Answer:

62

Step-by-step explanation:

20% as a decimal is 0.2

For each year get the amount of increase by multiplying the number of rabbits by 0.2

Rabbits in 2013:

25 x 0.2 = 5

25 + 5 = 30 rabbits

Rabbits in 2014:

30 x 0.2 = 6

30 + 6 = 36 rabbits

Rabbits in 2015:

36 x 0.2 = 7.2

36 + 7.2 = 43.2

Rabbits in 2016:

43.2 x 0.2 = 8.64

43.2 + 8.64 = 51.84

Rabbits in 2017:

51.84 x 0.2 = 10.368

51.84 + 10.368 = 62.208

= 62 rabbits

Answer:

16.7%.

Step-by-step explanation:

There are initially 24 + 15 + 8 = 47 pencils in the bag.

Take a pencil out of this bag of 47 pencils. 15 out of the 47 pencils blue. Let A represent the event of getting a blue pencil on the first pick. The probability of getting a blue pencil is:

\displaystyle P(A) = \frac{15}{47}.

There are now 47 - 1 = 46 pencils left in the bag. However, given that the first pencil removed from the bag is blue, the number of red pencils in the bag will still be 24. Take another pencil out of this bag of 46 pencils. Let B represent the event of getting a red pencil on the second pick. The possibility that the second pencil is red given that the first pencil is blue will be:

\displaystyle P(B|A) = \frac{24}{46}.

The question is asking for the possibility that the first pencil is blue and the second pencil is red. That is:

\displaystyle P(A\cap B) = P(A) \cdot P(B|A) = \frac{15}{47}\times \frac{24}{46} = 0.166512 \approx 16.7\%.

4(9x + 7) = x - 4<br><br> ALGEBRA 1!!
tiny-mole [99]

Hey!

-----------------------------------------------

Solution:

4(9x + 7) = x - 4

36x + 28 = x - 4

36x + 28 + 28 = x - 4 + 28

36x = x + (-32)

36x - x = x - (-24) - x

35x = -32

35x/35 = -32/35

x = -32/35

-----------------------------------------------

Answer:

x = -32/35

-----------------------------------------------

Hope This Helped! Good Luck!
