Distance ran by Jake in a day is 17.33 miles.
It is given in the question that Jake ran 121.3 miles in a week. Also, Jake ran an equal number of miles each day.
We have to find the distance ran by him in a day.
Let the distance ran by him in a day be x miles.
We know that there are 7 days in a week.
Hence, according to the data given in the question, we can write,
Number of days in a week * distance ran in a day = total distance
Hence,
7*x = 121.3 miles
Solving the linear equation, we get,
x = 121.3/7 miles
x = 17.3285 ≈ 17.33 miles

A scale that allows us to rank individuals or objects, but not say anything about the meaning of the differences between the ranks, is an ordinal scale.
What is an ordinal scale?An ordinal scale is one that allows us to rank individuals or objects without saying anything about the significance of the differences between the ranks. The ordinal scale is the second level of measurement that reports data ranking and ordering without determining the degree of variation between them. Cases in the same class are regarded as equivalent. Movie ratings, political affiliation, military rank, and other variables that use ordinal scales are examples."Movie ratings" is an example of an ordinal scale.

Answer:

Step-by-step explanation:
As x aproaches a, (x-a) will aproach 0, so the numerator will aproach 0, and because 0 divided by anything=0, the whole function will become 0. So, the answer is 0.
James has a square garden with sides of length 8feet. he plans to enlarge it to a rectangle by increasing the length by 4 feet and the width by 1 feet. how many square feet in area will be added to the garden?
The area in square feet that will be added to the garden is 44 square feet.
Length of square garden = 8 feet
Area of Square garden = [tex](side)^{2}[/tex] = [tex](8)^{2}[/tex] = 64 square feet
On enlarging the square to a rectangle, length rectangular garden is (8+4)feet i.e.,12feet and width of rectangular garden is (8+1)feet i.e.,9feet.
Area of rectangular garden = (length × width)
= (12 × 9) square feet
= 108 square feet
The area in square feet that will be added to the garden = (Area of rectangular garden - Area of Square garden)
= (108 square feet - 64 square feet)
= 44 square feet
The area in square feet that will be added to the garden is 44 square feet.

Answer:
350p2+19500p-199000
(The first term is actually -350p² but I guess you have to write it as -350p2)
Step-by-step explanation:
Looks like that first term in the revenue equation is -350p²
We have
E = -1500p + 199000
R = -350p² + 18000p
Profit = Revenue - Expenses = R - P
Profit = -350p² + 18000p - (-1500p + 199000)
= 350p² + 18000p + 1500p - 199000
= 350p² + 19500p - 199000

Explain what is meant by confounding. what is a lurking variable? what is a confounding variable?
Answer:
A Confounding is the variable that is considered in a research study, and could overall influence the relations between the variables in the study. For example, students wanting to join AP English next semester were told to write a six page essay. When the students turned in their papers and teachers say the difference and grades they believed that the variable was the time that the students handed in the paper. They thought that if the student handed in their paper later than another student that they would receive a lower score, but this was not the case. When asking the students how they prepared for the paper, students replied with different answers. Those who outlined and used other literature for reference scored much higher than those who only used prior knowledge to write their essays. In this study, the lurking variable would be the presence of an outline.

What is a model?A mathematical model is a system description that employs math ideas and language. Mathematical modeling is the process of creating a mathematical model. Mathematical models are used in the natural sciences (physics, biology, earth science, chemistry), engineering disciplines (computer science, electrical engineering), and non-physical structures such as the social sciences (such as economics, psychology, sociology, political science). A large part of the field of operations research is the use of statistical equations to solve problems in business or military operations. Music, linguistics, and philosophy all use mathematical models (for example, intensively in analytic philosophy). A model is, for example, the method for the area of a circle, πr2.Therefore, πr2 is an example of (D) a model.

If the boy is riding a bicycle and gets stuck or got accident by a car, 440ml of IV fluid will be administered.
What should be done to provide first assistance in the event of an accident?To avoid further injury, place the victim on the ground very gently and slowly without handling vigorously. In one direction, tilt the sufferer. Dress loosely around the waist, chest, and neck. So that the tongue can fall forward and allow blood and vomit to drain out, tilt your head back and slightly downward. When you come across an accident victim, the first thing you need to determine is whether the victim's body has sustained any physical wounds. Depending on how severe the collision was, you might not be able to see any inside injuries, but you will see a few exterior ones.
In a car accident, spine injuries and head trauma are common. Therefore, be aware that rough handling of the sufferer will result in additional injuries while opting to assist the victim in moving to a safer location on the road. Therefore, request any onlookers to carefully assist in moving the sufferer to a location near the road where it will be safer.

Here,
Function is given as, f(x)=4x+1
And, translation 2 units left.
We have to find the function after translation.
Now,
Function is given as, f(x)=4x+1

L is the midpoint of JM. K is the midpoint
of JL. JL = 1. What is the length of KM?
Answer:
KM = 1.5
Step-by-step explanation:
The first piece of info we get is that L is the midpoint of JM. This means that L = JM/2. The second piece of information provided is that K is the midpoint of JL, which means K = JL/2. We know that JL = 1, so we can plug it into the equation to help us figure out the problem. You can also illustrate to solve this problem, as I do here.
Since JL = 1...
K = 1/2, K = 0.5
________________________________________________
J K(0.5) L M
___________ __________
0.5 0.5
Now with this information, we know that 0.5 represents the distance of 1/4 of JM. We know that KM is 3/4 of the number line, and we know that 1/4 of the line is 0.5. We multiply 0.5 * 3 to get our final answer.

The price of crude oil in 3.24 ¢ /cup.
What is conversion factor?A conversion factor is a number that is used to multiply or divide one set of units into another.
When converting to an equal value, the suitable conversion factor must be used. To convert inches to feet, for example, the suitable converting value is 12 inches equal 1 foot.A conversion factor is a ratio (and any fraction) that depicts the connection between two distinct units.Some conversion factors are-
One gallon = 4 quarts;
4 cups = 1 quart
( ¢ =cents)
Now, as per the given question;
The crude oil was sold at $21.75 per barrel.
The volume of the barrel is 42 gallons.
Let 'P' be the total price of crude oil in ¢ /cup.
To determine the price in cents per cup, we must use the conversion factors:
Price P = ($21.75/1 barrel)×(100 ¢/$ 1.00)×(1 barrel/42 gallons)×1 gallon/ 4 quarts)×(1 quartz/ 4 cups).
Simplify the above equation;
Price per cup P = 3.24 ¢ /cup.

The value of x is 3 days.
Here,
Jenna alone takes x days to finish a project.
Kelly alone takes 3 days more than Jenna alone to finish the project.
They together take 2 days to finish the project.
We have to find the value of x.
What is Mathematical expression?
Mathematical expression is a way where calculations and analytical processes should be observed.
Now,
Jenna alone takes x days to finish a project.
Hence, Jenna complete work in 1 day = 1/x work
Kelly alone takes 3 days more than Jenna alone to finish the project.
That is, x + 3 days.
Hence, Kelly complete work in 1 day = [tex]\frac{1}{x+3}[/tex] work
They together take 2 days to finish the project.
Hence, They together complete a work in 1 day = 1/2 work.
To find the value of x we use the formula of work word problem as;
[tex]\frac{1}{x} + \frac{1}{x+3} = \frac{1}{2} \\\\\frac{(x+3)+x}{x(x+3)} = \frac{1}{2}\\\\2(2x+3) = x (x+3)\\\\4x + 6 = x^{2} + 3x\\\\x^{2} -x-6=0\\\\x^{2} -3x+2x-6=0\\\\x (x-3) +2(x-3)=0\\\\(x+2) (x-3) = 0\\\\x = -2, x = 3[/tex]
Since, The value of x = -2 is not possible (because days are not shown in negative sign).
