Answer:
ok so if you call the first circle x, the second circle is 90% of x, therefore the third circle is 90% of 90% of x, which is .81 of x, sooooo the third circle is 81% of the 1st
I'm in rsm too, so i understand ur difficulty
Step-by-step explanation:
Answer:



If we Trim the top and bottom 14% from the data we need to eliminate 32*0.14 =4.48 so we need to eliminate approximately 5 values from each tail and we got:
16 20 20 22 25 27 29 31 32 32 32 34 34 35 36 36 37 38 39 41 42 43
And the mean calculated from this data is :

Step-by-step explanation:
For this case we have the following data:
27 11 36 22 36 12 35 37 50 16 31 45 48 14 20 34 46 15 25 41 34 39 42 29 32 32 8 32 20 38 43 45
And we can calculate the mean with this formula:

And replacing we got:

The mid range is calculated with this formula:

And replacing we got:

Since the sample size is n =32 we can calculate the geometric mean with this formula:

For the trimmed mean we need to sort the dats on increasing order and we got:
8 11 12 14 15 16 20 20 22 25 27 29 31 32 32 32 34 34 35 36 36 37 38 39 41 42 43 45 45 46 48 50
If we Trim the top and bottom 14% from the data we need to eliminate 32*0.14 =4.48 so we need to eliminate approximately 5 values from each tail and we got:
16 20 20 22 25 27 29 31 32 32 32 34 34 35 36 36 37 38 39 41 42 43
And the mean calculated from this data is :

=(140+4) / 8
=(144/8) + (4/8)
=18 + 2

Answer:
volume of the tank be when the sensor turns on = 92.316 ft³
Step-by-step explanation:
Volume of a cylinder = πr²h
Pi = π = 3.14
Radius = r = 7 ft
Height = h = 3 ft
Volume of a cylinder = πr²h
= 3.14 × 7² × 3
= 3.14 × 49 × 3
= 461.58 ft³
The tank comes equipped with a sensor to alert the farmer to fill it up when the water falls to 20% capacity.
volume of the tank be when the sensor turns on = 20% of Volume of a cylinder
= 0.20 * 461.58 ft³
= 92.316 ft³
volume of the tank be when the sensor turns on = 92.316 ft³
Answer:
k = - 6.6667
Step-by-step explanation:
this is quite very simple to begin. I would encourage you take other practice questions similar to help with understanding it.
let us begin.
Given that ;
dT/dt = k ( Tm - T) where Tm is the temp of the medium
dT/dt = 5 degrees Celsius per minute when T = 70
so we have that, 5 = k ( 25 - 70)
remember to convert 5 degree celsius per minute to seconds
we have that;
5*60(sec) = k ( 25 - 70)
k = 5*60 / ( 25 - 70)
k = - 6.6667
note K is negative because we consider it for cooling process (temp decreasing).
cheers i hope this helps!!!
