there is about a 4% chance that they answer yes and about an 8% chance they are male.

Yes probability- 6/151≈.039 which rounds to .4 or 4%

Male probability- 12/151≈.079 which rounds to .8 or 8%

Y=x+1<br> y=x^2-1<br><br> please help i don't understand
ololo11 [35]

ANSWER

The solution is

(x=1,y=2),(x=2,y=3)


<u>EXPLANATION</u>

We have

y=x+1---(1)

and


y=x^2-1---(2)


Let us substitute equation (1) in to equation (2). This gives us,

x+1=x^2-1(2)

We rewrite this as a quadratic equation as the highest degree is 2.

x^2-x-1-1=0

This implies that


x^2-x-2=0


we factor to obtain,


x^2+x-2x-2=0


x(x-1)-2(x-1)=0


(x-1)(x-2)=0


This means,

(x-1)=0\:\: or\:\:(x-2)=0

x=1\:\: or\:\:x=2


We substitute this values into any of the above equations, preferably equation (1)


When, x=1, y=1+1=2


When, x=2, y=2+1=3


The solution is

(1,2),(2,3)
