Step-by-step explanation:
(x-2) (x+4)=0
x-2=0
x=2
x+4=0
x= -4
Answer:
Lets assume that 1200 births are randomly selected and exactly 595 of the births are girls.
In percentage this is : 
This is approx 50%. We can say that almost random 50% are girls.
So, It is unlikely because the probability of this particular outcome is very small, considering all of the other possible outcomes.
Part B: It is not unusual because 595 is about the number of girls expected.
Answer:
Step-by-step explanation:
(4,1/3) and has a slope of 3/4
y - y1 = m(x - x1)
m = 3/4, y1 = 1/3, x1 = 4
y - 1/3 = 3/4(x - 4)
Multiply each term by 12
12y - 4 = 9x - 36
12y = 9x - 36 + 4
12y = 9x - 32
y=-2x+1
So, -2x, you go down 2 every time you go across 1. So, the rise is -2, and the run is 1, so it's -2x
+1: when you reach an x of 0, you are still up 1. So, the y-intercept is 1
Answer:
When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field. The piece of iron has become a magnet. Some substances can be magnetized by an electric current.
