Answer:
The domain of g(x) is -3 to infinity
Step-by-step explanation:
Given

Required
Determine the domain of g(x)
We start by expressing the content of the square root in the following form:

Subtract 3 from both sides



This can be expressed using interval notation as follows:

<em>Hence, the domain of g(x) is -3 to infinity</em>
True mean = mean+/- Z*(SD/sqrt (n))
Where
Z = 1.96 at 95% confidence interval
Mean = 10.3 pounds
SD = standard deviation = 2.4 pounds
n= sample size = 37 packages
Substituting;
True mean range = 10.3+/- 1.96 * 2.4/Sqrt (37) =10.3+/- 0.77 = 9.53<mean<11.07
Answer:
total distance= 12000+12000=24000
total time = 5+6=11
average speed of plane= 24000/11
