Answer:

See the explanation for the answer.

Explanation:

add $12, $15, $14   IF   ID   EX   MEM   WB

lw $15, 100($12)       IF   ID    EX   MEM1   MEM2   WB

sub $13, $15, $12           IF   ID   EX   MEM1   WB

add $12, $15, $13                IF   ID   EX   MEM   WB

sub $13,$15,$12 - dependencies-$15,$12

          hazards-$12-read before write data hazard - can be solved through forwarding

              $15-structural hazard-stalled by 3 clock cycle (if no forwarding)

                      -stalled by 1 clock cycle (if forwarding is present)

add $12,$15,$13 - dependencies $15,13

taurus [48]

Answer:

Here,

Discounting factor = ( 1 + r )⁻ⁿ

n = the year of cash flow

r = discount rate = 12%

Year (n)       Cash flow        Discount factor     Present Value

3                  $11,000              0.71178               $7,830  

5                  $50,000              0.567427            $28,371  

6                  $1,00,000           0.506631            $50,663

Therefore,

The amount he or she should pay for the investment today

gogolik [260]

Answer:

X-bar chart

Explanation:

In industrial statistics, the X-bar chart is a type of Shewhart control chart that is used to monitor the arithmetic means of successive samples of constant size, n. The X-bar chart shows how the mean or average changes over time .For example, one might take a sample of 5 shafts from production every hour, measure the diameter of each, and then plot, for each sample, the average of the five diameter values on the chart.  For the purposes of control limit calculation, the sample means are assumed to be normally distributed, an assumption justified by the Central Limit Theorem.

n your own words define employment-at-will and explain whether or not you agree with this principle. Next, discuss your thoughts
raketka [301]

Answer:

a) Employment-at-will is a form of employer-employee relationship which may be terminated by the employer at any time without due consultation with the employee as long as the reason for the termination is not against the law.

b) Work Place Testing: This refers to all the series of tests that an employer can and may administer to a job applicant in order to ascertain their suitability for the role and ensure that they are a culture fit.

Workplace Testing is a fair hiring practice. There is no use hiring an employee only to discover few months later that they cannot do the job as they asserted on their resume. This can be very detrimental to the business as it can leave the business very vulnerable.

e If a candidate is turned down after testing, it doesn't mean they are not capable of being productive at all. It only means that they don't match the person specification for the current job under consideration.

Cheers!
