Answer:
x=1+2/15
Step-by-step explanation:
4(5x-3)=5x+5=118
We move all terms to the left:
4(5x-3)-(5x+5)=0
We multiply parentheses
20x-(5x+5)-12=0
We get rid of parentheses
20x-5x-5-12=0
We add all the numbers together, and all the variables
15x-17=0
We move all terms containing x to the left, all other terms to the right
15x=17
x=17/15
x=1+2/15
Answer: (0.132132, 0.274368)
Step-by-step explanation:
Given : A simple random sample of 123 people living in Gastown and finds that 25 have an annual income that is below the poverty line.
i.e. n= 123

Critical value for 95% confidence interval : 
Confidence interval for population :

i.e. 

Hence, the 95% confidence interval for the true proportion of Gastown residents living below the poverty line : (0.132132, 0.274368)
Answer:
17mL
Step-by-step explanation:
Convert 0.85 gr to miligrams
If 100 mg is 1 gr. Then, 0.85 gr is 850 mg
So, 850 multiply for 5ml and divide for 250 ml
or 
So all mg is gone and the amount of mililiters is 17
