Answer:
The answer would be the second plot
Step-by-step explanation:
The frequency table show how many sick patients there are in a single age range. In the first two plots, the total dots between numbers 24, 25, 26, 27, 28, and 29 add up to 3, and the other 2 plots do not, so those are not correct.
When we add up the total of dots from ages 30-34 on the first plot, there are only 4 sick patients. On the second graph, there are 6 total patients in that age range. Therefore, the dot plot that corresponds with the frequency table is the second one.
It will be 600in or 150cm.
Reason is perimeter is just adding up the sides so if you wanna find it in inches then you multiply 4 by each side and if it’s just cm then just add them all up
I don't think so. 1/4 and 8/36. 1 times 8 is 8 but 4 times eight is 32 so it would be 8/32.
I DONT REMEMBER BUT IM PRETTY SURE ITS 2
Answer:
B. 0.0918
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:
What proportion of batteries would be expected to last less than 16 hours?
This is the pvalue of Z when X = 16. So:
has a pvalue of 0.0918.
So the correct answer is:
B. 0.0918
