Answer:
About 1.23 standard deviation above the mean
Step-by-step explanation:
From what we have here, we need to calculate the difference between the given value and the mean and divide by the standard deviation
That would be through calculating the z score as follows;
z-score = (x - mean)/SD
where x is the given value
z-score = (87-71)/13 = 1.23
Since the score is bigger than the mean, the correct choice here is that the score is about 1.23 standard deviation above the mean
Answer:
420% of 85 = 357
Step-by-step explanation:
85/x=100/420
(85/x)*x=(100/420)*x - we multiply both sides of the equation by x
85=0.23809523809524*x - we divide both sides of the equation by (0.23809523809524) to get x
85/0.23809523809524=x
357=x
x=357
