There is a 3/10, 0.3, and 30% chance of selecting cheesecake then a 4/10, 0.4, 40% chance on selecting cookies.

There is a 3/10, 0.3, 30% chance of a person selecting and eating a apple pie and the chance of them selecting another apple pie is 2/9, 0.22222222, 22.2222%.

There is a 4/10, 0.4, 40% chance somebody selects a cookie and gives it to their friend and their is a 3/9, 0.33333333333333, 33.3333% of someone selecting cheesecake randomly.

There is a 3/10, 0.3, 30% percent chance of someone randomly selecting a apple pie then putting it back and there is a 4/10, 0.4, 40% chance of someone selecting a cookie.

There is a 3/10, 0.3, 30% of someone randomly selecting a cheesecake and eating it and there is a 3/9, 0.33333333333333, 33.3333%. I hope this helps but i am a little unsure if for example it says what r the chances of someone RANDOMLY selecting lets say a cookie and lets say the fraction is 3/10, 0.3, 30% and lets say they put it back then it says what are the chances of someone selecting cheesecake but it doesn’t say randomly lets say there are three cheesecakes would the fraction, decimal, and percentage be a hundred percent chance on all of the things because it wasn’t picked randomly?

And another thing is lets say for number 1 someone takes a cheesecake and eats it. Would that affect the number of cheesecakes for the other questions?



ANYWAY I ANSWERED YOUR QUESTIONS THE BEST I COULD IM SORRY IF SOME WERE WRONG ALTHOUGH I DON’T THINK THEY ARE I DON’T KNOW WHAT PEOPLE MEAN BY THEY WOULD GIVE BRAINLIEST BUT IF YOU KNOW HOW OR YOU CAN WILL YOU GIVE IT TO ME.

Explain whether or not the plant labeled p(x)=x2+x+3 has any rational or irrational roots.
olasank [31]

frational roots are those numbers that can be written in form \frac{a}{b} where a and b are integers (integers are like -5,-4,-3,-2,-1,0,1,2,3,4, etc)

some examples are 1=1/1, 2=2/2, -4=-4/1, 4/3, 0.111111111111=1/9, etc

irrational numbers are numbers that can't be written that way like pi

numbers that involve √-1 or a square root of any negative number are called complex numbers and are neither rational nor irrational.


roots are the values of x that makes the function equal to 0


p(x)=x^2+x+3

set equal to 0

0=x^2+x+3

I can't factor so use quadratic formula

for 0=ax^2+bx+c

x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}

so

x=\frac{-1 \pm \sqrt{1^2-4(1)(3)}}{2(1)}

x=\frac{-1 \pm \sqrt{-11}}{2}

√-11 is a square root of a negative number so it is a complex number. therefore, the function does not have rational or irrational roots


p(x) has no rational or irrational roots
