The “Allow changes by more than
one user at the same time” option.
In a
group of users, it is very important to create a shared workbook so that
several people are able to update information and track changes in the workbook
at the same time. To do so, one should click on the review tab of the excel sheet and select
share workbook. On the editing tab of the share workbook dialog box, select the
Allow changes by more than one user at the same time check box. Go ahead and
click the advanced tab and select option you would want to use and then click
OK
Answer:
click on the cell
Explanation:
This is a little tricky. We need to first think of the column, then of row, and then click on the corresponding cell. And then we either start typing or move our mouse to highlight the cells. Hence, the correct option here is click on the cell.
Answer:
The correct Answer is 0.0571
Explanation:
53% of U.S. households have a PCs.
So, P(Having personal computer) = p = 0.53
Sample size(n) = 250
np(1-p) = 250 * 0.53 * (1 - 0.53) = 62.275 > 10
So, we can just estimate binomial distribution to normal distribution
Mean of proportion(p) = 0.53
Standard error of proportion(SE) = 
= 
= 0.0316
For x = 120, sample proportion(p) = 
= 
= 0.48
So, likelihood that fewer than 120 have a PC
= P(x < 120)
= P( p^ < 0.48 )
= P(z < 
) (z=
)
= P(z < -1.58)
= 0.0571 ( From normal table )
Depends really. Have you got prior coding experience? The semantics of certain languages are much easier to pick up if you've had prior experience, but it might seem impossible to someone who has minimal experience.
Assuming that you're no older than 15 or 16, I'm going to suggest Python. It's a simple, high-level language that's easier to understand than most languages. If you think you've got enough experience to quickly understand and pick up things, then I'd probably say R is a good language to start with. It's very well-suited for AI and tends to be a favourite for AI researchers.
