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:
Natalie arrived at 3:55 pm or 15:25
Step-by-step explanation:
Start time is 3:00
The first two friends arrived at 10 minutes after 3. Arrival time = 3:10
Natalie arrived 45 minutes later. Arrival time is 3:10 + 45 = 3:55
Natalie arrived at 3:55, using 24-hour formats, the arrival time is 15:55
Proportion
(750/35)=(1000/x)
35000=750x
x= (35000/750)
x=46.67 minutes
Answer:
A is correct
Step-by-step explanation:
Midpoint Formula
((x1 + x2)/2,(y1+y2)/2)
so , A(3,5) and B(2,2)
x1 = 3
x2 = 2
y1 = 5
y2 = 2
put the values in midpoint formula
((3+2)/2 , (5+2)/2)
(5/2, 7/2)
