A local store buys used video games. For each game bought, they will pay $18 less than the original price paid for the game. Which expressions represent the total amount Jordan will receive if he sells “n” games that originally cost “d” dollars each? Check all that apply.
Answer:
B. [tex]n(d-18)[/tex]
D. [tex]dn-18n[/tex]
Step-by-step explanation:
Let d represent the original price paid for the game.
We have been given that a local buys used video games. For each game bought, they will pay $18 less than the original price paid for the game.
The price of used video game would be original price minus 18. We can represent this information in an expression as:
[tex]d-18[/tex]
We have been given that Jordan sold n games, so the cost of n used games would be [tex]n(d-18)[/tex].
Using distributive property we will get,
[tex]n(d-18)=dn-18n[/tex]
Therefore, option B and D are correct choices.

128,96,72,54,...find the common ratio
To find the common ratio of the given sequence, divide each term by the previous term. The common ratio is 0.75.
Explanation:The given sequence is: 128, 96, 72, 54, ...
To find the common ratio, we need to determine the ratio between consecutive terms. We can do this by dividing each term by the previous term.
Ratio between the 2nd and 1st terms: 96/128 = 0.75
Ratio between the 3rd and 2nd terms: 72/96 = 0.75
Ratio between the 4th and 3rd terms: 54/72 = 0.75
Since the ratio is the same for all consecutive terms, we can conclude that the common ratio of this geometric sequence is 0.75.
The correct common ratio for the given sequence is [tex]\(\frac{3}{4}\) or 0.75.[/tex]
To find the common ratio of the sequence, we divide each term by the previous term and look for a consistent value:
1. For the second term, \(96\), divided by the first term, [tex]\(128\)[/tex], we get:
[tex]\[ \frac{96}{128} = \frac{3}{4} = 0.75 \][/tex]
2. For the third term, [tex]\(72\),[/tex] divided by the second term, [tex]\(96\),[/tex] we get:
[tex]\[ \frac{72}{96} = \frac{3}{4} = 0.75 \][/tex]
3. For the fourth term, [tex]\(54\),[/tex] divided by the third term, [tex]\(72\)[/tex], we get:
[tex]\[ \frac{54}{72} = \frac{3}{4} = 0.75 \][/tex]

Refer to the figure below to complete the following item. Given: Quadrilateral ROSE is trapezoid with median If MN = 24 and ES = 10, then RO = 27 30 38
Answer:
The length of RO is 38.
Step-by-step explanation:
Given information: ROSE is trapezoid with median If MN = 24 and ES = 10.
Sufficient information is not given. This question can be solved if it is given that [tex]RO\parallel ES[/tex].
According to the properties of trapezoid the length of the median is the average of length of parallel sides.
Let [tex]RO\parallel ES[/tex] and length of RO be x.
Since MN is median, therefore
[tex]MN=\frac{RO+ES}{2}[/tex]
[tex]24=\frac{x+10}{2}[/tex]
[tex]48=x+10[/tex]
[tex]x=38[/tex]

32.6 degrees
43.9 degrees
48.7 degrees
54.2 degrees
Answer: 48.7 degrees
Step-by-step explanation:
Let [tex]\theta[/tex] is the angle between the his sight line form with the side of the hotel,
Since, the building is of 5-story and a men having height 6 feet is in the fifth-story.
Thus, the total length from the eyes of the man and foot of the building = 6 + 12 × 5 = 6 + 60 = 66 feet
Also, the distance of the statue from the foot of the building = 75 feet.
Then by the below diagram,
[tex]tan\theta = \frac{75}{60+6}[/tex]
[tex]tan\theta = \frac{75}{66}[/tex]
[tex]\theta=48.6522227803\approx 48.7\text{ degree}[/tex]

The first team of workers received 50 kg of cement less than the second team. for every hour of work the first team was using 150 kg of cement, while the second team was using 200 kg. in three hours the first team had 1.5 times as much remaining cement as the second team. how much cement was delivered to each team of workers
To find out how much cement was delivered to each team, we can set up an equation based on the information provided and solve for the unknowns.
Explanation:Let's denote the amount of cement delivered to the second team as x kg. According to the question, the first team received 50 kg less, so they received x - 50 kg of cement.
The first team used 150 kg of cement every hour for 3 hours, so they used a total of 150 * 3 = 450 kg of cement. Therefore, they had 1.5 times as much remaining cement as the second team, which means they had 1.5 * (x - 50) kg of cement remaining.
Since we know that the remaining cement of the first team is equal to 450 kg, we can set up the following equation: 1.5 * (x - 50) = 450. Solving this equation will give us the amount of cement delivered to each team.

The first team received 750 kg of cement, and the second team received 800 kg of cement.
Let's denote the amount of cement delivered to the first team as [tex]\( x \)[/tex]kg and to the second team as[tex]\( y \)[/tex] kg. According to the problem, we have the following information:
1. The first team received 50 kg of cement less than the second team: [tex]\( x = y - 50 \)[/tex].
2. The first team uses 150 kg of cement per hour, and the second team uses 200 kg per hour.
3. After three hours of work, the first team has 1.5 times as much remaining cement as the second team.
Let's calculate the amount of cement used by each team after three hours:
- The first team uses [tex]\( 150 \times 3 = 450 \)[/tex] kg of cement.
- The second team uses [tex]\( 200 \times 3 = 600 \)[/tex] kg of cement.
Now, let's denote the remaining cement for the first team as [tex]\( R_1 \)[/tex] and for the second team as [tex]\( R_2 \)[/tex]. We can set up the following equations:
For the first team: [tex]\( R_1 = x - 450 \)[/tex].
For the second team: [tex]\( R_2 = y - 600 \)[/tex].
According to the problem, the remaining cement for the first team is 1.5 times that of the second team: [tex]\( R_1 = 1.5 \times R_2 \).[/tex]
Substituting the expressions for[tex]\( R_1 \)[/tex] and [tex]\( R_2 \)[/tex] into the equation, we get:
[tex]\( x - 450 = 1.5 \times (y - 600) \).[/tex]
Now, we can substitute[tex]\( x = y - 50 \)[/tex] into the equation:
[tex]\( (y - 50) - 450 = 1.5 \times (y - 600) \),[/tex]
[tex]\( y - 500 = 1.5y - 900 \),[/tex]
[tex]\( 0.5y = 400 \),[/tex]
[tex]\( y = 800 \).[/tex]
Now that we have [tex]\( y \)[/tex], we can find [tex]\( x \)[/tex]:
[tex]\( x = y - 50 \),[/tex]
[tex]\( x = 800 - 50 \)[/tex],
[tex]\( x = 750 \).[/tex]
How to find common difference of arithmetic sequence given first and last term?
To find the common difference, subtract the first term from the last term and divide by the number of terms minus 1.
Explanation:To find the common difference of an arithmetic sequence given the first and last term, you can use the formula: common difference = (last term - first term) / (number of terms - 1). First, subtract the first term from the last term. Then, subtract 1 from the number of terms. Finally, divide the result of the subtraction by the number of terms minus 1 to find the common difference.
Sam used 2 gallons of gas to drive 50 miles and 4 gallons of gas to drive 100 miles. Is this a proportional relationship? Explain your reasoning.
Sam's gas usage is a proportional relationship because he gets a constant 25 miles per gallon in both given scenarios.
Yes, this is a proportional relationship. To determine proportionality, we can calculate the gas mileage for each scenario. Gas mileage is calculated by dividing the number of miles driven by the number of gallons used. For the first scenario, the gas mileage is 50 miles / 2 gallons = 25 miles per gallon. In the second scenario, the gas mileage is 100 miles / 4 gallons = 25 miles per gallon. Since the gas mileage is the same in both cases, it indicates a proportional relationship.

Question 1: if you were to calculate a confidence interval using a confidence level of 0.9 and then calculated a second confidence interval using the same data but changed the confidence level to 0.95, would the interval be more narrow or wider?
The 95 percent confidence interval is wider than the 90 percent confidence interval because the 95 percent level of confidence includes more of the distribution. This means there is a greater level of certainty that the true value of the population mean is contained within the interval.
Explanation:The 90 percent confidence interval is (67.18, 68.82). The 95 percent confidence interval is (67.02, 68.98). The 95 percent confidence interval is wider. If you look at the graphs, because the area 0.95 is larger than the area 0.90, it makes sense that the 95 percent confidence interval is wider. For more certainty that the confidence interval actually does contain the true value of the population mean for all statistics exam scores, the confidence interval necessarily needs to be wider.

Explanation:To find the range of the function f(x) = 5x^2 + 4 for the given domain {-4, -2, 0, 1.5, 4}, we need to evaluate the function for each value in the domain and find the minimum and maximum outputs.
Substitute -4 into the function: f(-4) = 5(-4)^2 + 4 = 84Substitute -2 into the function: f(-2) = 5(-2)^2 + 4 = 24Substitute 0 into the function: f(0) = 5(0)^2 + 4 = 4Substitute 1.5 into the function: f(1.5) = 5(1.5)^2 + 4 = 16.75Substitute 4 into the function: f(4) = 5(4)^2 + 4 = 84The range of the function is the set of all possible outputs. In this case, the minimum output is 4 and the maximum output is 84. Therefore, the range of the function is {4, 84}.
According to the Rational Root Theorem, which statement about f(x) = 12x3 – 5x2 + 6x + 9 is true? Any rational root of f(x) is a multiple of 12 divided by a multiple of 9. Any rational root of f(x) is a multiple of 9 divided by a multiple of 12. Any rational root of f(x) is a factor of 12 divided by a factor of 9. Any rational root of f(x) is a factor of 9 divided by a factor of 12.
Answer:
Any rational root of f(x) is a factor of 9 divided by a factor of 12.
Step-by-step explanation:
Given:
f(x) = 12x³– 5x² + 6x + 9
Required; Rational root of f(x)
The rational root theorem states that: each rational solution
x = p⁄q, written in lowest terms so that p and q are relatively prime
Where
p = factors of the constant
q = factors of the lead coefficient.
Given that
f(x) = 12x³– 5x² + 6x + 9
The constant is 9
And the lead coefficient is 12
The factor of these two are
9; ±1 , ±3, ±9
12: ±1, ±2, ±3, ±4, ±6, ±12
Then the rational root of f(x) is
factor of 9 divided by a factor of 12.
Possible Rational Roots
= (±1 , ±3, ±9) / (±1, ±2, ±3, ±4, ±6, ±12)
The correct statement according to the rational root theorem is
The rational root of f(x) is
factor of 9 divided by a factor of 12
