Question 11(Multiple Choice Worth 1 points)
(08.06 MC)
The following data shows the weight, in pounds, of 5 boxes:
3, 1, 2, 2, 2
What is the value of the mean absolute deviation of the weight of the boxes, and what does it represent about the weight of a box?
(A.) 0.4 pound; on average, the weight of a box varies 0.4 pounds from the mean of 2 pounds
(B.) 0.8 pound; on average, the weight of a box varies 0.8 pounds from the mean of 2 pounds
(C.) 0.4 pound; the weight of 50% of the boxes is greater than 0.4 pound
(D.) 0.8 pound; the weight of 50% of the boxes is greater than 0.8 pound
Answer:
c is the answer
Step-by-step explanation:
Answer:
Step-by-step explanation:
First put the numbers from least to greatest: 1, 2, 2, 2, 3 2 is the mean.
Then you determine the distance each data value is from the mean.
1, 2, 2, 2, 3
1, 0, 0, 0, 1
Calculate the mean of the distances: 1 + 0 + 0 + 0 + 1 = 2
Then divide: 2 divided by 5 = 0.4
So your answer is 0.4 pound; on average, the weight of a box varies 0.4 pounds from the mean of 2 pounds

How many pieces are there on the rubix cube
26 pieces
There are 26 pieces in total, and the cube has 8 corners and 6 centers.
answer choices:
A. 42 °
B. 47°
C. 48°
D. 41°
can some one help me please
Answer:
D. 41°
Step-by-step explanation:
[tex](3x + 9) \degree = 132 \degree \\ (vertical \: \angle s) \\ 3x + 9 = 132 \\ 3x = 132 - 9 \\ 3x = 123 \\ x = \frac{123}{3} \\ x = 41 \\ \\ \because m\angle QRS =x\degree \\\therefore m\angle QRS = 41\degree [/tex]
Your body mass index (BMI) is your weight in kilograms divided by the square of your height in meters. Many online BMI calculators allow you to enter weight in pounds and height in inches. High BMI is a common but controversial indicator of overweight or obesity. A study by the National Center for Health Statistics found that the BMI of American young men (ages 20 to 29) is approximately normal with mean 26.8 and standard deviation 5.2. People with BMI less than 18.5 are often classed as "underweight." What percent of young women are underweight by this criterion? Sketch and shade the area of interest under a Normal curve.
Answer:
5.5227%
Step-by-step explanation:
Z score formula = (x-μ)/σ
where x is the raw score = < 18.5
μ is the population mean = 26.8
σ is the population standard deviation = 5.2
For x < 18.5
z = 18.5 - 26.8/5.2
z = -1.59615
Probability value from Z-Table:
P(x<18.5) = 0.055227
Converting to percentage
= 0.055227 × 100
= 5.5227%
Therefore, the percentage of young women that are underweight by this criterion is 5.5227%
What is the gradient?
Answer:
Gradient = 2
Step-by-step explanation:
Gradient of a line = Slope of the line
Since, slope of a line passing through two points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Given line in the graph passes through two points (1, 0) and (2, 2)
Therefore, slope or gradient of the line = [tex]\frac{2-0}{2-1}[/tex]
= 2
Gradient = 2 will be the answer.

Answer:
<YXZ and <TUS
Step-by-step explanation:
Alternate exterior angles are angles that are found on opposite sides of a transversal and are found just outside each parallel line that the transversal crosses.
Looking at the diagram given and considering the options available, the angles that are alternate exterior angles are:
<YXZ and <TUS
A triangle has vertices T(-2,4), E(6,2), and D(1,-1). Is ATED a right triangle?
No, this is not a right triangle.
Yes, because ED is perpendicular to DT which makes a right angle.
Yes, because TE is perpendicular to DT which makes a right angle.
Yes, because TE is perpendicular to ED which makes a right angle.
Answer:
B. Yes, because ED is perpendicular to DT which makes a right angle.Step-by-step explanation:
Plot the given points and connect in pairs to get a triangle.
Visually we can say it is a right triangle as legs TD and ED seem perpendicular.
Let's confirm this by finding the slopes.
Slope of TD:
m = (-1 - 4)/(1 -(-2)) = -5/3Slope of ED:
(-1 - 2)/ (1 - 6) = -3/-5 = 3/5Product of the slopes is:
-5/3*3/5 = -1This confirms DT⊥ED

Lines a and b are parallel and lines e and f are parallel. Vertical and parallel lines a and b are intersected by horizontal lines e and f. At the intersection of lines a and e, the top left angle is angle 1 and the top right angle is angle 2. At the intersection of lines b and e, the bottom left angle is angle 3. At the intersection of lines b and f, the uppercase right angle is angle 4 and the bottom left angle is angle 5. If m1 = 89°, what is m5? 1 89 91 179
Answer:
answer is c

Solve using the tangent formula(real answers only please)
9514 1404 393
Answer:
21.07
Step-by-step explanation:
The tangent ratio is ...
Tan = Opposite/Adjacent
For the given values, this is ...
tan(36°) = x/29
Solving for x, we have ...
x = 29·tan(36°)
x ≈ 21.07
Solve by substitution: y=3x and x+y=-32
Answer:
X=-8, y=-24
Step-by-step explanation:
Y=3x
x+y=-32
substitute value of y (3x) from first equation to the second equation
x+3x=-32
4x=-32
x=-8
solve for y by putting value of x (-8) into either equation
y=3x
y=3(-8)
y=-24
0r
x+y=32
-8+y=-32
y=-24
