A $2976
B $3472
C $3542
D $3720
Answers
Rule of thumb for month rent: Rent ≤ 28% of monthly gross income
Then,
Month gross income = $62,112/12 = $5,176
Affordable rent = 0.28*5176 = $1,449.28
Rounding to nearest dollar;
Affordable rent = $1,449.
The correct answer is C.
Part 2
Monthly rent = $1240
Security deposit = 80% of rent = 0.8*1240 = $992
Amount to be paid = 1240*2 + 992 = $3472

A researcher finds a negative correlation between the total number of people driving for pleasure and the sales of electric cars.
Which variable is most likely the lurking variable that explains the correlation?
population
gas prices
amount of rainfall
water prices
Answers
The correct answer is:
gas prices
Explanation:
As the number of people driving for pleasure goes down, the sales of electric cars go up. This is likely due to gas prices. As gas prices go up, fewer people drive for pleasure and more people purchase electric cars. Both are ways to reduce the amount of money spent on gasoline.
The option 'gas prices' variable is most likely the lurking variable that explains the correlation.
Given that a researcher finds a negative correlation between the total number of people driving for pleasure and the sales of electric cars.
It is required to find which variable is most likely the lurking variable that explains the correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
We have a negative correlation between:
The total number of people driving for pleasure and the sales of electric cars.
We know that the negative correlation means one variable decreases and as the other increases and vice versa.
If the sales of electric cars increase the total number of people driving for pleasure goes down.
This can happen if the gas prices go up fewer people drive for pleasure and more people buy an electric car.
Thus, the option 'gas prices' is correct.

Next, we are going to use the trig function Sine in triangle BCD to find the height, [tex]h[/tex], of the plane:
[tex]sin(30)= \frac{h}{4.39} [/tex]
[tex]h=4.39sin30[/tex]

Final answer:
The probability of picking a second black marble, given that the first marble picked was black, is 1.
Explanation:
To find the probability of picking a second black marble, given that the first marble picked was black, we can use the formula for conditional probability: P(A|B) = P(A and B)/P(B).
In this case, A represents the event of picking a black marble on the second draw, and B represents the event of picking a black marble on the first draw.
We are given that P(B) = 514, and the probability of picking two black marbles without replacement is 1091. Therefore, P(A and B) = P(A|B) * P(B) = (1091/514) * (514/1091) = 1.
So, the probability of picking a second black marble, given that the first marble picked was black, is 1.

A man weighs 180 lb. He jogs a mile in 8 minutes. How many calories has he used up?
Answers
A man weighing 180 lb has burned approximately 100 calories by jogging one mile, based on the average estimate that jogging one mile burns almost 100 calories.
The question relates to the calculation of calories burned during exercise, specifically jogging. Based on the information provided that running or jogging one mile burns almost 100 calories, we can calculate the energy expenditure for a man weighing 180 lb who jogs a mile in 8 minutes.
Since the provided calories burned per mile is an average, the actual number might vary slightly based on individual metabolism and effort level, but it serves as a useful approximation.
To determine how many calories the man has used up, we can use the given information:
Running or jogging one mile burns almost 100 calories.The man jogs a mile, which means he has burned approximately 100 calories for that activity.Therefore, the man has burned approximately 100 calories during his 8-minute mile jog.

Answers
The answer provides the experimental probability of selecting green or purple marbles, predicts the occurrences of rolling 3 or 5 on a number cube, and estimates the total number of people who enjoyed the movie.
Experimental Probability Calculation: In the given scenario, there are 8 green marbles and 2 purple marbles, making a total of 10 marbles. The probability of selecting a green or purple marble is the sum of the individual probabilities, which is (8/10) + (2/10) = 0.8.
Expected Outcome of Rolling a Number Cube: Since a standard number cube has numbers 1 to 6, each number has an equal probability of 1/6. Predicting how many times 3 or 5 will be rolled out of 180 rolls can be calculated by (1/6 + 1/6) x 180 = 60 times each for 3 and 5.
Total Number of People Who Enjoyed the Movie: Based on the sample data, 4,200 out of 8,000 people enjoyed the movie. Extrapolating this to the total viewers, the predicted number of people who enjoyed the movie would be: (4,200/8,000) x 500,000 = 262,500 people.

Question:
Part A: Explain what the parameter 2,400 represents in the equation of the function.
Part B: What is the factor by which the printer depreciates each year?
Part C: Amy also considered purchasing a printer that costs $4,000 and depreciates by 25% each year. Which printer will have more value in 5 years? Justify your answer by showing/explaining your work.
i really need help :( im working hard to get all my school work done and this one thing is making my head hurt :(
Answers
The parameter 2,400 in the depreciation function represents the initial value of Amy's printer. The printer depreciates by a factor of 0.86 each year. After calculations, the first printer has more value ($1,004.40) after 5 years compared to the second printer ($949.24).
Part A: The parameter 2,400 represents the initial purchase price or the original value of the printer that Amy owns in her graphic design store.
Part B: The factor by which the printer depreciates each year is 0.86 (which is calculated as 1 - 0.14, meaning the value retains 86% of its worth each subsequent year).
Part C: To compare which printer will have more value in 5 years, we need to calculate the future value of both printers using their respective depreciation rates:
First printer: V = 2,400(1 - 0.14)^5Second printer: V = 4,000(1 - 0.25)^5After calculating:
Value of the first printer after 5 years: V \\approx 2,400(0.86)^5 \\approx 2,400(0.4185) \\approx $1,004.40Value of the second printer after 5 years: V \\approx 4,000(0.75)^5 \\approx 4,000(0.2373) \\approx $949.24Therefore, the first printer will have more value after 5 years.

True
EXPLANATION
According to the Rational Roots Theorem,the rational roots of a polynomial function F(x) can be written in the form

,
where p is a factor of the constant term of the polynomial, and q is a factor of the leading coefficient.
The polynomial must be written in standard form.
This means the polynomial must be written in descending powers of x.
The leading term is the first term of a polynomial written in standard form.
The constant term is the term independent of x.
