Scrat [10]

Answer:

x < -10/7

Step-by-step explanation:

Divide both sides by -7. Because this divisor is negative, we must reverse the direction of the inequality sign, obtaining:

-7x < 10

----- < -----

-7 -7

Then x < -10/7

The correct next step that Cynthia should do is to:

D. use the arc markings to determine the radius to construct the circle

<span>The arc markings are actually used as the baseline in determining the center and the radius of the circle. The arc markings are created with the use of a compass. All other choices are completely irrelevant because what we need is the arc and not the angles. The angles do not create the circle. Letter C is also wrong because what we are trying to form is the circle and not the triangle. The triangle is already created.</span>

Answer:

Expected revenue from the single trip is $ 13.14

Step-by-step explanation:

y

p(x,y) 0 1 2 g(x)

x 0 0.025 0.015 0.010 0.05

1 0.050 0.030 0.020 0.1

2 0.115 0.075 0.050 0.24

3 0.150 0.090 0.060 0.3

<u>4 0.100 0.060 0.040 0.2 </u>

h(y) 0.325 0.27 0.18

E (x+Y) = E(X) +E(Y)

E(X)= ∑ xi g(x)i

= ( 0*0.05) + (1*0.1) + (2* 0.24) + (3*0.3) + (4*0.2)

= 0 + 0.1+ 0.48 + 0.9+0.8

=2.28

E(Y)= ∑yi h(y)

= (0* 0.325) + (1*0.27) + (2*0.18)

= 0 +0.27+ 0.36

= 0.63

E (x+Y) = E(X) +E(Y)

= 2.28 + 0.63

= 2.91

But the equation is 3x+ 10y

E(3x+ 10y)= 3E(x) + 10 E(y)

= 3(2.28) + 10 (0.63)

= 6.84 +6.3

= 13.14

Expected revenue from the single trip is $ 13.14

Sorry for bad handwriting, while there are other ways to do this, if you can just know how to simply find the legs from the two points it is very simple!

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed

Korvikt [17]

Answer:

The number of books produced at which the costs from the two methods be the same is 4668 books

Step-by-step explanation:

Here, we have

For the first production method

Fixed cost = $65,054 and variable cost per book = $8.25

For the second production method

Fixed cost = $12,539 and variable cost per book = $19.50

Therefore, let the number of books at which the to methods cost the same be M, we then have

$65,054 + $8.25 × M = $12,539 + $19.50× M

Which gives

$65,054 - $12,539 = $19.50× M - $8.25 × M

$52515 = $11.25 × M

M = $52515/$11.25 = 4668 books.
