We can make the ordered pairs (x, y).
Where x is the number of quarters and y is the number of playable characters.
Now,
A video game was released with 4 playable characters.
This means,

Answer:
[tex]\boxed{21.691} \; feet[/tex]
Step-by-step explanation:
See attached figure
The power cable going south first by 50 feet and then going west by 30 feet form the legs of a right triangle.
The diagonal which is the shortest distance between start and end points can be computed by the Pythagorean theorem
[tex]c^2 = a^2 + b^2[/tex]
where c is the hypotenuse and a, b the other two sides
Plugging in values for a = 50 and b = 30 we get
[tex]c^2 = 50^2 + 30^2\\\\c^2 = 2500 + 900\\\\c^2 = 3400\\\\c = \sqrt{3400}\\\\c = 58.3095 \;feet[/tex]
The cable length if going south and then west will be 50 + 30 = 80 feet
So cable length saved = 80 - 58.3095 = 21.6905
Rounded to 3 decimal places this would be 21.691 feet
Answer:
By using the Pythagorean Theorem, we can calculate that the diagonal of the city block is approximately 58.3 feet long. This means that the power company could save 7.3 feet of powerline cable by running the powerlines across the diagonal of the city block, instead of around the south and west sides.

How do you know if results are practically significant?
Answers
In order to determine the practical significance requires considering both the effect size measures and the context of the study
One way to determine practical significance is by using effect size measures. Effect size is a standardized measurement of the magnitude of a treatment or intervention.
A common equation used to calculate effect size is Cohen's d, which is the difference between the means of two groups divided by the standard deviation.
Another equation used is the odds ratio, which is the ratio of the odds of an event occurring in one group compared to another.
Additionally, it is important to consider the context of the study when evaluating practical significance.

Answers
The system is stable since the magnitude of its impulse response is 0.25, which is a finite number that is less than any M.
The stability of a linear system can be determined by analyzing the magnitude of its impulse response −
|h[n]| ≤ M for some finite M
In this case, the impulse response is h[n] = 0.25nu[n], where nu[n] is the unit step function. Since the magnitude of h[n] is 0.25 for all n, the system is stable since 0.25 is a finite number that is less than any M.

use the general slicing mothod to find the volume of the following solid. The solid with a semicircular base of radius 9 whose cross section is perpendicular to the base and parallel to the diameter are squares. Place the semicircle on the xy-plane so that its diameter is on the x-axis and it is centered on the y-axis. Set up the integral that gives the volume of the solid. Use increasing limits of integration.
Answers
The volume of the solid is approximately equal to 441.75 π cubic units.
The volume of the solid can be found using the disk method of integration. To set up the integral, consider a disk of height 'h' and radius 'r' at position y. The volume of this disk is given by πr^2h, and the radius 'r' is equal to 9 - y. Therefore, the volume of the solid is given by the following triple integral:
[tex]V = \int\{\pi(9 - y)^2dy} \int\,dh \int\,dx[/tex]
Where the limits of integration are:
For x: 0 to 9 (since the square cross-section has side length of 9)For h: 0 to x (since the height of the disk cannot be greater than the distance from the xy-plane)For y: 0 to 9 (since the radius of the semicircle is 9)So, the final expression for the volume is:
[tex]V = \int\limits^{9}_{y=0} \int\limits^{x}_{h=0} \int\limits^{9}_{x=0} \pi (9 - y)^2 dh dx dy[/tex]
Evaluating the integral gives:
[tex]V = \pi \int\limits_{y=0}^{9} (9 - y)^2dy \int\limits_{h=0}^{x} dh \int\limits_{x=0}^{9} dx[/tex]
[tex]= \pi \int\limits_{y=0}^{9} (81 - 18y + y^2)dy \int\limits_{h=0}^{x} dh \int\limits_{x=0}^{9} dx[/tex]
[tex]= \pi \int\limits_{y=0}^{9} (81 - 18y + y^2)dy (x^2/2) dx[/tex]
[tex]= \pi /2 \int\limits_{y=0}^{9} (81 - 18y + y^2)dy (x^2) dx[/tex]

(a) For an uninformative prior, do we need a large or small value for σ0? [2]
(b) We want the prior probability P(|θ| ≤ A+10) to be 0.95, where A is the third-to-last digit
of your ID number. What value for σ0 should we choose? [4]
(c) A colleague prefers a Cauchy distribution as a prior. What is a possible reason for this
preference?
Answers
the data y = (y1,..., yn) are a sample from a normal distribution with unknown mean θ and known standard deviation σ = 2. Our prior distribution p(θ) is normal with mean 0 and standard deviation σ0.
y > 3/2, α² → 0 ⇒p(Ф=2Iy) → 1 y < 3/2, α² → 0 ⇒p(Ф=1Iy) → 1
We have two cases for Ф,
1. Ф=1; it implies that Pr(Ф=1)=0.5, while y~N(1,α²)
2. Ф=2; it implies that Pr(Ф=2)=0.5, while y~N(2,α²)
Now,
For 1st case of α=2,
We have marginal probability density formula
p(y)=∑p(yIФ)p(Ф)
=p(yIФ=1)p(Ф=1)+p(yIФ=2)p(Ф=2)
=N(yI1,2²)(1/2)+N(yI2,2²)(1/2)
=(1/2)[N(yI1,2²)+N(yI2,2²)]
Now.
For Pr(Ф=1Iy=1) at α=2
We have,
=p(Ф=1Iy=1)
=[p(y=1,Ф=1)]/[p(y=1)]
=[p(y=1IФ=1)p(Ф=1)]/[p(y=1)]
={(1/)exp[(-1/(2*2²))(1-1)²(1/2)]}/{(1/)(1/2)[exp[(-1/(2*2²))(1-1)²]+exp[(-1/(2*2²))(1-2)²]}
=0.53 Answer
Now, to describe the changes in shape of Ф when α is increased and decreased deviation
The formula for posterioir density is p(ФIy)=p(yIФ)p(Ф)/p(y)
=exp[(-1/(2α²)(y-Ф)²]/{exp[(-1/(2α²)(y-1)²]+exp[(-1/(2α²))(y-2)²]}
Now at Ф=1 and solving the equation, we get
p(Ф=1Iy)=1 / {1+exp[(2y-3)/2α²]}
Similarly at Ф=1 and solving the equation, we get
p(Ф=2Iy)=1 / {1+exp[(2y-3)/2α²]}
Conclusion:
α² → ∞ ⇒p(ФIy) → p(Ф) = 1/2
α² → 0 ⇒ two cases
y > 3/2, α² → 0 ⇒p(Ф=2Iy) → 1
y < 3/2, α² → 0 ⇒p(Ф=1Iy) → 1

The solutions to the equation |4 − 2x| + 6 = 18, in order from least to greatest, are:
x = -4 or x = 8
What is inequality?
A solution for an inequality in x is a number such that when we substitute that number for x we have a true statement. So, 4 is a solution for example 1, while 8 is not. The solution set of an inequality is the set of all solutions.
We can solve this absolute value equation by first isolating the absolute value term on one side of the equation and then solving for both possible cases. Here are the steps:
|4 − 2x| + 6 = 18
|4 − 2x| = 12 (subtract 6 from both sides)
Now we have an absolute value equation with no constant term. We can split this equation into two cases: one where the expression inside the absolute value is positive, and one where it is negative. For each case, we can solve for x:
Case 1: 4 - 2x > 0
If 4 - 2x is positive, then we can drop the absolute value bars and write:
4 - 2x = 12
-2x = 8
x = -4
So one solution is x = -4.
Case 2: 4 - 2x < 0
If 4 - 2x is negative, then we must flip the inequality when dropping the absolute value bars:
-(4 - 2x) = 12
-4 + 2x = 12
2x = 16
x = 8
So the other solution is x = 8.
Therefore, the solutions to the equation |4 − 2x| + 6 = 18, in order from least to greatest, are:

Answer:
f(x) = 100 (3)^x <===> C
f(x) = 100 (3.5)^x <===> B
f(x) = 100 (4)^x <===> A
Step-by-step explanation:
Since the base of each of the exponential functions is the same, the higher the base, the higher up the graph will be with respect to another base with a lower value
This can be easily determined by choosing a specific value for x for each equation and seeing what the f(x) value is
Let's choose x = 2
For f(x) = 100 (3)^x, at x = 2 we get f(2) = 100(3)^2 = 100 x 9 = 900
For f(x) = 100 (3.5)^x, at x = 2 we get f(2) = 100(3.5)^2 = 100 x 12.25 = 12.25
For f(x) = 100 (4)^x, at x = 2 we get f(2) = 100(4)^2 = 100 x 16 = 1600
So for a specific value of x, the higher the base, the higher the graph is relative to the x-axis
So the matches are:
f(x) = 100 (3)^x <===> C
f(x) = 100 (3.5)^x <===> B
f(x) = 100 (4)^x <===> A

The simplified value of the expression - 10 + 1 + (- 6). - (15 - 17 - 35) is 20.
What is PEMDAS rule?PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.
Given, An expression - 10 + 1 + (- 6). - (15 - 17 - 35).
Now, If any of the arithmetic operations are not present we'll simply do the next and we'll also distribute the negative and positive signs.
- 10 + 1 + (- 6). - (15 - 17 - 35).
= - 10 + 1 - 6 - 15 + 15 + 35.
= - 9 - 21 + 50.
= - 30 + 50.
= 20.
