D
Step-by-step explanation:
no explination
Answer: FALSE.
Step-by-step explanation:
Given the following equation provided in the exercise:

You need to solve for the variable "x".
In order to solve for "x" you can folllow the steps shown below:
1. You must apply the Addition property of equality and add 13 to both sides of the equation. Then:

2. Finally you need to apply the Subtraction property of equality and subtract "x" from both sides of the equation. So you get:

Therefore, as you can observe, the given equation has no solutions.
Answer: THE ANSWER IS C
Step-by-step explanation:
Answer:
the sum of deviation of all observations of the data 5, 8, 10, 15, 22 from their mean. =26
Step-by-step explanation:
Mean=sum of observation/ No. of observation
={5+8+ 10+ 15 + 22}/5
=60/5=12
Sum of deviations
= |5- 12| + |8 – 12| + |10- 12| + |15- 12| + |22-12|
= 7+4+2+ 3+ 10
= 26
