Answer:
P(x < 3) = 0.42319
Step-by-step explanation:
From the given information:
The mean density
3
Let x be the random variable that follows a Poisson distribution.
Therefore:
for x =1, 2, 3...
However, the probability that a random quadrat contains less than 3 spatuletails can be computed as:

P(x < 3) = 0.42319
Answer:
A. y=2x+8
B. y=4x
Step-by-step explanation:
These are both linear equations so use y=mx+b where m is the slope (rate you earn money) and b is the yintercept (starting point).
Tatiana starts at 8 dollars and gains 2 dollars a week so m is 2 and b is 8
Julian starts without any money and gets 4 dollars a week so m is 4 and b is 0
