Answer:
The data is more spread out so their is a greater variability in the data.
Step-by-step explanation:
The Mean absolute deviation is large, then the data is more spread out and there is greater variability in the data.
What is mean absolute deviation?Mean absolute deviation is "collected data set is the average of absolute deviations from the center point of the data set".
According to the question,
Formula for Mean absolute deviation = summation of ( absolute value of xₙ - x⁻ divided by number of data values), where ' xₙ' is the input data values and 'x⁻ ' is mean of the given data values .
When the mean absolute deviation is large number then the data spread out more and the variability is greater in data.
Hence, the Mean absolute deviation is large then there is greater variability in the data.

Find the volume of a cone that has a radius of 8 meters and a height of 9 meters. Use 3.14 for pi
Answer:
Volume of cone = 1/3 Area of base × height
= 1/3× πr² × h
= 1/3×3.14×8²×9
= 602.88 m³
Answer:
602.44 cubic meters[tex] \: [/tex]
Step-by-step explanation:
In the question, it is given that a cone has a radius of 8 meters and a height of 9 meters and we have to find the volume of the cone.
[tex] \: [/tex]
To Find the volume of the cone, we must know this formula :
[tex] \\{\longrightarrow{ \qquad{\underline{\boxed {\pmb{\frak { Volume_{(cone) }= \dfrac{1}{3} \: \pi {r}^{2}h }}}}}}} \\ \\[/tex]
Where,
r refers to the radius of the cone.h refers to the height of the cone.Now, we will substitute the values in the formula :
[tex] \\ {\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times 3.14 \times {(8)}^{2} \times 9 }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times 3.14 \times 64 \times 9 }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times 3.14 \times 576 }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1}{3} \times 1808 .64 }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\sf { Volume_{(cone) }= \dfrac{1808 .64}{3} }}}}}}} \\ \\[/tex]
[tex]{\longrightarrow{ \qquad{{ {\pmb{\frak { Volume_{(cone) }= 602.88 }}}}}}} \\ \\[/tex]
Therefore,
The volume of the cone is 602.88 m³A ball is thrown into the air from a height of 4 feet with an initial velocity of 63 ft/sec. The function that models this situation is h(t) = –16t2 + 63t + 4, where t is measured in seconds and h is the height in feet.
(a) What is the height of the ball after 2 seconds?
(b) What is the maximum height of the ball?
(c) When will the ball hit the ground?
(d) What domain makes sense for the function?
#1
h(2)-16(2)²+63(2)+4-16(4)+126+4-64+13066ft#2
Convert to Vertex form of parabola y=a(x-h)²+k
y=-16t²+63t+4We need calculator now
y=-16(t-1.969)²+66.02On comparing
Vertex=(h,k)=(1.969,66.02)As a is negative so parabola is opening downwards hence vertex is maximum
Max height=66.02ft#3
When h(t) is 0 ball hits the ground
-16t²+63t+4=0-16t²-t+64t+4=0On solving we get t=-1/16 or 4
Take it positive
t=4sAt 4s it reach the ground
#4
Domain is set of all t values (Time axis)
Here
ball starts from 0s and hits 0 again at 4s
So domain=[0,4]
Answer:
(a) 66 ft
(b) 66.015625 feet
(c) 4 s
(d) 0 ≤ t ≤ 4
Step-by-step explanation:
[tex]h(t)=-16t^2+63t+4[/tex]
Part (a)
[tex]t=2 \implies h(2)=-16(2)^2+63(2)+4=66[/tex]
Therefore, the height of the ball after 2 seconds is 66 feet
Part (b)
The maximum height will be the turning point of the parabola.
To find the turning point, differentiate the function:
[tex]\implies h'(t)=-32t+63[/tex]
Set it to zero:
[tex]\implies h'(t)=0[/tex]
[tex]\implies-32t+63=0[/tex]
Solve for t:
[tex]\implies 32t=63[/tex]
[tex]\implies t=\dfrac{63}{32}=1.96875[/tex]
Input found value of t into the function and solve for h:
[tex]\implies h(1.96875)=-16(1.96875)^2+63(1.96875)+4=66.015625[/tex]
Therefore, the maximum height of the ball is 66.015625 feet
Part (c)
The ball will hit the ground when h(t) = 0
[tex]\implies -16t^2+63t+4=0[/tex]
[tex]\implies 16t^2-63t-4=0[/tex]
[tex]\implies 16t^2+t-64t-4=0[/tex]
[tex]\implies t(16t+1)-4(16t+1)=0[/tex]
[tex]\implies (t-4)(16t+1)=0[/tex]
[tex]\implies t=4, t=-0.0625[/tex]
As time is positive, t = 4s only
Part (d)
As time is positive, and the ball hits the ground when t = 4 s, the domain should be restricted to: 0 ≤ t ≤ 4

Jerry hiked along a path. From his starting position, he hiked downhill to a valley where the elevation dropped 25 meters below his starting position. Then, he hiked up to a hill that was 40 meters higher than the valley.
The following equation describes this situation.
-25 + 40 = 15
CHOOSE 1 ANSWER
1. Jerry hiked a total of 15 meters
2. the hill was 15 meters higher than the elevation of his starting point
3. None of the above
Answer:
15 represents where Jerry is after the elevation dropped 25 meters and then rose 40 meters.
Step-by-step explanation:
It's given that Jerry hiked downhill to a valley where the elevation dropped 25 meters below his starting position. Then, he hiked up to a hill that was 40 meters higher than the valley
Hiked downhill = 25 meters
Hiked up = 40 meters
The given equation is
Here, hiked downhill represented by negative sign and hiked up resents by positive sign.
So, 15 represents that Jerry hiked up 15 meters from his starting position.
(2, the hill was 15 meters higher than the elevation of his starting point)
Answer:
2.
Step-by-step explanation:
The hill was -25 + 40 = 15 meters highe than starting point.

I need answers with explanations for each one.
Step-by-step explanation:
the sum of all angles around a single point on one side of a line is always 180° (a line can always be seen as the diameter of an imaginary circle, so each side corresponds to 180°).
the angles on one side of a line crossed by a second line are mirrored but otherwise exactly the same as on the other side of the line.
a parallel line crossing a third line must have the exact same angles with this third line as the other parallel line. otherwise they would not be parallel. you can say a parallel line mimics the exact same behavior as the other line it is parallel to.
so,
c = 180 - 35 = 145°
a = c = 145°
b = 35°
d = 180 - 110 = 70°
e = d = 70°
f = 110°
g = 180 - 125 = 55°
i = g = 55°
h = 125°
j = 180 - 130 = 50°
m = j = 50°
o = k = d = e = 70° (as this line crosses 2 levels)
l = f = 110°
n = 180 - m - o = 180 - 50 - 70 = 60°
s = 180 - 23 = 157°
p = 23°
r = 68°
q = 180 - p - r = 180 - 23 - 68 = 89°
t = 180 - 68 = 112°
v = w = z = 132° (as this line crosses 2 levels)
A = 180 - 132 = 48°
y = x = u = A = 48°
B = 180 - 39 - 47 = 94°
D = B = 94°
C = 39 + 47 = 86°
E = 47°
F = B + 39 = 94 + 39 = 133°
The radius of a cylindrical water tank is 6.5ft, and its height is 17ft. What is the volume of the tank?
Use the value 3.14 for [tex]\pi[/tex], and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.
Answer
718.25 pi or 2,256.4489
Step-by-step explanation:
The volume formula for cylinders is V=pi * r^2 * h
So plug in your numbers!
r=6.5 h=17
pi times 6.5^2 times 17 = pi*718.25 or 2,256.4
A landscaping company placed two orders with a nursery. The first order was for 13 bushes and 4 trees, and totaled $327.50. The second order was for bushes and 2 trees, and totaled $142.96.

The system of equations that Sam can use is given by:
A 13b + 4t =327.50, 6b + 2t = 142.96
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
Variable b: Cost of a bush.Variable t: Cost of a tree.The first order was for 13 bushes and 4 trees, and totaled $327.50, hence:
13b + 4t = 327.50.
The second order was for 6 bushes and 2 trees, and totaled $142.96, hence:
6b + 2t = 142.96.

A fruit company delivers its fruit in two types of boxes: large and small. Delivery of 8 large boxes and 4 small boxes has a total weight of 173 kilograms. Delivery of 3 large boxes and 2 small boxes has a total weight of 68 kilograms. How much does each type of box weigh?
Weight of each large Box: ?
Weight of each Small Box: ?
Answer:
x = 18.5 (large) , y = 6.25 (small)
Step-by-step explanation:
Let's start by assigning variables to each type of box.
The large box we will call "x"
The small box we will call "y"
We know that 8x + 4y = 173 (kilograms)
And 3x + 2y = 68 (kilograms)
Since we set up a system of equations, we can now use elimination, by multiplying the entire bottom equation by -2, to get rid of the "y" variable.
8x + 4y = 173
3x(-2) + 2y(-2) = 68(-2)
-6x + -4y = -136 (side note: notice how the "y"'s would cancel each other out because -4y + 4y equals 0)
Add equations together:
2x = 37
x= 18.5
Now that we have x, just substitute it into any of the equations to get y.
You will see that y = 6.25
