The correct statement regarding the proportional relationships is given as follows:
B. Karleigh ran a greater distance. The slope of the line described by the data in her table increased at a rate of 1/10, compared to 1/12 for Andrew.
How to obtain who run faster?
To obtain the person who runs faster, we need to look at their rates, as the time and the distance form a proportional relationship.
Andrew ran 1.5 miles in 18 minutes and 2 miles in 24 minutes, hence his rate is given as follows:
k = 1.5/18 = 2/24 = 1/12 = 12 minutes per mile.
Karleigh ran 3 miles in 30 miles and 4 miles in 40 minutes, hence her rate is given as follows:
k = 3/30 = 4/40 = 1/10 = 10 minutes per mile.
Due to the lower number of minutes per mile, Karleigh ran faster, and the correct option is given by option B.
Missing InformationAndrew ran 1.5 miles in 18 minutes and 2 miles in 24 minutes.
Karleigh ran 3 miles in 30 miles and 4 miles in 40 minutes.

What is a quadratic equation?The meaning of quadratic equation is any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.
Given is a quadratic equation,
For this case, the first thing we must do is rewrite the polynomial:
x² + 7x - 4 = 0
We use the resolver to solve the problem using quadratic formula;
x = (- b ± √(b² - 4 × a × c)) / (2 × a)
Where,
a = 1
b = 7
c = -4
Substituting the values:
x = (- 7 ± √((7)² - 4 × (1) × (- 4))) / (2 × (1))
x = (- 7 ± √(49 + 16)) / (2×(1))
x = (- 7 ± √(65)) / (2)

What is the median of 23?
The Median of 23 will be 23.
How to calculate the Median?
A data set's median value is the point where 50% of the data points have values that are lower or equal to it, and 50% of the data points have values that are higher or equal to it. In a list of odd numbers, one would select the middle number with an equal number of numbers on either side of it to determine the median value. The numbers should be arranged in order, typically from lowest to highest, before calculating the median.
The middle pair must be identified, added, then divided by two in order to calculate the median value in a list of even integers. Once more, group the figures from lowest to highest.
The median will be the average of the two middle numbers, in our questions 23 and 23, the mean of which is 23 because there are an even number of values.
So the final answer will be 23.

What is the slope ratio for 30 degree angle?
The slope ratio for a line that makes an angle of 30 with the positive direction of the x-axis is 1:√3
The slope of a line is nothing but the change of the line in the y-coordinate concerning the change in the x-axis. So the slope is simply nothing but a ratio of change in the y-axis to change in the x-axis which is also called slope ratio.
m = change in y / change in x
tan 30= 1/√3 = change in y / change in x
tan 30= 1: √3

Answer:
no solutions
Step-by-step explanation:
y = -x + 4
y=-x+1
-x+1 = -x+4 ==> since y=-x+1 and y=-x+4, -x+1=-x+4
-x+1-1 = -x+4-1 ==> isolate x on one side by subtracting 1 on both sides
-x = -x+3
-(-x) = -(-x+3)
x = x - 3 ==> this isn't equal since a number won't have the same value if
you take away 3 from it.
Hence, there are no solutions.
Answer:
There is no solution
Step-by-step explanation:
y = -x + 4
y=-x+1
If we solve
-x + 4 = -x +1
Add x to both sides and it will be 0
So, there is no solution!

What is (3x^3 −2x^2 +6x−1) subtracted from the sum
of (2x^3 −3x+2) and (5x^2 +4x−6)?
Answer:
the result of subtracting (3x^3 −2x^2 +6x−1) from the sum of (2x^3 −3x+2) and (5x^2 +4x−6) is −x^3 +3x^2 +7x−5.
Step-by-step explanation:
To find the result of subtracting (3x^3 −2x^2 +6x−1) from the sum of (2x^3 −3x+2) and (5x^2 +4x−6), we can first add the two given expressions to find the sum, and then subtract the third expression from that sum.
The sum of (2x^3 −3x+2) and (5x^2 +4x−6) is:
(2x^3 −3x+2) + (5x^2 +4x−6) = 2x^3 +5x^2 −3x+4x −6 = 2x^3 +5x^2 +x−6
Subtracting (3x^3 −2x^2 +6x−1) from this sum gives us:
(2x^3 +5x^2 +x−6) − (3x^3 −2x^2 +6x−1) = (2x^3 −3x^3) + (5x^2 −2x^2) + (x+6x) − (−1−6) = −x^3 +3x^2 +7x−5
Therefore, the result of subtracting (3x^3 −2x^2 +6x−1) from the sum of (2x^3 −3x+2) and (5x^2 +4x−6) is −x^3 +3x^2 +7x−5.

The system of the equation's solution is x = -6 and y = 4 which is determined by graphically.
The system of equations is given in the question as:
y = 1/6 x + 5
4x + 3y = -12
For the first equation, y = 1/6x + 5, we can plug in two values for x and solve for y to find two points on the line. Let's plug in x = 0 and x = 1 to find two points:
When x = 0, y = 1/6(0) + 5 = 5. So the point (0, 5) lies on the line.
When x = 1, y = 1/6(1) + 5 = 5 + 1/6 = 5 1/6. So the point (1, 5 1/6) lies on the line.
For the second equation, 4x + 3y = -12,
Let's plug in y = 0 and y = 1 to find two points:
When y = 0, 4x + 3(0) = -12.
4x = -12, so x = -3. So the point (-3, 0) lies on the line.
When y = 1, 4x + 3(1) = -12.
4x + 3 = -12, so x = -4. So the point (-4, 1) lies on the line.
To solve these equations graphically, we plotted the lines on the coordinate plane, found the point of intersection, and then found the coordinates of that point.
Thus, the solution to the system of equations is x = -6 and y = 4.

Answer:
C. BA ≅ DA
Step-by-step explanation:
⭐ What is the HL theorem?
The HL theorem is a triangle congruence statement used to say that 2 right triangles are congruent.For 2 right triangles to be considered by the HL theorem, they must have congruent hypotenuses and congruent corresponding legs✔️In this problem, it is already established that ΔABC and ΔADC are right triangles because they have a right angle.
✔️ΔABC and ΔADC have congruent hypotenuses because they both share hypotenuse AC, and by the reflexive property of congruence, AC ≅ AC
❌There is no indication that their corresponding legs are congruent, and that is what we need for the HL theorem.
The only answer option that mentions their corresponding legs being congruent is option C.
Why can t we use AAA to prove two triangles are congruent?
Knowing merely angle-angle-angle (AAA) does not work, because it can result in triangles that are similar but not congruent.
A set of triangles must have equal sides and angles in order for them to be congruent. The sides of the triangles may or may not be equal in the case of a triangle with all of the corresponding angles equal, or the AAA condition.
Only if the two triangles are similar would the congruence be true for two triangles with identical respective angles. Thus, we are unable to utilize AAA to establish the congruence of two triangles.

What is mean method formula?
The mean formula in statistics for a set is defined as the sum of the observations divided by the total number of observations.
One of the most significant and often employed metrics of central tendency is the mean. In mathematics, there are various different kinds of means. In statistics, the mean is the product of all the values in a set of data divided by the total number of values in the data for a particular set of observations.
To put it another way, calculating the mean of a data set only requires adding up all the values and dividing the result by the total number of values.
However, depending on whether grouped or ungrouped data is provided, the basic approach and formulae change. Ungrouped data is a collection of random observations, whereas grouped data is a collection of individual observations of a variable aggregated into separate groups.
