The number of soda bottles Katie bought is 6
The given parameters are:
- Large Pizza = $14.99
- Soda = $1.50 per bottle
- Total cost = $23.99
Assume the number of soda bottle is x.
So, we have:
This gives
Subtract 14.99 from both sides of the equations
Divide both sides of the equations by 1.5
Rewrite the equation as
Hence, the number of bottles is 6

Divide by 3 each time
so
#1 is 9, because 27/3 = 9
#2 is 3, because 9/3 = 3
#3 is 1, because 3/3 = 1
So your answer is 9, 3, 1
hope this helps
Using the normal distribution, there is a 0.4826 = 48.26% probability that the sample mean is between 15 and 16 grams per day.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation .
For this problem, the parameters are given as follows:
The probability is the <u>p-value of Z when X = 16 subtracted by the p-value of Z when X = 15</u>, hence:
X = 16:
By the Central Limit Theorem
Z = 2.11
Z = 2.11 has a p-value of 0.9826.
X = 15:
Z = 0
Z = 0 has a p-value of 0.5.
0.9826 - 0.5 = 0.4826 = 48.26% probability that the sample mean is between 15 and 16 grams per day.

Answer:
136% = 1.36
Step-by-step explanation:
(950-700)/700
=0.3571 (0.36)
Then you have to plus one
0.36+1
=136% or 1.36
