Answer:
Mean = $123
Standard deviation = 10190
Variance = 1698
Step-by-step explanation:
Mean=?
= sum of all numbers/ Total numbers
a = 93+173+107+125+56+163+144 / 7 = 861/7 = $123
Standard deviation=?
we know that = Sqareroot [ Sum (y)²] / N
we need deviation:
= x-a = y ; y²
= 93-123 = -30 ; 900
=173-123 = 50 ; 2500
=107-123 = -16 ; 256
=125-123 = 2 ; 4
=56-123 = -67 ; 4489
=163-123 = 40 ; 1600
=144-123 = 21 ; 441
Sum of y² = 10190.
= Square root [ 10190 / 7 ]
= 38.1
Variance = ?
= Sum ( y)² / N-1
= 10190 / ( 7-1)
= 10190 /6
= 1698
Answer:
Step-by-step explanation:
The order for FCFS is: 20->10->22->20->2->40->6->38.
Distance is
10+12+2+18+38+34+32 = 146
cylinders, so time is
146* 6 = 876 sec.
The order for elevator is:
20->20->22->38->40->10->6->2.
Distance is
0+2+16+2+30+4+4 = 58
cylinders, so time is
58 * 6 =348 msec.
The order for CCN is:
20->20->22->10->6->2->38->40.
Distance is
0+2+12+4+4+36+2 = 60
cylinders, so time is 60 * 6 =360 msec.
|x – 3| = 45; minimum angle: 45 degrees
|x – 45| = 3; minimum angle: 42 degrees
|x – 45| = 3; minimum angle: 45 degrees
The equation which can be used to determine the minimum and maximumoptimalangles of launch and the minimum angle that is still optimal is |x – 45| = 3 and 42 degrees respectively.
This is formed when two straight lines meet at a common endpoint and are also formed during intersection of planes.
In this scenario we were told the angle is within 3 degrees of 45 degrees which means the minimum angle is 45 degrees - 3 degrees = 42 degrees with the equation used to determine the minimum and maximum being |x – 45| = 3 as the maximum angle and deviation has to be present in the equation.

Answer: C |x – 45| = 3; minimum angle: 42 degrees
Step-by-step explanation:
Answer: L = 4 + w
A = 2P - 4
lw = 2(2l +2w) - 4
lw = 4(l + w) - 4
(w+4)w = 4 ( w+4+w) -4
(w +4)w = 4(2w + 4) - 4
w^2 + 4w = 8w + 16 - 4
w^2 + 4w = 8w + 12
w^2 - 4w - 12 = 0
( w - 6 )( w + 2 ) = 0
w - 6 = 0 ----> w = 6 ----> L=10 ---> P = 32 and A = 60
w + 2 = 0 ---> w = -2 <--- width cannot be negative; disqualified/rejected
