1 answer:

6 0

4x^2y(x+2)-x(xy2-3)
(4x^2y)^(x)+(4x^2y)(2)-x^2y^2+3x
4x^3y+8x^2y-x^2y^2+3x
4x^3y-x^2y^2+8x^2y+3x
This was very confusing to solve so sorry if I’m wrong.Also sorry if it’s too hard to write it.

Answer:

740 meters of fence
22,000 square meters

Step-by-step explanation:

Two of the sides total 150 +220 = 370 meters. The other two sides are the same lengths, so the sum of lengths of the four sides is ...

2·370 m = 740 m . . . . . length of fence needed

The area of a parallelogram is the product of base and height.

A = bh = (220 m)(100 m) = 22,000 m^2 . . . . area the fence encloses

Sunny_sXe [5.5K]

15 - x = 2(x + 3)
15 - x = 2x + 6
15 = 3x + 6
9 = 3x
3 = x
x = 3

. The teacher decides that no student can win twice, so she removes the tickets of the first winner before drawing the second wi

kozerog [31]

Answer:

<h2>There is 8% probability of Kitzen winning first and Ava second.</h2>

Step-by-step explanation:

The given table shows that there are 4 students, so there are 4 possible winner in total, but they have different number of tickets.

The total number of tickets is 48, that's the total possible outcomes. Kitzen has a probability of

$P_{Kitzen}=\frac{12}{48}=\frac{1}{4}$

Ava has a probability of

$P_{Ava}=\frac{16}{48}=\frac{1}{3}$

Now, the probability of having one event and the other is

$P=\frac{1}{4} \times \frac{1}{3}=\frac{1}{12} \approx 0.08$

Therefore, there is 8% probability of Kitzen winning first and Ava second.

(Notice that the probaility is not about Kitzen or Ava winning, it's about winning both, that's why the percentage is low)
