notsponge [240]

The question given is incomplete, I googled and got the complete question as below:

You are a waterman daily plying the waters of Chesapeake Bay for blue crabs (Callinectes sapidus), the best-tasting crustacean in the world. Crab populations and commercial catch rates are highly variable, but the fishery is under constant pressure from over-fishing, habitat destruction, and pollution. These days, you tend to pull crab pots containing an average of 2.4 crabs per pot. Given that you are economically challenged as most commercial fishermen are, and have an expensive boat to pay off, you’re always interested in projecting your income for the day. At the end of one day, you calculate that you’ll need 7 legal-sized crabs in your last pot in order to break even for the day. Use these data to address the following questions. Show your work.

a. What is the probability that your last pot will have the necessary 7 crabs?

b. What is the probability that your last pot will be empty?

Answer:

a. Probability = 0.0083

b. Probability = 0.0907

Step-by-step explanation:

This is Poisson distribution with parameter λ=2.4

a)

The probability that your last pot will have the necessary 7 crabs is calculated below:

P(X=7)=  {e-2.4*2.47/7!} = 0.0083

b)

The probability that your last pot will be empty is calculated as:

P(X=0)=  {e-2.4*2.40/0!} = 0.0907

NikAS [45]

Answer:

Step-by-step explanation:

Let us represent:

Number of children = x = 59

Number of Adults = y = 166

On a certain hot​ summer's day, 225 people used the public swimming pool.

x + y = 225

x = 225 - y

The daily prices are $1.75 for children and $2.00 for adults. The receipts for admission totaled $435.25.

$1.75 × x + $2.00 × y = $435.25

1.75x + 2y = 435.25

We substitute 225 - y for x

Hence:

1.75(225 - y ) + 2y = 435.25

393.75 - 1.75y + 2y = 435.25

Collect like terms

-1.75y + 2y = 435.25 - 393.75

0.25y = 41.5

y = 41.5/0.25

y = 166 Adults

Note that:

x = 225 - y

x = 225 - 166

x = 59 children

Hence, the number of children is 59 and the number of Adults is 166
