Question the construction of the tminus−statistic for a oneminus− and a twominus−sided hypothesis a. uses plus or minus±1.96 for the twominus−sided test, but only +1.96 for the oneminus−sided test. b. is different since the critical value must be 1.645 for the oneminus−sided hypothesis, but 1.96 for the twominus−sided hypothesis (using a 5% probability for the type i error). c. depends on the critical value from the appropriate distribution. d. is the same.

Malia is observing the velocity of a cyclist at different times. after two hours, the velocity of the cyclist is 15 km/h. after five hours, the velocity of the cyclist is 12 km/h. part a: write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times. show your work and define the variables used. (5 points) part b: how can you graph the equations obtained in part a for the first 12 hours? (5 points) if you can try and make this as little confusing as you can

Atriangle has verticals at b(-3,0), c(2,-1), d(-1,2). which transformation would produce an image with verticals b”(-2,1), c”(3,2), d”(0,-1)?

Which expression is equal to (f+g)(x)?
