The table below shows data from a survey about the amount of time high school student spent reading in amount of time spent watching videos each week (without reading). Which response best describes outliers in the data sets?
A. neither data set has suspected outliers
B. The range of data is too small to identify outliers
C. video has a suspected outlier in the 26-hour value
D. due to the narrow range of reading compared to video the video values of 18, 21, and 26 are all possible outliers
Answer:D
Step-by-step explanation:
Neither data set has suspected outliers response best describes outliers in the data sets.
Option A is correct.
What is IQR?The IQR describes the middle 50% of values when ordered from lowest to highest. To find the interquartile range (IQR), first find the median (middle value) of the lower and upper half of the data. These values are quartile 1 (Q1) and quartile 3 (Q3). The IQR is the difference between Q3 and Q1.
According to question
Reading:
Median = [tex]\frac{7+12}{2}[/tex] = 9.5
[tex]Q_{1}[/tex] = 5 × 25% + 7 × 75% = 6.5
[tex]Q_{3}[/tex] = 14 × 25% + 12 × 75% = 12.5
IQR is the difference between Q3 and Q1
IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 12.5 - 6.5 = 6
[tex]Q_{1}[/tex] - 1.5 IQR = 6.5 - 1.5 × 6 = -2.5 < Min = 5
[tex]Q_{3}[/tex] + 1.5 IQR = 6.5 + 1.5 × 6 = 15.5 > Max = 15
So no outlier in reading
Video :
[tex]Q_{1}[/tex] = 7 × 75% + 4 × 25% = 6.25
[tex]Q_{3}[/tex] = 21 × 25% + 18 × 75% = 18.75
IQR is the difference between Q3 and Q1.
IQR = [tex]Q_{3}[/tex] - [tex]Q_{1}[/tex] = 18.75 - 6.25 = 12.5
[tex]Q_{1}[/tex] - 1.5 IQR = 6.25 - 1.5 × 12.5 = -12.5 < Min = 1
[tex]Q_{3}[/tex] + 1.5 IQR = 18.75 + 1.5 × 12.5 = 37.5 > Max = 26
So no outlier in video
So neither data set has suspected outliers.
Option A is correct.

The variables x and y are proportional. Use the values to find the constant of proportionality. Then write an equation that relates x and y.
When y=72 and x=3.
K = ?
y = ?
Answer:
k = 24, y = 24x
Step-by-step explanation:
Given x and y are proportional then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when y = 72, x = 3 , then
72 = 3k ( divide both sides by 3 )
k = 24
y = 24x ← equation of proportion

Answer:
b) 180 cm²
Step-by-step explanation:
find area of square = 6 x 6 = 36
find area of one triangle = 1/2(6)(12) = 3(12) = 36
There are 4 congruent triangles, so 36 x 4 = 144
36 + 144 = 180

11. The slope of a line is 1/5. Label the two right
triangles with dimensions that would allow the
triangles to lie on the same line.
Answer:
Step-by-step explanation:
If the slope is 1/5, we can interpret this as rise/run = 1/5. We could (if we wished to do so) find the hypotenuse by using the Pythagorean Theorem:
hypo = +sqrt( 1^2 + 5^2)
In this case we dilate the triangle defined by the slope 1/5:
2/10, 1/10/(1/2), 10/50, etc., all represent right triangles whose hypotenuses lie on the same line (the line with slope 1/5).
The two right triangles are shown in the graph
What are coordinates?The coordinates in rectangular cartesian system are of the form -
(x, y)
where -
{x} - distance along x - axis.
{y} - distance along y - axis.
Given is the slope of the line as - {m} = 1/5.
Refer to the graph attached. The line -
y = (1/5)x
is plotted. It can be seen that (0, 0) and (10, 2) lie on the line. For two right triangles to lie on the same line, draw two perpendiculars from point (10, 2) along the {x} axis and {y} axis. Refer to the triangles shown in the graph.
Therefore, two right triangles are shown in the graph.

Find the distance between C(-5,4) and Q(2,0)
9514 1404 393
Answer:
√65 ≈ 8.06
Step-by-step explanation:
The distance formula is used for the purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((2 -(-5))² +(0 -4)²) = √(7² +(-4)²) = √(49 +16)
d = √65 ≈ 8.0622577
The distance between C and Q is √65, about 8.06 units.
