Using the Empirical Rule, it is found that there is a 68% probability that a student scored between 66 and 82.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, considering the mean of 74 and the standard deviation of 8, we have that:
74 - 8 = 66
74 + 8 = 82.
Hence, there is a 68% probability that a student scored between 66 and 82.

Here is your answer:
Find the tenth place value which is two:
74.326
Then look to the next number and see if that number is greater or equal too 5:
Now if 6 is greater than 5 you have to round up one so 2 would be 3:
74.330
Therefore the answer is "74.330."

We have two classrooms and seven packages.
This means we need to divide the seven packages in half (two pieces).
7packages ÷ 2 classrooms = 7/2 = 3.5 packages per class
(three and a half packages)
Answer:
8× 12= 96 hope it helps!!
Answer:
A B C D is similar to F G H E
Step-by-step explanation:
Here we can see that
A= F= 110 degrees
B = G= 70 degrees
C= H = 110 degrees
D= E = 70 degrees
Therefore
A B C D is similar to F G H E
so the option 3rd correct.
