Answer:
I believe that D is the answer.
Step-by-step explanation:
The Y and X axis goes up by 1/8, so the Y value is 5/8 and the X value is -1/4.
(For the X axis, you need to simplify.)
Answer:
The HCF = 3.
Step-by-step explanation:
The prime factors of
234 = 2*3*3*13,
and of 111 = 3*37.
The only common factor is 3.
Answer: 0.1841
Step-by-step explanation:
Given: Mean : 
Standard deviation : 
The formula to calculate z-score is given by :_

For x= 9, we have

For x= 10, we have

The P-value = 

Hence, the probability that at your next exam, you will have a stress level between 9 and 10 = 0.1841
Answer:

Step-by-step explanation:
Your equation is in slope-intercept form, ...
y = mx + b . . . . line with slope m and y-intercept b
with m = -1/2 and b = 3.
This tells you the point y=3 on the y-axis is one point on the graph. (That is the y-intercept.) It also tells you the line decreases 1 unit for each 2 units to the right.
m = rise/run = -1/2 ⇒ rise = -1 for run = 2
So, another point that is 2 right an 1 down from (0, 3) is (2, 2). Your line will go through these two points. Plot them and draw the line through them.
