avg. service time = 2hrs +/- 32 mins = 180 mins +/- 32 mins = 148 mins or 212 mins.
Random sample = 64/400 = 16 % of the total population.
Seriously I dont know the answer to the problem, but it is an interesting question, and it forces me to study probability more.
Since one piece is four time the length <em>x, </em>we can represent that as 4x.
Thus making the equation:
4x+x=275
5x=275
x=55
4(55)=220
220+55=275
So, the length of the longer piece is 220 inches, and the length of the shorter piece is 55 inches.
Answer:
1:7
Step-by-step explanation:
125:875
Then simply
The GCF between the two is 125:
125/125 = 1
875/125 = 7
So, the answer is 1:7!
Answer:
7 will be your correct answer
