Answer:
D. -1.75°C
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
Assume that the mean reading is 0degrees°C and the standard deviation of the readings is 1.00degrees°C. This means that
.
Find the temperature reading that separates the bottom 4% from the others.
The bottom 4% if the 4th percentile.
This is the value of X when Z has a pvalue of 0.04. This is
.
![Z = \frac{X - \mu}{\sigma}](https://tex.z-dn.net/?f=Z%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Csigma%7D)
![-1.75 = \frac{X - 0}{1}](https://tex.z-dn.net/?f=-1.75%20%3D%20%5Cfrac%7BX%20-%200%7D%7B1%7D)
![X = -1.75](https://tex.z-dn.net/?f=X%20%3D%20-1.75)
The correct answer is:
D. -1.75°C

Step-by-step explanation:
First, we find the price of the turkey by multiplying the weight of turkey by the price per pound.
2.1 pounds of turkey at the deli. The price of the turkey was 2.87 per pound.
2.1 lb * 2.87 $/lb = $6.03
Then, we find the price of the ham by multiplying the weight of ham by the price per pound.
She also bought 4.8 pounds of ham. The price of the ham was 2.11 per pound.
4.8 lb * 2.11 $/lb = $10.13
Now we add the two prices together.
$6.03 + $10.13 = $16.16
The total price was $16.16
45/144 we simplify with 3
15/48 again with 3
5/16
we cam't simplify anymore, because 5 is a prime number. so that's the simplest form
