Answer:
1/50
Step-by-step explanation:
Probability that both engines fail = Failure rate of both engines
= 1/100 + 1/100
= 2/100
= 1/50
They will both next happen in 2040
Answer
y=120
Step-by-step explanation:
2.5 ->100
3 -> y
y=(3*100)/2.5
y=120
We have that
<span>x - y = 4-------> multiply by -1-----> -x+y=-4-----> equation 1
x+ 2y = 4------> equation 2
add equation 1 and equation 2
-x+y=-4
x+2y=4
-----------------
0+3y=0-----> y=0
x+2y=4------> x+0=4------>x=4
the solution is the point (4,0)</span>
Answer:
0.25*4=1 the square root is 1.
Step-by-step explanation:
4 1/4 hrs if you take the 1/4 and you 4 divide by 1 which will give you 0.25. Then you take the 0.25*4=1. you take that 1 and it becomes the square root of the whole problem.
