Here, the expression is under modulus = |−32|

Anything under modulus means, that magnitude with +ve sign, so -ve sign would get neglected.

In short, Your Answer would be 32

Hope this helps!

The difference between the prediction interval and the confidence interval is that A. the prediction interval is narrower than t

Kitty [74]

Answer:

The prediction interval provides an interval estimation for a particular value of y while the confidence interval does it for the expected value of y.

Step-by-step explanation:

A. the prediction interval is narrower than the confidence interval.

the prediction interval is always wider than the confidence interval.

B. the prediction interval provides an interval estimation for the expected value of y while the confidence interval does it for a particular value of y.

False

C. the prediction interval provides an interval estimation for a particular value of y while the confidence interval does it for the expected value of y.

True

D. the confidence interval is wider than the prediction interval.

If the range of the function f(x)=x/4 is {28,30,32,34,36}, what is its domain

marissa [1.9K]

Hello:
x/4 = 28 .... x = 112
x/4 = 30 .... x = 120
x/4 = 32 .... x = 128
x/4 = 34 .... x = 136
x/4 = 36 .... x = 144
the domain is : {112,120,128,136,144}

SUppose the total cost C(x) to manufacture a quantity x of insecticide (in hundreds of liters) is given by

Hitman42 [59]

Answer:

a) $C(x)$ is increasing in two regions: (i) $(+\infty, 8\,s)$ and (ii) $(10\,s,+\infty)$ .

b) $C(x)$ decreases in $(8\,s, 10\,s)$ .

Step-by-step explanation:

Let $C(x) = x^{3}-27\cdot x^{2}+240\cdot x +850$ , where $x$ is the quantity of insecticide, measured in hundreds of liters, and $C(x)$ is the total manufacturing cost as a function of the quantity of the insecticide, measured in US dollars. A possible approach to determine which regions of $C(x)$ are decreasing and increasing by means of the first derivative and graphing tools. The first derivative of the function is:

$C'(x) = 3\cdot x^{2}-54\cdot x+240$ (1)

Please notice that regions where C(x) is increasing has $C'(x) > 0$ , whereas $C'(x) < 0$ when $C(x) < 0$ .

We notice that $C(x)$ is increasing in two regions: (i) $(+\infty, 8\,s)$ and (ii) $(10\,s,+\infty)$ . Besides, $C(x)$ decreases in $(8\,s, 10\,s)$ .
