What is the ones digit in the number 3^20997

Mathematics
1 answer:
Stels [109]4 years ago
3 0

Answer:

7

Step-by-step explanation:

3^0 = 1

3^1 = 3

3^2 = 9

3^3 = 27

3^4 = 81

3^5 = 243

3^6 = 729

3^7 = 2187

3^8 = 6581

===========

You can see that the pattern is beginning to repeat itself.

===================

So all you need do is take 2099 and divide by 3. You must pay attention to the remainder.

2099 / 4 = 524.75

The answer means that you go through the cycle 524 times getting 1,3,9,7,1 as the units digit.

In this case the remainder is 0.75 which is the same as 3/4. The remainder then is 3

If there is no remainder, the ending is a one.

if there is a remainder of 1 the answer is 3

If there is a 2 remainder, the number ends in 9

If there is a 3 remainder, the number ends in 7

And that's your answer.

A spinner has two equal sections, one green and one orange. The spinner is spun three times, resulting in the sample space S = {
Elina [12.6K]

Solution:

As given , Spinner has two equal Sections, one green and one Orange.

When the Spinner is Spun three times

Total Sample Space  S=  {GGG, GGO, GOG, OGG, GOO, OGO, OOG, OOO}

Random variable X is Selected, which represents number of times orange O' is spun, which is given by

X=0,1,2,3

Probability of an event = \frac{\text{Total favorable outcome}}{\text{Total Possible outcome}}

X=0, Probability of Orange(O), in G G G = \frac{1}{8}

X=1, Probability of Orange(O), in G G O , GOG,and O G G, 3 in total =  \frac{1}{8}

X=2, Probability of Orange(O), in G O O , O GO,and O O G, 3 in total =   \frac{1}{8}

X=3, Probability of Orange(O), in O O O, 1 in all= \frac{1}{8}

What is the probabiWhich value cannot represent the probability of an event occurring?
iren2701 [21]

Given problem:

   Which value cannot represent the probability of an event occurring?

      Values:

            \frac{1}{100}    0.29    \frac{85}{100}   Three-halflity

Probability is the likelihood of an event to occur.

For an event that we are sure of occurring, the probability value is 1, and those that cannot occur have a probability value of 0.

  The probability of any event is usually a fraction between 1 and 0.

So we can see that the odd one is the  Three-halflity which is clearly greater than 1.
