Answer:

x=10

Step-by-step explanation:

So, we got our equation:

\frac{x+4}{2}=y

We'll multiply both sides by 2 to get rid of that fraction.

x+4=14

Then, we just subtract 4 from both sides.

x=10

Fynjy0 [20]

Answer:

0.0064 is the probability that Isaac will find his first defective can among the first 50 cans.    

Step-by-step explanation:

W are given the following in the question:

Probability of defective can =

P(A) = \dfrac{1}{90}

We have to find the probability that Isaac will find his first defective can among the first 50 cans.

Then the number of adults follows a geometric distribution, where the probability of success on each trial is p, then the probability that the kth trial (out of k trials) is the first success is

P(X=k) = (1-p)^{k-1}p

We have to evaluate:

P(x = 50)\\= (1-\frac{1}{90})^{50-1}(\frac{1}{90})\\= 0.0064

0.0064 is the probability that Isaac will find his first defective can among the first 50 cans.
