Solution:
Total number of students=273
Let x students choose Tiger. Then we can write
Number of students who choose Bulldog
Number of students who choose Lion
So we can write
Hence a total of 39*2=78 student choose Tiger.

2 - 3i is just another of writing (2, -3) in the cartesian plane, the 2-3i however is using the "imaginary axis" for the imaginary plane, is all however the imaginary axis is simply the equivalent of the y-axis. Likewise 9+21i is just (9,21), so let's just use the distance formula.
Answer:
Equation:
The point (0,-5), (0,7), (5,0) and (-7,0)also lie on this circle.
Step-by-step explanation:
We want to find the equation of a circle with a diamterhat hs endpoints at (-3, 4) and (5, -2).
The center of this circle is the midpoint of (-3, 4) and (5, -2).
We use the midpoint formula:
Plug in the points to get:
We find the radius of the circle using the center (-1,1) and the point (5,-2) on the circle using the distance formula:
The equation of the circle is given by:
Where (h,k)=(-1,1) and r=√37 is the radius
We plug in the values to get:
We expand to get:
We want to find at least four points on this circle.
We can choose any point for x and solve for y or vice-versa
When y=0,
The point (5,0) and (-7,0) lies on the circle.
When x=0
The point (0,-5) and (0,7) lie on this circle.
Answer:
In 16170 ways the committee can be formed.
Step-by-step explanation:
3 faculty members and 5 students are required to form a committee.
The eligible to serve on the committee are 7 faculty members and 11 students.
If each committee position has the same duties and voting rights.
Then, the number of ways of selecting 3 faculty members out of 7 eligible faculty members is .
Again, the number of ways of selecting 5 students out of 11 eligible students is given by .
Therefore, in (35 × 462) = 16170 ways the committee can be formed. (Answer)
