Answer:
The size of the bank's actual reserves is $44000.
Step-by-step explanation:
The bank has checkable deposits of $150,000 and it has excess reserves of $14,000.
Therefore, the required reserves = 20% of the checkable deposit
= dollars. {As the reserve ratio is 20%}
Now, we know that the bank's actual reserves = The required reserves + The excess reserves
= $(30000 + 14000)
= $44000
Therefore, the size of the bank's actual reserves is $44000. (Answer)
Answer:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
The margin of error is of:
In a clinical test with 2161 subjects, 1214 showed improvement from the treatment.
This means that
95% confidence level
So , z is the value of Z that has a p-value of , so .
Margin of error:
The margin of error for the 95% confidence interval used to estimate the population proportion is of 0.0209.
Answer:
20:50
Step-by-step explanation:
2:5
They got 20 by multiplying 2 by 10 so we multiply 5 by 10 which is 50
Answer:
Line C is the correct answer
Step-by-step explanation:
A: y = (-20/3) * x + 56
B: y = (-10/3) * x + (80/3)
C: y = 2 * x + 8
D: y = (27/7) * x - 7
check: line C -- y = 2 * (-7) + 8 = -6 (-7, -6)
y2 = 2 * 6 + 8 = 20 (6, 20)
y3 = 2 * 2 + 8 = 12 (2, 12) .... correct
