Answer:
10.4%
Step-by-step explanation:
The original price = $2.40
Price after drop = $2.15
The drop = $2.40 - $2.15 = $0.25
Percentage decrease =
× 100
i.e Percentage decrease =
× 100 = 10.41666667%
Or 10.4% (Rounded up to nearest tenth of a percent).
The two triangles we can see in the diagram are similar, which means that their measurements are proportional. Line MN on the larger triangle MNP is 71.5ft long, and its corresponding line, MA, on the smaller triangle is 71.5-22= 49.5ft long. This means that the scale factor from the bigger to the smaller triangle is 71.5/49.5=13/9.
If line MP on the bigger rectangle is 97.5ft long, then its corresponding line, MB, must be 97.5÷13/9=67.5 ft long.
Therefore, x=67.5 ft
Answer:
This is strong evidence that more than 2% get damaged
Step-by-step explanation:
The company goal is to keep the proportion of damaged machines below 2%


One day an inspector randomly checks 66 washers and finds that 6 of them have scratches or dents
So, x = 6
n = 66


Formula : 



So, the value of test statistic is 4.114
2) What is the P-value of the test statistic?
So, p value using calculator = .00002
p value < α
So, we accept the alternate hypothesis
So, This is strong evidence that more than 2% get damaged
