The correct statement comparing the theoretical and experimental probabilities is given as follows:
.
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
The theoretical probability is taken before any experiment. Since the four sections are equal, the theoretical probability is:
T(H) = 1/4.
The experimental probability is taken considering previous experiments. Out of 100 tosses, 28 landed on H, hence:
E(H) = 28/100 = 7/25.
Hence the correct statement is:

Given, the rate of growth of St. Augustine grass is cm per week.
We have to find the number of weeks that the grass grow to cm.
Let's take the number of weeks be x.
In 1 week the grass grow = cm
So in x weeks the grass grow = cm
So we can write,
To solve it for x, first we will move 7 to the right side by multiplying it to both sides. We will get,
Now to get we will move 4 to the right side by dividing it to both sides. We will get,
So we have got the required answer.
After 3 weeks the grass grow .
