Cuz she divided 23 and 8 and got 21 then she added 3+3= 6 + 4= 10
X = 6 cos(t)
y = 3 sin(t)
we can rewrite these equations as:
Taking squares of both equations we get:
Adding both the equations, we get:
20% was, so 100%-20%=80% was not
80%=0.8
0.8*4000=3200 acres was not
This is question of probability finding using bayes theorem
It is used to calculate probability of two competing statements
now p(m) = .55
p(~m)= .45
now for basketball for male
p(b|m)=.30
and for female
p(b|~m)=.20
so by bayes theorem
p(m|b)=p(b|m)*p(m)/(p(b|m)*p(m)+p(b|~m)*p(~m))
so answer is E
(.55)(.30) / (.55)(.30) + (.45)(.20)
If there are 189 children, then there are 189 divided 7 = <em>27 groups of 7 children.</em>
As mentioned in the problem,<em> for every 7 children, there are 2 caretakers </em>therefore, there are a total of 2 x 27 = 54 caretakers in the local daycare.
So, in total, there are 189 children + 54 caretakers = 243 people in the daycare facility.
