Answer:
1.68 pints
Step-by-step explanation:
First you need to determine how much blue paint she used, then you can determine how much white paint she used. :)
4/5 of 8.4:
4/5 * 8.4 = 6.72 pints
Now we can determine how many pints of white paint she used by subtracting 6.72 from 8.4:
8.4 - 6.72 = 1.68
So she used 1.68 pints of white paint. :) Hope this helped!
It is d. Expression has to have an equal sign and solves for a variable in this case it's a
The answer is B (100 times).
Answer:
0.7407 = 74.07% probability that the customer is a new customer.
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
In which
P(B|A) is the probability of event B happening, given that A happened.
is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Pays by credit card
Event B: New customer.
Probability of a customer paying by credit card:
50% of 80%(new customers).
70% of 20%(regular customers). So
Probability of a customer paying by credit card and being a new customer:
50% of 80%, so:
What is the probability that the customer is a new customer?
0.7407 = 74.07% probability that the customer is a new customer.
