Answer:
12 days.
Step-by-step explanation:
I looked at it this way:
He has to take 4/28 pills the first day, so it's 28-4=24. Then I divided 24 by 2.
In simpler terms:
28-4=24
24/2
12
Answer:
5,250
Step-by-step explanation:
15 x 35 = 525
525 x 10 = 5250
$96.00 because if you want to find his hourly wage all you have to do is divide by 5. And his hourly wage is $12.multiply that by 8 and you have $96.00
Using the binomial distribution, it is found that there is a 0.0231 = 2.31% probability that the first person to say yes will occur with the seventh customer.
For each person, there are only two possible outcomes, either they say yes, or they say no. The probability of a person saying yes is independent of any other person, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- The probability that the seventh person is the first to say yes is P(X = 0) when n = 6(first six say no) multiplied by 0.37(probability the seventh say yes).
- 37% say yes, hence
Then:
0.0231 = 2.31% probability that the first person to say yes will occur with the seventh customer.

First set up the ratio 2/5 = 10/x where <em>x</em> is the number of girls.
Now, we can use cross-products to find the missing value.
So we have (2)(x) = (5)(10).
Simplifying, we have 2x = 50.
Dividing both sides by 2, we find that x = 25.
So there are 25 girls in the class if there are 10 boys.
