The distance between points R and S is \(\sqrt{ (185)\). The correct answer is D. She made no errors.
Heather's work to find the distance between two points, R(-3,-4) and S(5,7), is shown:
RS = √(-4) (-3))² + (7 − 5)²
= √(-1)² + (2)²= √1 + 4
= √5
The error is with the order of subtraction in the formula for the distance between two points.
Heather did not make any errors in calculating the distance between two points. Therefore, the correct answer to the question above is (OD) She made no errors.
The formula for the distance between two points, A (x1, y1) and B (x2, y2), in the coordinate plane is given as;
dAB = \(\sqrt{ ((x^2 - x1)^2 + (y2 - y1)^2)\)
Comparing the given question with the formula above, we have;
A = R (-3, -4) and B = S (5, 7)The distance, AB = RS.
Therefore, we have;
RS = \(\sqrt{ ((5 - (-3))^2 + (7 - (-4))^2)\)
On solving the above equation;RS = \(\sqrt{ ((5 + 3)^2 + (7 + 4)^2)\)RS
= \(\sqrt{ (8^2 + 11^2)RS\)
= \(\sqrt{ (64 + 121)RS\)
= \(\sqrt{ (185)\)
Therefore, the distance between points R and S is \(\sqrt{ (185)\).
From the calculation, it is clear that Heather did not make any errors while calculating the distance between two points. The answer obtained by Heather is correct.

Your friend Kaipo is having some trouble plotting points on the coordinate plane. He thinks that he should plot the ordered pair (5,-8) by starting at the origin and counting 5 units up and 8 units to
the left. Help Kaipo understand the error in his thinking.
Answers
By using coordinate system of graph plotting, it can be obtained that Kaipo actually thought about plotting (-8, 5).
What is a coordinate system?
To locate the position of a point on the graph, coordinate system is used.
A set of two perpendicular axes on a graph divides the graph into four quadrants. Intersection of two axes is the origin. The left part of horizontal axis and top part of vertical axis from the origin is positive and the other parts are negative. A coordinate of a point is in the form of ordered pair. The first value is the value on the horizontal axis and the second value is the value on the vertical axis.
The first value of the coordinate is the value on the horizontal axis and the second value of the coordinate is the value on the vertical axis.
To plot (5, -8), it is required to move 5 units to the right from the origin and then move down 8 units.
Kaipo just did the opposite. He actually thought about plotting (-8, 5).

A straight highway is 100 miles long, and each mile is marked by a milepost numbered from 0 to 100. A rest area is going to be built along the highway exactly 7 miles away from milepost 58. If m is the milepost number of the rest area, which of the following equations represents the possible locations for the rest area?
Answers
Answer:
Step-by-step explanation:
The milepost number of the rest area is 7 miles away from milepost 58, so it can be represented by the equation:
m = 58 + 7
This equation states that the milepost number of the rest area is equal to 58 plus 7, or 65. Therefore, the rest area can be located at milepost 65.
In a given year, 1,791,408 males and 1,785,070 females were born in a certain country. If a child is selected randomly from this group, what is the probability that it is female?The probability is?
Answers
The formula for a probability is given by the next from:
\(P=\frac{\#\text{ number of favorable outcomes}}{Total\text{\# of posible outcomes}}\)We need to find the probability that by randomly selecting a child, the result will be a female.
The sample is:
1,791,408 males
1,785,070 females
Hence, there are 1,791,408 +1,785,070 = 3,576,478 total children.
Replacing on the formula:
\(P=\frac{1,785,070}{3,576,478}=0.499113\)Therefore, the probability is given by 0.499113...
Rounded to the nearest tenth:
P=0.5

What is the discriminant of a quadratic equation?A quadratic equation is defined as follows:

The numeric value of the coefficient and the number of solutions of the quadratic equation is defined as follows:
Δ > 0: two real solutions.Δ = 0: one real solution.Δ < 0: two complex solutions.For this problem, the coefficients are given as follows:
a = 1, b = -5k, c = 1.
The quadratic function, with c positive, will be greater than or equals to zero if it has at most one real solution, hence the condition is:
Δ ≤ 0.
Hence:
(-5k)² - 4(1)(1) ≤ 0
25k² - 4 ≤ 0.
25k² ≤ 4
k² ≤ 4/25
|k| ≤ 2/5 -> applying the square root.

Missy is wrapping a gift for her sister's birthday in a box with the dimensions shown.
17.5 in.
4 in.
10 in.
What is the minimum amount of wrapping paper she will need to completely cover the box?
Answers
Missy will need a minimum of 570 square inches of wrapping paper to completely cover the box.
To calculate the minimum amount of wrapping paper needed to cover the box, we need to find the surface area of the box.
A rectangular box has six sides: a top, a bottom, two sides, and two ends.
The top and bottom sides have the same dimensions, which are 17.5 inches by 10 inches. So each of these sides has an area of 17.5 in × 10 in = 175 square inches.
The two side surfaces also have the same dimensions, which are 17.5 inches by 4 inches.
Each of these sides has an area of 17.5 in × 4 in = 70 square inches.
The two end surfaces have the same dimensions, which are 10 inches by 4 inches. Each of these sides has an area of 10 in × 4 in = 40 square inches.
To find the total surface area of the box, we add up the areas of all six sides:
175 in² (top) + 175 in² (bottom) + 70 in² (side 1) + 70 in² (side 2) + 40 in² (end 1) + 40 in² (end 2)
Total surface area = 570 in².

Answers
Answer:
(a) \(Q_1=36.5,M=Q_2=41,Q_3=46\)
(b) \(IQR=9.5\)
(c) 15
Step-by-step explanation:
The given data set is
41, 52, 37, 44, 42, 38, 41, 48, 43, 39, 36, 55, 42, 35, 15, 52, 39, 50, 29, 30
Arrange the data in ascending order.
15, 29, 30, 35, 36, 37, 38, 39, 39, 41, 41, 42, 42, 43, 44, 48, 50, 52, 52, 55
Divide the data in four equal parts.
(15, 29, 30, 35, 36), (37, 38, 39, 39, 41), (41, 42, 42, 43, 44), (48, 50, 52, 52, 55)
Now,
\(Q_1=\dfrac{36+37}{2}=36.5\)
\(M=Q_2=\dfrac{41+41}{2}=41\)
\(Q_3=\dfrac{44+48}{2}=46\)
\(IQR=Q_3-Q_1=46-36.5=9.5\)
Range for outlier is
\([Q_1-1.5IQR,Q_3+1.5IQR]=[36.5-1.5(9.5),46+1.5(9.5)]\)
\(=[22.25,60.25]\)
