The probability distribution for the daily sales at Michael's Co. is given below. Daily Sales (In $1,000s) Probability 40 0.1 50 0.4 60 0.3 70 0.2 The expected daily sales are:$ (Write answer with no decimal places and as a DOLLAR value, i. e. input 2000 to represent $2,000).

Using the discrete distribution given, it is found that the expected daily sales are: $56000.

In this problem, the distribution is:

Hence, the expected value is:

The expected daily sales are: $56000.

The expected daily sales are: $ 56,000

Step-by-step explanation:

According to the information provided, expected daily sales are:

Multiplying each range of sales by its probability:

40,000 * 0.1 = 4,000

50,000 * 0.4 = 20,000

60,000 * 0.3 = 18,000

70,000 * 0.2 = 14,000

In consequence, we add up the values from above to calculate the expected daily sales amount:

Expected daily sales = 4,000 + 20,000 + 18,000 + 14,000

Expected daily sales = 56,000

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
