Answer:
$2.59
Step-by-step explanation:
Let b and m represent the costs of a banana split and a milkshake, respectively. Then the two purchases are ...
b +5m = 16.24
3b +2m = 15.05
Subtracting the second equation from 3 times the first, we have ...
3(b +5m) -(3b +2m) = 3(16.24) -(15.05)
13m = 33.67 . . . . . . simplify
m = 2.59 . . . . . . . . . divide by 13
The cost of a milkshake is $2.59.

Answer:
0.427
Step-by-step explanation:
Standard error for the sampling distribution refers to the standard deviation of the samples taken from a population. The standard error equals the standard deviation divided by the square root of the sample size
The probability of customers who drink tea (p) = 24% = 0.24, the sample size of customers (n) = 300.
Standard error = 
where σ is the standard deviation.
Standard error = 
Answer:
9 gallons per minute
Step-by-step explanation:
If there are 54 gallons that came out of a pipe within 6 minutes, then we divide 54 by 6 to get how many would come out in 1 minute.
54/6 = 9.
