Answer:

[tex]P(r)=65536(\frac{1}{2})^{r}[/tex]

Step-by-step explanation:

Since the total number of participants in the tournament is 65,536 people, and the exponential decay is [tex]\frac{1}{2}[/tex], using [tex]P(r)[/tex] as the representative of the number of people after [tex]r[/tex] rounds, the formula to represent the model would be [tex]P(r)=65536(\frac{1}{2})^{r}[/tex].

Answer:

[tex]p_r = 65\ 536 \div 2^r = 65\ 536 \div 2^-^r = 2^{16-r}; r\ \in \{0,1,2,3...16\}[/tex]

Step-by-step explanation:

Pet peeve of mine: let's call it [tex]p_r[/tex]  (read p sub r)since it's a representation over the natural numbers and not over [tex]\mathbb{R}[/tex].

Old man yelling at clouds moment gone, we know that the number of people gets halved every time so

At round 0, we do not halve, so [tex]p_0 = 65\ 536\div 1[/tex]

At round 1, we halve once, so [tex]p_1 = 65\ 536\div 2[/tex]

At round 2, we halve twice, so [tex]p_2 = 65\ 536\div 4 = 65\ 536\div 2^2[/tex]

At round 3, we halve three times, so [tex]p_3 = 65\ 536\div 8 = 65\ 536\div 2^3[/tex]

...

At round k, we halved k times, so [tex]p_k = 65\ 536 \div 2^k[/tex]

...

At round 16 we [tex]2^1^6 =65\ 536[/tex] so we have a winner.

That allows us to write a formula. I personally find the last one to be the neater, but any of the three is formally correct.

[tex]p_r = 65\ 536 \div 2^r = 65\ 536 \div 2^-^r = 2^{16-r}; r\ \in \{0,1,2,3...16\}[/tex]

Answer:

150

Step-by-step explanation:

this first side is 6 by 5, (6 x 5 = 30) and 4 sides have these measurements so (30 x 4 this = 120) to find the surface area of all these sides.

The second type of side is 3 by 5, (3 x 5 = 15) and 2 sides have these measurements so we have to do (15 x 2 = 30) to find the surface area of all these sides.

Now that we have all the surface area of all the sides we have to add them up (30 + 120) the surface area of the rectangular prism is 150.

Can you mark brainlyist?

Answer:

1,200 packets of tea

Step-by-step explanation:

1. First, convert 600 kilograms into grams.

1 kilogram = 1,000 grams

So,

600 kilograms = 600,000 grams.

Now divide the previous value by 500.

[tex]\frac{600,000 g}{500 g} = 1,200[/tex]

Answer:

Dimension 1 = 12 x 8

Dimension 2 = 14 x 6

Chris should choose Dimension 1

Step-by-step explanation:

Perimeter of a rectangle = 2 × width + 2 × length

                                         = 2(width + length)

Given:

⇒ 40 = 2(width + length)

⇒ width + length = 20 m

Therefore, possible dimensions:

We need to calculate the area of both choices.  The choice with the greatest area will allow the most vegetables to be planted.

Therefore, Chris should choose Dimension 1 (12 x 8).

The value of x is not one of the options listed. However, if we round to the nearest tenth, we get x = 2.9, which is closer to option B, 2.5. But none of the options match the exact value of x.

What is an arithmetic operation?

Arithmetic operations is a branch of mathematics, that involves the study of numbers, the operation of numbers that are useful in all the other branches of mathematics. It basically comprises operations such as Addition, Subtraction, Multiplication, and Division.

To solve for x, we need to isolate it on one side of the equation.

We can isolate x by dividing both sides of the equation by 20:

x(20) / 20 = 58 / 20

Simplifying:

x = 2.9

Therefore, the value of x is not one of the options listed. However, if we round to the nearest tenth, we get x = 2.9, which is closer to option B, 2.5. But none of the options match the exact value of x.

Using it's concept, it is found that there is a 0.4901 = 49.01% probability that the person responded "same" or "better".

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Researching the problem on the internet, it is found that 424 + 566 = 990 out of 2020 respondants said that they were doing the same or better, hence:

p = 990/2020 = 0.4901

There is no solution for the given function [tex]\rm f(x) = -0.5|2x+2|+1[/tex] when f(x) = 6 option fourth is correct.

It is given that the function  [tex]\rm f(x) = -0.5|2x+2|+1[/tex]

It is required to find the values of x when f(x) = 6

It is defined as a special type of relationship and they have a predefined domain and range according to the function.

We have a function:

[tex]\rm f(x) = -0.5|2x+2|+1[/tex]

And f(x) = 6

Putting the value of f(x) in the above equation, we get:

[tex]\rm 6 = -0.5|2x+2|+1[/tex]   or

[tex]\rm -0.5|2x+2|+1= 6\\\\\rm -0.5|2x+2|= 6-1\\\\\rm -0.5|2x+2|+5\\\\\rm |2x+2|= \frac{5}{-0.5} \\\\\rm |2x+2|= -10[/tex]

Here we can see the mod function values is negative which is not possible, hence there is no solution for the above equation for any 'x'

Step-by-step explanation:

Replace the x by 2 and evaluate:

f(2) = 5(2 - 3) + 17

= -5 + 17

= 12.

The value of function f (2) is, 12

We have to give that,

The function is defined as,

f (x) = 5 (x - 3) + 17

Substitute x = 2 in the above function,

f (x) = 5 (x - 3) + 17

f (2) = 5 (2 - 3) + 17

f (2) = 5 × - 1 + 17

Answer:

[tex]y=-x+3[/tex]

Step-by-step explanation:

Let's start by defining what slope-intercept form is. Slope-intercept form is:

y=mx+b

Where...

"y" = y-coordinate of any point on the line

"m" = slope of the line

"x" = x-coordinate of any point on the line

"b" = y-intercept (where the line intercepts the y-axis)

Let's start by finding the y-intercept. As stated above, the y-intercept is where the line intercepts the y-axis. Looking at the graph, we can tell that in this case, it is (0, 3).

Note that the y-intercept (b) is represented by ONLY the y-value, which in this case is 3.

Now, let's find the slope. Start by taking ANY two points on the line. Let's use (0, 3) and (1, 2).

The formula for slope is:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]y_1, y_2:$ Values for the two y-coordinates\\x_1, x_2:$ Values for the two x-coordinates[/tex]

Substitute the given points into the equation:

[tex]m=\frac{2-3}{1-0}=\frac{-1}{1}=-1[/tex]

The slope is -1.

Finally, we substitute our slope and y-intercept back into the equation and get:

[tex]y=-x+3[/tex]

Answer:
