Answer: 14 students
Step-by-step explanation:
Data: Out of a group of 63 students,
22 study Biology, 26 Study Chemistry, and 25 study Physics
8 study both Physics and Chemistry, 4 study both Biology and Chemistry, 3 study both Physics and Biology, and 1 student studies all three subjects.
Number of people who only take Biology=x
<u>Step one, Add up all of the people who take Biology with another subject</u>
4+3+1=8
Reason, Since we want to find the number of people who only take biology, we have to find the number of people who take Biology with another subject so we can seperate them later in the problem.
<u>Step two, Subtract the number of people who take Biology with another course with the number of people who take Biology as a whole</u>
22-8=14
Reason: Since we know how many people take biology with another course, we can subtract that from the people who take Biology in general to get the number of people who only take Biology.
That's how we get to our answer of 14 students
I hope this helps!

<span>A child weighing 28 pounds would have to take 15 milligrams of medicine in order to receive and adequate dose, if the adult dosage is 80 milligrams. For the child to receive the full adult dosage of 80 milligrams, the child would have to weigh 150 pounds.</span>
Point G(4, -2)
Point H(-1, 10)
We want the distance of line segment GH.
Use the distance formula for points.
Note: d(G, H) means the distance from point G to point H.
d(G, H) = sqrt{(10 -(-2))^2} + (-1 -4)^2
d(G, H) = sqrt{(12)^2 + (-5)^2}
d(G, H) = sqrt{144 + 25}
d(G, H) = sqrt{169}
d(G, H) = 13

Answer:
Option C
Step-by-step explanation:
To answer this question you must use the parallelogram method shown in the attached image.
To answer this question, use the parallelogram method as shown in the attached image.
-Place the vectors a and b at the same point of origin.
-On the tip of the vector b draws a vector a.
-On the tip of vector a to draw a vector b.
-Draw a vector "f" that goes from the origin to the corner of the parallelogram.
The vector "f" represents the sum of the vector a with the vector b.
The correct option is C
