4. the manager of a large store that sells tv sets wants to set up a display of all the different tv sets that they sell. the manager has seven different tvs that have screen sizes between
37 and 43 inches, nine that have screen sizes between 46 and 52 inches, and twelve that have screen sizes of 55 inches or greater.
a. in how many ways can the manager arrange the 37- to 43-inch tv sets?
b. in how many ways can the manager arrange the 55-inch or greater tv sets?
c. in how many ways can the manager arrange all the tv sets if he is concerned about the order they were placed in?

a. 5040 ways

b. 479001600 ways

c. 3.048883446*10²⁹ ways

Step-by-step explanation:

The problem is a permutation problem, where

37 - 43 inches TV = 7

46 - 52 inches TV = 9

Greater than 55 inches TV = 12

Total TV = 7 + 9 + 12 = 28

a) Arranging the 37 - 43 inches TV ( n = 7)

b) Arranging the greater than 55 inches TV ( n = 12)

c) Arranging all the TV ( n = 28)

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
