According to the Internal Revenue Service (IRS), the chances of your tax return being audited are about 6 in 1,000 if your incom
Tamiku [17]

Answer:

The probability that none of these taxpayers will be audited by the IRS is 0.8996 or 89.36%

Step-by-step explanation:

According to given:

Probability of being audited for income less than $50,000 = 6/1000 = 0.006

Therefore,

Probability of not being audited for income less than $50,000 = 1 - 0.006 = 0.994

Similary,

Probability of being audited for income more than $100,000 = 49/1000 = 0.049

Therefore,

Probability of not being audited for income more than $100,000 = 1 - 0.049 = 0.951

Now, for the probability of 2 persons with less $50,000 income and 2 persons with more than $100,000 income, to not being audited, we must multiply the probabilities of not being audited of each of the 4 persons.

Therefore,

Probability that none of them is audited = (0.994)(0.994)(0.951)(0.951)

<u>Probability that none of them is audited = 0.8936 = 89.36%</u>

A packing company is doing an inventory of boxes. Their most popular box is display below: 2ft,(3x-5)ft,(2x-1)ft you can use the
Angelina_Jolie [31]

Answer:

The value of x  = 3.

Length = 4 feet and Width = 5 feet

Step-by-step explanation:

Height of the box = 2 ft

Length of the box = (3x-5) ft

Width of the box  = (2x-1) ft

Volume of the box = 40 cubic feet

Now, VOLUME OF CUBE  = LENGTH x WIDTH x HEIGHT

\implies 40 = 2 \times (3x-5) \times (2x-1)\\\implies 20 = 3x(2x-1)) -5 (2x-1) = 6x^2 - 3x -10x +5  = 6x^2 - 13x + 5\\\implies  6x^2 - 13x -15 = 0

Now, solving for the value of x, we get:

6x^2 -13 x - 15  = 6x^2 -18x + 5x - 15 = 0\\\implies6x(x-3) + 5(x-3) = 0\\\implies (x-3)(6x+5) = 0

⇒ Either x-3 = 0, or ( 6x+5) = 0

⇒ Either x  = 3, or x = -5/6

As x = SIDE OF A CUBE ,so it CANNOT be negative.

⇒x  = 3

So, length = (3x-5)  = 3(3) -5 = 9-5 = 4 units

Width = (2x-1) = 2(3) -1  = 5 units

Mama L [17]

Answer:

3c+12

Step-by-step explanation:

Are of rectangle = Length * Width

Given the following data

Length: (c+4) ft

Width: 3 ft

Area of the rectangle = 3 (c+4)

Expand

Area of the rectangle = 3(c) + 3(4)

Area of the rectangle = 3c  + 12

hence the expression in simplest form for the area of the rectangle is 3c+12
