Here are two different samples drawn from two different populations: 000
Sample A
HHH
(n=11)
Sample B
(n=14)
0
50
100
Which sample satisfies the normal condition for constructing a t interval?

Prove that (x-2)is factor of p (x)=2x³-3x²-17x+30

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.

Solve for the equation. 4x - 13 = 2x + 9
