Answer:
the second option: 1/5
Step-by-step explanation:
there are 30 total women, and 6 have both belts and purses. this means that the probability of them having both is 6/30= 1/5
Conversions aren't bad until you have to deal with the cubed and squared versions of them!! Remember that there are 100 cm in 1 meter. If that be the case, then there are 100cm*100cm*100cm (100cm^3) in m*m*m (1 meter cubed). We will use that in our conversion then:
. The cm^3 cancels out leaving m^3 over m^2 which is what we want. Doing the math now we get
, or
What you would have to do is distribute your three to each number in the parentheses using multiplication so your answer would be 6y+15
Answer:
the total time is 18 hours remaining
Let x be the score of the 3rd quiz,, then the average score will be:
(83+91+x)/3, which = (174+x)/3. but this average should be greater or equal to 85 and smaller or equal to 90:
85 ≤ (174+x)/3 ≤ 90
1st multiply all terms with 3 → 255 ≤(174+x) ≤ 270
2nd subtract 173 from all terms → 255-174 ≤174-174+x ≤270-174
81 ≤ x ≤ 96
