Answer:
0.6666 or
Step-by-step explanation:
Since this is a ratio problem we can simply use the rule of three to solve it. We need to multiply the diagonal values and divide by the remaining value to get the variable which in this case is x (how much life he has already lost)
15 minutes <=======> 1 life
10 minutes <=======> x
(10 * 1) / 15 = x
10 / 15 = x
0.6666 or = x
Finally, we can see that Farid has lost 0.6666 or in those 10 minutes
Answer:
d
Step-by-step explanation:
let the number be n then one third of the number is
n and 2 more than this is
2 + n = 8 ( is 8 means = 8 ) → d
Answer:
The mean of T is 10 seconds
Step-by-step explanation:
The given parameters are;
The mean completion time of each step, μ = 10 seconds
The standard deviation, σ = 5 seconds
Each step is independent from the other steps
The variable that represents the total completion time for the three steps = T
We have the mean of T, , given by the combined mean as follows;
Where;
n₁ = n₂ = n₃ = 1, each step is taken only once, we have;
Therefore, the mean of T = 10 seconds
