Answer: 82
Step-by-step explanation:
The formula to find the sample size is given by :-
, where E = Margin of error.
= Population standard deviation for the prior study.
As per given , we have
gallons.
Margin of error : E= 110 gallons
Critical value for 99% confidence level = z* = 2.576
Then, the required sample size : 
{Rounded to the nearest integer.}
Hence, the minimum sample size = 82
Answer:
A) 10
Step-by-step explanation:
12 Lollipops - 2 = 10 Lollipops
Answer:
$141,557.76
Step-by-step explanation:
Chao bought a boat for 160,000
The value of the boat reduces by 4% every year
Therefore the value of the most at the end of three years can be calculated as follows
= 100%- 4%
= 96%
= 160,000 × 96/100^3
= 160,000 × 0.96^3
= 160,000 × 0.884736
= 141,557.76
Hence the price of the boat after 3 years is 141,557.76
Answer: April is correct.
Step-by-step explanation: According to the methods used in systems of equations, if we are to solve this system by setting up the equations
(3 = -2x + 1), we see that the solution is x = -1. If you substitute this x-value back into the original equation, y = -2x + 1, we get the answer y = 3 and thus, receiving the solution to the system (-1,3). Anthony is wrong because the graph includes an extra line at x = 3, throwing off his answers.
The perimeter is 2√10+√41+√13 units
