Answer:
5, 10 and 16
Explanation:
The sum of their ages is √961 = 31
If Joe is x years old, the equation that follows is:
x + (x+5) + (x+5+6) = 31
This simplifies to
3x = 31 - 11 - 5 = 15
so x=5
From that you can find
Joe = x = 5
Kate = x+5 = 10
Jody = x+5+6 = 16
Answer:
=AND($C11 = "Yes", $D11 = "Yes")
Explanation:
The AND function takes conditional inputs and tests if each of them are TRUE. If all of the inputs are TRUE, the function will output TRUE but if any one of them are not the function will output FALSE. This scales to multiple inputs but this example only has two conditions. It is important to remember that we want to compare a string so our condition must be "Yes", not just Yes.
We also use a relative cell reference, "$", on the columns C and D since we always want to use the "Runner on 1st" and "Runner on 2nd" columns.
Answer:
B. until another thread issues a notify on the semaphore.
Explanation:
A semaphore is a variable that is shared between threads and is not negative. It also acts as a calling mechanism that uses two atomic operations wait and signal for synchronization of processes.
A thread that is waiting for a process can be signaled by another thread.
A semaphore puts a thread to sleep until another thread issues a notify on the semaphore.
The wait operation will get a semaphore or otherwise wait if the busy S semaphore is available.
The signal operation will release a semaphore or wake a process if there is a thread waiting for S.
DDoS - Distributed Denial of Service
<u>Explanation:</u>
- In DDoS attack, the attack comes from various system to a particular one by making some internet traffic.
- This attack is initiated from various compromised devices, sometimes distributed globally through a botnet. It is different from other attacks such as (DoS) Denial of Service attacks, in which it utilizes an unique Internet-connected device ( single network connection) to stream a target with the malicious traffic.
- So in DDoS, multiple systems are involved in the attack and hence we can conclude that as the answer.
They are probably looking for B. subscribing to journals is a good way of keeping up with what's happening in any field.
Of course, a very carefully curated professional network online is great for this too (but they said "personal" so that's not the answer)
Employers generally prefer that employees WORK as often as possible, so even though JUDICIOUS use of social media is a great way to keep current, D isn't the answer either.
Blogging about personal experiences is not necessarily going to teach you anything about work, though blogging professionally can be useful in gathering response from your readership
