A garden has a circular border and a fountain in the center. I measured the distance from one side of the garden to the other, g

Snezhnost [94]

Answer:

The length of the border is approximately 4 feet.

Step-by-step explanation:

Since the garden has a circular border we can apply the formula for the circle's length, which is shown below:

$length = 2*\pi*radius$

Where the radius is half the diameter. The diameter is the distance between two points in the circle going through the center, therefore for this garden the diameter is 1.2 feet and the radius is 0.6 feet. Applying this to the formula gives us:

$length = 2*\pi*0.6\\length = 1.2*\pi\\length = 3.8$

The length of the border is approximately 4 feet.

The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift.

NeX [460]

Answer:

0.674

Step-by-step explanation:

If the random variable X is exponentially distributed and X has an average value of 25 minutes, then its probability density function (PDF) is

$\bf f(x)=\frac{1}{25}e^{-x/25}\;(x\geq 0)$

and its cumulative distribution function (CDF) is

$\bf P(X\leq t)=\int_{0}^{t} f(x)dx=1-e^{-t/25}$

So, the probability that X is less than 28 minutes is

$\bf P(X\leq 28)=1-e^{-28/25}=1-e^{-1.12}=0.674$
