Answer:

Total number of outcomes = 23

number of biology and art students = 2

number of biology students = 2

Since it is given that all the students study art,

number of possible outcomes = 2

probability = number of favorable outcomes/number of total outcomes.

= 2/23

Therefore probability that the selected student studies both art and biology is 2/23.

43/645= I need the to show the work

Licemer1 [7]

I'm guessing you need 43/645 simplified:

First, we need to find the greatest common factor (GCF) of the numerator (43) and the denominator (645). To do so, we list all the factors of each number and find the common ones.

Factors of 43: 1, 43
Factors of 645: 1, 3, 5, 15, 43, 129, 215, 645

Out of the listed factors for each number, which numbers are common between the two? The common factors are 1 and 43. Since we are looking for the GREATEST common factor, which number out of 1 and 43 is the greatest? The GCF is 43.

Second, we can now divide the numerator (43) and the denominator (645) by the GCF we recently found which was 43.

$43 \div 43 = 1 \\ 645 \div 43 = 15$

Third, our new simplified fraction is 1/15. We collected our new numerator and denominator.

Sandra saves 12% of her salary for retirement. This year her salary was $3,000 more than in the previous year, and she saved $4,

slava [35]

So since we know she saved 12% in the previous year so you would make a graph and then draw 100 squares now since 12 dosen't go into 100 evenly you would multiply 12 until you get 96% (which is multiplying 12 by 8) then her salary would be $4,200 dollars multiplied by 8 which is 33,600 dollars then to get your 4 more percent you would divide 12 by 3 which is 4 and you would also divide 4,200 by 3 which is 1,400 and add that to 33,600 dollars and her salary would be 35,000 dollars in the previous year her current year salary would be 38,000 dollars.
