Step-by-step explanation:
11 and 12
Answer:
-1, 0 and 1
Step-by-step explanation:
Let's work through this step by step.
x goes from -2 to 2 so we will check each integer in between.
f(-2) and g(-2) is the first one. The table shows f(-2)=-8 and g(-2)=-2, so f(-2) does not equal g(-2)
Now we just keep doing this for x=-1,0,1, and 2
f(-1) = -1 and g(-1) = -1 so f(-1)=g(-1)
f(0)=0 and g(0)=0 so f(0)=g(0)
f(1)=1 and g(1)=1 so f(1)=g(1)
f(2)=8 and g(2)=2 so f(2) does not equal g(2)
So there were three xs that made f(x) = g(x). -1, 0 and 1, so those are your answers.
Answer:
48.5
Step-by-step explanation:
The constant of proportionality in this case is the speed at which Andrew travels.
We know that the speed is equal to:
v = d / t
We know the distance that is 145.5 miles and the time is 3 hours, replacing:
v = 145.5 / 3
v = 48.5 mi / h
which means that the equation would be:
y = k * x
where k, that is, the constant of proportionality is the velocity 48.5.
y = 48.5 * x
To check if for example x is worth 3, it would be:
y = 48.5 * 3
y = 145.5
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
