Answer:
The largest standard deviation for the amount of cereal in a box is 0.3906.
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:
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:
The z-score of X = 16 has a pvalue of 0.1. So it is . Now we have to find the value of .
The largest standard deviation for the amount of cereal in a box is 0.3906.
Answer:
120 Vials
Step-by-step explanation:
160/1and1/3
160/4over3
Multiply top by 3
480/4
120
To convert a decimal to a percent, multiply the decimal by 100, then add on the % symbol. An easy way to multiply a decimal by 100 is to move the decimal point two places to the right.
Y=mx+b
4y=5x-12
y=5/4x-3
so you change your y intercept (-3) to your other y intercept (15)
y=5/4x+15
