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

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.

Jose has scored 166 points on his math tests so far this semester. To get an A for the semester, he must
score at least 248 points.
Part 1 out of 2
Enter an inequality to find the minimum number of points he must score on the remaining tests in order to
get an A. Let n represent the number of points Jose needs to score on the remaining tests.
The inequality is
+ n (select)
Next
Answer: 166 + n >= 248. <-- We use >= symbol since at least means greater than or equal to.
166 + n >= 248
n >= 82

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

India is the second most populous country in the world, with a population of over 1 billion people. Although the government has offered various incentives for population control, some argue that the birth rate, especially in rural India, is still too high to be sustainable. A demographer assumes the following probability distribution for the household size in India. Household Size Probability 1 0.05 2 0.09 3 0.12 4 0.24 5 0.25 6 0.12 7 0.07 8 0.06 a. What is the probability that there are less than 5 members in a household in India
Answer:
[tex]P(At\ least\ 5) = 0.50[/tex]
Step-by-step explanation:
Given:
[tex]\begin{array}{cc}{Size} & {Probability} & {1} & {0.05} & {2} & {0.09} \ \\ {3} & {0.12} & {4} & {0.24} & {5} & {0.25} & {6} & {0.12} & {7} & {0.07} & {8} & {0.06}\ \end{array}[/tex]
Required
Determine the probability that there are at least 5 members in a household
At least 5 means 5 to 8.
So, the probability is:
[tex]P(At\ least\ 5) = P(5) + P(6) + P(7) + P(8)[/tex]
[tex]P(At\ least\ 5) = 0.25 + 0.12 + 0.07 + 0.06[/tex]
[tex]P(At\ least\ 5) = 0.50[/tex]
The probability is 0.50

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
