1. The set of data below represents test scores for 20 students on a final exam.
What are the outliers in the data set?
[Hint: Lower Limit = Q 1 – 1.5(IQR) ; Upper Limit = Q 3 + 1.5(IQR)]
2. The set of data below represents test scores for 20 students on a final exam. What is the value of Q 1?
3. The set of data below represents test scores for 20 students on a final exam. What is the value of Q 3?
Answer:
1. D. 20, 30, and 50
2. A. 86
3. B. 94
Step-by-step explanation:
1. To find the outliers of the data set, we need to determine the Q1, Q3, and IQR.
The Q1 is the middle data in the lower part (first 10 data values) of the data set (while the Q3 is the middle data of the upper part (the last 10 data values) the data set.
Since it is an even data set, therefore, we would look for the average of the 2 middle values in each half of the data set.
Thus:
Q1 = (85 + 87)/2 = 86
Q3 = (93 + 95)/2 = 94
IQR = Q3 - Q1 = 94 - 86
IQR = 8
Outliers in the data set are data values below the lower limit or above the upper limit.
Let's find the lower and upper limit.
Lower limit = Q1 - 1.5(IQR) = 86 - 1.5(8) = 74
The data values below the lower limit (74) are 20, 30, and 50
Let's see if we have any data value above the upper limit.
Upper limit = Q3 + 1.5(IQR) = 94 + 1.5(8) = 106
No data value is above 106.
Therefore, the only outliers of the data set are:
D. 20, 30, and 50
2. See explanation on how to we found the Q1 of the given data set as explained earlier in question 1 above.
Thus:
Q1 = (85 + 87)/2 = 86
3. Q3 = (93 + 95)/2 = 94

Step-by-step explanation:
0.2 x 6 = 1.2
Answer:
1.2
Step-by-step explanation:
0.12 looks like the correct answer but its not because if you look at the problem its 0.2 and 0.12 is smaller than 0.2 so its 1.2 because 0.2 x 6 = 1.2

Step-by-step explanation:
Square pyramid A and square pyramid B are similar. Their respective heights are 6 and 15 inches. The volume of pyramid B is 312.5 cubic inches. What is the volume of pyramid A?
The volume of pyramid A is 20 cubic inches.
Given that:
Height of pyramid of A and B are 6 and 15 inches, respectively.
Since square pyramid A and square pyramid B are similar, their corresponding sides are proportional.
Let the volume of pyramid A be V and the scale factor between the two pyramids be k.
The volume of a pyramid is given by V = (1/3) × base area × height.
Since the base of pyramid B is k times the base of pyramid A, and the height of pyramid B is also k times the height of pyramid A, we can set up the following relationship:
V(B) = k³ × V(A)
Given that the height of pyramid A is 6 inches and the height of pyramid B is 15 inches, we can calculate the scale factor k as follows:
k = height of B / height of A = 15 / 6 = 2.5
Now, we know the scale factor k, and we are given the volume of pyramid B as 312.5 cubic inches. We can find the volume of pyramid A:
V(B) = k³ × V(A)
312.5 = 2.5³ × V(A)
312.5 = 15.625 × V(A)
Now, solve for V(A):
V(A) = 312.5 / 15.625
V(A) = 20
The volume of pyramid A is 20 cubic inches.

Answer:
Mean - 89
Median - 90.5
Mode - 89 or 92
Q1 - 84.5
Q3 - 96.5
IQR - 12
Step-by-step explanation:
A mean is an average. Just add all numbers then divide by how many numbers there are.
A median is a middle. Just arrange the numbers from smallest to largest and locate the middle value.
A mode is the number that appears most often. Count how many of each number there is.
Q1 is the middle of the lower half of the data.
Q3 is the middle of the upper half of the data.
IQR is the difference between Q3 and Q1. (subtract)

Solve for x (5x +40) A. AB. BC, AC B. BC. AC. AB C. AC. AB. BC (7x+8) (10x) с A D. BC. AB. AC Which of the following lists the sides in order from shortest to longest?
Answer:
D
Step-by-step explanation:
The shortest side is the side opposite the smallest angle, the longest side is opposite the largest angle.
First find the measure of the angles in the triangle.
The sum of the 3 angles = 180° then
5x + 40 + 10x + 7x + 8 = 180
22x + 48 = 180 ( subtract 48 from both sides )
22x = 132 ( divide both sides by 22 )
x = 6
Then
∠ A = 7x + 8 = 7(6) + 8 = 42 + 8 = 50°
∠ B = 5x + 40 = 5(6) + 40 = 30 + 40 = 70°
∠ C = 10x = 10(6) = 60°
The shortest side is opposite ∠ A , that is BC
The longest side is opposite ∠ B , that is AC
The sides in order from shortest to longest are
BC, AB, AC → D

Faith purchases a car for $27,500. The
value of the car will depreciate each
year at a rate of 12.4%. What is the
approximate equivalent monthly
depreciation rate, to the nearest tenth
of a percent?
Help please tell the explanation I’ll give brainleist
Answer:
To the nearest tenth of a percent, the approximate equivalent monthly depreciation rate is 1.0%
Step-by-step explanation:
From the question, we have a per annum decrease of 12.4%
what this mean is that, yearly, we expect a decrease of 12.4%
To get the monthly decrease value, we have to divide this given value by the number of months in a year which is 12
Thus, we have it that;
12.4%/12
= 1.0%
To the nearest tenth, the monthly decrease percentage is 1.0%

The angles in a triangle are in the ratio 1 : 2 : 3
Show that the triangle is a right-angled triangle
Answer:
see explanation
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 = 6 parts
Divide 180° ( sum of angles in a triangle ) by 6
180° ÷ 6 = 30° ← value of 1 part of the ratio , then
2 parts = 2 × 30° = 60°
3 parts = 3 × 30° = 90°
The angles in the triangle are 30°, 60°, 90°
Then the triangle is right angled
Answer:
The angles are 30°, 60° and 90°.Step-by-step explanation:
Hint : sum of the angles in triangle = 180°.The triangle is a right-angled triangle.Answer:Let missing angles be [tex]x[/tex], [tex]2x[/tex].
As the triangle is right-angled triangle.
[tex]x + 2x + {90}^{o} = {180}^{o} [/tex]
[tex]3x = {180}^{o} - {90}^{o} [/tex]
[tex]3x = {90}^{o} [/tex]
[tex]x = \frac{90 ^{o} }{3} [/tex][tex]x = {30}^{o} [/tex]
[tex]2x = 30 \times 2 \\ = {60 }^{o} [/tex]
Check:30° + 60° + 90° = 180°.Hope it is helpful....
