As an airline pilot, you strive forarrivals that are as close as possible toon-time. When measuring on-timearrivals based on minutes late, do youwant a higher or lower standarddeviation?LowerHigher
The standard deviation measures how far the data are from the dataset mean. The lower the standard deviation is, the closest the data are to the mean.
In this case, the pilot strives for a mean equal to 0 (zero minutes late). Also, since the pilot needs the arrivals to be as close as possible to this mean of zero minutes late (on-time), they want the data of "minutes late" to be all close to this mean. And this is achieved with a lower standard deviation.
Therefore, they want a lower standard deviation.

The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 5 to 4. If there were 2348 no votes, what was the total
number of votes?
A city's residents voted on whether to raise property taxes. The yes votes outnumbered the no votes 5 to 4. The total number of votes = 1043 if there were 2348 no votes.
What is Ratio and proportion?A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other.
For example, if there is one boy and three girls, the ratio could be written as 1: 3. (for every one boy there are 3 girls). In the ratio, the product of means equals the product of extremes.
If the cross products of two ratios are equal, they are said to be equal. The Proportion Formula is as follows: a: b:: c: d a b = c d
Therefore,
The total number of votes = 1043
yes votes / no votes = 5/4
Means there were a total of 9 votes;
So we could say:
No votes/Total votes = 4/9
So using total of 2348 votes, we can set up a proportion:
No votes/Total votes = 4/9 = x/2348
Cross multiplying ,
9392 = 9x
∴ x = 9392/9
= 1043

The graph shows the distance of a car traveling along a straight road for 8 hours. A positive velocity is motion to the right, and a negative velocity is motion to the left.
11. Determine the rates of change in distance with respect to time.
12. Between what two times is the car not moving
13. Between what two times is the car traveling to the right?
13. Between what two times is the car traveling to the left?
13. Between what two times is the car traveling the fastest?
What does the x-intercept (8, 0) represent in this situation
The graph of the distance traveled by the car to the time taken during the 8 hours along the straight road gives;
11. The rates of change between the following times, t, are;
t = 0 and t = 2 the rate of change is 30 mpht = 2 and t = 3 the rate of change is 60 mpht = 3 and t = 4 the rate of change is 0 mpht = 4 and t = 8 the rate of change is -30 mph12. The car is not moving between times 3 and 4 hours
13. The car is traveling to the right between times 0 and 3 hours
14. The car is traveling to the left between times 4 and 8 hours
15. The car is traveling fastest between times 2 and 3 hours
What is a distance–time graph?A distance–time graph is one that shows the variation of the distance traveled with respect to time, such that a positive distance traveled indicates a forward distance and a negative distance traveled indicates reversed motion.
The points on the graph in the possible question obtained online are;
(0, 0), (2, 60), (3, 120), (4, 120), (8, 0)
From the above points, the attached graph is constructed using Sheets
11. The rates of change in distance with respect to time are;
[tex] \displaystyle { \frac{ (\triangle d)_{1} }{ \triangle t} = \frac{60 - 0}{2 - 0} = 30}[/tex]; Velocity = 30 mph[tex] \displaystyle { \frac{ (\triangle d)_{2} }{\triangle t} = \frac{120 - 60}{3 - 2} = 60}[/tex]; Velocity = 60 mph[tex] \displaystyle { \frac{ (\triangle d)_{3} }{\triangle t} = \frac{120 - 1200}{4 - 3} = 0}[/tex]; Velocity = 0 mph[tex] \displaystyle { \frac{ (\triangle d)_{4} }{\triangle t} = \frac{0 - 120}{8 - 4} = - 30}[/tex]; Velocity= -30 mph12) When the car is not moving, we have that the rate of change of distance with time is zero, that is the car's distance does not change with time.
The two times between which the car is not moving is between the 3 hour and 4 hour points on the graph
13. The velocity of the car is given by the rate of change of the distance with time of the car
The positive rate of change on the graph is given between the times 0 and 3 hours after the car starts motion.
The car is traveling to the right between times, t = 0 and t = 3
14. The car has negative rate of change and therefore, negative velocity, and therefore also the car is moving to the left between times, t = 4 hours, and t = 8 hours
15. The car is traveling fastest when the rate of change of the car's distance traveled with time is highest, which is given by the times between t = 2 hours and t = 3 hours in which the car is traveling at 60 miles per hour

Which statement describes the basis for the proof that vertical angles are congruent?
The basis for the proof vertical angles are congruent is " two angles that are each supplementary to a third angle are congruent".
Vertical angles are a pair of non-adjacent angles formed by the intersection of two straight lines.
In the provided figure.
∠1 + ∠2 = 180 degrees ( linear pair of angles)...(i)
∠ 1 + ∠4 = 180 degrees ( linear pair of angles)...(ii)
According to transitive property, if a = b and b = c then a = c
Therefore,
∠1 + ∠2 = ∠1 + ∠4...(iii)
⇒∠2 = ∠4
Similarly, we can prove that
∠1 = ∠3
Therefore, we conclude that vertically opposite angles are always equal.
Hence, the basis for the proof vertical angles are congruent is " two angles that are each supplementary to a third angle are congruent".
Thus, statement c is correct.

If a₁ = 2 and aₙ = aₙ₋₁ - 4, then find the value of a4.
Answer
a₄ = -10
Explanation
If a₁ = 2 and aₙ = aₙ₋₁ - 4, then find the value of a₄.
We already know that
a₁ = 2
a₂ = a₁ - 4
a₃ = a₂ - 4
a₄ = a₃ - 4
Doing the substitutions
a₂ = a₁ - 4
a₂ = 2 - 4 = -2
a₃ = a₂ - 4
a₃ = -2 - 4 = -6
a₄ = a₃ - 4
a₄ = -6 - 4 = -10

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
Let x be the number of weeks on which Megan and Connor have saved the same amount.
Total amount(Megan) = 50 + 5.50x
Total amount(Connor) = 18.50 + 7.75x
Equate both equations:
50 + 5.50x = 18.50 + 7.75x
2.25x = 31.5
