<h2>Answer : Option A) 1 foot/second</h2><h3>Explanation :</h3>
If we consider that the plates are placed 2 ft apart and there has to be 1800 meals that needs to be delivered in an hour.
so if we multiply 2 ft and 1800 meals that is delivered in 1 hour,we get 2 X 1800 = 3600 meals in an hour.
If we try to accommodate the plates at each ft then there will be 3600 meals delivered in 1 hour.
we know that 1 hour has 3600 seconds in it.
So, here the distance is 1 ft, and speed has to be determined time is 1 hour = 3600 seconds
3600 meals / 3600 seconds = 1 foot per second.
OR 1800 meals set at 2 ft apart in 3600 seconds will give the speed of the belt as 1 foot per second.
(1 ft = speed X 1 hour)
<h2>so, the speed also will be 1 foot per second. </h2>
Answer:
The portfolio SD is A. 20.65%
Explanation:
The standard deviation tells the total risk (both systematic and unsystematic) associated with a stock or a portfolio. The portfolio risk or the standard deviation of portfolio can be calculated using the following formula as attached in the picture below.
Using this formula, the standard deviation of the portfolio is:
SDp = √(0.3)² * (0.2)² + (0.7)² * (0.25)² + 2 * (0.3)*(0.7) * 0.4 * (0.2)*(0.25)
Portfolio SD = 0.20645 or 20.645% rounded off to 20.65%

Explanation:
Six Sigma is a quality business management strategy which helps business organizations to improve the quality of processes, products and services by discovering and eliminating defects, variations or errors. It is a strategic business concept that was developed in 1986 by Motorola.
This ultimately implies that, the six sigma approach to quality control detects potential problems early to prevent their occurrence.
Under the six sigma approach, any process that doesn't provide customer satisfaction or causes challenges in an organisation's process should be eliminated from the system in order to produce quality products and services. It allows only 3.4 defective features for every million opportunities and as such expects processes to be defect free 99.99966 percent of the time.
<em>Generally, there are two (2) main methods of achieving the six sigma approach;</em>
<em>1. DMAIC: define, measure, analyze, improve and control.</em>
<em>2. DMADV: define, measure, analyze, design and verify. </em>
