Answer:
D
Step-by-step explanation:
4 out of 5 games is 80%:
So if we know, as a rule that "Joel scores in 80% of his games.", the probability that he will score in 80% of his games is 1 - that is, we know it for sure
100% sure
Answer:
Step-by-step explanation:
Given
Length of curve

Length of curve is given by
over interval a to b
comparing two we get


integrating


Curve Passes through (1,2)


curve is

In order for two linear lines to be perpendicular, the product of their gradient must be -1.
Let's take y = x + b and y = -x + b
This is already in the form: y = mx + b, where m is 1 and -1 respectively.
Since the product of their gradient is -1, they are said to be perpendicular.
