Answer: 16 2/3%
Step-by-step explanation:
Given that:
Shape are either square or circle with both equally likely :
Hence,
P(square) = 1/2 ; P(circle) = 1/2
Color are either blue, red or green with the three equally likely ;
P(red) = 1/3 ; P(green) = 1/3 ; P(blue) = 1/3
Probability of creating a green circle :
Independent probability
P(green n circle) = p(green) * p(circle)
P(green n circle) = 1/3 * 1/2
P(green n circle) = 1/6
= 0.16666
(0.16666 * 100%) = 16.6666%
= 16 2/3%
For a parallelogram, we know that there are to pairs of angles that are the same and that all 4 angles add to 360.
2(5x-2)+2(48)=360
2(5x-2)+96=360
10x-4+96=360
10x+92=360
10x=268
x=26.8
Final answer: x=26.8
Hope this helps!
Given:
Total number of coins (Quarters and dimes) = 60
Total amount = $12.45
To find:
The number of quarters and dimes.
Solution:
Let x be the number of quarters and y be the number of dimes.
We know that,
1 quarter = 0.25 dollar
1 dime = 0.10 dollar
Total coins:
...(i)
Total amount:
...(ii)
From (i), we get
...(iii)
Putting this value in (ii), we get




Divide both sides by 0.15.


Putting x=43 in (iii), we get


So, the number of quarters is 43 and the number of dimes is 17.
Therefore, the correct option is b.
I'm thinking 75% because the increase from 4 to 7 is 2
