Step-by-step explanation:
(x+5)^2 = 2( 5x-3)
x^2+25=10x-6
x^2-10x+25+6= 0
x^2-10x+31=0
a=1, b
Answer:
57.1%
Step-by-step explanation:
We know that a coin has only two sides, heads or tails. Therefore if of the 84 times, 36 times he fell in heads, the other times he fell in tails.
84 - 36 = 48 times fell in tails.
Therefore to calculate the percentage that fell in tails, it would be the ratio between the number of times it fell in tails and the total number of experiments:
48/84 = 0.571, and that is 57.1%
Which means that 57.1% of the times the coin was thrown fell into tails.
