Answer:
The probability is
Step-by-step explanation:
From the question we are told that
The population proportion is
The mean of the sampling distribution is
The sample size is n = 600
Generally the standard deviation is mathematically represented as
=>
=>
Generally the probability that the proportion of airborne viruses in a sample of 600 viruses would differ from the population proportion by greater than 3% is mathematically represented as
=>
Now add p to both side of the inequality
=>
=>
Now converting the probabilities to their respective standardized score
=>
=>
=>
From the z-table
and
So
=>
A) Let b and r represent the cost of a bag of bark mulch and red mulch, respectively. (Always start with a "let" statement that defines your variables--usually based on what the question is asking: cost of each type.)
8b +6r = 44.50 . . . . Paul's first purchase
1b +8r = 25.50 . . . . .Paul's second purchase
b) There are many ways to solve a set of linear equations like this. I like a graphical calculator because it gives me the solution without having to think too much or do any arithmetic.
(b, r) = (3.50, 2.75)
Pine bark mulch costs $3.50 per bag.
Red mulch costs $2.75 per bag.
c) The project cost would have been
.. 14*$3.50 +10*$2.75 = $76.50
Paul would NOT have been able to make that purchase with funds available.
