Bryanna performed an experiment in which she flipped a coin and recorded the results. She got heads up 23 times and tails up 27 times. Which statements are true about the experimental probability of getting tails up?
The experimental probability is written as a ratio.
The experimental probability compares the number of heads up to the number of tails up.
The experimental probability includes 50 trials.
The experimental probability compares the number of tails up to the number of trials.
The experimental probability compares the number of heads up to the number of trials.

step-by-step explanation:

answer: 100

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
