Given the following cumulative frequency table, what is the mean of the distribution?

value (x) cumulative frequency
1 0.15
3 0.45
5 0.60
7 0.85
9 1.00

a-μx = 19.45
b-μx = 4.9
c-μx = 4.5
d-μx = 3.89

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
