Answer:
0.6% people had a mild allergic reaction to the shampoo.
Step-by-step explanation:
To find out the percentage of the people who got the mild allergic reaction, we are going to divide the number of people (18) who got the allergic reaction and divide it by total number of people who tried the shampoo (3000) and multiply it by 100.
= * 100
=0.006 * 100
= 0.6%
Answer:
Step-by-step explanation:
Let A = R−{0}, the set of all nonzero real numbers, and consider the following relations on A × A.
Given that (a,b) R (c,d) if
Or (a,b) R (c,d) if determinant
a) Reflexive:
We have (a,b) R (a,b) because ab-ab =0 Hence reflexive
b) Symmetric
(a,b) R (c,d) gives ad-bc =0
Or da-cb =0 or cb-da =0 Hence (c,d) R(a,b). Hence symmetric
