The independent variable is your input (x-value) and the dependent variable (y-value) depends on what the input is.
y = 10x
y is total money earned
x = number of lawns mowed
The first answer listed
The theoretical probability of getting heads or tails is 1/2 the time.
1/2 of 150 = 75
So theoretically you would get 75 heads and 75 tails.
The experiment got 84 heads, which is greater than 75, so it would be higher than the theoretical probability.
The answer is : <span>It is 6% higher than the theoretical probability.</span>
12.5 is already a decimal...
If you mean 12/5, then it is 2 and 2/5, which is 2.4.
If you mean 12 x 5, then it's 60.
If you mean fractions equivalent to 12.5 then it's 25/2.
If you mean decimals then 12.50, or 12.500.
Hope this helps
