Answer:
The spinner has 6 equal-sized slices, so each slice has a 1/6 probability of showing up.
I guess that we want to find the expected value in one spin:
number 1: wins $1
number 2: wins $3
number 3: wins $5
number 4: wins $7
number 5: losses $8
number 6: loses $8
The expected value can be calculated as:
Ev = ∑xₙpₙ
where xₙ is the event and pₙ is the probability.
We know that the probability for all the events is 1/6, so we have:
Ev = ($1 + $3 + $5 + $7 - $8 - $8)*(1/6) = $0
So the expected value of this game is $0, wich implies that is a fair game.
Find a percent of a quantity as a rate per 100 (e.g., 30% of a quantity means 30/100 times the quantity); solve problems involving finding the whole given a part and the percent.
Answer:
the answer is d: y=-2x-10
Answer:
break even point = 8000 socks produced or $36000 in costs
Step-by-step explanation:
the cost function of the firm is
total cost = fixed cost + variable cost = $20000 + $2*Q
where Q= number of socks
the revenue from sales is
sales = Price* Q = $4.50*Q
the break even point is reached when the net profit is = 0 ( that is, the total cost is equal to the revenue from sales) , then
total cost = sales
$20000 + $2*Q =$4.50*Q
Q= $20000/($4.50-$2) = 8000 socks
that represents
total cost = $20000 + $2*8000 = $36000
then
break even point = 8000 socks produced or $36000 in costs
Positive numbers goes by 3s and negative numbers goes by 6s
