Each month, a Filipino household generates an average of 28 pounds of newspaper for garbage or recycling. Assume the standard deviation is 2 pounds. If a household is selected at random, find the probability of its generating more than 31 pounds. (
r+4s+t+rt-s²=0
Form the PDE of the following by eliminating arbitrary functions from:
1.xyz=(x^2+y^2-z&^2)
2 . z= (x+y)f(x^2-y^2)
Find the expected value of the random variable X and its variance having the following density function details explanation
f(x) = 5 (1-x4) 0<x<2
= 0 elsewhere

A tumor is injected with 0.9
grams of Iodine-125, which has a decay rate of 1.15%
per day. Write an exponential model representing the amount of Iodine-125 remaining in the tumor after t
days. Then use the formula to find the amount of Iodine-125 that would remain in the tumor after 60
days.
a population consists of three numbers (1,3,5,8 & 11). Consider all possible sample of size 2. which xan be drawn without replacement from the population.
Direction: Complete the table below by constructing and illustrating the
probability distribution of Example 3 (refer to page 7).
Solution
Steps
1. List the sample space
2. Count the number of tails
in each outcome and
assign this number to this
outcome.
3. Construct the frequency
distribution of the values of
the given random variable.
4. Construct the probability
distribution of the given
random variable by getting
the probability of
occurrence of each value of
the random variable.
5. Construct the probability
histogram
Suppose the mean number of days to germination of a variety of seeds is 34, with a standard deviation of 4.3 days. What is the probability that the mean germination time of a sample of 250 seeds will be within 0.5 days of the population mean?
