The correct answer is: 19.39
Explanation:
Given numbers:
22.10, 13.45, 25.10, 17.20, 19.10
Total numbers = 5

Now to find the average of the given sequence, follow these steps:
Step-1:
Add all the numbers to get the total sum:
22.10 + 13.45 + 25.10 + 17.20 + 19.10 = 96.95
Step-2:
Divide 96.95 by 5 to get the average number:

Hence the correct answer is 19.39.
I believe no, it would have to be x = -6.5
Answer:
Step-by-step explanation:
1). Replace one equation with a multiple of itself.
2x + 7y = 3 ⇔ 4(2x) + 4(7y) = 4(3)
2). Yes, systems are equivalent.
Answer:
Step-by-step explanation:
The distance between two points is
d^2=(y2-y1)^2+(x2-x1)^2
D) points (0,0) and (9,12)
d^2=(9-0)^2+(12-0)^2
d^2=81+144
d^2=225
d=15
E) points (1,2) and (-3,5)
d^2=(-3-1)^2+(5-2)^2
d^2=16+9
d^2=25
d=5
