The length of the radius rounded to 2 decimal points is 3.88cm.

In geometry, the area enclosed by a circle of radius r is pie  π[tex]r^2[/tex].

How to round decimals?

Rounding decimals consists of rounding a decimal number to a certain number of decimal places, to save time and help us express really long numbers in shorter terms. There are certain rules to follow when rounding a decimal number. Put simply, if the last digit is less than 5, round the previous digit down. However, if it’s 5 or more than you should round the previous digit up. So, if the number you are about to round is followed by 5, 6, 7, 8, 9 round the number up. And if it is followed by 0, 1, 2, 3, 4 round the number down.

The area of circle is [tex]47.39cm^2[/tex].

Putting it in the formula we get

[tex]47.39cm^2[/tex] = π[tex]r^2[/tex]

[tex]r^2[/tex] = 47.39 / π

r^2 = 15.0847

r = 3.88 cm

Hence the length of the radius rounded to 2 decimal points is 3.88cm.

The given value of x will be found in a right-angled triangle with a base of length 5.2 units and perpendicular of length 3.1 units.

What is a right-angled triangle?

A triangle is said to be a right-angled triangle if one of its inner angles is 90 degrees, or if any one of its angles makes a right angle.

What is the value of x?

(Consider the given figure for reference)

[tex]tan x=\frac{perpendicular}{base}[/tex]

As seen from the figure,

perpendicular = 3.1 units

base = 5.2 units

∴ [tex]tan x =\frac{3.1}{5.2}[/tex]

⇒ [tex]x=tan^{-1} \frac{3.1}{5.2}[/tex]

This is the required value of x.

Therefore, it can concluded that the value of x in a right-angled triangle with a base of length 5.2 units and perpendicular of length 3.1 units is equal to [tex]tan^{-1}\frac{3.1}{5.2}[/tex]

Parallel lines admit equal slopes.

We would bid $0 as the expected value of this game is always negative.

I’ll assume that cash means there will not be fractions of a dollar in the box. Let X be the payout of the box and Y be the amount that we pay for the box after bidding. Then we have

P(X)=1.5X−Y, X≤Y

as ur profit function. Since E[P(X)]=1.5E[X]−Y, we first need to find the expected value of X and Y. Each integer between 0 and 1000 is equally likely to be in the box

(P(X=x)={1}/{1001}

Since we only realize the payout of the box if X≤Y we only need to sum up to Y:

E[X]= x=0∑Y1/1001 = Y(Y+1)/2002

To find the expected value of Y, note that we will pay Y dollars for the box if X≤Y and 0 otherwise. Given a Y, the probability that X≤Y is {Y+1}/{1001}

since each potential value of X shy of Y has probability {1}/{1001}

Then{E}[Y] = {Y(Y+1)}/{1001}

It follows that

[tex]\begin{aligned} \mathbb{E}[P(X)] &= 1.5\mathbb{E}[X] - E[Y] = \frac{1.5Y(Y+1)}{2002} - \frac{Y(Y+1)}{1001} \\ &= \frac{-3Y(Y+1)}{4004} \end{aligned}[/tex]

E[P(X)]=1.5E[X]−E[Y]= 1.5Y(Y+1)/2002  − Y(Y+1)​/1001 = −3Y(Y+1)/4004

which is always negative so we should not bid any amount for the box. Our optimal bid then is $0, with expected payoff $0. Note that my original assumption was the impetus for using a summation; should I have assumed that any value was possible in the box, then we would have to approach X as though it were a continuous variable.

5x - 3(15 - 3x) = 11

5x - 45 + 9x = 11

5x + 9x = 11 + 45

Solving for x is not straight away (we isolate x and divide all terms by its coefficient) as it has coefficient of 3.

Solving for y is easy, we just need to isolate it:

Both of the variables have coefficients that are not factors of the constant term, so the easiest option is to solve the first equation for y.

Notice how Pattern 2 is Pattern 1 with 4 balls added in the bottom row.

Pattern 4 is Pattern 3 with 6 more balls.

Generalizing the trend, we expect Pattern [tex]n[/tex] to be identical to Pattern [tex]n-1[/tex] with [tex]n+2[/tex] more balls.

If [tex]b_n[/tex] is the number of balls in the [tex]n[/tex]-th pattern, then we have the recursive relation

[tex]\begin{cases} b_1 = 6 \\ b_n = b_{n-1} + n + 2 & \text{for } n>1 \end{cases}[/tex]

We can solve this recurrence by substitution. Using the definition of [tex]b_n[/tex], we have

[tex]b_{n-1} = b_{n-2} + (n-1) + 2 \\\\ \implies b_n = (b_{n-2} + (n-1) + 2) + n + 2 \\\\ \implies b_n = b_{n-2} + 2\times2 + \bigg(n + (n-1)\bigg)[/tex]

[tex]b_{n-2} = b_{n-3} + (n-2) + 2 \\\\ \implies b_n = (b_{n-3} + (n-2) + 2) + 2\times 2 + \bigg(n + (n-1)\bigg) \\\\ \implies b_n = b_{n-3} + 3\times2 + \bigg(n + (n-1) + (n-2)\bigg)[/tex]

and so on, down to

[tex]b_n = b_1 + (n-1)\times2 + \bigg(n + (n-1) + (n-2) + \cdots + 2\bigg)[/tex]

Recall that

[tex]\displaystyle \sum_{i=1}^n i = 1 + 2 + 3 + \cdots + n = \frac{n(n+1)}2[/tex]

Then we find

[tex]\displaystyle b_n = 6 + 2(n-1) + \sum_{i=2}^n i[/tex]

[tex]\displaystyle b_n = 2n + 4 + \left(\sum_{i=1}^n i - 1\right)[/tex]
