Acalculus exam has a mean of µ = 73 and a standard deviation of σ = 4. trina's score on the exam was 79, giving her a z-score of +1.50. the teacher standardized the exam distribution to a new mean of µ = 70 and standard deviation of σ = 5. what is trina's z-score for the standardized distribution of the calculus exam?

I get z = +1.8

x= 79

m= 73;s= 4;z= (x-m)/s= 1.5

hope it helps you

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
