Your friend believes that he has found a route to work that would make your commute faster than what it currently is, under similar conditions. to test this claim, you and your friend time the commute from your house to the building where you work over a random set of days, and you flip a coin each day to determine who takes which route. each trip is done at the exact same time of day. find the test statistic and degrees of freedom for an appropriate hypothesis test using the data set below. let the difference d for each day be computed as d=new route time−current route time. assume that the times are normally distributed. round the test statistic to three decimal places.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

rotation point l

step-by-step explanation:

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)

you should talk someone who owns the website about it. you did not deserve to have all that hard work and time taken away. id watch videos of little puppies to cool you down, and maybe some nacho cheese doritos.
