Answers
Solution :
a). \($\text{Set up hypothesis}$\)
\($\text{Null hypothesis}$\) : There is no significance between them.
\($H_0:\mu_1=\mu_2$\)
\($\text{Alternate hypothesis}$\) : There is significance between them.

Which function has the same range as \(f(x)= - 2\sqrt{x} =-3 + 8\\\)
Answers
Both g(x) = 5 - x² and h(x) = \(5 - e^(6-^x^)\)have the same range as f(x) = -2√(x) - 3 + 8, which is (-∞, 5].
To determine which function has the same range as f(x) = -2√(x) - 3 + 8, we need to first find the range of f(x).
The square root function √(x) takes non-negative values as input and gives non-negative outputs, so the expression -2√(x) will always be non-positive. Therefore, the range of f(x) will be all real numbers less than or equal to -3 + 8, which is 5.
In other words, the range of f(x) is (-∞, 5].
So, we need to find a function whose range is also (-∞, 5]. One possible function is g(x) = 5 - x². We can see that when x is zero, g(x) is at its maximum value of 5, and as we increase or decrease x, g(x) will decrease, eventually approaching negative infinity.
Another possible function is h(x) = 5 - e^(-x). When x is negative infinity, e^(-x) is approaching positive infinity, so h(x) is approaching 0. As we increase x, e^(-x) is approaching zero, so h(x) is approaching 5.

The original figure is formed by the following vertices: \(A(x,y) = (6, 9)\), \(B(x,y) = (7.5, 9)\), \(C(x,y) = (7.5, 6)\), \(D(x,y) = (9,6)\), \(E(x,y) = (9, 4.5)\) y \(F(x,y) = (6, 4.5)\). The image is found by the following transformation:
\(P'(x,y) = O(x,y)+k\cdot [P(x,y)-O(x,y)]\) (1)
Where:
\(O(x,y)\) - Centre of dilation.\(P(x,y)\) - Original point.\(P'(x,y)\) - Resulting point.\(k\) - Dilation factor.If we know that \(O(x,y) = (0,3)\) and \(k = \frac{1}{3}\), then the resulting points of the figure are, respectively:
\(A'(x,y) = (0,3) + \frac{1}{3}\cdot [(6,9)-(0,3)]\)
\(A'(x,y) = (0,3) + \frac{1}{3}\cdot (6,6)\)
\(A'(x,y) = (0,3) +(2,2)\)
\(A'(x,y) = (2,5)\)
\(B'(x,y) = (0,3) + \frac{1}{3}\cdot [(7.5, 9)-(0,3)]\)
\(B'(x,y) = (0,3) +\frac{1}{3}\cdot (7.5, 6)\)

\(B'(x,y) = (2.5, 5)\)
\(C'(x,y) = (0,3) + \frac{1}{3}\cdot [(7.5,6)-(0,3)]\)
\(C'(x,y) = (0,3) +\frac{1}{3}\cdot (7.5, 3)\)
\(C'(x,y) = (0,3) +(2.5, 1)\)
\(C'(x,y) = (2.5, 4)\)
\(D'(x,y) = (0,3) + \frac{1}{3}\cdot [(9,6)-(0,3)]\)
\(D'(x,y) = (0,3)+\frac{1}{3}\cdot (9, 3)\)
\(D'(x,y) = (0,3) +(3, 1)\)
\(D'(x,y) = (3, 4)\)
\(E'(x,y) = (0,3)+\frac{1}{3}\cdot [(9, 4.5)-(0,3)]\)
\(E'(x,y) = (0,3) + \frac{1}{3} \cdot (9,1.5)\)
\(E'(x,y) = (0,3) + (3, 0.5)\)
\(E'(x,y) = (3, 3.5)\)
\(F'(x,y) = (0,3) + \frac{1}{3}\cdot [(6, 4.5)-(0,3)]\)

How many cubes are needed to fill the rectangular prism?
Enter your answer in the box.
To fill the rectangular prism, _____ cubes are neede.
Answers
Based on the given information, to fill the rectangular prism 8,320 cubes are needed.
What is a rectangular prism?
A rectangular prism is a three-dimensional shape with six rectangular faces. It is also known as a rectangular parallelepiped or a rectangular cuboid.
The volume of the rectangular prism is given by multiplying its length, width, and height:
Volume of the rectangular prism = length x width x height
= 20 in. x 2 in. x (13/4) in.
= 130 cubic inches
Each cube has an edge length of 1/4 inch, so its volume is (1/4)^3 = 1/64 cubic inches.
To fill the rectangular prism, we need to divide its volume by the volume of each cube:
Number of cubes = Volume of the rectangular prism / Volume of each cube
= 130 / (1/64)
= 8,320
Therefore, to fill the rectangular prism, 8,320 cubes are needed.

Suppose that the average bill for the drive through of 24 customers at Burger Palace is $14.30. It is known that the population standard deviation is σ=2.30. Estimate the true mean bill for a customer at Burger Palace with 95% confidence.
Answers
The standard deviation is a measure of a collection of values' variance or dispersion. The true mean bill for a customer at Burger Palace with 95% confidence is $13.38.
What is a standard deviation?The standard deviation is a measure of a collection of values' variance or dispersion. A low standard deviation implies that the values are close to the set's mean, whereas a high standard deviation shows that the values are spread out over a larger range.
Given that the Sample mean (\(\overline x\)) is $14.30, the Sample size(n) is 24 customers, the Standard deviation(σ) is 2.30, while for a 95% confidence interval the Z-score is 1.960. Therefore, the true mean can be written as,
\(Z = \dfrac{\overline x- \mu}{\frac{\sigma}{\sqrt n}}\\\\\\1.960 = \dfrac{14.30-\mu}{\frac{2.30}{\sqrt{24}}}\\\\\\1.960 = \dfrac{14.3-\mu}{0.47}\)
μ = 13.3788 ≈ 13.38
Hence, the true mean bill for a customer at Burger Palace with 95% confidence is $13.38.

c = πd
This depends on knowing the radius (r) or diameter (d).
For example, let's calculate it manually.

The solution to given linear inequality, 6(x1.5) + 30 < 48, is x < 2
Solving linear inequalitiesFrom the question, we are to solve the given linear inequality
The given linear inequality is
6(x1.5) + 30 < 48
First, we will write this inequality properly.
The inequality can be properly written as
6(1.5x) + 30 < 48
Now, we will solve the linear inequality
6(1.5x) + 30 < 48
Subtract 30 from both sides of the equation
6(1.5x) + 30 - 30 < 48 - 30
6(1.5x) < 18
Divide both sides of the inequality by 6
6(1.5x)/6 < 18/6
(1.5x) < 3
1.5x < 3

length to be 1.2 times the width. Determine the restrictions on the width so that the dimensions of the garden will meet the required area. Give exact
values and the approximated values to the nearest tenth of a yard.
Answers
The restrictions on the width is that it must be between 14.1 yards and 17.3 yards
How to determine the restrictions on the widthFrom the question, we have the following parameters that can be used in our computation:
Area = between 240 yd² and 360 yd²
Also, we have
Length = 1.2 times the width
This means that
l = 1.2w
The area is then calculated as
Area = lw
So, we have
Area = 1.2w²
This means that
240 < 1.2w² < 360
Divide through by 1.2
200 < w² < 300
Take the square roots
14.14 < w < 17.32
Approximate
14.1 < w < 17.3
Hence, the width must be between 14.1 yards and 17.3 yards
