Step-by-step explanation:
The second one is the correct equation. The constant to the right should be the diameter squared, while the numbers inside the parentheses should be the opposite.
<span>Outcome Heads Tails
Relative Frequency 0.69 0.31
so first statement is false as 69% is close to 70%.
second statement is false as heads probability is close to 70%
last 2 statements are true:
</span><span>The theoretical probability of tails is most likely 30%.

Y=mx+b
y=(1200-2x)/3
y=1200/3-2/3x
y=400-2/3x
y=-2/3x+400
The total participants were:
30 + 50 + 40 + 10
= 100
Out of which:
30 were 0-19 years old
50 were 20-39 years old
40 were 40-59 years old
10 were 60-79 years old
