They are all perfect squares because if you took the square root of them you will get a single number. Like the square root of 25 is 5 bc 5(5) is 25
16 is 4 bc 4(4) is 16
9 is 3 bc 3(3) is 9
1 is 1 bc 1(1) is 1
& so on & so forth

Answer:

y=0.25x

We can think of k as an unknown number.

8×_=2.00

12×_=3.00

20×_=5.00

If we divide 2 with 8 we are left with 0.25.

It's the same for the other numbers so we know the constant is 0.25.

When we use the formula y=0.25x with the numbers above, it is correct.

8×0.25=2.00

12×0.25=3.00

20×0.25=5.00

New probabilities that have been found using Bayes' theo- rem are called a. prior probabilities. b. posterior probabilities. c.
Sphinxa [80]

Answer:

b). posterior probabilities.

Step-by-step explanation:

Posterior Probabilities are described as the updated probabilities which are estimated employing the theorem proposed by Baye. According to his theorem, an association is developed between probability and the newly received information. <u>When the previously existing probabilities are amalgamated with this updated information, it gives the existing probabilities' value a correction, update, or revision namely 'posterior probabilities</u>.' Thus, it is the probability that asserts the truth of a hypothesis and hence, <u>option b</u> is the correct answer.
