Answer:

(f+g)(x) = 4 x^2 + (3/2) x - 7

Answer (c) on your list

Step-by-step explanation:

f+g (x) = f(x) + g(x) = x/2 - 3 + 4 x^2 + x - 4

combine the terms in "x" = x/2 + x = (3/2)x

combine the numerical terms: - 3 - 4 = - 7

Then the final expression is:

(f+g)(x) = 4 x^2 + (3/2) x - 7

The amount of time it takes for a student to complete a statistics quiz is uniformly distributed between 30 and 60 minutes. The

Oliga [24]

Answer:

37.5 minutes

Step-by-step explanation:

Let the amount of time it takes a student to complete a statistics quiz be = t

t is uniformly distributed between 30 minutes and 60 minutes

The professor wants to reward with bonus marks, students who are in the lowest quarter of t

<em>- What value of t should he use as the cutoff for awarding bonus marks?</em>

A quarter of any number is 1/4 of it.

Now, the range of t (the difference between the highest and lowest values of t) is 60 - 30 = 30

1/4 of 30 = 7.5

The lowest quarter of t is hence between 30 and 37.5

So the cutoff for awarding bonus marks is t = 37.5minutes

INTERPRETATION:

Any student who spends 37.5 minutes or below on a statistics quiz, will be awarded bonus marks.
