38° +90°+x = 180° ( Angles on a straight line)
x+ 128° =180°
x= 180° -128°
x= 52°
$3 for 25 minutes, 3 divided by 25
3 : 25 = 0.12 : 1
Therefore, you get paid $0.12 per minute
Answer:
YES
Step-by-step explanation:
Yes, the probability can be found through the binomial probability formula.
Binomial probability is used when there are two possible outcomes. The success (p) and failure (q) must be clear. Here, in the question if we need to find out the probability if live entertainment had increased the amount of money spent, then the percentage increase will be considered as success.
While if we want the probability that there is no change in the percentage of money spent, then it will be considered as failure.
