One motorcycle travels 80 mph and the second motorcycle travels 60 mph. if the faster motorcycle travels 1 hr longer than the slower motorcycle and it also travels twice the distance of the slower motorcycle, what distance does each motorcycle travel?
Answers
Each motorcycle travel a distance of 240 miles for the faster motorcycle and 120 miles for the slower motorcycle.
An algebraic expression is the combination of numbers and variables in expressing and solving a particular mathematical question. An equation is the equality of expressions.
Let x = time it took the faster motorcycle to travel
If the faster motorcycle travels 1 hr longer than the slower motorcycle, then the slower motorcycle travels x - 1 hours.
The product of the rate of speed and time is equal to the distance.
Hence, the distance traveled by the faster motorcycle is 80x, while the distance traveled by the slower motorcycle is 60(x - 1).
If the faster motorcycle travels twice the distance of the slower motorcycle, then the distance traveled by the slower motorcycle is 80x/2.
60(x - 1) = 80x/2
Simplify and solve for x.
60(x - 1) = 80x/2
60x - 60 = 40x
20x = 60
x = 3
distance traveled by the faster motorcycle = 80x = 80(3) = 240 miles
distance traveled by the slower motorcycle = 80x/2 = (80)(3)/2 = 120 miles

Answers
The main difference between opinion based and informational essay is that in opinion based you have to share your own opinion reading any topic or something but in case of informative essay to have to provide particular information about the subject.
What is essay?Generally speaking, an essay is a bit of writing in which the author presents their own arguments; nevertheless, this definition seems ambiguous and includes elements of letters, papers, articles, pamphlets, and short story collections. Essays are divided into two categories: formally and informally. Formal writings are distinguished by their "serious aim, dignity, logical arrangement, and length," whilst informal papers are distinguished by their "personal element."
To express your opinions on a subject and persuade the reader of your point of view, you must write an opinions essay. To accomplish it, you must first present the subject and express your viewpoint. Following that, you should provide three arguments in favor of your viewpoint. Finally, create a closing in which you summarize your case and restate your viewpoint in a new way.

A school had 1 200 students last year and only 1 080 students this year. What was the percent decrease in the number of students?
Answers
The percentage decrease in the number of students in the school was 10%.
What is the percentage?The percentage refers to the ratio or proportion of students that reduced the number of the school population for the present year in comparison to last year's.
We can compute the percentage by finding the decrease in population and taking the result as a numerator of the total number in the last year and multiplying the result by 100.
Percentages represent fractional values and are usually depicted by the percentage sign (%).
The total number of students in the school last year = 1,200
The total number of students in the school this year = 1,080
The decrease in the number of students = 120 (1,200 - 1,080)
The percentage decrease = 10% (120/1,200 x 100)
Thus, we can conclude that the school population decreased by 10%.

true or false? the sum of the numbers of dots that show up when we roll three dice simultaneously does not follow a discrete uniform distribution.
Answers
It is false, that the sum of the numbers of dots that show up when we roll three dice simultaneously does not follow a discrete uniform distribution.
What is Discrete uniform distribution?The Discrete uniform distribution is a symmetric probability distribution used in probability theory and statistics. It contains a finite number of values that are equally likely to be observed; each value has an equal chance of 1/n. "A known, finite number of outcomes equally likely to occur" is another approach to describe the discrete uniform distribution.
The perfect example of Discrete uniform distribution is throwing a die. Tossing a fair dice is an easy illustration of the discrete uniform distribution. The possible results are 1, 2, 3, 4, 5, and 6, and the likelihood of a certain result is 1/6 each time the die is thrown. Because not all sums have an equal chance, the distribution that results when two dice are thrown and their values are summed is no longer uniform.
From the above observation, we can say that the sum of the number of dots that show up when we roll three dice simultaneously will follow a discrete uniform distribution.

The length of the garden is: l ≥ 6225ft.
Area = L multiplied by W. Since you measure the area in square feet, your final number should reflect that.
What is a Rectangle?The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.
Let l serve as a symbol for the garden's length.
Let w be the symbol for the garden's width.
The perimeter is 540 feet.
The rectangle's circumference is equal to
2(l + w)2(l + w) = 540 l + w = 270. (1)
The rectangle's area is equal to its length times its width, which equals 12000. (2)
Make the variable w the subject of the following equation:
w = 270 - l. (3)
Substitute equation (3) into equation (2)
(270 - l)(l) ≤ 12000

Answers
A 99% confidence interval of what the actual average mileage is for a car before it is junked is; (153589, 174411)
How to find the confidence Interval?The formula for confidence interval is;
CI = x' ± z(s/√n)
where;
x' is sample mean
s is standard deviation
n is sample size
z is critical value at confidence level
We are given;
x' = 164000

s = 28000
CL = 99%
z-score at confidence level of 99% is 2.576
