I can do A, I think.
Part A: Marina rented a coat at $285 for 3 days. If as rents the same coat for 6 days she has do pay a total rent of $510. Write an equation in the standard form to represent the total rent (y) that Marina has to pay for renting the coat for x days.
First, find out the base price. If it was $285 for 3 days, then it's: 285/3, which equals $95 per day to rent the coat. Now you can just write the equation. Use the letters x and y to represent the data they want in the equation.
y (total rent) = 95x (x being the number of days). So your equation will be y = 95x, and if someone wanted to solve it they'd just need to give the value of "x"

A farmer who grows genetically engineered corn is experiencing trouble with corn borers. A random check of 5,000 ears revealed t

Ivenika [448]

Answer:

Probability that an ear of corn selected at random will contain no borers is 0.4966.

Step-by-step explanation:

We are given that the distribution of the number of borers per ear approximated the Poisson distribution. The farmer counted 3,500 borers in the 5,000 ears.

Let X = Number of borers per ear

The probability distribution of the Poisson distribution is given by;

$P(X=x) = \frac{e^{-\lambda }\times \lambda^{x} }{x!} ; x = 0,1,2,3,......$

where, $\lambda$ = parameter of this distribution and in our question it is proportion of bores in the total ears = $\frac{3500}{5000}$ = 0.7

SO, X ~ Poisson( $\lambda$ = 0.7)

Now, probability that an ear of corn selected at random will contain no borers is given by = P(X = 0)

P(X = 0) = $\frac{e^{-0.7}\times 0.7^{0} }{0!}$

= $e^{-0.7}$ = 0.4966

Hence, the required probability is 0.4966.
