BITS wants to store information about the supervisors, including their supervisor number and the relationship to consultants. Su
Olin [163]

Answer:

Convert the table into normalize form

Explanation:

Un normalized relation of the given schedule is as

Consultant ( ConsultNum, Last Name, First Name, Street, City, ZipCode

HoursRate (SupervisorNum, Supervisor Num)

(Tasks, Description, Catagory, Price, SupervisorNum))

According to these functional dependencies :

SupervisorNum is dependencies of the SupervisiorNum

ConsltNum is dependencies of the Last Name, First Name, Street, City, ZipCode, Hours, Rate

Tasks are dependencies of Description, Category, Price

The consultant table is not in a normalized form as it contains repeating groups. Make composite keys such as Supervisor Num, Tasks and ConsltNum and convert the table in NF by removing repeating groups

Such as table in NF

Consultant

(Consult Num, Last Name, First Name, Street, City, Zip Code, Hours, Rate

Supervisor Num, Supervisor Name, Tasks, Description, Category, Price)

Todd insisted on having an image to go with every slide. Is this good or bad?
valentina_108 [34]

Answer:

Yes, Its a good idea but depends upon type of image. Like adding a logo to all the slides at top left corner is not just good but a must for all as well, when we are preparing official documents. However, other images when decided to be repeated must convey the correct intent in each page. If this is not the case, you need to avoid it. Intent is the most important aspect certainly. For rest see explanation.

Explanation:

Yes, and as mentioned above adding logo and other images meaningfully, and with correct intent is a good idea.

However, images must not be blurred, tiny or stretched. Also proper cropping is a must. The border should be solid as well. And when selecting a lot of images, the images must convey the correct meaning together. Moreover, the aspect ratio after stretching must be same as the original. You can do this in PowerPoint by going to format > crop > fill.

Ensure that watermarks are not revealed. Buy them rather than copy from somewhere for better outcome. And never amputate your readers with a headache creating backgrounds. You will loose readers then. The clip arts must be used in right number, and not a lot of them certainly.

Ensure both text and images are in correct ratios. Avoid using more than 2 images per slide.

Supposethatyoubet$5oneachofasequenceof50independentfairgames. Usethecentrallimittheorem to approximate the probability that you
lions [1.4K]

Answer:

0.119

Explanation:

50 independent fair games

Mean will be 50/2 = 25

Standard deviation of the loosing probability is :

\sqrt{50*0.5*0.5} * 10 = 33.536

we have to loose 33 times out of 50 games.

To find the approximate probability we use z- value table.

z value =  \frac{33-25}{3.35}

z - value = 2.2659

Looking at the z-value table we get 0.119.
