The jump from 59 mph to 72 mph is (72-59) mph, or 13 mph.

13 mph
---------- * 100% = 22.0% is the percentage increase in her speed.
59 mph

Ivenika [448]

Answer:

The quick ratio is 4.75:1.

Step-by-step explanation:

From the given information it is clear that:

Cash = $340,000

Inventory = $280,000

Accounts receivable =  $40,000

Accounts payable = $65000

Other current liabilities = $15000

Formula for quick ratio:

\text{Quick ratio}=\frac{\text{Cash + Current receivables + short-term investment}}{\text{Current Liabilities}}

Substitute Cash = 340000, Current receivables=40000, Current Liabilities= (65000+15000).

\text{Quick ratio}=\frac{340000+40000}{65000+15000}

\text{Quick ratio}=4.75

Therefore the quick ratio is 4.75:1.

k0ka [10]

Answer: b. 0.8413

Step-by-step explanation:

Given : The average time taken to complete an exam, X, follows a normal probability distribution with \mu=60\text{ minutes} and \sigma=30\text{ minutes} .

Then, the  probability that a randomly chosen student will take more than 30 minutes to complete the exam will be :-

P(x>30)=P(z>\dfrac{30-60}{30})\ \ [\because\ z=\dfrac{x-\mu}{\sigma} ]\\\\=P(z>-1)=P(z-z)=P(Z

 [using z-value table]

Hence, the probability that a randomly chosen student will take more than 30 minutes to complete the exam =  0.8413

Which of the following is a correct way to measure productivity? a. Divide the number of hours worked by the quantity of output.
11111nata11111 [884]

Answer:

b. Divide the quantity of output by the number of hours worked.

Step-by-step explanation:

<em>Since the ratio of the number of output to the number of hours worked shows the productivity. </em>

Thus, option (b) is correct.

Productivity is used to converting inputs into useful output. It measures the efficiency of a person, system, machine, factory, etc.

For Example: The employee who works less hours and assembled more radios has more productivity, that employee knows how to utilize time.
