Suppose we are interested in bidding on a piece of land and we know one other bidder is interested. The seller announced that th

e highest bid in excess of $9,500 will be accepted. Assume that the competitor's bid x is a random variable that is uniformly distributed between $9,500 and $14,700. Suppose you bid $12,000. What is the probability that your bid will be accepted (to 2 decimals)?

Answer:

Probability (bid accepted) = 0.48

Step-by-step explanation:

Probability density is given byF(y)= 1/(b-a)

a=9500

b= 14700

F(y)= 1/(14700-9500) =1/5200=0.00019

Probability (bid accepted)= (12000-9500)÷1/5200

P( bid accepted) = 2500×0.00019=0.475 approximately 0.48

Daniele has 33 quarters and dimes in her piggy bank. The piggy bank contains a total of $4.95. Write and solve a system of equat
3241004551 [841]

Answer:the number of dimes is 22

the number of quarters is 11

Step-by-step explanation:

A dime is worth 10 cents. Converting to dollars, it becomes 10/100 = $0.1

A quarter is worth 25 cents. Converting to dollars, it becomes 25/100 = $0.25

Let x represent the number of dimes.

Let y represent the number of quarters.

Daniele has 33 quarters and dimes in her piggy bank. This means that

x + y = 33

The piggy bank contains a total of $4.95. This means that

0.1x + 0.25y = 4.95 - - - - - - - - -1

Substituting x = 33 - y into equation 1, it becomes

0.1(33 - y) + 0.25y = 4.95

3.3 - 0.1y + 0.25y = 4.95

- 0.1y + 0.25y = 4.95 - 3.3

0.15y = 1.65

y = 1.65/0.15 = 11

Substituting y = 11 into x = 33 - y, it becomes

x= 33 - 11 = 22

Cabs charge $3.60 Flag Fall plus $2.19 per km. (a) Write down an equation to calculate the cost, C, of cab fare for a distance d
Softa [21]

(a) C = 3.60+2.19d

(b) The cab fare will be $36.45 for a distance of d kilometers.

Step-by-step explanation:

Given,

Charges of Flag Fall = $3.60

Per kilometer charges = $2.19

Let,

d be the total distance.

C be the total cost for d kilometers.

(a) Write down an equation to calculate the cost, C, of cab fare for a distance d kilometres.

Total cost = Charges of flag fall + Per kilometer charges * distance

C = 3.60+2.19d

(b) Use your equation to calculate the cost of cab fare for a distance of 15 km.

Here,

d=15

Putting in Equation

C=3.60+2.19*15\\C=3.60+32.85\\C=36.45

The cab fare will be $36.45 for a distance of d kilometers.
