Compare the theoretical probability to the experimental probability of landing on H.
cestrela7 [59]

The correct statement comparing the theoretical and experimental probabilities is given as follows:

\frac{1}{4} < \frac{7}{25}.

<h3>What is a probability?</h3>

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:

\frac{1}{4} < \frac{7}{25}.

(a) need to find the number of books, we'll call it "b". then the money (6w) minus the cost of books (17b) equals change left over (w)
6w - 17b = w
6w - w = 17b
5w = 17b
(5/17)w = b

(b) if w = 34
(5/17) *34 = b
10 = b

What is the value of x?<br> 21<br> 24<br> 32<br> 44
VMariaS [17]

Answer:

x = 21

Step-by-step explanation:

Because GJ is a diameter, the angle K is a right angle (90 degrees).

Thus, 4x + 6 = 90, and 4x = 84.  Thus, x = 21
