Answer:
68 students
Step-by-step explanation:
Number of men who major in business in the university= 0.43*8253=3548.79
Rounding off we have 3549 students
Number of women who major in business in the university= 0.27*10327=2788.29
Approximately 2789 students
Total students who major in Business= 3549+2789=6338 students
Total students in school= 8253+10327=18580
Probability of getting business major= 6338/18580
Out of 200 students, we expect
Approximately 68 students will be majoring in business
Perimeter = 2(Length) + 2(Width)
300 = 2L + 2W → 150 = L + W → 150 - L = W
Area = Length · Width
= L(150 - L) →
= 150L - L²
There are 2 different methods for solving (depending on which math course you are taking).
<u>Calculus</u>: find the derivative, set it equal to zero, and solve for L.
= 150L - L² → 0 = 150 - 2L → 2L = 150 → L = 75
<u>Algebra</u>: find the vertex.
= - L² + 150L → L = -b/2a → L = -150/2(-1) → L = 75
Once you solve for L, plug it into the Perimeter equation to solve for W:
150 - L = W → 150 - 75 = W → W = 75
Answer: 75ft x 75ft
