The formula for calculating the Confidence Interval is as follows:

Confidence Interval = x +- (z*s)/√N

Where:

x = mean = 10.36

z = taken from standard normal distribution table based on 95% confidence level = 1.96

s = standard deviation = 5.31

N = sample size = 30

Substituting know values on the equation:

Confidence Interval = 10.36 +- ( 1.96 * 5.31) / √30

Confidence Interval = 8.46 and 12.26

Hence the bill of lunch orders ranges from 8.46 to 12.26.

Jeremy earned $100,000 in salary and $6,000 in interest income during the year. Jeremy’s employer withheld $11,200 of federal in
iragen [17]

Answer:

Tax Due by Jeremy is $218

Explanation:

Step 1: Calculate Jeremy's total Income

$100,000 (Salary) + $6,000 (Interest Income) + $4,000 (long term capital gain)=  $110,000

Jeremy's exclusion at this point is 0.

Therefore, Jeremy's Gross income = $110,000, This is also Jeremy's Adjusted Gross Income (AGI).

Step 2: Calculate Taxable Income after deductions.

AGI= $110,000

Deductions from AGI= $23,000 (The greater of standard or itemized deduction).

Qualified Business Income Deductions (QBI)= $0 (Jeremy did not declare any personal business).

Taxable Income= AGI-Deductions- QBI Deductions

= $110,000-$23,000-0

= $87,000

Step 3: Calculate Jeremy's Tax Liability as follows:

Capital Gain is included as part of Gross Income, therefore finding the tax liability will necesitate that the capital gain be deducted and only the taxable percentage be added back.

Jeremy's tax liability = (87,000-4,000) + (4,000 x 0.15)

= ($83,000 x 15.4%) + 600

=$12,818 + 600

=$13,418

Jeremy's total tax Liability= $13,418 - $0 (non refundable tax credit) + 0 (other taxes)

Jeremy's total tax liability = $13,418

The total tax payment made by Jeremy

=(2,000 + 11,200)= $13,200

Therefore the tax due by Jeremy is Total Tax Liability - Tax Payment mande

= $13,418 - $13,200

= $218

Which of the following does not constitute an insurable interest?
Murrr4er [49]

Answer:you make an offer to buy your neighbor's house.

Explanation:

As seen from the aforementioned alternatives which all have insurable interest.Thus they are expantiated;

1)Firstly,a savings and loan company holding a mortgage on your home has an insurable interest on interest of the property on insurance premium.

2)Secondly,your lease makes you liable for fire damage to your rented premises makes for an insurable interest which is in form of mortagee/morgator contract,even if it isn't your property,it makes you liable for an insurable interest.

3)Thirdly,you have custody of a valuable painting when the owner is away also makes you eligible for an insurable interest.Though here as carrier,it still gives the right to an insurable interest courtesy of the fact that it is in your custody.

Finally,you make an offer to buy your neighbor's house doesn't make you eligible for an insurable interest because it's just a matter of a vocal agreement,thus no transaction has been carried out and therefore,no property transferred to your custody either way.

DanielleElmas [232]

Answer:

From the bank statement of $23000 the needs are:

  • cell phone plan = $45
  • rent = $400
  • car insurance = $60
  • Electric bill = $60
  • car payment = $250

A need is something needed for an individual to live a fulfilling life without adverse effect. if a need is not fulfilled it can cause an adverse effect like sickness,death or it might cause a fine or penalty.

Rent is necessary because housing is one of the most important needs of a man without rent plan there would be no proper housing

car insurance: insurance helps to reduce the burden of accidents on the car owner. if he fails to pay his insurance when due. if the car is caught up with eventualities of accident, the insurance company might not respond to him

Electric bill : this is a very important need as well in America. failure to pay the electric bill results to shortage of electricity and electricity is vital to everyday living.

car payment: the regular payment of car loans helps to escape the penalty of late payment hence this is a need.
