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:
4.45 but you cant have half a box or tile so 5
Step-by-step explanation:
I got the answer 8x^3+1 by putting the values in the above formula
Answer:
Length = 10
Step-by-step explanation:
Normally you would use
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
But the 2 y values are the same so y2 - y1 = 0.
d then becomes sqrt(x2 - x1)^2
d = (x2 - x1) because the square root of (x2 - x1)^2 is just (x2 - x1)
x2 = 7
x1 = -3
d = (7 - - 3) = 10
114 rabbits are released in an isolated area free of predators
When month =0 , the rabbits = 114
3 years = 36 months
When months = 36 , then rabbits = 912
(0,144) and (36, 912)
Exponential growth equation is y = ab^x
Plug in each point and solve for 'a' and 'b'
so a= 114
(36, 912)
Divide both sides by 114 and then take 36th root on both sides
8 = b^36
b = 1.05946
so exponential equation is 
x is the number of months and y is the population
to find the population be after another 3 months
Plug in 36+3= 39 for x and find out y
y= 1084.43336
so , 1084 rabbits after another 3 months
