Answer:

3.5 hr per exam

Step-by-step explanation:

Hello,

Let's have x represent hours for each exam. The equation is:

Subtract 2 from both sides and divide by 4 and we get:

x=3.5 hours for each exam

Make sense?

Given the following graph of a system of inequalities, the point (3, 2) _____________.
uysha [10]
That point does not satisfy either inequality. 

You can tell it does not satisfy the first portion, due to it being under the shaded line. Secondly, the dotted line goes through it, but that fact that it is dotted makes it not included.

Recall Marginal Cost is the derivative of Total Cost, and Fixed Cost is the cost of producing zero units.
olga nikolaevna [1]

Answer:

The total cost of producing 91 units of ACME rocket fuel is $3999.99.

Step-by-step explanation:

The Marginal Cost is given by the following function

MC(q) = 200*(q+9)^{-5}

The total cost function is the integrative of the marginal cost function. So:

TC(q) = \int {MC(q)} \, dq

TC(q) = \int {200*(q+9)^{-5}} \, dq

TC(q) = -50*(q+9)^{-4} + K

In which K, the integrative constant, is the fixed cost. So K = 4000.

1. Find the total cost of producing 91 units of ACME rocket fuel.

This is TC(91).

So

TC(91) = -50*(91+9)^{-4} + 4000 = 3999.99

The total cost of producing 91 units of ACME rocket fuel is $3999.99.

miskamm [114]

Answer:

Yes, you can buy the used car with $849.92 left over.

Step-by-step explanation:

20 hours per week for 52 weeks = 1040 hours

1040 hours at $8 = $8320 per year

FICA = 8320 x 0.0565 = $470.08

8320 - 470.08 = $7849.92

yawa3891 [41]

Answer:

Unsure, take a look at the visualisation:

desmos(dotcom)/calculator/fjze0od81o

Replace the (dotcom) with ".com"    (   links are not allowed :(   )

Explanation:

None of the points look as though they are an outlier from the line of linear regression, although (29,62) looks furthest from the line so could be a possible answer although I would probably say there is no outlier.
