Answer: It is not enough evidence to support the researcher's claim.
Step-by-step explanation:
Since we have given that
n = 500
So, the hypothesis are as follows:
So, the z value would be
At α = 0.05
z= -1.64
So, 1.64<-1.33
So, we accept the null hypothesis.
Hence, it is not enough evidence to support the researcher's claim.
Answer:
-6
Step-by-step explanation:
By looking at the graph, you can see that the graph intersects the x-axis at (-6,0), that is the zero of g.
Answer:
x^2+15x+54
Step-by-step explanation:
x^2+15x+54
is the answer :)
Let's define the following variable:
t = total time it takes to assemble a shelving unit together.
We then have the following equation:
1/5 + 1/3 = 1 / t
Solving the equation we have:
3t + 5t = 15
8t = 15
t = 1,875 hours
Answer:
the time it takes for worker A and worker B to assemble a shelving unit together is:
t = 1,875 hours
