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:
660
Step-by-step explanation:
Because the ration is 1:5, then 132 chaperones times 5 is 660 students. Please like me and rate!!
Thank you for posting your question here. <span>The first and fourth quadrants will be used. Since x is time you only need positive x values. Since y is temperature you'll need both positive and negative numbers on the y-axis. I hope it helps. </span>
Answer:
Let n be the number of 25 cent stamps.Then, 28 - n must be the number of 29 cent stamps.Tim paid $7.60 the stamps.
0.25n + 0.29(28 - n) = 7.60
This means that n stamps at 25 cents a piece plus (28 - n) stamps at 29 cents a piece sum to $7.60.Solve for m.
0.25n + 8.12 - 0.29n = 7.60
-0.04n = -0.52
n = 13
So, Tim bought 13 25-cent stamps and 28 - 13 = 15 29-cent stamps
Step-by-step explanation:
hope this helps:)
