Question B.)
1.5w + 3 -3 = 3 + 2w -3
1.5w = 2w
If you plug in 0 into w...
1.5 * 0 = 2 * 0
Therefore w = 0
Question C.) 48 + 8x + 23 = 7
71 + 8x = 7
71 + 8x -71 = 7 - 71
8x = -64
x = -64 / 8
x = -8
Question d.)
6x - 21 = 5x + 17 + x
6x - 21 - 6x = 5x + 17 + x - 6x
-21 = 17
IMPOSSIBLE so x = ns
I believe it’s D. hope this helps!! (please mark as brainliest). ❤️❤️

Step-by-step explanation:
<span>Ans : a)
What is the standard deviation of this sampling distribution?
Ď /âšn
= 60/âš840
=2.0702
b)
1 standard deviation of the mean
= (1) 2.07
= 2.07
c)
272+/- 1(2.07)
(269.93, 274.07)</span>
Total number of seats = 5
Total number of friends = 5
We want to find in how many ways the 5 friends can sit or be arranged in 5 seats. This can be found using permutations.So we are to find the permutations of 5 objects taken 5 at a time. This can be expressed as 5P5.
5P5 = 120
So, the 5 friends can sit in 120 different ways.
The correct answer is option D
