Ratio is 6:5
6+5=11
Men: 6 parts of 11 = 3600
6=3600
1=x
X=3600/6
=600.
Women: 5 parts of 11
1 part = 600
5 parts = 600x5
=3000
The table below shows the outcome of tossing 3 coins
The probability of getting two heads is 3/8
If the three coins tossed 10000 times, the probability of exactly two heads appear is = (3/8) × 10000 = 3750 times
I believe that you will use the distance formula d=x2-X1^2+y2-y1^2
Solution
To find out which expressions represent the difference of exactly
two expressions
a) 6(x+7) - 2
This can be simplified as
6x + 42 - 2
6x + 40
Clearly this does not represent difference of the two
expressions .
b) -2j
Clearly this represents a single expression , this does not represent
a difference of 2 expression .
c) 4f - 2g
Here we have 2 different expressions 4f and 2g
Difference of these 2 expressions are 4f - 2g
Hence , this option represent difference of exactly two
expression
d) 3xyz - 10
3xtz - 10 represnts a single expression
Here we have a single expression
Therefore it does not represent difference of exactly 2
expression .
2x + y = 8
3x - y = 17
---------------add
5x = 25
x = 25/5
x = 5
2x + y = 8
2(5) + y = 8
10 + y = 8
y = 8 - 10
y = -2
solution is (5,-2).....this is consistent and independent because it has one solution
