It will be 18 spoonfuls because you have to do 6 times 3 which is 18.
We have been given that a set of art exam scores are normally distributed with a mean of 81 points and a standard deviation of 10 points. Kamil got a score of 78 points on the exam. We are asked to find the proportion of exam scores that are lower than Kamil's score.
First of all, we will find z-score corresponding to 78.
, where,
z = z-score,
x = Random sample score,
= Mean,
= Standard deviation.
Now we will use normal distribution table to find the probability under a z-score of that is .
Upon rounding to 4 decimal places, we will get:
Therefore, of exam scores are lower than Kamil's score.
Answer:
342
Step-by-step explanation:
you take the fifteen and devide it by its whole munber of the problem
