On a function groupset, you can't have the same X values, but you can have the same Y values. Example: If you had {(3,1) (5,1) (6,3)} it would be a function since no X values are the same.

On choice A., they all have the same Y value, but no X values are the same.
On choice B, (2,3) and (2,4) have the same X value.
On choice C, (1,3) and (1,4) have the same X value.
On choice D, they all have the same X value.

In short, your answer would be choice A, because no X values are the same.

Reflection across y=x is a special case transformation


(x,y) \rightarrow (y,x)


The original triangle has vertices A(-5,1), B(-4,3), C(-2,1), D(-3,-1) so the transformed triangle has vertices


A'(1,-5), B'(3,-4), C'(1,-2), D'(-1,-3)

The cost of tuition at a 2 year school is $14,000 per academic year. Todd is eligible for $6,500 in financial aid to cover tuiti
emmainna [20.7K]

Answer:

$625

Step-by-step explanation:

If Todd has to pay $14,000 in tuition for his school each year and uses $6,500 in financial aid each year all for 2 years, the money he needs to save can be modeled by:

2(-$14000 + $6500) + 2(12x) = 0.

x is the minimum amount of money he needs to save in order to cover this expense without debt.

Thus 2(-$14000 + $6500) + 2(12x) = 0 →

2(-$7500) + 24x = 0 → -$15000 + 24x = 0 →

24x = $15000 → x = $625

The marketing department of a sports supply store wants to estimate the percentage of adults in the town who belong to a gym.
velikii [3]
A) If you only sample people in a sports supply store, your sample will be biased.  People in a sports supply store are more likely to be people that belong to a gym.
B) While it does not have necessarily the same amount of bias as sampling people in the sports supply store, people that go to a park are generally more likely to be people that exercise or have a gym membership.
C) Taking a random sample of people in town is a good way to get a non-biased sample.  They are not necessarily predisposed to answer your question one way or another.
D) For the same reason as choice A, this is a biased sample.

C is the best choice.
