Answer:
1.) 1/2x
2.) 3a
3.) <10
4.) 8/p
5.) =0
6.) =0.25
7.) x-6=4.5
8.) y/8=3.2
Step-by-step explanation:
For #1 all you have to do is add them together. For #2 it is the same thing. For #3 all you need to do is use the less then (<) symbol with a 10 behind it. For #4 quotient means to divide so all you need to do is put a division symbol between the two factors. For #5 all you have to do is substitute 1.5 for the letter A and subtract them. For #6 all the do is substitute 2.25 for b because you convert the fraction to a decimal which is 25/100 which equals .25 then you divide the two numbers. For #7 the difference mean to subtract so you put x-6 instead of the difference between x and 6, then it equals 4.5 because you convert the fraction which would be 50/100 which equals .50. For #8 all you do is flip the word quotient the a division symbol because quotient means to divide.
48.25 x .20 = 9.65........................
Answer:
(c)
<u>Total number of beads:</u>
(i)
<u>Probability of 2 red:</u>
- P(RR) = 15/25*15/25 = 9/25
(ii)
<u>Probability of no 2 red:</u>
- P(R'R') = 1 - 9/25 = 16/25
