Answer:
f(x) = x^2 - 3x - 28
Step-by-step explanation:
The root -4 corresponds to the factor (x + 4); the root 7 corresponds to (x - 7). The equation is thus f(x) = (x + 4)(x - 7) = x^2 - 3x - 28, or
f(x) = x^2 - 3x - 28

Step-by-step explanation:
Solution:
Number of babies which are female = 50%=
So, if Population of 50 is considered , and 50% of population is female then out of 25 must be female.
Population of female can't exceed 25.
Probability of an event =
Probability that 20 or more of the 50 babies born today were female
=
Simulation of the Above Situation
If we use a double sided coin and a sign heads us females and Tails as males,Toss the coin 50 times , number of times Heads comes shows number of females born and number of times tails appears shows Population of men.
It may not happen that Number of heads =Number of tails if we toss the coin 50 times.So if number of tosses increases the chances are more likely that , number of heads= Number of tails. But for above problem we just have to toss coin 50 times only, that is
Number of males = Number of females
