Answer:
21.19% eat less than 10 pieces of candy on halloween
Step-by-step explanation:
Problems of normally distributed samples are 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 percentage eat less than 10 pieces of candy on halloween
This is the pvalue of Z when X = 10.
has a pvalue of 0.2119
21.19% eat less than 10 pieces of candy on halloween
Answer:
it's d
Step-by-step explanation:
shaded circle means that number and up or down
ansd unshaded means up or down.
-3 is shaded so it includes -3 and below
while 1 isnt so it has to be below 1
I had gotten -3y=x+5 its parallel to 3y=-x+5 but its not through (0,-3)
For example: 3-4d=13.
add 3 to both sides.
now you should have 4d=16
divide by 4 on both sides
your answer would be d=4
Answer:
hi! your answer should be 60% off of any item.
