Answer:

Step-by-step explanation:
<em><u>Given:</u></em>

<em><u>Solve for:</u></em>

<em><u>Solution:</u></em>
(1) Let's move all of components that do not contain
(our target) to the right side (notice the change of sign of
from negative to positive):

(2) Let's divide both sides of equation by 4:

(3) Now, we simplify the left side:

This is the solution.

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

Answer:
x=11, y=2
Step-by-step explanation:
We can set 1 equal to x-5y and then solve for x. and y.
x = 5y+1
y = x-1/5
We can use this information and plug back in the values for 3y-x or x-5y.
We can set -3 = 3y-x or 1 = x-5y.
To solve for x using -3 = 3y-x we can swap the values of x and y which would make it -3 = 3(x-1/5)-5(x-1/5)+1.
We can do a bit of algebra which would get us x = 11.
Knowing that y = x-1/5 we can plug in 11 for x. y = 11-1/5.
y=2
x=11, y=2
