Answer:
It has 2 significant figures, which I assume is what you meant.
Answer:
x and y
Step-by-step explanation:
Answer:
Step-by-step explanation:
2x + 3y = 12
subtract 2x from both sides
3y = -2x + 12
divide both sides by 3
y = -2/3x + 4
Answer:
3600 hours
Step-by-step explanation:
let total life time of t four transistors T = X1 + X2 + X3 + X4 (where X1,X2,X3 and X4 are life time of individual transistors
mean of the length of time that four transistors will last =E(T)=E(X1 + X2 + X3 + X4)
=E(x1) + E(x2) + E(x3) + E(x4) =900+900+900+900 =3600
and standard deviation of total time =SD(T)=sqrt(Var(T)) = sqrt(Var(X1) + Var(x2) + Var(x3) + Var(x4))
where sqrt means the square root
=sqrt(302+302+302+302) =sqrt(3600) =60
Answer:
14
Step-by-step explanation:
319 / 11 = 29
(Quick Check) 11 x 29 = 319
----------------------------------------------
So..
406 / 29 = 14
(Quick Check) 14 x 29
I hope I helped.
