Answer:

c. is incorrect

Step-by-step explanation:

2 + 3(x + 3) + x

<em>use the Distributive property a(b + c) = ab + ac</em>

= 2 + 3x + 9 + x     <em>a. is correct</em>

<em>use the Commutative property of addition: a + b = b + a</em>

= 2 + 9 + 3x + x     <em>addition</em>

= (2 + 9) + 3x + x

= 11 + 3x + x        <em>b. is correct</em>

<em>use the </em><em>Distributive property</em><em> a(b + c) = ab + ac</em><em> </em>

<em>not Associative property (a + b) + c = a + (b + c)</em>

= 11 + (3 + 1)x      <em>c. is incorrect</em>

= 11 + 4x

<em>use the Commutative property of addition: a + b = b + a</em>

= 4x + 11

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>
