Answer:
do you have a picture of this
To find the mean (average), we first need to add up all the test scores (14 + 19 + 19 + 20 + 16 + 18 + 15 + 17 + 12 = 150). Then, we need to divide that number (150) by the number of numbers in the data set (9 in this case). So the mean of these test scores is about 16.6666666667.
Answer:
4 cm
Step-by-step explanation:
V=L×W×H
V=1 litre = 1000 cm³
H= V/LW
1000/(12.5×20)=4
height= 4cm
Refer the attached figure for the graphic representation of the given quadratic equation.
<u>Step-by-step explanation:</u>
Given expression:

To find:
The graphic representation of the given quadratic function
For solution, plot the graph to the given quadratic equation.
The standard form of the equation is

When comparing with given quadratic equation,
a = 1, b = - 8, c = 24
Axis of symmetry is 
By applying the values, the axis of symmetry of given equation is

The vertex form of quadratic equation is 
Where, (h,k) are the vertex.
Convert the quadratic equation into vertex form.
By completing the square,



On comparison,
(h , k) = (4 , 8)
Now, plot the equation with vertex (4,8) [refer attached figure].
The rate of realtionship a would be 2/4 because when you do the point slope formula, you get the slope of 2/4 so 0.6 ends up being 6/10 which is greater than 1/2 (1/2=2/4). 2/3 is greater than 1/2 and 3/4 is greater than 1/2 so it should be all of them except 1/4. Just find at the slope and see what greater than that slope!
