the point that the function intercepts the x axis are the zeros of the function, where the products set equal to zero give you the x coordinate in which it intercepts.
x=-15 and x=9
set both equal to 0
x+15 and x-9
These are your two products
(x+15)(x-9)
or
x^2+6x-135
1. Answer:
30 is your frequency
Step-by-step explanation:
Frequency in this case would be the number of winners. So to find the frequency we would need to add up the total number of winners in the histogram.
So, 0 + 2 + 5 + 6 + 8 + 5 + 4 = 30
2. Answer:
6 (you already put that)
3.
The median can be found in the 50-59 bin or interval.
Answer: 12/4 or 3
Step-by-step explanation: Switch the numerator and denominator. This should leave you with the answer above.
Answer:
10 m
Step-by-step explanation:
A square has all equal side lengths. If that is the case, the we have 4 sides that equal each other:
x + x + x + x = 40 m
4x = 40m
x = 10m
So each side is 10 m long.
Okay so first of all you are going to cross multiply, which is simply multiplying diagonally across so (6x×5 and 25×3) then you just answer each part and set them equal to each other so (30x=75). Then you just divide 30 on each side which ends up being (x=2.5)
