Answers
Answer:
Explanation:
Given:
The average hourly wage: 17.94 20.43 21.28 20.41 17.04
To find:
a) sample mean, b) sample standard deviation
To determine the sample mean, we will apply the formula:
[tex]\begin{gathered} Smaple\text{ mean = }\frac{1}{n}\sum_\text{ x} \\ \\ n\text{ = number of dataset = 5} \\ Sample\text{ mean = }\frac{1}{5}(17.94+20.43+21.28+20.41+17.04) \end{gathered}[/tex][tex]\begin{gathered} Sample\text{ mean = }\frac{1}{5}(97.1) \\ \\ Sample\text{ mean = 19.42} \end{gathered}[/tex]To get the median, we need to re-arrange the numbers either in ascending or descending order
In ascending order: 17.04, 17.94, 20.41, 20.43, 21.28
The middle number is 20.41. Hence, the median is 20.41
To determine the sample variance, we will apply the formula:

One number is 8 more than another. Their product is -16.
Answers
Answer:
The two numbers are 4 and -4
Step-by-step explanation:
Turn the words into equations: let's assign one number to be x and the other to be y
x+8=y
x*y=-16
To solve, substitute the value of y in the first equation into y in the second equation.
This gives x*(x+8)=-16
Simplifying gives x^2+8x=-16
x^2+8x+16=0
(x+4)^2=0
x=-4
plug this value of x back into the first equation, -4+8=y, y is 4
Now to make sure the answer is correct: 4 is 8 more than -4, and 4*-4 does equal 16

An aquarium is 26 inches long, 14 inches wide and 24 inches high. The volume of water in the aquarium is 5824 cubic inches. How deep is the water?
Answers
The depth of the water is 16 inches.
What is the depth?The depth represents the vertical distance from the bottom of the aquarium to the top of the water level.
The depth can be found by dividing the volume of the water by the area of the aquarium.
The length of an aquarium = 26 inches
The width of the aquarium = 14 inches
The height of the aquarium = 24 inches
The Capacity of the aquarium = 8,736 cubic inches (26 x 14 x 24)
The volume of water in the aquarium = 5,824 cubic inches
The area of the aquarium = 364 squared inches (26 x 14)
The depth of the water in the aquarium = Volume of Water/Area of aquarium
= 16 inches (5,824/364)
Thus, we can conclude that the water is 16 inches deep.

The value of [tex]m\angle Y[/tex] is [tex]64.25^o[/tex].
In the give question,
Angles [tex]X[/tex] and [tex]Y[/tex] are supplementary.
Angle [tex]X[/tex] measures [tex]115.75^o[/tex] and angle [tex]Y[/tex] measures [tex](m-8)^o[/tex].
We have to find [tex]m\angle Y[/tex].
We firstly learn about supplementary angel.
Angles that add up to [tex]180[/tex] degrees are referred to as supplementary angles.
As given that [tex]X[/tex] and [tex]Y[/tex] are supplementary so the sum of angle [tex]X[/tex] and [tex]Y[/tex] equals to [tex]180^o[/tex].
[tex]\angle X+\angle Y=180^o[/tex]
As we know that [tex]\angle X=115.75^o, \angle Y=(m-8)^o[/tex]
Now putting the value
[tex]115.75^o+(m-8)^o=180^o[/tex]
Now simplifying the expression.
[tex]115.75^o+m^o-8^o=180^o[/tex]
[tex]107.75^o+m^o=180^o[/tex]
Subtract [tex]107.75^o[/tex] on both side
[tex]107.75^o+m^o-107.75^o=180^o-107.75^o[/tex]
[tex]m^o=72.25^o[/tex]
We have to find the value of [tex]m\angle Y[/tex].
The given value of [tex]Y[/tex] is

The approximate volume in milliliters, y, for a volume of x fluid ounces is equal to 29.57 times the value of x. Which table represents this relationship?
Answers
The table which represents the relationship is:
Fluid ounces, x Volume y ( in millimeters)
1 29.57
2 59.14
3 88.71
4 188.28
In mathematics, a relation describes how two distinct sets of information related to one another. If more than two non-empty sets are taken into consideration, a connection between their elements will indicate that more than two sets are being evaluated.
Let y be the volume of fluid x in millimeters.
Now, y is equal to 29.57 times the value of x.
Therefore,
y = 29.57 × x
y = 29.75x
So, when x = 1:
y = 29.75(1) = 29.57
When x = 2,
y = 29.57(2) = 59.14
When x = 3,
y = 29.57(3) = 88.71
When x = 4,
y = 29.57(4) = 118.28
Therefore, the table that represents the relationship is:
Fluid ounces, x Volume y ( in millimeters)

What is a function?
A function from A to B is a rule that assigns to each element of A a unique element of B. A is called the domain of the function and B is called the codomain of the function.
There are different operations on functions like addition, subtraction, multiplication, division and composition of functions.
For f(x) - (-g(x))
-g(x) = -(-2x + 5)
= 2x - 5
f (x) - (-g(x)) = (3x - 7) - (2x - 5)
3x - 7 - 2x + 5
x - 2
For f(x) + g(x)
f(x) + g(x) = (3x - 7) + (-2x + 5)
= 3x - 7 - 2x + 5
= x - 2
So f (x) - (-g(x)) = f(x) + g(x) holds here
Since addition and subtractions can be done on functions,
f (x) - (-g(x)) = f(x) + g(x) holds for every functions.

Percy rides his bike 11.2 miles in 1.4 hours at a constant rate write an equation to represent the proportional relationship between the number of hours Percy rides x and the distance in miles y that he travels
Answers
The proportional relationship representing the situation is given by
y = 8x.
Two numerical sequences, typically experimental data, are said to be proportionate or directly proportional if the ratio of their associated parts is constant, which is known as the coefficient of proportionality of proportionality constant. Two sequences are termed inversely proportionate if the product of their respective elements is constant, also known as the proportionality coefficient.
This concept is usually extended to related changeable quantities, sometimes known as variables. This is not the standard definition of variable in arithmetic, because two separate concepts have the same name for historical reasons.
Given that Percy rides his bicycle for 11.2 miles in 1.4 hours.
Let the constant of proportionality be k.
Therefore the proportional relationship is represented as:
y = k x
Now therefore putting the values we get:
11.2 = k × 1.2
or, k = 8
Hence the relationship will look like :
y = 8 x

The translation function of the form f(x+h)+k.
The value of 'h' controls how much the graph shifts to the left or right
Comparing f(x+h)+k, we get h =4 anf k=-3.
The value of h is positive so the graph shift left by 4 units.
