = 30.94/.85
p =36.40
The original price was 36.40
I can't see all ur work that u showed so far
Answer:
b = -4
Step-by-step explanation:
f(2) = R and f(-2) = R
Therefore f(2) = f(-2):-
(2)^3 + a(2)^2 + 2b + c = (-2)^3 +a(-2)^2 - 2b + c
8 + 4a + 2b+ c = -8 + 4a - 2b + c
The 4a and c cancel out. Then:-
8 + 2b = -8 - 2b
4b = -16
b = -4 answer
