Answer:

Step-by-step explanation:
For normal distributions only, all data falls within approximately 68% of one standard deviation, 95% of two standard deviations, and close to 100% of three standard deviations. The standard deviation is far too small to represent two or three standard deviations, hence
.
*Important: This problem would be unsolvable if the question did not say her cuts were normally distributed, because the information above is only applicable to normal distributions.
Answer:
3100
Step-by-step explanation:
Answer: -6.5x+4.4
Step-by-step explanation:
2(4.25 + 2.25) = 2(6.50) = 13...this is the cost without the tax
13 + 0.05(13) = 13 + 0.65 = 13.65 <=== total with the sales tax added
Answer:
Denote O as center of circle, draw OA, OC.
As property of tangent line from outside of circle (angle OAD = angle OCD = 90 deg):
=> AOC + D = 180
Moreover, angle AOC = 2 x angle B = 2 x 65 = 130
=> D = 180 - 130 = 50 deg
Hope this helps!
