The random variable is given as the number of accountants that posses the CPA certificate. This is based on the fact that N= 15 and P = 0.52.

<h3>What is a random variable?</h3>

A random variable is a variable with an unknown value or a function that gives values to each of the results of an experiment.

<h3>How is the random variable distributed?</h3>

The random variable are distributed binomially.

<h3>What is the probability five of the 15 accountants are CPAs? </h3>

The probability that  five of the 15 accountants are CPAs is 0.0741.

This is derived as follows:

P (x =5) = C^{15} _{5}

= 0.52^{5}

= (1- 0.52)^{15-5}

= 0.07412836549

P(x=5) ≈ 0.0741

<h3>What is the probability seven or eight of the 15 accountants are CPAs? </h3>

P (x = 7 or x = 8) =

P (x = 7) + P (x = 8)

= C^{15} _{7} (0.52)⁷ (o.48)⁸ + C^{15} _{8} (0.52)⁸ (0.48)⁷

= 0.18642 +  0.20196

= 0.388

Monique is a single mom who is raising her three young children on her own. When she files her taxes this year, which tax status
pochemuha

Answer:

C. head of household

Explanation:

Taxation can be defined as the involuntary or compulsory fees levied on individuals or business entities by the government to generate revenues used for funding public institutions and activities.

The different types of tax include the following;

1. Income tax: a tax on the money made by workers in the state. This type of tax is paid by employees with respect to the amount of money they receive as their wages or salary.

2. Property tax: a tax based on the value of a person's home or business. It is mainly taxed on physical assets or properties such as land, building, cars, business, etc.

3. Sales tax: a tax that is a percent of the price of goods sold in retail stores. It is being paid by the consumers (buyers) of finished goods and services and then, transfered to the appropriate authorities by the seller.

In the United States of America, a head of household is a tax filing status for taxpayers that are saddled with the responsibility of paying more than half of the support and housing expenses (costs) of a qualifying person for at least a year. Also, to be eligible to file as a head of household, the taxpayer must be single or unmarried at the end of the year.

Generally, a head of household gets a lower tax rate and higher standard deductions than other taxpayers.

In this scenario, Monique is a single mom who is raising her three young children on her own. When she files her taxes this year, the tax status that will best fit her situation is head of household because she's solely responsible for catering to the needs of her kids.
