3 0

Answer:

4 and 20

Step-by-step explanation:

100 times 5 is 500. If we go backwards 500 ÷ 5 = 100.

100 ÷ 5 = 20. 20 ÷ 5 = 4.

An exponential sequence is a sequence that grows more every time. It would get really big really quickly.

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>

In an arithmetic sequence {an}, if a1 = 5 and d = 3, the first 4 terms in the sequence are
noname [10]
A1 represents the first term

d represents the common difference.....and since the common difference is 3, u have to add 3 to each term to find the next term....because with an arithmetic sequence u add to find the next term, whereas, in a geometric sequence u multiply to find the next term

5...first term
5 + 3 = 8...2nd term
8 + 3 = 11...3rd term
11 + 3 = 14...4th term

ur answer is B
