Statistical questions: A, C, E, because they all talk about students, where B and D talk about adults and people in general. Frank just wants to know about students.
Answers:
- sin(C) = 24/25
- cos(Z) = 5/13
=============================================
Explanation:
The formulas we use are
- sin(angle) = opposite/hypotenuse
- cos(angle) = adjacent/hypotenuse
The fraction 15/39 reduces to 5/13 after dividing both parts by the GCF 3.
Answer:
Step-by-step explanation:
14: k^-3/k^4= 1/k^7
15: answer : 1/3²
16: n^-4
17: f-g^4 = 3-(-5)^4 = -622
18: (x^5-y^2)²+x³ =
(2^5-8^2)²+2³ =1032
19: m²-n³
6²-2³ = 36-8=28
20 : 2²×3²×5³= 4500
4500/10 = 450 islands
<h2>4500 x 6700-577=30149423</h2>
