Select the correct answer from each drop-down menu. Gilbert is training for a bike race. As part of his training, he does practice rides on portions of the actual race course. Gilbert's first practic
covers 5 miles of the course, and his second practice ride covers 9 miles of the course. Between these practice rides, he increases his ave
speed by 2 miles/hour.
These functions model the time it took Gilbert to do each practice ride, where x is his speed during the first practice ride.
Practice Ride 2
Practice Ride 1
a(x) =

+ 2
The denominator of the function that models practice ride 2 represents the
To find a function that models the total amount of time Gilbert spent doing practice rides on the race course,

If the measure of angle 1 is 110 degrees and the measure of angle 3 is (2 x+10 degree), what is the value of x?

Astudent is solving a system of equations by substitution and comes up with the solution 3 = 3. assuming that he solved the problem correctly, which of the following can be said about this system of equations?

The weibull distribution is widely used in statistical problems relating to aging of solid insulating materials subjected to aging and stress. use this distribution as a model for time (in hours) to failure of solid insulating specimens subjected to ac voltage. the values of the parameters depend on the voltage and temperature; suppose α = 2.5 and β = 190. (a) what is the probability that a specimen's lifetime is at most 250? less than 250? more than 300? (round your answers to four decimal places.) at most 250 less than 250 more than 300 (b) what is the probability that a specimen's lifetime is between 100 and 250? (round your answer to four decimal places.) (c) what value is such that exactly 50% of all specimens have lifetimes exceeding that value? (round your answer to three decimal places.) hr
