Answer:
4/7.
Step-by-step explanation:
This the question in which marbles have to be taken out of a bag. Odds in another word for probability.
Total number of marbles in the bag = 2 Blue + 1 Green + 4 Red = 7 marbles.
Required marbles = 3 red marbles.
Therefore:
P (a red marble is selected in the first attempt) = Red Marbles / Total Marbles.
P (a red marble is selected in the first attempt) = 4/7.
Therefore, the correct answer is 4/7!!!
1.5x=3
First you want to get x by itself so divide both sides by 1.5
3/1.5=2
x=2

Answer:
2) (b) -7
3) (b) 14
Step-by-step explanation:
2) The sum is found by adding the numbers together. Your calculator can help if you can't do it in your head. I usually find it easier to add the positive and negative numbers separately. Of course the 0 can be ignored.
18 + 0 -4 -12 +6 -15 = (18 +6) -(4 +12 +15) = 24 -31 = -7

3) Apparently, we are to assume that George's percentage will apply to the next 40 pitches. Then ...
(number missed)/(number thrown) = 35%
missed = (thrown)×0.35 = 40×0.35 = 14
George is expected to miss 14 of the 40 pitches.
I believe the formula to find the height would be h= 2a/b and if you use that formula and plug in the area (21.7) of each triangle as well as the base (6) then you would get a height of 7.2 cm. I hope this is correct! :)
