Complete Question
In a country in which people only want Girls, every family continues to have children until they have a Girl. If they have Girl, they stop. If they have boy, they will continuous have child. Assuming that the birthrate of Girl is 52%, what is the proportion of Girl in the country?
Answer:
0.52
Step-by-step explanation:
From the question we are told that
52% is the birthrate of Girls
Therefore
0.52 is the proportion of Girls to boys in that country
Are you asking how to solve for k? In that case, multiply both sides by 4. Then add 3 to both sides:
(k-3) = 40
k = 43
Hello!
To solve the problem, we must isolate x to determine what it is equal to.
4x = -36
x = -36/4 (we isolated x by dividing it on both sides)
x = -9
We can determine that x is equal to -9
I hope this helps you! Have a lovely day!
Answer:
x = 5/6-4y^2
Step-by-step explanation:
^ = to the power of and * = times
y = square root of 6x-5/4x
(times by the square root on either side, sorry I don't know how to word it)
y^2=6x-5/4x
(times by 4x either side)
4xy^2= 6x-5
(+5 either side)
4xy^2+5=6x
(-4xy^2 either side)
5=6x-4xy^2
(factorize)
5=x(6-4y^2)
(divide by (6-4y^2))
5/6-4y^2 = x or x = 5/6-4y^2
Tell me if this is incorrect.
