Answer:

so correct option is c. 1.51

Explanation:

given data

random sample n = 81

average speed x = 60 mph

standard deviation σ = 13.5 mph

interval estimate  μ =  86.9%

to find out

the value of the z

solution

we have given  μ =  86.9%

so we get here z critical value for the confidence level =  86.9 %

we will use here standard normal table

so z value for 86.9% is 1.51

so correct option is c. 1.51

coldgirl [10]

Answer:

Explanation:

Break even point=fixed cost/ contribution margin per unit

Units to be sold to get target operating income=(fixed costs+ target operating income)/contribution margin per unit

1. Revenue=10%×1600=$160 per ticket

Contribution per ticket=$100-$42=$58 per ticket.

Fixed cost=$29,500

Break even units:$29,500/$58=508.6 tickets

Units to be sold to get target operating income:(29500+$12000)/$58=715.5 tickets

2. Revenue=10%×1600=$160 per ticket

Contribution per ticket=$100-$35=$65 per ticket.

Fixed cost=$29,500

Break even units:$29,500/$65=453.8 tickets

Units to be sold to get target operatig income:(29500+$12000)/$65=638 tickets

3.

Revenue=$50 per ticket

Contribution per ticket=$50-$35=$15 per ticket.

Fixed cost=$29,500

Break even units:$29,500/$15=1966 tickets

Units to be sold to get target operating income:(29,500+$12,000)/$15=2766 tickets

4.

Revenue:$55(fixed comission fee)+$5(delivery fee)=$60 per ticket

Contribution per ticket=$60-$35=$25 per ticket.

Fixed cost=$29,500

Break even units:$29,500/$25=1180 tickets

Units to be sold to get target operating income:(29,500+$12,000)/$25=1,660 tickets

Retirement Investment Advisors, Inc., has just offered you an annual interest rate of 4.1 percent until you retire in 45 years.
grigory [225]

Answer:

If you wait one year, in 45 years you will have $16,624.04 more than investing today.

Explanation:

Giving the following information:

Option 1:

Initial investment= $11,500

Number of years= 45

Interest rate= 4.1%

Option 2:

Initial investment= $11,500

Number of years= 44

Interest rate= 4.7%

To calculate the future value for both options, we need to use the following formula:

FV= PV*(1+i)^n

<u>Option 1:</u>

FV= 11,500*(1.041^45)= $70,142.41

<u>Option 2:</u>

FV= 11,500*(1.047^44)

FV= $86,766.45

If you wait one year, in 45 years you will have $16,624.04 more than investing today.
