So if we have 4x^2 - 27 = 0 then by using the square root properties we get:
4x^2 = 27
x^2= 27/4
x= +/- sqrt(27/4)
x=+/- 3*sqrt(3)/(2)
hope this helps! any questions please just ask! Thank you!!
Answer:
no solutions
Step-by-step explanation:
b-9-b=-18
Combine like terms
0b -9 = -18
-9 = -18
This is never true, so there are no solutions
Probability someone chosen at random will not have brown hair = 1/6
<h3>Probability of two variables</h3>
The number of girls = 15
The number of boys = 15
The total number of children = 15 + 15 = 30
Probability that someone chosen at random will have a brown hair, P(Brown hair) = 5/6
P(Brown hair) + P(Not Brown hair) = 1
5/6 + P(Not brown hair) = 1
P(not brown hair) = 1 - 5/6
P(not brown hair) = 1/6
Therefore, if someone is chosen at random, probability that they will not have brown hair = 1/6
