Answer:
<u>78.5 (78.477)</u>
Step-by-step explanation:
5% of 74.74 is 3.737
74.74+3.737 = 78.477
Domain refers to all of the x-values that satisfy the line, and the range refers to all of the y-values that satisfy the line.
Since t corresponds to the x-ordinates, then the domain becomes:
0 ≤ t ≤ 6
and the range becomes:
0 ≤ v ≤ 150
In short, the answer is (A)
it is two i think. hope i could help
Answer:
E. .10
Step-by-step explanation:
The standard deviation of sampling distribution of sample mean=σxbar=?
σxbar=σ/√n where, σ is the population standard deviation and n is sample size
We are given the population variance σ²=0.03 and we can calculate the population standard deviation from it by taking square root of variance
σ=√σ²
σ=√0.03
σ=0.1732
The standard deviation of sampling distribution of sample mean=σxbar=σ/√n
We are selecting 3 bolts so, n=3
σxbar=0.1732/√3
σxbar=0.1732/1.732
σxbar=0.1
So, The standard deviation of sampling distribution of sample mean is 0.1.
