The line that has the slope with the greatest value is determined as the: A. Blue line.
How to Find the Slope of a Line?The slope of a line is the change in y over the change in x, which can also be calculated as:
Slope (m) = rise / run = y2 - y1 / x2 - x1.
Also, the steeper the slope, the greater the value of the slope that you will get, while the more gentle the slope, the smaller the value of the slope of the line we would get.
Out of the three lines shown in the graph, the steepest is the blue line, this means that it has the greatest slope value.

The wingspan (in feet) of the actual airplane is equal to 87.5 feet.
A property of equality which you would use to solve the equation -15 = x/3 + 18 is: D. Subtraction property of equality and multiplication of equality.
The solution of the equation 280 = -8(-14 + x) is: B. x = -21.
How to determine the wingspan (in feet) of the actual airplane?Based on the scale model, we can logically deduce that the airplane has a length of 12.2 inches and a wingspan of 12.5 inches. This ultimately implies that, we would convert from inches to feet as follows;
1 inch = 1/12 feet
12.2 inches = 12.2 × 1/12 = 12.2/12 feet.
Therefore, the scaled factor is given by;
Scale factor = (85.4 × 12/12.2)
For the actual length of the wingspan with a scaled length of 12.5 inches, we have:
12.5 inches = 12.5/12 feet
Actual length of wingspan = 12.5/12 × (85.4 × 12/12.2)
Actual length of wingspan = 87.5 feet.

Luc is playing a trivia game with multiple choice questions. He runs out of time and needs to guess on the last 2 22 questions. Each question has 4 4
Answers
The requried probability that Luc gets both questions correct is 1/16 or approximately 0.0625.
The probability of guessing a single question correctly is 1/4, since there are 4 answer choices and only 1 is correct. Since the questions are independent, the probability of guessing both questions correctly is the product of the probability of guessing each question correctly.
Therefore, the probability that Luc gets both questions correct is:
P(both correct) = P(first correct) * P(second correct)
P(both correct) = (1/4) * (1/4)
P(both correct) = 1/16
Thus, the probability that Luc gets both questions correct is 1/16 or approximately 0.0625.

The business checking account for a pottery store had a balance of $7349.44 before checks for $1349.67 and $344.12 were written. The store manager then deposited $956.60. Find the checkbook balance
Answers
The checkbook balance is $5703.25.
To find the checkbook balance, we need to start with the original balance and then subtract the amounts of the checks written and add the amount of the deposit.
Original balance: $7349.44
Checks written: $1349.67 + $344.12 = $1693.79
Deposit: $956.60
To find the checkbook balance, we can subtract the total amount of the checks written from the original balance and then add the deposit:
Checkbook balance = Original balance - Checks written + Deposit
Checkbook balance = $7349.44 - $1693.79 + $956.60
Checkbook balance = $5703.25

Answer:
To find the probability that a person surveyed is under 40 given that he or she gets the news by reading the paper, we need to use Bayes' theorem:
P(Under 40 | Read paper) = P(Read paper | Under 40) * P(Under 40) / P(Read paper)
where
P(Under 40 | Read paper) is the probability that a person is under 40 given that he or she gets the news by reading the paper
P(Read paper | Under 40) is the probability that a person under 40 reads the paper (36/80)
P(Under 40) is the overall probability of selecting a person under 40 (40/80)
P(Read paper) is the overall probability of selecting a person who reads the paper, calculated as the sum of those who are under 40 and read the paper and those who are 40 or older and read the paper (36+24)/(80)
Plugging in the values, we get:
P(Under 40 | Read paper) = (36/80) * (40/80) / ((36+24)/80)
P(Under 40 | Read paper) = 0.6
So the probability that a person surveyed is under 40, given that he or she gets the news by reading the paper, is 60%.

5(2x+2)-12x simplify
Answers
The simplified expression is 120x³ + 120x².
To simplify the expression 5x(2x+2)12x, we can use the distributive property of multiplication over addition and simplify the resulting terms.
First, we distribute 5x to the expression (2x+2), which gives us:
5x(2x+2) = 10x² + 10x
Next, we can multiply the result by 12x:
12x(10x² + 10x) = 120x³ + 120x²
Therefore, the simplified expression is 120x³ + 120x².
We can see that the original expression was a multiplication of three factors, and we used the distributive property to simplify it by expanding and multiplying the resulting terms. The final expression has a common factor of 120x², which we can factor out to get 120x²(x+1).

An engineer traveled 140 mi by car and then an additional 750 mi by plane. The rate of the plane was three times the rate of the car. The total trip took 6 h. Find the rate of the car.
Answers
The rate of car is 35 mph.
Given that engineer traveled 140 mi by car and then an additional 750 mi by plane. The rate of the plane was three times the rate of the car.
Let c be the rate of wind.
215 + c = rate of plane with wind
215 - c = rate of plane against wind
Therefore, the travel time =distance/rate
⇒ 750/(215+c) = 540/(215-c)
Cross multiplying we get,
540(215+c) = 750(215-c)
116100+540c = 161250-750c
