Answer:
The unknown angle measures 56
Step-by-step explanation:
<u>Complementary Angles</u>:
Two angles are complementary when they add up to 90 degree.
An angle measure 34 less than a complementary angle. Which means angle one is 34 and angles two is 90 minus 34.
angle one + angle two = 90
34 + angle two = 90
angle two = 90 - 34
angle two = 56
A set of data has a normal distribution with a mean of 5.1 and a standard deviation of 0.9. Find the percent of data between 4.2 and 5.1.
Answer: The correct option is B) about 34%
Proof:
We have to find 
To find
, we need to use z score formula:
When x = 4.2, we have:


When x = 5.1, we have:


Therefore, we have to find 
Using the standard normal table, we have:
= 

or 34.13%
= 34% approximately
Therefore, the percent of data between 4.2 and 5.1 is about 34%
42.857 is the answer to 300÷ 7
