Answer 23

(9/10) (7/4) what does parehtheses mean?

Answer 24

it means u multiply the fraction 9/10 by the fraction 7/4. when multiplying fractions u multiply top by top and bottom by bottom

so (9/10) (7/4) = 63/40

Answer 48

kris algebra class has only 23 computers for the 40 students in class.what is the likelihood that kris will have to share a computer with another student in the class?

Answer 49

are u still there

Answer 50

yes beauty - i'm still thinking -i'm not sure of this but i think the probability is 100 per cent as there are more students than computers are u sure u have the numbers right?

Answer 51

yes im sure

Answer 52

oh - hold on - my heads not working - 34 will share 17 computers and the other 6 will have a computer of their own - so the probability of sharing is 17/23

Answer 53

how did u get that 34 share 17 computer

Answer 54

i did this by thinking of two numbers to fit 2x + y = 40

Answer 55

so the lielihood will be 17/23?

Answer 56

yes -perhaps i haven't explained it very well - its really an algebra problem Have u done any algebra?

Answer 57

not really

Answer 58

right - well without algebra its a metter of guesswork and trial. What u have to think ofis what 2 numbers when added together make 23, and when one of them is X by 2 (that is two sharing a computer) and the other is added make 40.

the only 2 numbers which fit are 17 (sharing) and 6 have a computer on their own

in algebra u let x = no of computer shared and y = no. not shared, so

x + y = 23
2x + y = 40
and there is a way to solve these 2 'equations' to give u the answers

u will learn this in future

Answer 59

so 17 of the computers are shared so probability = 17/23

Answer 60

i have to go now beauty to go to dinner. hope i've helped you.
