Answer:
as x -> -∞, y-> ∞ and as x-> ∞, y -> -∞ - <u>Second option</u>
Step-by-step explanation:
If you look carefully to the left, when x becomes negative the y value becomes positive. On the right, x becomes positive and y becomes negative.
28. THATS THE CORRECT ANSWER
90,000 becuase 63,824 is rounded down to 60,000 and 29,452 is rounded up to 30,000. 60,000+30,000 is 90,000
So we are given that the mean is 42% and the sd (standard deviation) is 8%
Assuming our data is normal we can use the 68-95-99 rule
So one thing you should realize is that 42% + 8% is 50% which is passing. That is one standard deviation higher. So we use:
100 - 68 - 13.5 - 2.35 - 0.15 = 16. That means 16% of students passed the test. Which is terrible. They probably need to hit the books more.

Hopes this helps!
Thing is, you didn't give us the choices!
