Answer: The inequality that represents the condition based on the number of gallons of fuel will be:
[tex]3300P +5700S \geq94500[/tex]
The inequality that represents the condition based on the number of minutes will be:
[tex]75P +130S\geq2400[/tex]
Step-by-step explanation:
Let P denote the number of round trips to Prague and S the number of round trips to Stockholm.
Since the plane requires 3300 gallons of fuel and 75 minutes to make a round trip to Prague and 5700 gallons of fuel and 130 minutes to make a round trip to Stockholm.
Then the inequality that represents the condition based on the number of gallons of fuel will be:
[tex]3300P +5700S \geq94500[/tex]
The inequality that represents the condition based on the number of minutes will be:
[tex]75P +130S\geq2400[/tex]

Using the given xy-graph, find the equation of the given line E in slope-intercept form.
The equation of line E will be x = 8.
What is a linear equation?A relationship between two or more parameters that, when shown on a graph, produces a linear model. The degree of the variable will be one.
The linear equation is given as,
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
From the diagram, line E is perpendicular to the x-axis and parallel to the y-axis.
The slope of the line which is parallel to the y-axis will be ∞. Then the equation of line E will be
y = ∞x + c
y = (1/0)x + c
0y = x + c
x + c = 0
From the graph, the value of the variable c will be negative 8.
Then the equation of line E will be x = 8.

You have five identical pieces of equipment. There is a 1 in 10 chance that each piece will fail in a year. What is the likelihood that NONE of the pieces fail during a year?
The probability that none of the five identical pieces of equipment will fail during a year is approximately 59.049%, calculated using the statistical independence of each piece's probability of not failing, which is 0.9, raised to the power of 5.
The question is asking for the probability that none of the five pieces of equipment fails within a year when there is a 1 in 10 chance of failure for each piece of equipment. To calculate this, we use the principle of statistical independence. If the chance that one piece of equipment does not fail is 9 in 10 (or 0.9), then the probability that all five do not fail is 0.9 raised to the power of 5.
Mathematically, this is calculated as:
[tex](0.9)^5[/tex]= 0.9 * 0.9 * 0.9 * 0.9 * 0.9
Performing the multiplication, the probability that none of the five pieces fail during a year is approximately 0.59049.
In conclusion, there is a 59.049% chance that none of the identical pieces of equipment will fail during a year, assuming that the failures are statistically independent events.
five cards are drawn from a standard deck of cards. each card is replaced after being drawn. what is the probability of the following event: p(3 and 3 and 3 and 2 and 2)?
General Idea:
If A and B are independent, then the probability that events A and B both occur is:
[tex] p(A\; and\; B) = p(A) \times p(B). [/tex]
In other words, the probability of A and B both occurring is the product of the probability of A and the probability of B
Applying the concept:

Given a collection of paired sample data, the ____________ algebraically describes the relationship between the two variables, x and y.
Final answer:
The linear equation describes the algebraic relationship between two variables in a paired sample data set, with the slope and y-intercept being key components of this equation.
Explanation:
Given a collection of paired sample data, the linear equation algebraically describes the relationship between the two variables, x and y. The most fundamental representation of a linear association is through a linear equation, which graphically manifests as a straight line in a scatter plot. Two commonly used forms of linear equations are y = mx + b and y = a + bx. The latter is frequently used in statistical contexts to differentiate from the algebraic context.
In these equations, m or b (when used as a coefficient) is known as the slope, indicating the rate of change or how much y changes as x changes. The y-intercept represented by a is the point at which the line crosses the y-axis, typically where x equals zero. A linear relationship between two variables is confirmed when a scatter plot of the pair shows points that approximate a straight line.

Which graph represents the function?
The resulting graph of the rational function is the Graph at the top right graph 2.
To depict the rational function f(x) = 2/(x - 1) + 3, we must consider its characteristics. The function has a vertical asymptote at x = 1 because the function is undefined at that point, and it has a horizontal asymptote at y = 3 due to the behavior of the function as x approaches infinity. The graph will approach these asymptotes but never cross them.
For values of x greater than 1, the function will decrease towards the horizontal asymptote because the (x - 1) in the denominator increases, which causes the value of f(x) to decrease.
However, because of the '+3' term in the function, the curve will approach y = 3 as x goes to infinity.
To graph this function, plot several points where x is not equal to 1, then draw the curve that passes through these points while approaching the respective asymptotes.
The portions of the graph should fall above the horizontal line y = 3 for x < 1 and approach y = 3 from below for x > 1.
Therefore, the resulting graph of the rational function is the Graph at the top right graph 2.
The probable question may be:
Which graph represent the rational function f(x)=2/x-1+3
A tire at the top of a hill starts rolling down the hill. If the diameter of the tire is 36 inches, how many inches has the tire rolled if it has rotated exactly 10 times down the hill?
A) 180
B) 360
C) 36π
D) 360π
Answer:
Therefore ,(D) 360π inches.
Step-by-step explanation:
Given: A tire at the top of a hill starts rolling down the hill. If the diameter of the tire is 36 inches.
To find: How many inches has the tire rolled if it has rotated exactly 10 times down the hill.
Solution : We have given that diameter of tire = 36 inches.
Radius = [tex]\frac{Diameter}{2}[/tex]
Radius = [tex]\frac{36}{2}[/tex]
Radius = 18 inches.
Circumference of tire = 2 * π radius
Circumference of tire = 2 * π 18
= 36π
We need to rolled the tire 10 times down the hill
then, 10 * 36π = 360π inches.
Therefore ,(D) 360π inches.

Will bought 3 college textbooks. One cost $32, one cost $46, and one cost $39. What is the average price of his books? What statement correctly calculates the average
The average price of the textbooks Will bought is $39, calculated by adding the individual prices and dividing by the number of books.
To calculate the average price of the textbooks Will bought, we simply sum up the costs of the three textbooks and divide by the number of textbooks. Let's do the math:
Add the cost of the textbooks: $32 + $46 + $39 = $117.Divide the total cost by the number of books: $117 / 3 = $39.The average price of the textbooks is $39.

140% of a number is 364. Find the number
The number whose 140% is 364 is 260.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number = M
140% of M = 364.
140/100 x M = 364
Solve for M.
M = 364 x 100 / 140
M = 260
Thus,
140% of 260 is 509.6.
