Answer:

The answer is (b) 47.77 inches

Explanation:

The first quartile is the 25th percentile, which is where 25% of the data falls. Since the data is normally distributed, we will use the formula

z = \frac{height - mean}{sd}

First step is to look up the z-value of 25% = 0.25 in the standard normal table. z-value of 0.25 ≈ -0.67.

Therefore, the height that represent the first quartile is given as height = z*sd + mean = (-0.67) (3.15) + 49.9 = 47.77.

Greeley [361]

Fed can achieve its goals using the given tools as shown below.

<h3>What is money supply?</h3>
  • The money supply (or money stock) in macroeconomics refers to the entire volume of currency held by the public at a given point in time.
  • There are numerous definitions of "money," but common measures often include currency in circulation and demand deposits (depositors' easily accessible assets on financial institutions' accounts).
  • A country's central bank may utilize a definition of what constitutes legal money for its own reasons.
  • Money supply data is recorded and released, typically by a government agency or the country's central bank.
  • Changes in the money supply are monitored by public and private sector experts because it is believed that such changes affect the prices of securities, inflation, exchange rates, and the business cycle.

In the given situation, Fed can achieve its goals using the given tools:

  1. Change the reserve requirement - The Fed should lower the reserve requirement to 48 ± 1 percent.
  2. Change the discount rate - The Fed should lower the rate by 12.50 ± 0.01 percentage points.
  3. Use open market operations - The Fed should buy $125.00 ± 0.01 worth of bonds.

Therefore, Fed can achieve its goals using the given tools as shown.

Explanation:

Giving the following information:

Units sold= 500

Purchases:

Dec. 1= 300 units at $250

<u>To calculate the cost of goods sold under the FIFO (first-in, first-out) method, we need to use the cost of the firsts units incorporated into inventory:</u>

COGS= 300*250 + 200*275

COGS= $130,000

<u>Now, the ending inventory:</u>

Ending inventory= 400*275= $110,000
