Answer:
The relation is reflexive as
(1,1),(2,2),(3,3)∈R
(2,1)∈R will not imply (1,2)∈R,
hence R is not symmetric
(2,1),(1,3)∈R doesn't imply (2,3)∈R, hence R is not transitive

Answer:
6.7 units
Step-by-step explanation:
The distance between two points can be found using the formula below:
Thus, distance between (-1, 2) and (2, -4)
![= \sqrt{( - 4 - 2)^{2} + { [2-(-1) ]}^{2} }](https://tex.z-dn.net/?f=%20%3D%20%20%5Csqrt%7B%28%20-%204%20-%202%29%5E%7B2%7D%20%2B%20%20%7B%20%5B2-%28-1%29%20%5D%7D%5E%7B2%7D%20%20%7D%20)
= 6.7 units (nearest tenth)

Answer:
900
Step-by-step explanation:
Margin of error = critical value × standard error
The margin of error is given to be 0.05.
At 99.5% confidence, the critical value is z = 3.
The standard error for a proportion is √(pq/n). Since p is not given, we will assume p = 0.5.
0.05 = 3 √(0.5 × 0.5 / n)
n = 900
