The density curve for a continuous random variable X has which of the following properties?

(A) All of the answer options are correct.
(B) The total area under the density curve for X must be exactly

(1) The probability of any event of the form X = constant is 0. The probability of any event is the area under the density curve and above the values of X that make up the event.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

y=mx+b

step-by-step explanation:

m slope, b y-intercept

3

step-by-step explanation:

no because after the troops were pulled many blacks were killed by hangings lynchings and other cruel ways which in a way interrupted the reconstruction of the south and differed from the way abraham lincoln had an idea of reconstruction
