Answer:
B
Step-by-step explanation:
Yes, because the sample size is at least 30, and we have a random sample.
We have our sample size to be 33% of the student = 33 student (approx)
- According to conditions of normality which states that the sample size collected from a normally distributed population with 100 students should have a sample size of at-least 30 students.
- This condition approximates that the sample collected is also random and and follows a normal distribution like the population ( i.e total number of students = 100 ) itself.
- However, the spread of the data sigma = 3,000 is very large but it does not invalidates the condition of normally distributed sample, it only means that values are spread wide about the mean = 400.
Answer:
242/81 is the answer.
Step-by-step explanation:
Amount of lemonade in each pitcher = Seven quarters = gallons
We have to determine the amount of lemonade in 5 and 1/2 pictures.
First, we will determine the amount of lemonade in 5 pitchers.
So, Amount of lemonade in 5 pitchers = = gallons.
Now, we will calculate the amount of lemonade in half of the pitcher = = gallons
Total amount of lemonade in 5 and half a pitcher =
LCM of 4 and 8 is '8'.
=
= gallons.
Therefore, the total amount of lemonade in 5 and 1/2 pictures = gallons = gallons.
Answer:
it would be C because they are positive
