The function at x = -2 has a value of -1
How to evaluate the function?The graph represents the given parameter
From the question, we understand that:
The graph is a piecewise function
This means that there are breaks in the values represented on the graph
The x value is given as
x = -2
When this value is traced on the graph, we have
When x = -2, y = -1
When x = -2, y = 7
By considering the endpoint values of the domain, we have
When x = -2, y = -1 (inclusive)
When x = -2, y = 7 (not inclusive)
This means that
When x = -2, y = -1
Hence, the value of the function is -1

Investment X gives a greater amount of $50.40 over a period of two years
Investment X:
Principal amount invested = $6000
Time in years = 2 years
Rate of interest = 4.5%
Type of interest: Simple
Finding the interest using the formula for simple interest:
Simple interest = P*R*T/100
where P = principal invested
R = rate of interest
T = time in years
Substituting the values we get:
Simple interest = 6000*4.5*2/100
= $540
Investment Y:
Principal amount = $6000
Time in years = 2 years
Rate of interest = 4%
Finding the interest using the formula
Compound interest = P(1+r/100)^n - P
where P = principal amount invested
r = rate of interest
n = number of years
Substituting the values in the formula we get:
Compound interest = 6000(1+4/100)^2-6000
= (6000*1.0816)-6000
=$489.6
So, the difference in amount = 540-489.6 = $50.40

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

Answers
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.

Which statement describes the basis for the proof that vertical angles are congruent?
Answers
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.
