Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x=(33/20)
Decimal Form:
x=1.65
Mixed Number Form:
x=1(13/20)
In order to show something on a grid, you need a X and Y coordinate.
bearing in mind that parallel lines have exactly the same slope, hmmmm what's the slope of the line on that table anyway?
well, let's just pick two points off the table to get that slope, say (5,6) and (11,18)
so we're really looking for the equation of a line whose slope is 2 and runs through (0,10),
Answer:
a) All girls - 12C8 /20 C8
b) All boys - 8C8/20C8
c) 4 girls and 4 boys - 8C4 * 12C4/20 C8
d) 3 girls and 5 boys - 8C5 * 12C3/20 C8
e) At least one boy - 1 - 12C8 /20 C8
f) At least two girls 1 - (1 - 8C8 /20 C8)
Step-by-step explanation:
Given -
Total girls - 12
Total boys - 8
a) All girls - 12C8 /20 C8
b) All boys - 8C8/20C8
c) 4 girls and 4 boys - 8C4 * 12C4/20 C8
d) 3 girls and 5 boys - 8C5 * 12C3/20 C8
e) At least one boy - 1 - 12C8 /20 C8
f) At least two girls 1 - (1 - 8C8 /20 C8)
