Answer:
A) I) 49 teams
II)63 teams
B) 28 teams
Step-by-step explanation:
A) a team of 5 boys and 6 Girls
=7C5+ 8C6
= 21+28
= 49 teams
a team of 6 boys and 5 girls
= 7C6 + 8C5
= 7+56
= 63 teams
B) one girl is kept constant already and a guy has injury
Girls remaining to choose from 7
Boys remaining to choose from 6
= 1 +7C5 + 6C5
= 1+21+6
= 28 teams
Answer:
l = 
Step-by-step explanation:
a = lb ( isolate l by dividing both sides by b )
= l
The ratio is equivalent because 1/20 is 5 which means 9/10 is equal
Answer:
B
Step-by-step explanation:
<em>y</em><em>=</em><em>kx</em><em>+</em><em>m</em>
<em>k</em><em>=</em><em>y2</em><em>+</em><em>y1</em><em> </em><em>/</em><em> </em><em>x2</em><em>+</em><em>x1</em><em> </em>
(3,5) and (7,9)
k=(9-5)/(7-3)=4/4=1
Now we want to find out what <em>m</em><em> </em>is. This is by inserting a point in the equation of the line y=kx+m.
so I'll pick (3,5)
5=1×3+m
m= 2
To check if it's correct we could try it with the other point, (7,9).
9=1×7+m
m=2
Therefor the equation would be. y=1x+2
