The intersection of sets is composed of the common elements.
The given sets have two common elements: 2 and 5.
<span><span>{2;3;5;7}</span>∩<span>{2;5;11;13}</span>=<span>{2;5<span>}</span></span></span>
7+3+8+3=21 fishes in total
8/21 fishes are healthy
8/21 = 0.4 => 40%
B. Fractions have to have the same denominator so

which =

then you simplfy it to

so it would be B
Answer: The graph is attached.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
We can find "b" substituting the slope and coordinates of the (4,3) into thte equation
, and then solving for "b":

By definition, the line intersects the x-axis when "y" is zero.
Then, we need to substitute the y-intercept and
into
and then solve for "x" in order to find the x-intercept:

Knowing the x-intercept and the y-intercept, we can graph the line (The graph is attached)
