For Kimberly's P.E final she must either walk or run at least 5 miles this week. She knows it would take her 15 minutes to run a mile and 40 minutes to walk a mile, Kimberly only has 6 hours in which she must accomplish this final. Write an equation that represents Kimberly's P.E final for both walking and running. Define all variables
The equation for Kilberly's running or walking will be R+4w ≤ 6.
What is inequality?When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.
Given that For Kimberly's P.E final she must either walk or run at least 5 miles this week. She knows it would take her 15 minutes to run a mile and 40 minutes to walk a mile, Kimberly only has 6 hours in which she must accomplish this final.
Let the running is represented by 'R' and walking by 'w". The equation will be written as below:-
R + 4W ≤ 6
Put the running and walking times in the equation above.
15 + ( 4 x 40 ) ≤ 6
175 minute ≤ 6 x 60
175 minutes ≤ 360 minutes.
Therefore, Kimberly covers the distance in less than 6 hours.

1-4: Literal Equations Once a large pink ribbon, the sign of the fight against breast cancer, was erected out of pink post-it notes on a billboard. If the area of the rectangular billboard covered by the ribbon was approximat 3360 square feet, and the width of the billboard was approximately 56 feet, what was the height of this billboard?
If the area of the rectangular billboard covered by the ribbon was approximately 3360 square feet, and the width of the billboard was approximately 56 feet, the height of the billboard would be 71.25 feet.
What is area?The exact measurement that helps to express the size of a region on a plane or curved surface is thus called as area.
Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
In mathematical terminology, area can be defined as the total space that is taken up by a flat (2-D) surface or shape of a present object.
Here the area of the billboard = 3360 sq feet
Width of the billboard = 56 feet
We know that
area of the billboard = Height of the billboard x Width of the billboard
⇒ Height of the billboard = [Area of the billboard] / [Width of the billboard]
⇒ Height of the billboard= 3360/56
⇒ Height of the billboard = 71.25 feet

I need assistance on scatter plots. Please see the attached question
From the scatter plot of sales of Ceiling Fan in relation to Temperature.
(a) We are asked to characterized the money spent on Ceiling Fan to Temperature.
The relationship between the money spent on Ceiling Fan and Temperature is positive correlation.
When the y variable tends to increase as the x variable increases, we say there is a positive correlation. Which we can see in the scatter plot in the question.
(b) using the function y = 20x + 0, we are to find the predicted amount of sales if temperature is 21 degrees Celsius.
With the function:
y = 20x + 0
When Temperature is 21 degrees that means x = 21
So let's input x = 21 into the given function.
y = 20(21) + 0
y = 420 + 0
y = 420
Therefore, the predicted amount of sales when Temperature is 21 degrees Celsius is $420.
(c) What does the number 0 in the function mean in the contest of this situation?
In a linear interpretation which the function represents, the number 0 can be seen as the y intercepts of the function.

16x + 3 what is x
Answer:
x = 8
Step-by-step explanation:
17x-5 = 16x + 3
Step 1: Subtract 16x from both sides.
17x−5−16x=16x+3−16x
x−5=3
Step 2: Add 5 to both sides.
x−5+5=3+5
x=8
The solution to the equation is x = 8.
To solve the equation 17x - 5 = 16x + 3 and find the value of x, we can follow these steps:
Start by simplifying both sides of the equation by combining like terms. Add 5 to both sides to move the constant term to the right side of the equation:
17x - 5 + 5 = 16x + 3 + 5
17x = 16x + 8
Next, we want to isolate the x term on one side of the equation.
Subtract 16x from both sides:
17x - 16x = 16x - 16x + 8
x = 8
Therefore, the solution to the equation is x = 8.

The range of the exponential function f(x) is 1 / 32 ≤ f(x) ≤ 16.
How to find the range of an exponential function
Exponential functions are monotonous functions, that is, functions that are increasing or increasing but never both. Functions are defined by the following three features:
Domain - Set of input variables.Range - Set of output variables.Relation - Relations between domain and range.In this problem we find a function with an input variable (x) and an output variable (f(x)). Since exponential functions are monotonous functions we can determine the bounds of the range by the function evaluated at x = - 5 and x = 4. Thus:
f(- 5) = 2⁻⁵
f(- 5) = 1 / 2⁵
f(- 5) = 1 / 32
f(4) = 2⁴
f(4) = 16

among all rectangles that have a perimeter of 48, find the dimensions of the one whose area is largest. write your answers as fractions reduced to lowest terms.
among all rectangles that have a perimeter of 48 Then the dimensions of the one whose area is largest is 12 by 12
The formula for calculating the perimeter of a rectangle is expressed as:
P = 2(L + W)
L is the length of the rectangle
W is the width
Given that the perimeter is 156, hence;
2(L + W) = 48
2L + 2W = 48
L + W = 24
W = 24 - L
The area of the rectangle is expressed as:
A = LW
A = L(24-L)
A = 24L - L^2
To get the dimensions of the one whose area is largest, dA/dL = 0
dA/dL = 24 - 2L
0 = 24 - 2L
2L = 24
L = 24/2
L = 12
Recall that 2(L+W) = 48
2(12 + W) = 48
12 + W = 24
W = 24 - 12
W = 12
Hence the dimensions of the one whose area is largest is 12 by 12

Filling in the blanks, I assume you're talking about a random variable [tex]X[/tex] distributed uniformly over the integers [tex]a\le x\le b[/tex]. Let both [tex]a,b>0[/tex] so we can write the support of [tex]X[/tex] as the set
[tex]S = \{-a, -a+1, -a+2, \ldots, -1, 0, 1, \ldots, b-2, b-1, b\}[/tex]
Note that [tex]|S| = a+b+1[/tex], so the PMF of [tex]X[/tex] is
[tex]\mathrm{Pr}(X=x) = \begin{cases}\frac1{a+b+1} & \text{if } x\in S \\ 0 & \text{otherwise}\end{cases}[/tex]
Let [tex]Y=\max\{0,X\}[/tex]. Then
[tex]Y = \max\{0,X\} = \begin{cases}0 & \text{if } X\le0 \\ X & \text{if } X>0 \end{cases}[/tex]
which tells us
[tex]\displaystyle \mathrm{Pr}(Y=0) = \mathrm{Pr}(X\le0) = \sum_{x=-a}^0 \mathrm{Pr}(X=x) = \frac{a+1}{a+b+1}[/tex]
and
[tex]\displaystyle \mathrm{Pr}(Y\neq0) = \mathrm{Pr}(X>0) = \sum_{x=1}^b \mathrm{Pr}(X=x) = \frac b{a+b+1}[/tex]
Hence the PMF of [tex]Y[/tex] is
[tex]\mathrm{Pr}(Y=y) = \begin{cases}\frac{a+1}{a+b+1} & \text{if } y=0 \\\\ \frac b{a+b+1} & \text{otherwise}\end{cases}[/tex]
Let [tex]Z=\min\{0,X\}[/tex]. The same reasoning applies, but this time
[tex]Z = \min\{0,X\} = \begin{cases} 0 & \text{if } X \ge 0 \\ X & \text{if } X < 0 \end{cases}[/tex]
Now
[tex]\displaystyle \mathrm{Pr}(Z=0) = \mathrm{Pr}(X\ge0) = \sum_{x=0}^b \mathrm{Pr}(X=x) = \frac{b+1}{a+b+1}[/tex]
and
[tex]\displaystyle \mathrm{Pr}(Z\neq0) = \mathrm{Pr}(X<0) = \sum_{x=-a}^{-1} \mathrm{Pr}(X=x) = \frac a{a+b+1}[/tex]
so that

the population of rabbits on an island is growing exponential in the year 2008, the population of rabbits was 7100 and by the year 2013 the population had grown to 8900 . Predict the population of rabbits by the year 2023 to the nearest whole number
The population of rabbits by the year 2023 is 13985.
What will the population be?We have to use the following exponential function. This will be:
y = a b^t
In 2008 means, t=0
So we have 7100 = a b^0
a = 7100
y = 7100b^t
In 2013 means t = 2013-2008 =5
8900 = 7100 b⁵
b⁵ = 89/71
b = 1.046
So the equation will be
y = 7100 (1.046)^t
For 2023, t=2023-2008= 15
y = 7100(1.046)¹⁵
= 13985
