26. Do basketball players have lower ABILITY to make free-throws when shooting granny-style (underhanded)? Suppose that you go to a basketball
court and take 30 free-throws in random order-15 shots granny-style and
15 shots using the traditional style-and record the number of shots made
in each context.
(a) What are the explanatory and response variables in this experiment?
(b) What are the treatments in this experiment?
(c) Explain why it was important to randomize the order in which the shots
were taken.
(d) What variables are important to control (keep the same) during this
experiment?
(e) State the hypotheses you are interested in testing.
(f) If the experiment provides convincing evidence that you have a lower
ABILITY to make free-throws when shooting granny-style, can you conclude
that the shooting style is the cause? Explain.

c. 4 and 1/2 pounds is the answer! : )

the range of a function is the range of y-values for which it is defined, or exists. given that we are only looking at the y-values, we can already discount the first two answers as they deal with the domain of the function (range of x-values).

now, what we need to do is find the smallest and highest y-values for which the function is defined. if you'd like, you could take a ruler and start at the very bottom of the graph, find the lowest point, then move the ruler higher and higher until you reach the highest point. doing so either in your head or with an actual ruler, we can see that the lowest y-value is -5 and the highest y-value is -1.

the question now remains as to whether they are included in the range (fourth answer) or excluded (third answer). the key here is to recognise whether they are marked with an open or a closed circle. since both (-2, -5) and (2, -1) are marked with a closed circle, they are points that exist on the graph and are thus included in the range (note that if they were marked with an open circle like (4, -2) then that would signify that there is a break in the graph at that point).

thus, the fourth answer, (y | -5 ≤ y ≤ -1), is correct.

also note that usually it is good practice to scan your eye inbetween the highest and lowest point for any breaks in the graph - we do have one here at (4, -2), however -2 is still included in the range because there is another point that is included in the graph with the same y-value, ie. point (1, -2).

i hope that but if you require any further explanation don't hesitate to comment below.

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
