Option c. is correct
Step-by-step explanation:
The standard deviation is a measure of the amount of dispersion in a set of values.
Mean of a normal distribution (m) = 154
Standard deviation (s) = 15
z-score = 2.2
To find: value (x) that has a z-score of 2.2
z-score is given by
Put
Option c.is correct
Answer:
(9*2)*5
Step-by-step explanation:
No matter if you move the parenthesis it stays the same answer :)
You find slope by having two coordinates okay, for example the two could be ( 1,3 ) & (2,4) theres a x1, y1 which 1 is x1 and y1 is 3. and there’s x2 and y2 where x2 is 2 & y2 is 4. and now you use this equation m= y2-y1 / x2-x1 where m means slope. and there’s your answer. so for the example i put the answer would be 1. because 4-3 = 1 over 2-1 = 1. so that’s 1 over 1. which is just one. please tell me if this explanation helped!
