The perimeter of a rectangular field is 372 yards. If the width of the field is 87 yards, what is its length?__yards
worty [1.4K]

ANSWER

The length of the rectangular field is 99 yards

EXPLANATION

Given information

The perimeter of a rectangle field is 372 yards

The width of the field is 87 yards

To find the length of the rectangular field, follow the steps below

Step 1: Write the formula for finding the perimeter of a rectangular field

\begin{gathered} \text{ The perimeter of a rectangular field = 2\lparen l + w\rparen} \\ \text{ where l =length, and w = width} \end{gathered}

Step 2: Substitute the given data into the formula in step 1

\begin{gathered} \text{ Perimeter = 2 \lparen l + w\rparen} \\ \text{ Perimeter = 372 yards} \\ \text{ width = 87 yards} \\ \text{  372 = 2\lparen l + 87\rparen} \\ \text{ Divide both sides by 2} \\ \text{ }\frac{372}{2}\text{ = }\frac{2}{2}(l\text{ + 87\rparen} \\ 186\text{ = l + 87} \\ \text{  subtract 87 from each sides of the equation} \\ \text{ 186 - 87 = l + 87 - 87} \\ \text{  99 = l} \\ l\text{ = 99 yards} \end{gathered}

Hence, the length of the rectangular field is 99 yards

Assume a Poisson random variable has a mean of 5 successes over a 125-minute period.
goldenfox [79]

Answer:

a

\mu  =  25

b

\lambda  =0.04

c

P(X > 65 ) =0.0742  

Step-by-step explanation:

From the question we are told that

  The  number of success is  n =  5

   The time duration is  N  =  125 minutes

   

Generally the mean of the random variable is mathematically represented as

       \mu  =  \frac{N}{n}

=>    \mu  =  \frac{125}{5}

=>    \mu  =  25

Generally the rate parameter is mathematically represented as

      \lambda  =  \frac{1}{\mu}

=>   \lambda  =  \frac{1}{25}

=>   \lambda  =0.04

Generally the cumulative distribution function for exponential distribution function is  

   F(x) = \left \{0 \ \ \ \ \ \  x \le  0}} \atop {1 -e^{-\lambda t }\   x>0}} \right.

Generally the probability that the time to success will be more than 63 minutes is mathematically represented as

 P(X > 65 ) =  1 - P(X \le 65)

Here

    P(X \le 65) =  1 -e^{-65 *  \lambda }  

=>       P(X \le 65) =  1 -e^{-65 *  0.04 }    

=>       P(X \le 65) = 0.92573    

So

     P(X > 65 ) =  1 - 0.92573  

     P(X > 65 ) =0.0742
