Answer:
1. D
2. H
3. D
Step-by-step explanation:
1. It is y=mx+b m is slope and b is Y intercept
2. You make it to be in y=mx+b you find the slope and you find where Y is
3. An easy but tedius way is to go to all and plug in the numbers (x,y) or you can first find the slope with the slope formula

Answer:
Step-by-step explanation:
Null hypothesis: u <= 3 minutes
Alternative hypothesis: u > 3minutes
Using a z test formula, z score is
z = (x - u) / (s/√n)
Where x = 3.1, u = 3, s = 0.5, n = 100
z = (3.1 - 3) / (0.5/√100)
z = (0.1) / (0.5/10)
z = 0.1/0.05
z = 2
To calculate for the p value assuming a 0.05 level of significance, the p value is 0.02275 which is less than 0.05. Thus we will reject the null and conclude that there is enough statistics evidence to show that the mean waiting time of all customers is significantly more than 3 minutes.
Answer:
h/3 + p/3 + 8 = k
Step-by-step explanation:
h+p=3(k-8)
h+p=3k-24
h+p+24=3k
h/3 + p/3 + 8 = k
