Answer:
Independent = time intervals
Dependant = how far the leaves travel
Step-by-step explanation:
independent = what you change
dependent = what you measure

answer : x = 1
The graph of two functions are attached below
First function is f(x) = -2x+3
Second function g(x)=
We graph both the functions and find out the point where both graphs intersects
From the attached graph , we can see that both graph intersects at x= 1.08
So the solution for f(x)= g(x) is x=1
Answer:
b. We do not have enough information to make a conclusion.
Step-by-step explanation:
For testing difference of means our null hypothesis and alternative hypothesis is
H0: There is no significant difference between the average packing time of old machine and new machine i.e. μold-μnew=0.
Ha:There is significant difference between the average packing time of old machine and new machine i.e. μold-μnew≠0.
When the confidence contains the null values then there is no significant difference exists. Here the specified null value is 0. A 95% confidence interval (-6.85, 0.34) shows that it contains null value so, there is no significant difference between the average packing time of the two machines at 5% level of significance. This results is for 95% confidence interval. For 90% confidence interval result may vary and we don't have sufficient information given to compute 90% confidence interval.
