Compute the permutations and combinations. a farmer buys 2 cows, 3 pigs, and 10 sheep from a seller who has 7 cows, 4 pigs, and 10 sheep. how many choices of animals does he have? 845426

Farmer has 7 choice for cow out of which he choose only 2

4 choice for pig and he choose only 3 pigs

10 choice for sheep and he choose all 10 sheep

Number of ways of choosing cows = 7C2

Number of ways of choosing pigs = 4C3

number of ways of choosing sheep = 10C 10

all these three groups of different animals can make different groups when taken together

That is : 7C2 * 4C3 * 10C10 = 21 * 4 * 1 = 84 ways

i think the answer is b)

step-by-step explanation:

the clues that signal the reader should change tone are the punctuation marks, the grammatical signs. for example, the quotation marks at the beginning of something someone else said literally or the exclamation marks.

the tone of the first line of dialogue until "gettysburg" is a kind tone, a tone of advise. the narrator is trying to the other person in doing something he or she obviously is finding hard to do by giving a piece of advise and bringing up a memory of a successful similar case.

the clue that the reader understand how to read the word "bang" is the exclamation mark. it gives the word a surprise tone, a strong accent.

the best tone for reading the word "bang" is an exciting tone, a surprise one, even a loud one.

the words that should be read with a formal tone are the ones that give factual information. the sentence: mister lincoln couldn't think of anything to say at the gettysburg" gives information about an event and it needs to be read formally, also, when the narrator wants to transmit calmness, a formal and slow tone is needed, because people also transmit messages with the vibrations of our voices and tones.
