Answer:
Step-by-step explanation:
This quadratic is of the form
where h and k are the coordinates of the vertex. Notice that inside the parenthesis it very specifically follows the format (<u>x -</u> h)². That means that if you have something like what we have here, ( x + 3)^2, it was originally (x - (-3))^2, and the value for h is -3. k is much simpler to determine. Our 2 at the end is a +2, so the k is 2. The vertex then is (-3, 2).
Answer:
Mean = 58.25
Median = 57.5
Mode = 49
Step-by-step explanation:
We are given the following data set:
55, 51, 74, 61, 67, 60, 49, 49
Formula:
Sorted data:
49, 49, 51, 55, 60, 61, 67, 74
Mode is the entry with highest frequency.
49 appeared two times.
Mode = 49
Formula:
All these are less than 60 seconds, which indicates that students perceive 1 minute to pass sooner than it actually has.
