Answer:
The expression which gives the probability that she will select two red cubes = 5/12 * 4/11 ....
Step-by-step explanation:
According to the statement there are 4 red cubes and 7 white cubes.
The total number of cubes are = 7+5 = 12
If she picks up one red cube then the number of ways of picking up red cubes out of 12 is = 5/12
If she picks up 2nd red cube then the number of ways of picking up 2nd red cube = 4/11
Therefore the expression which gives the probability that she will select two red cubes = 5/12 * 4/11 ....
Subtract the point A x-coordinate from the midpoint x-coordinate (final-initial) to find the distance between them. This will give you 3. Multiply the by 2 because the midpoint is halfway between point A and B.
Answer:
(2c³ -20c² -10c) -(c² -40c +100)
Step-by-step explanation:
<u>Profit</u>
For a problem involving cost, revenue, and profit, you are expected to know that <em>profit is the difference between revenue and cost</em>. That is, if it costs you $2 to make a necklace you sell for $10, your profit is $10 -2 = $8.
<u>Problem</u>
The problem gives you polynomial expressions for revenue and cost, and asks you to combine them to make an expression for profit. In this first part, we simply show <em>how</em> we will combine them. (We presume a later part of the question will ask you to simplify the result.)
profit = revenue - cost
Substituting the given expressions, we have ...
profit = (2c³ -20c² -10c) -(c² -40c +100) . . . . . matches last choice
Answer:
The answer is A
Step-by-step explanation:
(-2,-3) (3,-4) (0,-1) (-7,3)
inverse means the opposite signs
(2,3) (-3,4) (0,1) (7,-3)
Fixed costs:
$350 + $120 + $170 = $640
Variable costs:
x * ( $6.50 + $3.64 ) = x * 10.14
Sales income ( total ):
x * $36.40
FC + FV - Income = 0
640 + 10.14 x - 36.40 x = 0
640 - 26.26 x = 0
26.26 x = 640
x = 640 : 26.26 = 24.37
