In the Reflecting Ball Game, a ball can be launched from points 1, 2, 3, 4, 5 or 6 in the direction shown. When a ball hits a side of rectangle $ABCD$, it bounces at a $90^{\circ}$ angle back into the playing field. The path of the ball ends when it hits corner point $A$, $B$, $C$, or $D$. The path for starting point 5 is shown in the diagram. Each of the $15$ non-overlapping squares of the playing field has an area of $2$ square centimeters. What is the length of the longest possible path for a ball launched from a starting point?
The maximum is 12 diagonals or a length of 12 × 2√2 =24√2 centimeters.
How to solveNote that the ball moves only on the diagonals of the 15 non-overlapping squares. Thus we must find the path that traverses the most diagonals.
From point 1, the path traverses 6 diagonals before ending up at D.
From point 2, the path traverses 12 diagonals before ending up at A (incidentally, it passes through point 5 in the specified direction so we do not need to check point 5).
From point 3, the path traverses 3 diagonals before ending up at B.
From point 4, the path traverses 9 diagonals before ending up at C.
From point 6, the path traverses 10 diagonals before ending up at D.
Thus the maximum is 12 diagonals, or a length of 12 × 2√2 =24√2 centimeters.

If a < b, what can you say about the locations of a and b on the number line?
There is not enough information given.
a is to the right of b.
a is to the left of b.
a and b are the same distance away from 0.
If a < b, we can say that b is to the right of a on the number line. In other words, a is to the left of b.
What exactly is the number line?A number line is a horizontal line with evenly spaced number increments. The numbers on the line will determine how the number on the line can be answered. The question that goes with the number determines how it will be used, such as plotting a point.
If a b, then b is to the right of a on the number line. To put it another way, an is to the left of b.
This is because the number line depicts the order of real numbers, with smaller numbers to the left and larger numbers to the right. Because an is less than b, it is a smaller number and must be to the left of b on the number line.

Write the function in vertex form for this parabola focus=(3, 2.5)
The equation of parabola in vertex form is [tex]$$\boxed{x^2 - 6x + 9 = 0}$$[/tex]
How to find the equation of parabola?To write the equation of a parabola in vertex form, we use the following formula:
[tex]$$(x-h)^2=4p(y-k)$$[/tex]
where (h,k) is the vertex and p is the distance between the focus and the vertex.
Given that the focus of the parabola is at (3, 2.5), we can determine that the vertex of the parabola is also at (3, 2.5). Let's substitute these values into the formula:
[tex]$$(x-3)^2=4p(y-2.5)$$[/tex]
To find the value of p, we need to use the fact that the distance between the focus and vertex is p. The distance formula is:
[tex]$$d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}$$[/tex]
Substituting the values we know:
[tex]$$\begin{aligned} d &= \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \ &= \sqrt{(3 - 3)^2 + (2.5 - 2.5)^2} \ &= 0 \end{aligned}$$[/tex]
Since d = 0, we know that p = 0 and the equation simplifies to:
[tex]$$(x-3)^2=0$$[/tex]
Expanding the left side:
[tex]$$x^2 - 6x + 9 = 0$$[/tex]
So the equation of the parabola in vertex form is:
[tex]$$\boxed{(x-3)^2=4 \cdot 0 (y-2.5)}$$[/tex]
Or

The thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.
a) Determine the proportion of flanges that exceeds 1.01 millimeters.
b) What thickness is exceeded by 90% of the flanges?c) Determine the mean and variance of flange thickness.
Mean = (millimeters)
variance = (millimeters2)
With the thickness of a flange on an aircraft component is uniformly distributed between 0.95 and 1.05 millimeters.
a) 40% of the flanges exceeds 1.01 millimeters.
b) 1.04 millimeters is the thickness that is exceeded by 90% of the flanges.
c) The mean of flange thickness is 1 millimeters and the variance of flange thickness is 0.01 millimeters^2.
a) To determine the proportion of flanges that exceeds 1.01 millimeters, we need to find the area under the probability density function (pdf) of the thickness that is greater than 1.01 millimeters.
Let's call the random variable X representing the thickness of the flange. The pdf of X is uniform, so it has constant value over the interval [0.95, 1.05]. Therefore, the proportion of flanges that exceeds 1.01 millimeters can be found as follows:
P(X > 1.01) = (1.05 - 1.01) / (1.05 - 0.95) = (1.05 - 1.01) / 0.1 = 0.04 / 0.1 = 0.4
So, 40% of the flanges exceed 1.01 millimeters.
b) To find the thickness that is exceeded by 90% of the flanges, we need to solve for X in the following equation:
P(X > X) = 0.9
Substituting the values for the pdf, we get:
(X - 0.95) / (1.05 - 0.95) = 0.9
Solving for X, we get:
X = 0.95 + 0.9 * (1.05 - 0.95) = 0.95 + 0.9 * 0.1 = 0.95 + 0.09 = 1.04
So, 1.04 millimeters is the thickness that is exceeded by 90% of the flanges.
c) The mean of X can be calculated as follows:
Mean = (0.95 + 1.05) / 2 = 1
The variance of X can be calculated as follows:
Variance = (1.05 - 0.95)^2 / 12 = 0.01
So, the mean and variance of flange thickness are:
Mean = 1 millimeters
Variance = 0.01 millimeters^2

Suppose each of the apples weighs about 5 ounces. Can you buy 24 apples for $9? Explain
Yes You can buy 24 apples for $0.125 per pound. This price will not available except in festival or discounts sale.
what are ounces ?
An ounce is a unit of weight or mass commonly used in the United States and other countries. It is usually abbreviated as oz. One ounce is equal to 1/16th of a pound or approximately 28.35 grams. Ounces are often used to measure small quantities of food or ingredients in recipes, as well as for measuring the weight of small objects.
According to the question:
To determine whether you can buy 24 apples for $9, we need to find the cost per apple.
If 24 apples cost $9, then the cost per apple is:
$9 / 24 apples = $0.375 per apple
Since each apple weighs about 5 ounces, there are about 3 apples per pound:
16 ounces / 5 ounces per apple ≈ 3.2 apples per pound
Therefore, the cost per pound of apples is:
$0.375 per apple / 3 apples per pound = $0.125 per pound

True or False: A simple random sample is a sample of n observations that has the same probability of being selected from the population as any other sample of n observations.
True. A simple random sample is a type of sampling method that is used to select a subset of observations from a larger population.
The key characteristic of a simple random sample is that each observation in the population has an equal probability of being selected to be part of the sample.
Mathematically, this can be expressed as follows: Let N be the population size, and let n be the sample size. Then, the probability of any specific sample of n observations being selected from the population is given by the formula:
P(Sample) = (n!/N!)/(N-n)!
where n! represents the factorial of n (n factorial), and (N-n)! represents the factorial of N-n.
This means that if we were to draw multiple simple random samples of the same size from the same population, each sample would have an equal probability of being selected.
In conclusion, a simple random sample is a method of selecting a subset of observations from a population that ensures that each observation has an equal probability of being selected, and that each sample has an equal probability of being selected.

The value of f(1) will be 45.
What is the function?A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.
Given a function f(n) = 45.(4/5)ⁿ⁻¹
To calculate the value of f(1) we will substitute the value of the n by 1.
f(1) = 45.(4/5)¹⁻¹
f(1) = 45.(4/5)⁰
f(1) = 45
To calculate the value of f(n -1) we will substitute the value of the n by
n - 1.
f(n -1) = 45.(4/5)ⁿ⁻¹⁻¹
that can also be written as, from the rule of power
f(n -1) = (45.(4/5)ⁿ⁻¹)/4/5
f(n -1) = (45.(4/5)ⁿ⁻¹) * 5/4
f(n -1) = f(n) * 5/4
so,
f(n) = f(n-1) * 4/5
Therefore, the value of f(1) will be 45, and the value of f(n) = f(n-11)*4/5.
