21 22 23 24 TIME 25 A large hotel has five elevators. On any given day, there is an 8% chance that one elevator is broken The ele operate independently of one another. The Robertsons are staying in this hotel for five days. Let X represent number of days one elevator is broken during their stay. What are the mean and standard deviation of X? x=0.4,0 = 0.074 O x = 0.4.0,=0.61 x = 2.5, 0, = 1.92 Owx = 4.0,= 0.89 ​

step-by-step explanation:

step-by-step explanation:

i believe its "c" because all of the other options include a but it could be d because there is a way of financing with cash at certain places but its uncommon.

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
