1. a construction company is planning to bid on a building contract. the
bid costs $1,500 and has an 80% chance of being accepted. if accepted,
the company will receive $40,000 dollars. find the expected value.

The expected value of construction company is $30500.

Solution:

Given, A construction company is planning to bid on a building contract.  

The bid costs $1,500 and has an 80% chance of being accepted.  

If accepted, the company will receive $40,000 dollars.  

We have to find the expected value.

We know that,  

Expected value = probability amount gained by bidding – bid amount

Expected value = 80% x 40000 – 1500

Expected value = 0.8 x 40000 – 1500

Expected value = 32000 – 1500

Expected value = 30500

Hence, the expected value is $30500.

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
