Suppose that the breaking strength of a rope (in pounds) is normally distributed, with a mean of 100 pounds and a standard devia
tion of 17. What is the probability that a certain rope will break before being subjected to 130 pounds?
1 answer:
Answer:
0.961
Step-by-step explanation:
To answer this, find the area under the standard normal curve to the left of 130 pounds:
Using the function normalcdf( on a TI calculator, we get:
normalcdf(-1000, 130, 100, 17) = 0.961

Let's first get the representation of tan
We also need to understand how to convert radians to degrees
For question 1
since tan > 1
It must be in either first quadrant or third quadrant as shown in the diagram above
Do the vertical line test
16. Function
17. Not
18. Not
19. Function
Find the gradient so (-5-3)/(2+1) =-8/3 input it in y=mx+c and also use the coordinates from the question
So it becomes
3=-8/3 (-1) + c
C=1/3
Y=-8/3 x+1/3
