Answer:
0.5962
Step-by-step explanation:
Given that :
p = 61% = 0.61
q = 1 - p = 1 - 0.61 = 0.39
n = 154 ; x = 93
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x>=93) = p(x=93)+p(x=94)+...+p(x=n)
P(x>= 93) = 0.59619
P(x>= 93) = 0.5962
13.5/3 = 4.5

Answer:
20
Step-by-step explanation:
sin(28) sin(x)
---------- = -----------
7 5
sin(28)* 5 = 7sin(x)
---------------------------
7
sin(28) * 5
---------------- = sin(x)
7
You have to seperate sin from (x). When you do that, it becomes inverse (sin^-1).
sin(28) * 5
sin^-1 (------------------) = x
7
Imput that into you calculator, and you should get 19.59302173 (20 to the nearest degree)
Hope this helps.
