Answer: So here we have a function F(x) = y. and you give some of the points (x,y).

this are (10, 409) , (50, 1889) , (125, 4664)

then, if we assume a linear relationship, we could find the slope using the next formula:  s = \frac{y2 - y1}{x2 - x1}

then for the first two points we get: s = \frac{1889 - 409}{50 - 10}  = 37

and the slope between the second and third point is:

s = \frac{4664 - 1889}{125 -50}= 37

So we have the same slope in the two segments, and it's safe to assume that our function is linear. Now we need to find the x-intercept

then F(x) = 37x + b

and F(10) = 370 + b = 409

b = 409 - 370 = 39

So our function is F(x) = 37*x + 39

then if x = 200, F(200) = 37*200 + 39 = 7439.

So the correct answer is B.

I would say the answer is D. 7837. Since the common ratio between the x’s and y’s were are 39.5 so multiplying that times 200 gives something around 7900 so, (rounding down) the answer would be D. I really hope that helped! Also please correct me if I am wrong... thanks!

Rama09 [41]
If the test gives a positive result for an infected person 98% of the time, that means that 2% of the time, it gives a negative result for an infected person, which would be a false negative.

If the test is 97% accurate for non-infected people, that means that it gives a negative result 97% of the time. So a positive result will be given 3% of the time for non-infected people, which is a false positive.
