Answer:
The answer is 30
Step-by-step explanation:
both of the square roots cancel out
"Mean" is another way of saying average.
To find the average/mean, add up all the numbers and then divide by the amount of numbers that are in the data set.
Step 1: Add the numbers.
0 + 1 + 1 + 2 + 5 + 6
= 15
Step 2: Divide the sum by the amount of numbers in the set.
There are 6 numbers in the data set.
Their sum is 15.
Divide 15 by 6.
15 / 6
= 2.5
Answer:
The mean, also known as average, of this data set is 2.5.
Hope this helps!
Answer:
Step-by-step explanation:
There are many methods to find the vertex of a quadratic function. The method that I will show you is by using the roots of the function
In the case of this function, the roots are ..
The vertex of a function will always be directly between these roots. The number that is directly between -1 and -3 is -2. This means that the x-value of our vertex is -2.
Now that we have the x-value, we can plug this into the function in order to get our y-value.
We have found that our y-value is -2. This means that the coordinates of the vertex are
