Answer:

1/5525 ≈ 0.018%

Step-by-step explanation:

There are 4 kings in a standard deck of 52 cards.

The probability that the first card is a king is 4/52.

The probability that the second card is also a king is 3/51 (the first king isn't replaced, so there's one less king and one less card in the deck).

The probability that the third card is a king is 2/50.

The probability of choosing 3 king cards is therefore:

P = (4/52) (3/51) (2/50)

P = (1/13) (1/17) (1/25)

P = 1/5525

P ≈ 0.018%

Cuantos múltiplos de 9 hay entre 60 y 100
slega [8]

Answer: 5 multiples of 9

Step-by-step explanation:

First take the difference between 100 and 60.

100-60=40

Then divide the difference by 9.

40/9=4.44

4.44 rounded up is 5 ==> 5 multiples of 9

Primero toma la diferencia entre 100 y 60.

100-60=40

Luego divide la diferencia entre 9.

40/9=4,44

4.44 redondeado es 5 ==> 5 múltiplos de 9

Using the given table of an exponential function, determine the growth/decay factor as well as the rate of increase/decrease. Ty
Harlamova29_29 [7]

Answer:

0.7 is the growth factor

0.3 is the growth rate

Step-by-step explanation:

Here, we want to get the growth rate and the growth factor

Let us consider the general form of an exponential equation

That will be;

y = a(1 + r)^n

The growth rate is r

while the growth factor is the term (1 + r)

From the given exponential function;

-0.3 is the rate of increase

Growth rate is 1-0.3 = 0.7
