Ksenya-84 [330]2 years ago
4 0

Answer:

"6 out of 10 people" means the ratio of class:no_class is 6:4

990/10 = 99, the smallest the "class" and the "no_class" add up to is 10. And, generally, the total divides with that nicely, as in this case.

99(6) = 594 ----------- probably class

99(4) = 396 ------------------ probably no class

Total  = 990

I hope this helps

Function f (x) = 25x/x + 3 has a discontinuity at x = –3. What are Limit of f (x) as x approaches negative 3 minus and Limit of
Tatiana [17]

Answer:

<u> x approaches negative 3 to the right: </u>lim_{x\to -3^{+}}=-\infty<u />

<u> x approaches negative 3 to the left: </u>lim_{x\to -3^{-}}=\infty<u />

Step-by-step explanation:

The function we have is:

f(x)=\frac{25x}{x+3}

We have an asymptote at x = -3.

The limit of the function when x approaches negative 3 to the right will be:

lim_{x\to -3^{+}}=\frac{25x}{(-3)+3}=-\infty

It is because the function is decreasing from right to left.

And the limit of the function when x approaches negative 3 to the left will be:

lim_{x\to -3^{-}}=\frac{25x}{(-3)+3}=\infty

It is because the function is decreasing from left to right.

I hope it helps you!
