HURRY 15 points What happens to the mode of the data set shown below if
the number 20 is added to the data set?

18,24,19,21,19,19,18,20,15,26 ,25,19,17,20,24,21,26
A there is no mode
Bthe mode will not be changed
C there will be two modes
D the mode increases by 6

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

the answer is 5/14.

hope this .

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

y - 25 = 2 ( x - 10 ) should be the answer
