a binomial event has n=20 trials. the probability of success for each trial is 0.20. let x be the number of successes of the event during the 20 trials. what is the probability that x is at least 12?

a 0.0001017
b 0.9998983
c 0.848
d 0.152

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.

yeah i know the problem you need. i am taking it right now. the answer is step 3
