A zoo keeper wants to fence a rectangular habitat for goats. The length of the habitat should be at least 80 feet and the perime

zimovet [89]

Answer:

Step-by-step explanation:

Let x ft be the length of the fence and y ft be the width of the fence.

1. The length of the habitat should be at least 80 feet, then

2. The perimeter of the habitat should be no more than 300 feet. The perimeter of the fences 2x+2y ft, then

3. The system of inequalities that represent the model is

The graph of these inequalities is attached.

Two possible solutions are

1. x=100 ft, y=20 ft (100≥80 and 2·100+2·20=240≤300);

2. x=110 ft, y=30 ft (110≥80 and 2·110+2·30=280≤300).

The owners of a large pet store have determined that 65\ee, percent of their customers own dogs. They select 151515 customers at

crimeas [40]

Answer:

D is a binomial random variable with $p = 0.65, n = 15$

Step-by-step explanation:

For each customer, there are only two possible outcomes. Either they have dogs, or they do not. The probability of a customer having a dog is independent of any other customer. This means that D is a binomial random variable.

Binomial probability distribution

Probability of exactly x successes on n repeated trials, with p probability.

65% of the customers have dogs:

This means that $p = 0.65$

15 customers:

This means that $n = 15$

What type of variable is D?

D is a binomial random variable with $p = 0.65, n = 15$

Determine how many terms of the following convergent series must be summed to be sure that the remainder is less than 10 Supersc

algol13

Answer:

You need to sum at least 5000 terms

Step-by-step explanation:

Remember what the estimation theorem for alternating series says.

Given a series

$s = \sum\limits_{n=0}^{\infty} (-1)^n a_n$

An upper bound for the error of the series $R_n$ is $a_{n+1}$ so

$R_n = |s-s_n| \leq a_{n+1}$

For this case you want

$\frac{1}{2n+1} \leq \frac{1}{10^4}\\10^4 \leq 2n+1\\(10^4-1 )/2 \leq n$

$(10^4-1 )/2$ is approximately 5000. So you must sum at least 5000 terms.
