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:
The slope of the line= 2/3
Step-by-step explanation:
(2, 2)=(x, y) and (5, 4)=(`x, `y)
The formula for finding slope= `y-y/`x-x
4-2/5-2
2/3
Therefore, the slope=2/3
Awnser is C. Random cuz thats how i chose this answer... its was random
<span> |6 – v| < 9 can be written as two separate inequalities:
+(6 - v) < 9, or -v < 3, or v > -3: (-3, infinity)
-(6-v) < 9, or -6 + v < 9, or v<15: (-infinity, 15)
These two intervals overlap: (-3,15)</span>
D is the only answer................
