Answer:
a
Step-by-step explanation:
We have been given a table of quiz scores whose standard deviation is 5.6. We are asked to find the test scores that are within one standard deviation of the mean.
First of all, we will find the mean of the test scores using average formula.




The scores within one standard deviation would be mean plus one SD and mean minus one SD that is:


Therefore, the quiz scores 17.15 and 28.35 are within one standard deviation of the mean.
Here’s a pic of my work, it shows that the numbers 2,7,0 repeat.
Hope this helps!! :)
Answer:
Option C matches the conditions.
Step-by-step explanation:
Tempestt graphs a function that has a maximum located at (-4,2).
Now, we have to select from the given options that will satisfy the given conditions.
Since the graph of the function has a maximum at (-4,2). therefore, we can conclude that if the function is of a parabola then it must open down and the vertex of the parabola will be the maximum point i.e. (-4,2).
So, option C matches the conditions which give 'On a coordinate plane, a parabola opens down. It goes through (-6,-2), has a vertex at (-4, 2), and goes through (-2,-2)'. (Answer)
