Answer:
Given that 162 is 81% of 200, we can affirm that the percentage of students who will attend college after high school has increased.
Step-by-step explanation:
Given that results from previous studies showed 76% of all high school seniors from a certain city plan to attend college after graduation, if a random sample of 200 high school seniors from this city reveals that 162 plan to attend college, to determine if this indicates that the percentage has increased from that of previous studies, the following calculation must be performed:
200 x 0.76 = 152
200 = 100
162 = X
162 x 100/200 = X
16,200 / 200 = X
81 = X
Thus, given that 162 is 81% of 200, we can affirm that the percentage of students who will attend college after high school has increased.

Answer:
1. D
2. B
3. A
4. C
Step-by-step explanation:
1. Vertical angles are a pair of opposite angles formed by the intersection of lines. Choice D has two lines intersecting, and two opposite angles formed by it.
2. Adjacent angles are two angles that have a common vertex and common side but do not overlap. Choice B is two angles with a common vertex and common side, and they don't overlap.
3. Supplementary angles are angles that add up to 180 degrees/make a straight angle. Choice A has two angles that add up to 180 degrees, and the two angles combined make a straight angle/line.
4. Two angles are called complementary angles if they add up to 90 degrees and form a right angle. Choice C has two angles that form a right triangle, meaning it adds up to 90 degrees.
