Mathematics
1 answer:
Vinvika [58]2 years ago
8 0

Answer:

a) No.

b) Yes.

c) Yes.

Step-by-step explanation:

a) No.

As being without replacement, the probabilities of each color in each draw change depending on the previous draws.

This is best modeled by an hypergeometric distribution.

b) Yes.

As being with replacement, the probabilities for each color is constant.

Also, there are only two colors, so the "success", with probability p, can be associated with the color red, and the "failure", with probability (1-p), with the color blue, for example.

(With more than two colors, it should be "red" and "not red", allowing only two possibilities).

c) Yes.

The answer is binary (Yes or No) and the probabilities are constant, so it can be represented as a binomial experiment.

A right triangle has side 10 and hypotenuse 26. Use the Pythagorean Theorem
alekssr [168]

Answer:

24

Step-by-step explanation:

The Pythagorean Theorem states that a^{2} +b^{2} =c^{2} where a and b are the legs in a right triangle and c is the hypotenuse. Therefore, just substitute the values a = 10 and c = 26 into the equation to get b = 24

Hope this helps :)

Suppose David had $65 to spend on his ticket and some shirts. He already used $32.25 on his ticket and the shirts are $14.50. Ho
DiKsa [7]
We know $65 were spent on his ticket and some shirts.Which he used 32.25 which leaves us  with 27.75 and a shirt cost 14 and 50 cent .

SO you need to divide 27.75 in 14 and 50 cents which is equal to
   
             14 plus 14 equals 28
              75 plus 50 equals 1 and 25 cents

David can buy two shirts 

Hope this helped
