Ok, so we see the sides are congruent
we know that therfor the angles oposite those sites are congruent
therfor 2x=y-12

also
all angles add to 180
2x+y-12+40=180
2x=y-12 so
2x+2x+40=180
4x+40=180
minus 40 both sides
4x=140
divide both sides by 4
x=35


sub back

2x=y-12
2(35)=y-12
70=y-12
add 12
82=y




x=35
y=82

Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to fi
Keith_Richards [23]

Answer:

P(X = 12) = 0.0064.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

In this problem we have that:

n = 30, p = 0.2

We want P(X = 12). So

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 12) = C_{30,12}.(0.2)^{12}.(0.8)^{18} = 0.0064

P(X = 12) = 0.0064.
