Answer:
Step-by-step explanation:
Given that the owner of the local eat-in pizza restaurant wants to investigate the possibility of starting to deliver pizzas.
Sample size = n =45: Sample mean= x bar = 31.4 and s = 4.5
Std error of sample =
(One tailed test at 5% )
Mean difference = 1.4
Test statistic = Mean diff/se = 2.087
(t test only can be used as population std dev not known)
p value = 0.0218
Since p <0.05 our alpha, we reject null hypothesis.
There is a strong evidence that on average it takes more than 30 minutes for home delivery

Answer:
See below.
Step-by-step explanation:
First, we can see that .
Thus, for the question, we can just plug -1 in:
Saying undefined (or unbounded) will be correct.
However, note that as x approaches 2, the values of y decrease in order to get to -1. In other words, will always be greater or equal to -1 (you can also see this from the graph). This means that as x approaches 2, f(x) will approach -.99 then -.999 then -.9999 until it reaches -1 and then go back up. What is important is that because of this, we can determine that:
This is because for the denominator, the +1 will always be greater than the f(x). This makes this increase towards positive infinity. Note that limits want the values of the function as it approaches it, not at it.
