Answer:

The answer in 2 decimal places is 335.01 square inches

Step-by-step explanation:

From the problem, the figure has 3 circles inside the rectangle.

The shaded area is the area of the rectangle minus the areas of the 3 circles.

The rectangle has a dimension of 18 in by 30 in.

The circles have radii of 6 in, 9 in and 12 in.

Calculate the areas :

For rectangle :

A=l x w

A=30 x 18=540in^{2}

For Circles :

A=\frac{\pi D^{2} }{4}

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>
