Answer:
option: A
Step-by-step explanation:
" if for a polynomial with rational coefficients has irrational roots then these irrational roots will always appear in pair " .
we are given that 
and 
are two roots of a polynomial equation with rational coefficients, then it's complex conjugate is also a root of this polynomial equation i.e. ' 
' and ' 
' are also roots of this polynomial equation.
Hence, option A is correct.
Answer:
hy dude i don't have exact answer but you can go through below equation
Step-by-step explanation:
A unit rate is a ratio between two different units with a denominator of 1. To calculate the unit rate, divide the numerator by the denominator. The resulting decimal number is the unit rate.
For this case, what you should see is which lines contain point O.
We have then that the lines that contain this point are:
EC
AD
BO
We note that three lines contain point O.
Therefore, three lines intersect at the same point.
Answer:
4. 3
I always used rise over run. which is when you count up the y axis for run and count over on the x axis for the run. then take your rise over run and there is your slope.
Answer:
a) We have evidence of the " center stage effect" pair number 3 was selected 34 times almost double the probability of random process
b) probability of ocurrency in random case is 20 %
Step-by-step explanation:
To answer this question we first look at the probability of chossing a pair in case of random selection
P = successful event / total outcomes
P₁ = 1/5
P₁ = 0,2 or P₁ = 20 %
Then if the central pair was selected 34 times from 100 participants ( almost the double ) we have evidence of the center stage effect
P₂ = 34/100 or P₂ = 0,34
