Step-by-step explanation:
Given the expression that Tayler tried to evaluate as:
We will solve this equation using PEDMAS
Multiplication before addition and subtraction
On solving:
From the steps above, we can see that Tayler made an error in step 3 by taking the difference of 7 and 6 and arriving at 1 instead of summing up to get 13 as shown above.
Answer: Divide 500 by 3.49. Or 3.50 if you're rounding

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
