Answer:
Center (4,1)
Radius r = 4
Step-by-step explanation:
Complete the square to fill in the standard circle equation:
- , (h,k) is the center, r is the radius
Use formula:
therefore,
(h,k) = (4,1)
r = 4
X=minutes passed
y=number of papers
24x=y
24x=138
138/24=5.75
x=5.75
it will take 5.75 minutes to print 138 copies

µ = 50
σ = 8
We are supposed to find the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees
Formula :
at x = 46
Refer the z table for p value
p value = 0.3085
at x = 58
Refer the z table for p value
p value = 0.8413
Hence the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees is 0.5328
