Answer:
Step-by-step explanation:
Given
Three and one-half yards of fabric i.e. 
yards
and five and one-half yards of fabric is 
yards
Difference between five and one-half yards and Three and one-half yards is
=2 yards which is positive
Thus it clear that 
Answer:
m = -10.7
Step-by-step explanation:
m + 4.1 = -6.6
Subtract 4.1 from both sides:
m + 4.1 = -6.6
- 4.1 - 4.1
m = -10.7
Final answer: m = -10.7

Answer:
20%
Step-by-step explanation:
Given that
The car is depreciated at a rate of 7% per year
We need to find out the percentage when the car is depreciated after 6 years
So,
Since the car is depreciated by 7% so we can say it can be 0.93 times in a year
Now after 6 years, it would make
= 0.93^3
= 0.80
So, the percentage is
= 1 - 0.80
= 0.20
= 20%
True mean = mean+/- Z*(SD/sqrt (n))
Where
Z = 1.96 at 95% confidence interval
Mean = 10.3 pounds
SD = standard deviation = 2.4 pounds
n= sample size = 37 packages
Substituting;
True mean range = 10.3+/- 1.96 * 2.4/Sqrt (37) =10.3+/- 0.77 = 9.53<mean<11.07
