What is the output of the sum of 1001011 and 100011 displayed in hexadecimal?
Answer:
[tex]1001011_2[/tex] [tex]+[/tex] [tex]100011_2[/tex] [tex]=[/tex] [tex]6E_{hex}[/tex]
Explanation:
Required
[tex]1001011_2 + 100011_2 = []_{16}[/tex]
First, carry out the addition in binary
[tex]1001011_2[/tex] [tex]+[/tex] [tex]100011_2[/tex] [tex]=[/tex] [tex]1101110_2[/tex]
The step is as follows (start adding from right to left):
[tex]1 + 1 = 10[/tex] --- Write 0 carry 1
[tex]1 + 1 + 1(carry) = 11[/tex] ---- Write 1 carry 1
[tex]0 + 0 + 1(carry) = 1[/tex] ---- Write 1
[tex]1 + 0 = 1[/tex] --- Write 1
[tex]0 + 0 = 0[/tex] ---- Write 0
[tex]0 + 0 = 0[/tex] ---- Write 0
[tex]1 + 1 = 10[/tex] --- Write 0 carry 1
No other number to add ; So, write 1 (the last carry)
So, we have:
[tex]1001011_2[/tex] [tex]+[/tex] [tex]100011_2[/tex] [tex]=[/tex] [tex]1101110_2[/tex]
Next, convert [tex]1101110_2[/tex] to base 10 using product rule
[tex]1101110_2 = 1 * 2^6 +1 * 2^5 + 0 * 2^4 + 1 * 2^3 + 1 * 2^2 + 1 * 2^1 + 0 * 2^0[/tex]
[tex]1101110_2 = 64 +32 + 0 + 8 + 4 + 2 + 0[/tex]
[tex]1101110_2 = 110_{10}[/tex]
Lastly, convert [tex]110_{10}[/tex] to hexadecimal using division and remainder rule
[tex]110/16 \to 6\ R\ 14[/tex]
[tex]6/16 \to 0\ R\ 6[/tex]
Write the remainder from bottom to top;
[tex]110_{10} = 6(14)_{hex}[/tex]
In hexadecimal
[tex]14 \to E[/tex]
So, we have:
[tex]110_{10} = 6E_{hex}[/tex]
Hence:
[tex]1001011_2[/tex] [tex]+[/tex] [tex]100011_2[/tex] [tex]=[/tex] [tex]6E_{hex}[/tex]

In which of the following phases of filmmaking would a production team be focused on the process of casting?
(Select all that apply).
pre-production
post-production
development
distribution
Explanation:
There are five phases of film production and they include development, pre-production, production, post-production and distribution.
Answer:
pre-production
Explanation:
edg2021
Once the film concept has been developed, the film company transitions to the production phases: pre-production, production, and post-production. In pre-production, the technical details are worked out, a schedule is set, and the resources to produce the film are assembled. This includes casting the film, filling the technical positions, and scheduling the production. The actual filming takes place during the production phase, followed by a post-production phase in which the footage is edited and the final film emerges.

For a processor with primary and secondary caches, an instruction cache miss rate of 1%, a data cache miss rate of 5%, a instruction mix of 40% data accesses, a primary to secondary cache miss penalty of 10 cycles and a secondary cache to main memory miss penalty of 200 cycles and a secondary miss rate of 0.2%, what will be the contribution to total CPI from the cache misses (in decimal)
Answer:
The answer is "0.306".
Explanation:
The Primary to Secondary Memory Instruction miss cycle
[tex]= I \times 0.01 \times 10 = 0.1 I[/tex]
Data miss cycles[tex]= I \times 0.05 \times 10 \times 0.40 = 0.2 I[/tex]
The Secondary to main Memory Instruction miss cycle[tex]= I \times 0.01 \times 200 \times 0.0002 = 0.004 I[/tex]
Data miss cycles[tex]= I \times 0.05 \times 200 \times 0.0002 = 0.002 I[/tex]
Total memory stall cycle [tex]= ( 0.1 + 0.2 + 0.004 + 0.002 ) I =0.306 I[/tex]

How can data be calculated?
Answer:
Data can be calculated by solving an equation
Explanation:
Suppose you are developing a data visualization application DataViz which calls some functions from a statistics library class SuperStats. You recently heard about another statistics library UberStats with supposedly significantly better performance than SuperStats. Explain how you would redesign the DataViz class using the Adapter pattern so that DataViz can be configured at runtime to use either SuperStats or UberStats. Does your design use dependency inversion and/or dependency injection? Explain
Answer:
By using dependency injection, create the adapter to adapt both the DataViz and the UberStats interface as expected.
Explanation:
Adapters are used in Objected-oriented programming to run or convert the output of one class object to another. The DataViz class currently uses the SuperStats class as an adaptee to get and output statistical results.
Write a new code from the scratch is tedious, so, the UberStats class dependencies are injected in the adapter and the DataViz and UberStats class functionalities can be experimented with.
