Answer:
12.16
Step-by-step explanation:
From your question, we have the following information
Mean = u = 20
Standard deviation sd = 4
P(X>Xo) = 0.975
1-0.975 = 0.025
P(z<Xo-20/4) = 0.025
Xo-20/4 = -1.96
We cross multiply
Xo - 20 = -1.96 x 4
Xo - 20 = -7.84
Xo = -7.84+30
Xo = 12.16
12.16 is the value of Xo and therefore the answer to this question.
Thank you!
Answer:
y = x - 1
Step-by-step explanation:
<u>Slope-intercept form:</u>
y = mx + b
-> m is the slope
-> b is the y-intercept
<u>Our give:</u>
-> slope (m) is
-> goes through (-3,-3)
- A point cannot be a ray (using "{") so I assumed it is a normal coordinate point
<u>To solve:</u>
-> Plug in the slope, plug in the point, and solve for b
y = mx + b
y = x + b
(-3) = (-3) + b
-3 = -2 + b
-1 = b
-> y = x - 1
