Answer:

C lower quartile: 146 upper quartile: 129.5

Step-by-step explanation:

101, 111, 117, 121, 122, 126, 133, 149 Order numbers from least to greatest and find the median.

Median=121.5 The middle is between 121 and 122, so the median is 121.5

111+117 /2 =114 Find the lower quartile by finding the median of the numbers below the overall median. The median of the lower set of data is between 111 and 117, so the lower quartile is 114

126+133 /2 =129.5 Find the upper quartile by finding the median of the numbers above the overall median. The median of the upper set of data is between 126 and 133, so the upper quartile is 129.5

Answer:

The correct option is C

Step-by-step explanation:

A: We know that the lower quartile is 144, and the upper quartile is 129.5 is you add them all up it is going to equal 273.3. So we know that A can now be crossed out.

B: We know that the lower quartile is 146, and that means the upper quartile is 136.5. So adding all of these numbers up we ill get 282.5 So now <u>B can be crossed out</u>

C: The lower quartile is 114 and the upper quartile is 129.5 and when we add those two numbers up we are going to get 243.5. So we are going to keep this number

D: For the last one we know the lower quartile is 214 and upper is 129.5, and when we add this we get 343.5. So we can cross this out and<u> the only one we have left is going to be C</u>

<u>Hope this help's</u>

faust18 [17]
By graph of object A the rate of change is estimated at 17/6.
Object B's rate of change is 10/3=20/6.

Comparing object A to object B:
17/6 <20/6

Object B is faster by:
17/6x=20/6
(6/17)(17/6)x=(20/6)(6/17)
x=20/17≈1.18

B)
Object B by a factor of 1.19

Since I made an estimation from graph of object A , my solution is off by. 01 but it is the closest I can get. The solution B is correct.

Farmer Joe has his horses in a rectangular pen. The length of the pen is 10 feet longer than three times its width. The total fe
Evgen [1.6K]

Answer:

The width of the garden is 100 feet.

Step-by-step explanation:

The formula for the perimeter of a rectangle is 2(L+W) where L = length and W = width.

Since we know the perimeter (the fence that surrounds the garden) is 820 feet and the length of the pen is 10 feet longer than 3 times its width, we can set an equation and solve for the width:

L = 10 + 3W

So substitute 10 + 3W for L in the equation:

2[(10 + 3W) + W) = 820

2(10 + 4W) = 820

10 + 4W = 410

4W = 400

W = 100

Therefore, the width of the garden is 100 feet.

A cylindrical tank of radius 5 ft and height 9 ft is two-thirds filled with water. Find the work required to pump all the water
Oduvanchick [21]

Answer:

130.826 kilojoules

Step-by-step explanation:

The Work required to pump water = pgV

Where, p = density of water = 1000 kg/m³

g = acceleration due to gravity = 9.81ms-¹

V = volume of water

Since, radius r = 5 ft and height h = 9ft

Volume of water in the cylindrical tank = (2/3)πr²h

V = (2/3)π *5²*9 = 471.24 ft³ = 471.24 * 0.0283m³ = 13.336m³

Work required = 1000*9.81*13.336

W = 130.826 KJ

Therefore, the work required to pump water 2/3 of the volume of the cylindrical tank = 130.826 kilojoules.
