Answer:
C) x = 8√3 ; y = 4√3
Step-by-step explanation:
In this figure, the triangle is 30°-60° right triangle.
So x/12= 2/√3, y/12 = 1/√3
Answer:
Step-by-step explanation:
Given that about 40%of babies born with a certain ailment recover fully. A hospital is caring for seven babies born with this ailment.
Each baby is independent of the other and there are exactly two outcomes, recover and not recover.
Hence this experiment is a binomial experiment.
Success is a child getting recovered from this ailment.
p = Probability for any one child to get success = 0.40
The problem consists in changing a fraction to percent form, a percent is a quantity divided by 100, for example, 50% is equal to 50/100, so lets modify the fraction for it to have 100 as denominator.
so we divide the numerator and denominator by the same number so the fraction does not alterate, keeps being equivalent that is:
2/300
we need to divide the numerator and denominator by 3:
<span>2/300 = (2/3)/(300/3)
</span>= (2/3)/100
now we have it, 2/300 as percent is (2/3)% = 0.67%

The correct answer is:
b.) f(n) = 3 • (-2)^(n-1)
Further explanation:
Given sequence is:
3, -6, 12, -24, ...
We have to find the common ratio first.
Common ratio is the ratio between two consecutive terms of a geometric sequence.
It is denoted by r.
So,
General formula for geometric sequence is:
Putting the values of a1 and r
Hence,
The correct answer is:
b.) f(n) = 3 • (-2)^(n-1)
