Answer:
x+y=5
Step-by-step explanation:
y=-x+5
add x to both sides
x+y=5
Answer: C) (9000x5) + (300x5) + (8~5) + (1x5)
Step-by-step explanation:
First Find what 9381 times 5 is.
9381x5=46108
Now Find out all the equations.
9000x5= 45000
300x5=1500
8-5=3
1*5=5
Now Add it all up.
45000+1500=46100
46100+3=46103
46103+5=46108
So, Your Answer is (C)
Your Welcome.
What worksheet or are you talking to somebody else
Answer:
Step-by-step explanation:
1) Let the random time variable, X = 45min; mean, ∪ = 30min; standard deviation, α = 15min
By comparing P(0 ≤ Z ≤ 30)
P(Z ≤ X - ∪/α) = P(Z ≤ 45 - 30/15) = P( Z ≤ 1)
Using Table
P(0 ≤ Z ≤ 1) = 0.3413
P(Z > 1) = (0.5 - 0.3413) = 0.1537
∴ P(Z > 45) = 0.1537
2) By compering (0 ≤ Z ≤ 15) ( that is 4:15pm)
P(Z ≤ 15 - 30/15) = P(Z ≤ -1)
Using Table
P(-1 ≤ Z ≤ 0) = 0.3413
P(Z < 1) = (0.5 - 0.3413) = 0.1587
∴ P(Z < 15) = 0.1587
3) By comparing P(0 ≤ Z ≤ 60) (that is for 5:00pm)
P(Z ≤ 60 - 30/15) = P(Z ≤ 2)
Using Table
P(0 ≤ Z ≤ 1) = 0.4772
P(Z > 1) = (0.5 - 0.4772) = 0.0228
∴ P(Z > 60) = 0.0228
