Answer:
(d) f(x) = 2x^2 - 16x + 35
Step-by-step explanation:
The x-coordinate of the extreme will be found at ...
x = -b/(2a)
where the function is f(x) = ax²+bx+c.
The extreme will be a minimum when a > 0. (eliminates choices A and B)
The x-coordinates of the extremes are ...
C: -(-4)/(2(4)) = 1/2
D: -(-16)/(2(2)) = 4 . . . . . matches the requirement
The appropriate choice is ...
f(x) = 2x^2 - 16x + 35
Answer:
The mean number of the children is 1.2
<em></em>
Step-by-step explanation:
Given
Children: 0, 1, 2, 1, 2
Required
Determine the Mean number
The mean of a set is calculated as follows;

Where x is the given set and n is the number of sets
In this case, n = 5 children
Hence;



<em>Hence, the mean number of the children is 1.2</em>
Answer:
Percentage of total I have = 80%
Step-by-step explanation:
Given:
Price of Box = $60
I Have = $48
To Find:
Percentage I have = ?
Solution:
In this question we are just supposed to find out the percentage of the Value we have so
Percentage can be found by the formula
Percentage
%
Now we have the values of all
So putting in the values
Percentage
%
%
= 80%
So the Percentage of total cost I have is 80%
Percentage of total = 80%
