Answer:
x = 8.0
Step-by-step explanation:
Since the triangle is right use the cosine ratio to solve for x
cos37° =
= 
Cross- multiply
x = 10 × cos37° ≈ 8.0 ( to the nearest tenth )
If you follow the money, there was quite a bit to made if a shorter passage was found to China. The trips around the Horn and around South America were difficult and many ships were lost
The tax on the pillow is 0.08($8) and is $0.64.

Answer:
The sample size needed to be taken is approximately 74.
Step-by-step explanation:
To get alpha; we have 1 - 0.95 = 0.05
Therefore, 
The we look up z* in a Standard Normal table where α = 0.025 area in each tail.
From the table, z* = 1.96
From the question variance is 484, then the standard deviation is 22
Standard deviation = 
And margin of error is 5 or less
The formula for margin of error is given as:
margin of error = 

The approximate value of n is 74.
