Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Write out equation
2(3 - x) = 16(x + 1)
Step 2: Distribute
6 - 2x = 16x + 16
Step 3: Add 2x on both sides
6 = 18x + 16
Step 4: Subtract 16 on both sides
-10 = 18x
Step 5: Divide both sides by 18
-10/18 = x
Step 6: Simplify
-5/9 = x
Step 7: Rewrite
x = -5/9
The answer to the question is 2 because when you add all the numbers and divide it by the amount of numbers (including 0) you get the answer of 2

Answer:
No, the weight loss program doesn't have statistical significance.
Step-by-step explanation:
We are given that in a study of a weight loss program, 7 subjects lost an average of 41 lbs.
It is found that there is about a 40% chance of getting such results with a diet that has no effect.
Firstly, statistical significance means that the event is sure to be happen and there is a proper statistical calculation behind it.
But here it is stated that there is a 40% chance of getting such results with a diet that has no effect which means that the event is unlikely to happen by chance and it is just a prediction so, the weight loss program is not statistically significant.
Now, practically significant means that there is a large difference in the subjects being tested.
Here, the weight loss program is considered to be practically significant because there is a large amount of weight loss of 43 lbs of the subjects which is a large amount.
