Answer:
28/55
Step-by-step explanation:
total no of beads are 11
red beads are 7
and white beads are 4
no of ways to take 2 beads from 11 beads are 11c2
that is( 11*10)/2=55
no of ways to take 1 red bead from 7 is 7c1 that is 7
no of ways to take 1 white bead from 4 is 4c1 is that is 4
required probability is( 7*4)/55=28/55

Answer:
The answer is 4.2 kilograms of dog food
Step-by-step explanation:
it says that ray feeds his dog 0.12 kilogram of food each day
he needs for 1 month
1 month = 31 days or 30 days
since 1 day food is 0.12 kilograms you'll have to multiply 0.12 with 1 month
i.e; 0.12*31 or 0.12*30
0.12*31=3.72 and 0.12*30=3.6
since we don't have an option we'll have to choose something bigger than this
therefore, the answer is 4.2

Answer: a = 1 b = 7
Step-by-step explanation:
x^2(y^3)^4/x.y^5 = x^a.y^b
x^2(y^12) = x^a.y^b
(x^2).(y^12)/x^y^5 = x.y^7
x.y^7= x^a . y^b -> <u>x^1.y^7</u>
