Answer:
H0: μ = 7.8
Ha: μ > 7.8
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
For the case above;
Let μ represent the true mean length of long-distance calls after the rate reduction
The null hypothesis is that true mean length of long-distance calls after the rate reduction is the same and equal to 7.8 minutes
H0: μ = 7.8
The alternative hypothesis is that the true mean length of long-distance calls after the rate reduction have increased that is greater than 7.8 minutes
Ha: μ > 7.8
Answer:
the cost of the table is 
the cost of the chair is 
Step-by-step explanation:
Let
x-----> the cost of the table
y----> the cost of the chair
we know that
-----> equation A
-----> equation B
substitute equation B in equation A
Find the value of x
----> 
I'm not sure what you mean by the five step plan, but to get the answer, just think about the clues.
(c = number of cats)
8 fewer dogs than cats can be written: c - 8
since we know how many dogs there are: c - 8 = 12
Now, just solve for the variable: c = 20
Hope I helped :)
