Answer:
There is no next step, the problem is answered!
Step-by-step explanation:
49x^2 = 36
take square roots of both sides:-
7x = +/- 6
x = 6/7, -6/7.
Answer:
So, the probability is P=0.041.
Step-by-step explanation:
We know that 45% of people in Fast-Food restaurants order a diet drink with their lunch.
We conclude that the probaility p=0.45 that a person order a diet drink.
We calculate the probability that the fourth person orders a diet drink.
We get:
So, the probability is P=0.041.
55% of 40 is 22
(0.55)*(40) = 22
