Answer:
is there suposed to be a picture? also if thats measurements then yes.
Step-by-step explanation:
A. 168 feet
b. 1 yard = 3 feet
168*3=504 so, 168 feet =504 yards
c. 504 yards*$15=7560
d. $7560
The mean price goes between $ 41.16 and $ 42.84, so a value of $ 48 is unusually high.
Since the average price of an item is $ 42 with a standard deviation of $ 3, to find a 98% confidence interval about the mean, and determine if a value of X = 48 is unusually high or if it is normal, the following calculations should be done:
- (((42 - 3) + (42 + 3)) / 2) x 0.98 = X
- ((39 + 45) / 2) x 0.98 = X
- 42 x 0.98 = X
- 41.16 = X
- (((42 - 3) + (42 + 3)) / 2) x 1.02 = X
- ((39 + 45) / 2) x 1.02 = X
- 42 x 1.02 = X
- 42.84 = X
Therefore, as the mean price goes between $ 41.16 and $ 42.84, a value of $ 48 is unusually high.

Answer:
I think it is supplementary
x-(x/3)=2
turn x into a fraction x/1
to get x/1 -x/3 = 2
multiply x/1 x 3/3 to get both fractions with same denominator
3x/3 - x/3
(3x-x)/3
3x-x = 2x
so now you have (2x)/3 =2
multiply both sides by 3 to get 2x = 6
divide bothe sides by 2 to get x = 3, which is the answer
