Answer:
13/19, since we are in a pattern in which the number is added by 2/19 each time 11/19+2/19 would equal to 13/19
Answer:
(k(5)-k(-3))/(5+3)
Step-by-step explanation:
Rate of change is the slope. We can determine the slope by using the following equation:

Where in this case f(x) = k(x) and so we have:

Answer:
91
Step-by-step explanation:
P(1) = 0.25
P(3) = 2P(2) = 3P(4)
P(5) = P(4) + 0.1 = P(6) − 0.1
The probabilities add up to 1:
1 = P(1) + P(2) + P(3) + P(4) + P(5) + P(6)
Write each probability in terms of P(4).
1 = 0.25 + 1.5P(4) + 3P(4) + P(4) + P(4) + 0.1 + P(4) + 0.2
1 = 0.55 + 7.5P(4)
0.45 = 7.5P(4)
P(4) = 0.06
Therefore, P(6) = P(4) + 0.2 = 0.26.
The expected value is the number of trials times the probability.
E = 350 × 0.26
E = 91
Answer: A. . . . . . . . . .
I can’t do that check mark thing so I’ll use ! instead.
!12+2!8-12!2
!12 2!8
2!3+2!8-12!2
!8 2!2
2!3+2x2!2-12!2
2x2!2 4!2
2!3+4!2-12!2
2!3+(4!2-12!2)
2!3-8!2
