Answer:
Step-by-step explanation:
The easy way to make 2 perpendicular lines is let one be x = 3 and let y = 2.
The third line can be anything that has a minus sign in front of the x. See the graph below. The third line cannot be perpendicular to the other 2.
Sorry, the bottom of the graph got cut off. If you print out the graph and extend the vertical line and the slanted line, you will see how this works.
The three lines are
- x = 3
- y = 2
- y = -x - 2

Given : Henry has collected data to find that the typing speeds for the students in a typing class has a normal distribution.
Mean :
Standard deviation :
Let x be the random variable that represents the typing speeds for the students.
The z-score :-
For x= 51
Using the standard normal distribution table ,the probability that a randomly selected student has a typing speed of less than 51 words per minute :-
Hence, the probability that a randomly selected student has a typing speed of less than 51 words per minute = 0.8413
