Answer:
i think its (0,-2)
Step-by-step explanation:
Answer:
The slope is 2/3
Step-by-step explanation:
The line crosses through the blue grid lines leaving gaps on each. Find two points which cross at an intersection such as (0,30) and (30,50). Find the slope by substituting these points into 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:
B' will be at (0, -3)
Step-by-step explanation:
if A is (5, 1), and A' is (6, -2) that means that the value of x increased by 1 and y decreased by three. Because translations are uniform, you apply this to B, getting (0, -3)
