the hint tells you s is sqrt(a)

the question tells you a = 570025

so side = sqrt(570025)

plug that into your calculator to get:

755 feet

21) Each side is 755 in
To do this all you'll need to do is find the root of 570,025, which is 755

22) Each side is 25 in
Again, you'll need to find the square root of 625, which is 25

You read online that the probability of being dealt four‑of‑a‑kind in a five‑card poker hand is 1 / 4165. Explain carefully what

Lapatulllka [165]

Answer:

There is about 4,164/4,165 chances of not getting getting a four of a kind. So, it is extremely unlikely or even borderline impossible in that situation to get a four of a kind.

<u>But in the long run, it can be increased only if you keep drawing. So, the awnser would have to be. D </u>

Step-by-step explanation:

A. It does mean that if you are dealt 4165 five‑card poker hands, one will be four‑of‑a‑kind.

B. It does not mean that all will be four‑of‑a‑kind. The probability is actually saying that only on the 4165 the poker hand will you get a four‑of‑a‑kind, not just on any of the 4165 poker hands.

C. The probability is actually saying that in the long run, with a large number of five‑card poker hands, the fraction in which you will be dealt a four‑of‑a‑kind is 1 / 4165.

D. The chance you will be dealt four‑of‑a‑kind is 1 / 4165 only on the first hand. This chance will then increase with each new hand you are dealt until you eventually win

3x + 2y = 8<br> 5x + 2y = 12

Keith_Richards [23]

Answer:

Step-by-step explanation:

We can solve this in either of two ways. I'll do both.

<u>Mathematically</u>

3x + 2y = 8

5x + 2y = 12

Rewrite either equation to isolate y. I'll use

3x + 2y = 8

2y = 8 - 3x

y = (8-3x)/2

Now use this value of y in the other equation:

5x + 2y = 12

5x + 2((8-3x)/2) = 12

5x + (8 - 3x) = 12

2x = 4

x = 2

Use x=2 to find y:

y = (8-3x)/2

y = (8-3*(2))/2

y = (8-6)/2

y = 1

The point is (2,1)

<u>Graphically</u>

Graph the two equations and find the point they intersect. See attachment.

We obtain the same answer: (2,1)

The center of the circle is (h,k) = (-2,-3)

The radius of the circle is r = 2

The standard form of equation of the circle is

${(x + 2)}^{2} + {(y + 3)}^{2} = 4$

<h3>How to find the center, radius and standrad form of the circle?</h3>

The general form of equation of the circle is

${(x - h)}^{2} + {(y - k)}^{2} = {r}^{2}$

Here, (h,k) means centre of the circle.

r means radius of the circle.

given that coordinate points of centre of circle is (-2,-3).

Hence the (h,k) = (-2,-3)

<h3>How to find the radius of the circle?</h3>

Now to find the radius of the circle

The distance from a circle's centre to its circumference is its radius.

The distance from a circle's centre (-2,-3) to its circumference (0,-3) is its radius.

using the formula, distance between the two points to obtain radius.

$d = \sqrt{(x1 - x2) {}^{2} + {(y1 - y2)}^{2} } \\ r = \sqrt{ {( - 2 - 0)}^{2} + {( - 3 - ( - 3))}^{2} } \\ r = \sqrt{ {( - 2)}^{2} + {( - 3 + 3)}^{2} } \\ r = \sqrt{ {4}^{2} + 0 } \\ r = \sqrt{4} \\ r = 2$
