Answer:

-6
2

Step-by-step explanation:

$( - 2) + ( 3 - 7)$

$- 2 + (3 - 7)$

$- 2 + - 4$

$- 2 - 4$

$\boxed{\green{ = - 6}}$

◇◇•◇◇

$( - 1) \times ( - 2)$

$1 \times 2$

$\boxed{\green{= 2}}$

Mean, Median, Mode And Range What Do You Do For Each Of These

Umnica [9.8K]

Mean, Median: Is the middle number of the ordered data or the mean of the middle two numbers

Mode: The number or numbers that occur most often

Rage: The difference between the lowest and highest values

Example:

5, 6, 6, 9, 11, 13, 13, 13, 24, 28, 33, 48

Median and Mean: 13
Because is the middle number

Mode: 13
Because is the number that repeats more often

Rage: 43
Because 48 the highest number minus 5 the lowest number equals 43
48-5=43

Find the absolute maximum and minimum of the function on the given domain. f (x comma y )equals 8 x squared plus 7 y squared on

pickupchik [31]

Answer:

the maximum value is 7

The minimum value is 0

Step-by-step explanation:

Step One : Interpret the question

The above question can be written like

The Equation

$f(x,y) = 8x^2 +7y^2$

The diagram of the triangular plate and the bounded lines is shown on the first uploaded image

From the diagram $f(0,0) = 8(0)^2 +7(0)^2 =0$

$f(1,0) =8(1)^2 + 7(0)^2 = 8$

$f(0,1) =8(0)^2 + 7(1)^2 = 7$

Partial differentiation of the equation w.r.x

$A =\frac{\delta f}{\delta x } = 16x$

Partial differentiation of the equation w.r.y

$B =\frac{\delta f}{\delta y } = 14y$

Looking at the diagram the maximum value is 7 i.e at (x , y) = (0,1)

The minimum value is 0 i.e (x , y) = (0,0)

The cost, in dollars, of producing x yards of a certain fabric is C(x) = 1500 + 12x − 0.1x2 + 0.0005x3. (a) Find the marginal co

Flauer [41]

Answer:

(a) The marginal cost function is 12 - 0.2x + 0.0015x^2

(b) C'(500) = $287. C'(500) indicates the rate at which cost is rising with respect to production level of the fabric when x = 500.

C'(500) predicts the cost of producing the 500th yard of fabric.

(c) C'(500) = $287

The cost of manufacturing the 501st yard, C(501) = $287.6505.

C(501) is approximately the same as C'(500).

Step-by-step explanation:

(a) The marginal cost function is obtained by differentiating the cost function (C) with respect to the number of yards of fabric produced (x)

C(x) = 1500 + 12x - 0.1x^2 + 0.0005x^3

C'(x) = 12 - 0.2x + 0.0015x^2

(b) C'(x) = 12 - 0.2x + 0.0015x^2

C'(500) = 12 - 0.2(500) + 0.0015(500)^2 = $287. This means that cost is rising at a rate with respect to the production level when x = 500.

C'(500) = $287 predicts that the cost of producing the 500th yard of fabric is $287.

(c) C(x) = 1500 + 12x - 0.1x^2 + 0.0005x^3

C(501) = 1500 + 12(501) - 0.1(501)^2 + 0.0005(501)^3 = $287.6505 is approximately the same as C'(500) which is $287
