Answer:
OB. (2, 4), (3, 9), (4, 16), (5, 25)
Step-by-step explanation:
none of the points in this ordered pair have the same x-pos. In all the other options, at least 2 of the points have the same x-pos, preventing them from being functions. Therefore, OB is the only right answer.

Answer:
y=5/41x
Step-by-step explanation:
Alright, so we can get imagine two points. Imagine that the y axis is miles and the x axis is minutes. When bianca runs 0 miles, she would have run for 0 minutes, and we know that when Bianca runs 5 miles, she would have run for 41 minutes.
We can use slope formula using the change in y over change in x
So substituting values, we would get (5-0)/(41-0) or 5/41
slope is the letter m in the formula y=mx+b
so our equation would be , b being the y intercept, which would be 0 as you cant run anything when no time has passed
Knowing all of this. the final equation is
3/4 mate, since a fraction is almost always under 1, (except for improper ones), 3/4 should be 0.75 in decimal form.
Answer:
Part A: Yes, there should be a strong negative correlation between number of hours of internet browsing and score on math test. Justification: By calculating the correlation coefficient it is about -1. This means there is a strong negative correlation. Part B:y=-2x+95 Part C: The slope indicates that scores on a math test decrease by two for every hour internet browsing. The y-intercept indicates the score you have when browsing 0 hours on the internet.
Step-by-step explanation:
I hope this helps :D. I recommend getting a t-inspire calculator if you don't already have one. It can be so helpful when solving these types of problems.
