Hwy friend
Let's figure this out.
5+7+4+4= 20 total students
4/20 students have hazel eyes
6/20 students do not have hazel eyes
16 / 20 =.8
80% chance that 1 is not hazel
80% that the 2nd isn't hazel
To find the probability that both will not be hazel you must multiply:
80% by 80% (.8 * .8)
.8 *.8 = .64
There is a 64% chance both of the selected students wont have hazel eyes.
Divide 13 by 20 and that is 0.65 so you add that to 4 which is 4.65.
18000 divided by 360, then multiply that new number with 48. i believe that is the correct math...<span />
Answer:
it would be 12 multiple by 9 then add the 5 centimeters
Step-by-step explana
So in this case expand the brackets where everything outside the brackets are multiplied into the brackets if that makes sense. Therefore 5 times 3m plus 5 time 2.
(5×3m)+(5×2)
=15m+10
do not add them together since they are not like terms
Do the same for the next question
which I think is already done for you since there is no expanding or adding to do.
Hope I am right if not sorry.
