Answer: Mean = 5.25
Variance = 1.3125
Standard deviation = 1.456
Step-by-step explanation:
The mean and variance of a binomial distribution with parameters n (number of trials) and p ( the probability of getting success in each trial) is given by :-

Given : The total number of enter a clothing store : n=7
The probability of a customer making a purchase= 0.75
Now,

Answer:
72
Step-by-step explanation:
I have a weird way of doing it
so if 18 is 25%
18+18=36
then 36 would be 50%
36+36=72
so then 72 would be 100%
72*.25=18
Answer: $360
Step-by-step explanation:
In one hour, she makes $9 * 10 dogs = $90.
In 4 hours, we simply multiply that by 4 to get $90 * 4 = $360 total
Answer:
25 grams of protein
Step-by-step explanation:
10 grams of protein is in 1 cup of milk.
To understand how many grams of protein are in 0.5 cups of milk, I would need to divide 10 by 2, to get 5.
There are 5 grams of protein in 0.5 cups of milk.
Now if I want to see how many grams of protein are in 2 cups of milk, I would multiply 10 by 2, to get 20.
There are 20 grams of protein in 2 cups of milk.
But, the question is asking for how much protein is in 2.5 cups of milk.
Since we know how much is in 2 cups, and 0.5, we can just add them together, because 2+0.5 is 2.5.
20+5 is 25 grams.
There are 25 grams of protein in 2.5 cups of milk.

<h3>Further explanation</h3>
We will calculate the unit conversion factor used to convert its engine displacement from cubic-centimeters to cubic-inches.
The relationships between inch and cm are as follows:

Inches and cm represent units of length.
Made into fractions, 1 inch as the denominator and 2.54 cm as the numerator.

As a unit conversion factor of volume, the numerator and the denominator in cubic.


Thus, we get the unit conversion factor

Let's use this unit conversion factor to calculate its engine displacement in new units.

Note for cm³ units that have been crossed out.
The conversion result is
