The correct answer is c. when Columbus discovered the new world, he used African people to help with labor since the natives were dying off from diseases him and his crew brought with them. Advanced weaponry and others already forming colonies would have made them extra hungry to go to africa and gain as much land as they could as soon as possible.

Suppose that in a casino game the payout is a random variable X . If X is positive, you gain money, if negative, you lose.
Vanyuwa [196]

Answer:

the conditional probability that X = 1 , X = 2 and X = 3 is  0.7333 (73.33%) , 0.25 (25%) and 0.0167 (1.67%) respectively

Step-by-step explanation:

a player wins money when i>0 then defining event W= gain money , then

P(W) = p(i>0) = p(1)+p(2)+p(3)

then the conditional probability can be calculated through the theorem of Bayes

P(X=1/W)= P(X=1 ∩ W)/P(W)

where

P(X=1 ∩ W)= probability that the payout is 1 and earns money

P(X=1 / W)= probability that the payout is 1 given money was earned

then

P(X=1/W)= P(X=1 ∩ W)/P(W) = P(X=1) / P(W) = p(1) /[p(1)+p(2)+p(3)] = 11/40 /(11/40+3/32+1/160 ) = 0.7333 (73.33%)

similarly

P(X=2/W)=p(2) /[p(1)+p(2)+p(3)] = 3/32 /(11/40+3/32+1/160 ) = 0.25 (25%)

P(X=3/W)=p(2) /[p(1)+p(2)+p(3)] = 1/160 /(11/40+3/32+1/160 ) = 0.0167 (1.67%)

Which equals the product of (x – 3)(2x + 1)?<br> 2x² – 7x-3<br> 2x² – 5x-3<br> 3x-2<br> 0 6x²
lina2011 [118]

Answer:

2x² - 5x - 3

Step-by-step explanation:

Given

(x - 3)(2x + 1)

Each term in the second factor is multiplied by each term in the first factor, that is

x(2x + 1) - 3(2x + 1) ← distribute parenthesis

= 2x² + x - 6x - 3 ← collect like terms

= 2x² - 5x - 3

A state's license plates consist of four letters followed by three numerals, and 242 letter arrangements are not allowed. How ma
PolarNik [594]

Answer: There are 456975758 plates that the state can issue.

Step-by-step explanation:

Since we have given that

Number of letters = 4

Number of numerals = 3

And 242 letter arrangements are not allowed.

As we have 26 letters i.e A-Z

and numerals i.e, 0-9

So, the number of plates would be

(26^4)\times 10^3=456976000

So, the restricted letters deducting would be

456976000-242=456975758

Hence, there are 456975758 plates that the state can issue.

Show me how to solve fraction which is greater 5/8 or 2/8
Alexeev081 [22]
First, we converted each fraction into decimal numbers. You do this by dividing the numerator by the denominator for each fraction as illustrated below:
5/8 = 0.632/8 = 0.25
Then, we compared the two decimal numbers to get the answer.
0.25 is not greater than 0.63. Therefore, 2/8 is not greater than 5/8.
