We are interested in athletes that are training for the long jump. we run the following regression. ulifthrsrunhrsjumplong+++=a. we want to determine if an extra hour of weight training and an extra hour of running improve a person’s long jump by the same amount. write out the null and the alternative hypotheses for this test. b. reformulate the regression above in terms of a new parameter θ so that you can directly test the null hypothesis above using the regression output. c. what new variable do you have to create and which parameter would you test to assess the null hypothesis in part a?

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less

step-by-step explanation:

a)(x-2)^2+(y-1)^2=9

(picture explains)

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

60°

step-by-step explanation:

the measure angle of c in an isosceles triangle abc is 60° because in isosceles triangle,the measures of all the angles is 60°.
