The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift.
garik1379 [7]

Answer:

The probability that X is less than 32 minutes is 0.736.

Step-by-step explanation:

Given : The random variable X is exponentially distributed, where X represents the time it takes for a person to choose a birthday gift. If X has an average value of 24 minutes.

To find : What is the probability that X is less than 32 minutes?

Solution :

If X has an average value of 24 minutes.

i.e. \lambda=24

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

The exponentially function is \frac{1}{\lambda}e^{-\frac{x}{\lambda}}

The function form according to question is

f(x)=\{\frac{1}{24}e^{-\frac{x}{24}}, x>0\}

The probability that X is less than 32 minutes is

P[x

P[x

P[x

Therefore, the probability that X is less than 32 minutes is 0.736.

Please help!!!! ASAP giving brainiest
mariarad [96]

Answer:

JK=2.25\ units

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

so

\frac{JK}{ST}=\frac{KL}{TU}

substitute the given value and solve for JK

\frac{JK}{1.5}=\frac{6}{4}

JK=(1.5)\frac{6}{4}

JK=2.25\ units

irina1246 [14]

Answer: 8cm

Step-by-step explanation:

V=\pi r^2h

Solve for h;

h=\frac{V}{\pi r^2}

h=\frac{400cm^3}{(3.14)(4cm)^2}

h=7.96\\h=8
