Answer:

a. 0.32

b. 0,72

c. $13200

d. No

Step-by-step explanation:

Suppose we are interested in bidding on a piece of land and we know one other bidder is interested. The seller announced that the highest bid in excess of $10,400 will be accepted. Assume that the competitor's bid x is a random variable that is uniformly distributed between $10,400 and $14,600.a. Suppose you bid $12,000. What is the probability that your bid will be accepted (to 2 decimals)?b. Suppose you bid $14,000. What is the probability that your bid will be accepted (to 2 decimals)?c. What amount should you bid to maximize the probability that you get the property (in dollars)?d. Suppose that you know someone is willing to pay you $16,000 for the property. You are considering bidding the amount shown in part (c) but a friend suggests you bid $13,200. If your objective is to maximize the expected profit, what is your bid? (Options: 1. Stay with the bid in part (c) or 2. Bid $13,200 to maximize profit)What is the expected profit for this bid (in dollars)?

a=10400

b=14600

probability density is gotten by inverse of difference in boundaries

\frac{1}{14600-10400} =f(y)

0.0002

a. for probability x<12000\int\limits^12000_10400 {f(y)} \, dy\\\int\limits^12000_10400 {0.0002} \, dy

(0.0002) from 12000 to 10400

0.32

b. probability that y x<14000

integrate f(y)dy

between 14000 and 10400

0.0002x

0.72

c.

Bid at most 13200 to be sure that it will be at maximum

d. No, if the house is sold for 16000 you could make a profit of $2800, because the house is $13200. You will run at loss is you bid less

Describe the effect on the area of a circle when the radius is doubled
galina1969 [7]

Answer:

The original area would be multiplied by the scale factor of 2² to get the new area.

Step-by-step explanation:

If you double the radius lets so lets do an example

(a=πr²) so

if x is the radius the area would be x²π      

double the radius so 2x then the area would be

(2x)²π so 4x²π

4x²π/x²π= 4 so its 4 times greater or

D the last answer or The original area would be multiplied by the scale factor of 2² to get the new area.

Which equations are true?<br>A: -x = -x + x + 0<br>B: -x = 0 + (-x)<br>C: None Of The Above ​
Leto [7]
Answer: B
Explanation: if you look at A and try to combine like terms, you will add the -x on the right side the the one on the left, cancelling out the x on the left. then you have 0=x+0, and unless x=0, it is not true.
With B, when you add x to the -x, you cancel it out, giving you 0=0, which is true. hope it helps!

A bicycle store costs ​$3300 per month to operate. The store pays an average of ​$75 per bike. The average selling price of each
Klio2033 [76]
S=Selling price 135
V=Variable cost 75
F=Fixed cost 3300
Let quantity be Q
The formula to break even is
135Q-75Q-3300=0
Solve for Q
60Q-3300=0
60Q=3300
Q=3300/60
Q=50
So the store must sell 50 bicycles to break even

Hope it helps!

-3.6,-5.4,-8.1,-12.15 arithmetic or geometric or neither.
Brums [2.3K]

Answer:

Geometric Sequence

Step-by-step explanation:

1. Check the difference.

The difference between the 1st and 2nd term

( - 5.4) - ( - 3.6) =  - 1.8

The difference between the 2nd and 3rd term

( - 8.1) - ( - 5.4) =  - 2.7

The difference is not the same. Therefore, it is not an arithmetic sequence.

2. Check the ratio

The ratio between the 1st and 2nd term

( - 5.4) \div ( - 3.6) = 1.5

The ratio between the 2nd and 3rd term

( - 8.1) \div ( - 5.4) = 1.5

The ratio is the same. Therefore, it is a geometric sequence.
