Because it has ">" in it.
Answer:
4.7 · 10^7
Step-by-step explanation:
Answer:
largest number os students = 73
smallest number of students is 16
Step-by-step explanation:
Distribution of student over the period of 13 year is given in the following table
first column represent the stem which are on tens digit while column 2 represent the leaf which are on one digit.
1 6 9
2 4 4 9
3 3 4 7
4 0 2 6 9
5
6
7 3
8
9
hence the graduate student number is calculated as
16, 19, 24,24,29, 33, 34,37,40,42,46,49,73.
hence from the obtained data largest and smallest number of students over a period of 13 year can be calculate
largest number os students = 73
smallest number of students is 16
Answer: The range is y ≥ 3.
Step-by-step explanation:
When we have an equation:
y = f(x)
The range is the set of the possible values of y.
In this case, we have:
y = f(x) = 2*x^2 - 20*x + 53
This is a quadratic equation, and the leading coefficient is positive. This means that the arms of the graph will open upwards.
Then the minimum value of y will be the vale at the vertex.
We know that for a quadratic equation of the form:
a*x^2 + b*x + c
The vertex is at:
x = -b/2a
Then in this case, the vertex will be at:
x = -(-20)/(2*2) = 20/4 = 5
Then the smallest value of this function will be:
f(5) = 2*5^2 - 20*5 + 53 = 3
This is the smallest value that y can take, and y can take any value greater than 3.
Then the range can be written as:
y ≥ 3.
