Answer: The standard error (SE) is 0.048.

Step-by-step explanation: The standard error is an error that occur by random chance. In a sample where only some of the population is "experimented", the sample proportion estimates the population proportion.

The formula to find the standard error is:

SE = \sqrt{\frac{p(1-p)}{n} }, where p is the sample proportion and n is the total of the sample of the population.

The sample proportion is

p= \frac{12}{65} = 0.18

So,

SE = \sqrt{\frac{0.18(1-0.18)}{65} }

SE = 0.048

The standard error of this experiment is SE = 0.048

Ross Martin arrived at the following tax information gross salary 56,145 interest earnings 205 dividend income 65 standard deduc
Maksim231197 [3]

The amount that Ross report as taxable income will be $31965.

<h3>What is a taxable income?</h3>

Taxable income refers to the base upon which an income tax system imposes the tax.

In other words, the taxable income is the income over which the government imposed tax. It includes some or all items of income and is reduced by expenses and other deductions.

From the information:

Gross salary = $56,145

Interest earnings = $205

Dividend income = $65

Standard deduction = $12,000

Itemized deductions = $11,250

Adjustments to income = $1,200

The taxable income is given by:

= Gross salary + Interest earnings + Dividend income - Standard deduction - Itemized deductions - Adjustment to income

= 56145 + 205 + 65 - 12000 - 11250 - 1200

= $31965

Does anyone know what 3x+y=15 5x3y=11 is? It has to be answered in desmos.
faust18 [17]

3x + y = 15

5x3y = 11

This is an example of a system of equations.

A system of equations is two or more equations that can be graphed, as the solution that satisfies both equations will be the point where the lines intersect on a graph.

Desmos is a graphing calculator, and thus it allows you to visualize this system.
