Step-by-step explanation:
Answer:
88 centimeters is the diameter of the cilinder
Step-by-step explanation:
The pressure on both ends of the lift must be the same. Assuming the piston is cilindrical, its area will be A=π*r² where r is half the diameter
Since pressure P=F/A And P1=P2
F1=2000kg.g
A1=π*r²
F2=25kg.g
A2=π*0.05²
2000/(π*r²)=25/(π*0.05²)
and we solve for A1
r²=2000*0.05²/25

r=
20*0.05/5=0.44m or 44cm
This is the radius, meaning that the diameter will be twice this number
Answer: The percent of red lights last between 2.5 and 3.5 minutes = 95.44% approx.
Step-by-step explanation:
Given: Mean time = 3 minutes
standard deviation = 0.25 minutes
The probability of red lights last between 2.5 and 3.5 minutes :-

The percent of red lights last between 2.5 and 3.5 minutes = 95.44% approx.

it’s the third one
Step-by-step explanation:negatives are never higher than numbers without negatives

The system of equations don't have any solutions due to the exact same x-terms.
For this both system of equations, the answer is A.
The x-terms are the same for the equation to be false.
The constant, however, is indeed different as shown in the equation.
