Answer: i couldn’t find the answer to this one either
Step-by-step explanation:
Right off the bat (haha), we can eliminate B as an answer choice because adults are clearly part of the population; in fact, it says in the background information that their entire population is made of adults. A population, in this context, is the group being researched.
D isn't the correct answer; the fact that adults are the target population doesn't validify anything.
C doesn't entirely prove its point because there are other factors that go into the game being biased. In fact, I would say that this study <em>is </em>biased because the board members only attended 1 game when there are 18 teams. Their data will only pertain to fans of the 2 teams playing each other, and not represent the population as a whole.
A would be my answer for reasons stated above.
Answer:
no, I don't like quarantine.
x should be 115 because it is parallel to the one above. each line should equal 180. So 180-115= 65
y=65
[tan(y) + cot (y)]/csc (y)
tan (y) = sin (y)/cos (y)
cot (y) = cos (y)/sin (y)
csc (y) = 1/sin (y).
Now rewrite the expression with the equivalent values
[sin (y)/cos (y) + cos (y)/sin (y) ] / [1/sin (y)]
1st, let's work the Numerator only = [sin (y)/cos (y) + cos (y)].
= [(cos² (y) + sin² (y)]/ [cos (y).sin(y)]
or (cos² (y) + sin² (y) = 1, →Numerator = 1/[cos (y).sin(y)]
Denominator = csc (y) = [1/sin (y)], Then:
N/D = 1/[cos (y).sin(y)] / [1/sin (y)] = [1 x sin (y)]/ [cos (y).sin (y)] = 1/cos (y)
Or 1/cos (y) = sec (y) Q.E.D
Answer:
B
Step-by-step explanation:
You can see from the sequence 26, 44, 62, 80,.... that each term after the first is 18 larger than the previous term.
<u>The first 4 seconds' distance is given</u>, so
- 5th second distance is 80+18=98
- 6th second distance is 98+18=116
- 7th second distance is 116+18=134
To find total distance for 7 seconds, we add up all the individual distances:
26+44+62+80+98+116+134=560
Answer choice B is right.
