Mitch plays chess with his aunt every Friday.
He's won 12 matches and lost 3 matches.
What is the experimental probability that Mitch will win the next match?

Answers

Answer 1

The answer is 4/5

What is probability?

Probability is a measure of the likelihood of an event occurring. The probability formula is defined as the possibility of an event happening is equal to the ratio of the number of favorable outcomes and the total number of outcomes. Probability of event to happen P(E) = Number of favorable outcomes/Total Number of outcomes.

Given here: Mitch  won 12 matches and lost 3 matches.

Thus the theoretical probability of him winning the next match is 12/15=4/5

Hence, The answer is 4/5

Breaking down Brown versus Whitman: Example 2 of the chapter 1 discusses an exit poll taken during the 2010 California gubernatorial election. The administrators of the poll also collected demographic data, which allows for further breakdown of the 3889 voters from whom information was collected. Of the 1633 voters registered as Democrats, 91% voted for Brown, with a margin of error of 1.4%. Of the 1206 voters registered as Republicans, 10% voted for Brown, with a margin of error of 1.7%. And of the 1050 Independent voters, 42% voted for Brown, with a margin of error of 3.0%.

Required:
a. Do these results summarize sample data or population data?
b. Identify a descriptive aspect of the results.
c. Identify an inferential aspect of the results.

Answers

Answer:

(A) Population data

(B) The figures

(C) The classification of votes by political party

Step-by-step explanation:

(A) These results summarize population data. The population is the total 3,889 voters from whom information was collected.

The samples would be

- Voters registered as Democrats  (1,633)

- Voters registered as Republicans  (1,206)

- Independent Voters  (1,050)

The total of members in each sample equals the total number of people in the population.

(B) A descriptive aspect of the result is the figures or percentages. They describe how (in percentage) voters penned their votes for Brown and how they penned their votes for Whitman. NOTE: To get the percentage or fraction of those who voted for Whitman, simply subtract the percentage of Brown's supporters from a total of 100%.

(C) An inferential aspect of the results is the classification of votes by different parties (the samples are the different parties involved here). This helps to infer the sources of support for Brown and the sources of support for Whitman.

For example, if the total votes for Brown (in population result analysis) are low, the Republicans are the major reason why!

Answers

Answer:

CP = 17000

Step-by-step explanation:

Given that,

Loss = 10%

Selling price of the watch, SP = $15,300

We need to find the cost price of the watch.

[tex]CP=\dfrac{100}{100-L\%}\times SP\\\\CP=\dfrac{100}{100-10}\times 15300\\\\CP=17000[/tex]

Answer:

I thought it was 3, no wait its 2

Step-by-step explanation:

You are thinking of the Principia Mathematica, written by Alfred North Whitehead and Bertrand Russell. Here is a relevant excerpt:

Picture Below

As you can see, it ends with "From this proposition it will follow, when arithmetical addition has been defined, that 1+1=2." The theorem above, ∗54⋅43, is already a couple of hundred pages into the book (Wikipedia says 370 or so); the later theorem alluded to, that 1+1=2, appears in section ∗102, considerably farther on.

I wrote a blog article a few years ago that discusses this in some detail. You may want to skip the stuff at the beginning about the historical context of Principia Mathematica. But the main point of the article is to explain the theorem above.

The article explains the idiosyncratic and mostly obsolete notation that Principia Mathematica uses, and how the proof works. The theorem here is essentially that if α and β are disjoint sets with exactly one element each, then their union has exactly two elements. This is established based on very slightly simpler theorems, for example that if α is the set that contains x and nothing else, and β is the set that contains y and nothing else, then α∪β contains two elements if and only if x≠y.

The main reason that it takes so long to get to 1+1=2 is that Principia Mathematica starts from almost nothing, and works its way up in very tiny, incremental steps. The work of G. Peano shows that it's not hard to produce a useful set of axioms that can prove 1+1=2 much more easily than Whitehead and Russell do.

Quadratic equation

(x-y)²=x²-2xy+y²​

To prove the equation:

We substitute the value and see if LHS = RHS.

In the LHS,

LHS =  (x-y)²

LHS =  (2-1)²

LHS =  1

In the RHS,

RHS = x²-2xy+y²​

RHS = 4 - 4 + 1

RHS = 1

Answer:

79 + x = 180

x = 101

The sum of all angles of a triangle is 180. So to find the angle you solve 180-(15+25) which equals 140. Then you subtract 39 from 140 to get x. X=101
