Why is it necessary to check that n modifyingabove p with caret greater than or equals 5np≥5 and n modifyingabove p with caret g
yKpoI14uk [10]
It is important to check both conditions
np ≥ 5
nq = n(1 - p) ≥ 5
when you try to approximate a binomial distribution with a normal distribution.

If these two conditions are verified, it means that the sample is "big enough" to use the approximation, otherwise, the normal distribution does not fit well enough the binomial distribution and the values of mean, etc, could be different. 
Therefore if those conditions are not verified, the normal distribution is not suitable to represent the binomial distribution.

Describe the error found in m&lt;1
bixtya [17]

Answer:

The sum of all angles should be 180°

Step-by-step explanation:

Sum of all angles in a triangle = 180°

115° + 39° = 154°

180° - 154° = 26°

The student found 206°, lets add 206° to 154° and see what we get.

206° + 154° = 360°

Prediction : The student may have forgotten that the sum of all angles in a triangle equals 180° and not 360°

Answer: The sum of all angles should be 180°

If my answer is incorrect, pls correct me!

Marcus are 1/3 of a pizza on Monday night. He then ate 1/4 of the remaining pizza on Tuesday. Which of the following expressions
OleMash [197]

Answer:

B would be correct.

Step-by-step explanation:

You have to subtract the 1/3 and 1/4 by the whole pizza (1) otherwise you never had a whole pizza according to your equation. By doing 1-1/3 you solve for the amount left on Monday, and when you subtract 1/4 from the number you just got, you have solved for the total amount left on Tuesday.

1-1/3=2/3

2/3-1/4= 2/3 * 4/4 - 1/4 * 3/3 =

8/12-3/12= 5/12 of a pizza left
