Find the zeros of the function: f(x) = x^2 - 4x - 21

Mathematics
1 answer:
IrinaK [193]3 years ago
5 0

Answer:

x = 7, x = -3

Step-by-step explanation:

We can find the zeros by factoring the equation using the zero product property.

x^2-4x-21 = 0

(x-7)(x+3) = 0

<u>x-7 = 0</u>

x = 7

<u>x+3 = 0</u>

x = -3

Zeros are x=7 and x= -3.

What is the probability that a family of 4 children will have all girls?
Alex73 [517]
Since as of now we're saying that the probability of having a girl is 1/2, we can say:
1/2 * 1/2 * 1/2 * 1/2, because then you're saying a one half chance of having a girl times another one half chance of having a girl, etc.
 That ends up to be 1/16.
