Answer:
Therefore,
x = -13 , y = 17 or x = 12 , y = 42
Step-by-step explanation:
First, you have to form equation in terms of x and y. With the given informations, the equations will be :
Next, you have to solve it by substitution :
Answer:
True

APEX
Answer:
Step-by-step explanation:
Given
Required
The sample mean and the sample variance
First, calculate the midpoints
And so on...
So, the table becomes:
So, the sample mean is:
The sample variance is:
The number of ways can arrange the songs on the CD will be 3,628,800.
<h3>What are permutation and combination?</h3>
A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.
Suppose Allen is going to burn a compact disk (CD) that will contain 10 songs.
Then the number of ways can arrange the songs on the CD will be given by 10 factorial.
⇒ 10!
⇒ 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
⇒ 3,628,800
Thus, the number of ways can arrange the songs on the CD will be 3,628,800.
