Answer:
2.66216x10^20
Step-by-step explanation:
Answer:
xbar=14.3421
s=18.7920
Step-by-step explanation:
sample mean
xbar = ∑x/n = (0.20 + 0.73 + 0.99 +1.29 + 2.84 + 3.34 + 4.07 + 4.69 + 4.86 + 6.53 + 7.45 + 8.07 + 8.21 + 12.39 + 31.67 + 32.53 + 33.92 + 36.00 +72.72)/19=14.3421
where n stands for the size of the sample
sample deviation
s= 
(∑
/(n-1)) = (∑
- 
)/(n-1)) = (0.20^2 + 0.73^2 + 0.99^2 +1.29^2 + 2.84^2 + 3.34^2 + 4.07^2 + 4.69^2 + 4.86^2 + 6.53^2 + 7.45^2 + 8.07^2 + 8.21^2 + 12.39^2 + 31.67 ^2+ 32.53^2 + 33.92^2 + 36.00^2 +72.72^2-19*14.3421^2)/(19-1)) = 18.7920
Answer:
a) 1/7 liters of petrol is used for each mile
Step-by-step explanation:
Justin fills his car with 40 litres of petrol. After travelling 35 miles it's down to 35 litres.
From the above statement:.
The difference is :
40 litres - 35 liters = 5 liters
Hence:
After travelling 35 miles he used 5 liters
(a) How much petrol does the car use each mile?
This is calculated as:
35 miles = 5 Liters
1 mile = x liters
Cross Multiply
35x = 5 Liters
x = 5/35
x = 1/7 liters
Hence, for each mile, 1/7 liters of petrol is used
