The grades on a language midterm at Santa Rita are roughly symmetric with u = 70 and o = 5.5 Ishaan scored 72 on the exam.

Find the z-score for Ishaan's exam grade. Round to two decimal places.

0.36

Step-by-step explanation:

Given that:

Mean = 70

Standard deviation = 5.5

score (x) = 72

Formular for obtaining Standardized score (Zscore) :

Zscore = [score (x) - mean] / standard deviation

Hence,

Zscore = (72 - 70) / 5.5

Zscore = 2/ 5.5

= 0.3636363

Zscore = 0.36 ( 2 decimal place)

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
