Answer:

Step-by-step explanation:

Given is the table shows the number of hours of sleep all members of a theater group got the night before their musical.

8 8.5 8 7.5 9 9

8 7 7 9 8 8

8 7 7 8 7.5 8.5

7.5 8 8.5 9 8 7.5

Total all these entries and divide by 20 to get population mean.

Sum = 50+47+46+48.5=191.5

Population mean = 191.5/24 =7.98

Sample size is 10

Sum =84

Sample mean =8.4

Answer:

I take it you mean the average gallons lost an hour, in which case you would do 58,432.4 - 56,475.2 to get 1,597.2 to which you divide by 2 getting your final answer of 978.6

An acrobat of mass m slides down a vertical rope of height h. For the first three quarter of her descent she grips the rope with

Maksim231197 [3]

Using the work-energy theorem would be best in solving this problem. The net work on an object causes a change in the kinetic energy of the object, based from the work-energy theorem. For this, the formula for net work = change in kinetic energy = final kinetic energy - initial kinetic energy.

So, first sliding distance covered 3/4 with a net force 1-5/9 = 4/9 and w (w stands for weight of acrobat)

Therefore, work done = 4/9 * 3/4
In the next step, the distance to be covered is 1/4.
So, let the new frictional force required be X w
Therefore, net force upward = (X - 1) w
Thus, work to be done = (X - 1) * 1/4 w---------(2)
Equating X = 1 + 4/3 = 7/3

So, the frictional force that she must produce in the last quarter has to be 7/3 times her weight.

Frankie wants to build a path from one corner of his yard to the opposite corner. His yard measures 20 ft. x 32 ft. What will be

riadik2000 [5.3K]

Frankie's yard is a rectangle with the longer side = 32ft and the shorter side = 20ft. You want to find the length of the diagonal going through the rectangle. In essence, you basically have a triangle with two sides, one 32ft, the other 20ft, and you're looking for the hypotenuse.

Let's call a=32, b=20, and you're looking for the hypotenuse c. Use the Pythagorean theorem:
${a}^{2} + {b}^{2} = {c}^{2}$
Plug the numbers in to find c, the length of your path! So
$\sqrt{{32}^{2} + {20}^{2}} = 37.7$
