I 3. Some field goal kickers think that they will kick better if they wear a tighter shoe on their
kicking foot. To see if this is true, a kicker decides to perform an investigation that compares
wearing a regular sized shoe on his kicking foot and wearing a tighter shoe on his kicking
foot. He will attempt 10 field goals with each type of shoe. To determine which type of shoe
to use for each kick, he will place 20 note cards in a hat, 10 labeled 'tight" and 10 labeled
"regular" and randomly draw a card before each kick.
(a) Explain how you know that this is an experiment and not an observational study.

the answer is b.)

< 1=< 2

the square root of what number? if you add that, then someone will probably answer the question.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
