The data below shows the scores of two groups of ten students on a math quiz and a science quiz.
Math: 72, 92, 88, 67, 54, 58, 64, 76, 65, 72
Science: 84, 78, 56, 89, 54, 68, 75, 78, 84, 60
In this scenario, variability is defined as the mean absolute deviation. Based on the data which statement is true?
O The median score was greater for math, but the variability was greater for science.
OThe median score was greater for science, but the variability was greater for math
OBoth the median score and variability of the math scores are less than that of the science scores.
OBoth the median score and variability of the math scores are greater than that of the science scores.
Answer:
The median score was greater for science, but the range was greater for math.
Step-by-step explanation: I think I don’t now.
The statement "The median score was greater for math, but the variability was greater for science" is true
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
Calculate the mean absolute deviation (MAD) for both sets of scores. The MAD measures the average distance of each score from the mean of the data set.
For the math scores, the mean is:
(72 + 92 + 88 + 67 + 54 + 58 + 64 + 76 + 65 + 72) / 10 = 70.8
To calculate the MAD for the math scores, we need to find the absolute deviation of each score from the mean.
The sum of these absolute deviations is:
1.2 + 21.2 + 17.2 + 3.8 + 16.8 + 12.8 + 6.8 + 5.2 + 5.8 + 1.2 = 91
To calculate the MAD for the science scores, we need to find the absolute deviation of each score from the mean, and then calculate the average of these absolute deviations.
The sum of these absolute deviations is:
10.4 + 4.4 + 17.6 + 15.4 + 19.6 + 5.6 + 1.4 + 4.4 + 10.4 + 13.6 = 103.4
The MAD for the science scores is:
103.4 / 10 = 10.34
Therefore, the statement "The median score was greater for math, but the variability was greater for science" is true

the length of a rectangle is 6 meters more than its width. if the area of the rectangle is 135 square meters, find its dimensions, PLEASE explain and show steps
Answer:
length 15 width 9
Step-by-step explanation:
Then the length can be represented by the following expression: (x + 6)
Since area is equal to length times width, we can write the following equation for the area:
A = length * width
135 = (w + 6) * w
Now we can solve for w after using the distributive property and factoring:
135 = (w + 6) * w
135 = w^2 + 6w
0 = w^2 + 6w - 135
This factors to:
0 = (w + 15) (w -9)
w = -15 OR w = 9

Find the angle between the diagonal of a cube of side length 15 and the diagonal of one of its faces, so that the two diagonals have a common vertex. The angle should be measured in radians. (Hint: we may assume that the cube is in the first octant, the origin is one of its vertices, and both diagonals start at the origin.)
Answer:
the angle between the diagonal is 0.6155 RADIANS
Step-by-step explanation:
Given the data in the question
as illustrated in the image below;
O is [0,0,0]
B is [15,0,15]
E is [15,15,15]
Now to find angle BOE
vector OB = [15,0,15]
vector OE = [15,15,15]
OB.OE = [15,0,15].[15,15,15] = 15 × 15 + 15 × 15 = 450 = |OB||OE|cos[angleBOE]
|OB| = √(15² + 15²) = √(225 + 225) = √450
|OE| = √(15² + 15² + 15²) = √(225 + 225 + 225) = √675
so
Angle BOE = cos⁻¹ ( 450 / ( √450 × √675 )
Angle BOE = cos⁻¹ ( 0.81649 )
Angle BOE = 35.265°
Angle BOE = 0.6155 RADIANS
Therefore, the angle between the diagonal is 0.6155 RADIANS

Find part B
Answer:
b = 45 / 4 = 11 1 /4.
Step-by-step explanation:
We are dealing with a (30,60,90)-triangle, therefore z = 15 sqrt(3) / 2. So as well b = (15 sqrt(3) / 2) sqrt(3) / 2 = 45 / 4.

2x + 8y=30 y=2 solve for x
Answer:
x = 7
Step-by-step explanation:
2x + 8y=30
y=2
2x + 8(2) = 30
2x + 16 = 30
2x = 30 - 16
2x = 14
x = 14/2
x = 7

P= 2L+2W
P=2(12) +2(7) =38
Step-by-step explanation:
The width of a rectangle is 5 meters less than its length. The area is 84 square meters. Find the dimensions of the rectangle and the perimeter of the rectangle.
First it helps to draw a picture so draw a rectangle
Remember that area of a rectangle =Length times width and the perimeter is P= 2 times the length plus 2 times the width
So A=LW and P=2L+2W
84= area
L=length
W= length -5
L(L-5)=84 distribute the L and you have L2 -5L=84 now subtract 84 from both sides and get L2 �5L-84 next factor to get (L+7)(L-12) next set both to =0 (L+7)=0 (L+12)=0 solve for L
L=-7 and L=12 you can�t have a negative length so -7 is out. So L=12 now plug in to the original area equation
84=LW 84= 12w now divide both sides by 12 to isolate W, this gives you W=7
L=12 and W= 7
For perimeter use 12 for the length and 7 for width Remember that P= 2L+2W
P=2(12) +2(7) =38
