Its not theres two y for the same x (3)
Imagine now that you put your hand in the refrigerator and pull out a piece of fruit.
mu = 1100 = population mean
sigma = 275 = population standard deviation
x = 1400 = raw score
z = z score
z = (x-mu)/sigma
z = (1400-1100)/(275)
z = 300/275
z = 1.0909090909091 approximately
z = 1.09
Convention is to round to two decimal places so that you can use a Z table to look up the area under the curve (which helps determine probability).
The positive z score is due to Paula's raw score being above the mean.
Answer:
2/5
Step-by-step explanation:
The slope is given by
m= (y2-y1)/(x2-x1)
= (4-2)/(3 - -2)
= 2/(3+2)
= 2 /5
Answer:
159
Step-by-step explanation:
10^2+(3+5)^2-5
-> 100 + (3+5)^2 -5
-> 100 + 8^2 - 5
-> 100 + 64 - 5
-> 159
