Answer:
at most
Step-by-step explanation:
The sample drawn from the population is a relative representation not the absolute representation. The box has 100 tickets in it and sample of tickets is selected to identify difference between sample sum and 252. The at most value for the sample sum can be 278.32 and value cannot exceed beyond this.

Answer:
The correct answer is (a).
Step-by-step explanation:
Nickels are 5-cents coins
Quarters are 25-cents coins
1 dollar = 100 cents
N represents the number of nickels and;
Q represents the number of quarters.
The system of simultaneous equations is:
N + Q = 35 ... (i)
N + 
Q = $5.15 ... (ii)
Simplifying further by multiplying (ii) with 100 throughout gives:
N + Q = 35 ... (i)
5N + 25Q = $515 ... (ii)
You can rearrange it to:
N = 35 - Q ... (i)
5N + 25Q = $515 ... (ii)
So (a) is the correct answer.
The unknown quantities are:
A = The number of adult tickets sold
C = The number of child tickets sold
Your equations could be:
8A + 5C = 550
C - 10 = A

According to Avogadro's law, 1 mole ,i.e., 6.2 * 10^23 particles of
every substance have mass equal to its molecular mass in grams. Since
the molecular mass of CuSO4 is 80 grams. It means 6.2 * 10^23 particles
of CuSO4 have a mass of 80 grams. Now u can calculate the mass of 3.36 *
10^23 particles by unitary method 3.36 * 10^23 *80/6.23 * 10^23 grams </span>
