<u>Software Development and Client Needs</u>

In Incremental method of software development customers who do not have a basic idea of the development process are being carried along on like other methods that will relegate them to the background until a product is ready.

With this model and structure in place, when softwares/ products are built from several stages e.g prototype, testing, and when new features are added customers are always carried along with their valuable feedback and suggested greatly considered to achieve the customers satisfactions

This model will work well for the customers/clients who does not have a clear idea on the systems needed for their operations.

In summary the incremental model combines features from the waterfall and prototyping model.

Write a SELECT statement that returns one row for each customer that has orders with these columns: The email_address column fro
Dafna11 [192]

Answer:

The statement is as follows:

Explanation:

We had better avoid such correlated subqueries by instead using aggregation with GROUP BY:

SELECT

   c.email_address,

   COUNT(DISTINCT o.order_id) AS num_orders,

   COALESCE(SUM(oi.quantity * (oi.item_price - oi.discount_amount)), 0) AS total_amount

FROM customers c

LEFT JOIN orders o

   ON c.customer_id = o.customer_id

INNER JOIN order_items oi

   ON o.order_id = oi.order_id

GROUP BY

   c.customer_id,

   c.email_address;

The inside temperature of a wall in a dwelling is 15°C. If the air in the room is at 21°C, what is the maximum relative humidity
Sveta_85 [38]

Given:

Wall's inside temperature, T_{wa} = 15^{\circ}C

Room air temperature,  T_{air} = 21^{\circ}C

Solution:

To calculate percentage max relative humidity, we make use of steam table for saturated pressure of wall and air:

From steam table:

At T_{wa} = 15^{\circ}C:

P_{wa(sat)} = 1.7057 kPa

At  T_{air} = 21^{\circ}C:

P_{air(sat)} = 2.487 kPa

Now,

% Relative Humidity (RH)_{max} = \frac{P_{wa(sat)}}{P_{air(sat)}} \times 100

(RH)_{max} = \frac{1.7057}{2.487}\times 100

(RH)_{max} = 68.58%

Therefore, max Relative Humidity of the air before the occurrence of condensation in wall is 68.85%

Steel bar A of 5 mm diameter is subject to a stress of 500 MPa. Aluminum bar B of 10 mm diameter is subject to a stress of 150 M
weqwewe [10]

Answer:

aluminum bar carrying a higher load than steel bar

Explanation:

Given data;

steel abr

diameter = 5 mm

stress = 500 MPa

aluminium bar

diameter = 10 mm

stress = 150 MPa

we know

stress = laod/area

for steel bar

500 = \frac{P}{\frac{\pi}{4} 5^2}

solving for P

P = 9817.47 N

for Aluminium bar

150 = \frac{P}{\frac{\pi}{4} 10^2}

solving for P

P = 11790 N

aluminum bar carrying a higher load than steel bar
