Answer:
Approximantly 20
Step-by-step explanation:
Circumference = pi times diameter
63/pi = diameter
Answer: 20.0535228
Answer:
-3
Step-by-step explanation:
y1-y2/x1-x2 = slope
Plug in coordinates (-1,0) and (0,-3)
-3-0/0-(-1)
-3/1
-3
50 - 5n = 15
if you need to find the number n then
50 - 5n = 15
-5n = -35
n = 7
First, solve for slope.
Formula for slope:

Plug in values:

Slope:

Second, we must plug into point-slope form.
Formula for point-slope:

Plug in the values:

And there you have your answer in point-slope form
Answer: -0.85
Step-by-step explanation: a = score-mean/ standard deviation
Mean (add them all up and divide by amount) = 18.8745
Standard deviation =
σ2 = Σ(xi - μ)2/N
= 5.333458985499
SCORE = 14.23
= -0.85
