You would take x^2-4x+3x-2=28 
add common numbers x^2-x-2=28
set it equal to 0  x^2-x-30
use the quadratic formula x=1+-√1-4(1)(-30)÷2
Solve for x 1+-√131÷2
X÷≈6.223 
plug x into both equations for kl and jl and you will get lenghts that are ≈13.829 for Jk and ≈16.669 for KL

A poll reported that 66 percent of adults were satisfied woth the job the major airlines were doing. Suppose 25 adults are selec
777dan777 [17]

Answer:

A)Option D

B)P(X = 15) = 0.1325

Step-by-step explanation:

A) From the question, the information given follows binomial distribution because there are two mutually exclusive outcomes for each​ trial, there is a fixed number of trials. The outcome of one trial does not affect the outcome of ​another, and the probability of success is the same for each trial.

So option D is correct.

B) From the question, we are told that the poll reported that 66 percent of adults were satisfied with the job. Thus, probability is; p = 0.66

Let X be the number of adults satisfied with the job. Since 25 are selected,

Thus;

P(X = 15) = C(25, 15) * (0.66)^(15) * (1 - 0.66)^(25 - 15)

P(X = 15) = 3268760 × 0.00196407937 × 0.00002064378

P(X = 15) = 0.1325
