Answer:
Part A)
Part B) The distance between the y-intercepts is equal to 4 units
Part C) The value of h(x) will always be greater than the value of m(x) for any value of x
Step-by-step explanation:
Part A) What is the value of h(4) -m(16)
we have
For x=4
Find the equation of the line m(x)
Find the slope
take the points
(8,2) and (12,4)
The formula to calculate the slope between two points is equal to
substitute
Find the equation of the line in slope intercept form
we have
substitute
solve for b
therefore
Find m(16)
so
Part B) we know that
The y-intercept is the value of y when the value of x is equal to zero
Find the y-intercept of h(x)
For x=0
Find the y-intercept of m(x)
For x=0
therefore
The distance between the y-intercepts is equal to 2-(-2)=4 units
Part C)
Graph both equations
using a graphing tool
see the attached figure
The value of h(x) will always be greater than the value of m(x) for any value of x
Answer:
a. The proportion of vehicle speeds were between 25 and 57 mph is 68.26%
b.The proportion of vehicle speeds exceeded 57 mph is 15.87%.
Step-by-step explanation:
a. To calculate what proportion of vehicle speeds were between 25 and 57 mph we would have to make the following calculations:
Probability that the vehicle speeds were between 25 and 57 mph is given by:
P(25≤x≤57)
=P(<u>25-41 </u>≤ <u>x-μ </u> ≤ <u>57-41)</u>
16 σ 16
=P(-1≤z≤1)
=P(z≤1)-P(z≤1)
=0.8413-0.1587
=0.6826
The proportion of vehicle speeds were between 25 and 57 mph is 68.26%
b. To calcuate what proportion of vehicle speeds exceeded 57 mph, we would have to make the following calculation:
Probability that vehicle speeds exceeded 57 mph is given by
P(x>57)
=P(<u>x-μ </u> > <u>57-41)</u>
σ 16
=P(z>1)
=1-P(z≤1)
=1-0.8413
=0.1587
The proportion of vehicle speeds exceeded 57 mph is 15.87%.
