What is the expectation for a binomial distribution with p = 0.5 and n = 8?

Mathematics

Natasha2012 [34]3 years ago
8 0

Answer: 4

Step-by-step explanation:

Given the following :

P = probability of success = 0.5

n = number of trials = 8

The expected value of a binomial distribution with probability of success P and number of trials n is defined by:

E(n, p) = n * p

Therefore, expected value when P = 0.5 and n = 8

E(8, 0.5) = 8 × 0.5

= 4

The expected value of the binomial distribution is 4

A small 17 kilogram canoe is floating downriver at a speed of 2 m/s. What is the
RideAnS [48]
<h2>Hello!</h2>

The answer is:

Answer: 34

Units: Joules

KE=34J

<h2>Why?</h2>

The kinetic energy is the work needed to accelerate an object to a determined speed.

The kinetic energy can be calculated using the following equation:

KE=\frac{1}{2}mv^{2}

Where,

m, is the mass of the object.

v, is the speed of the object.

So, we are given the information:

mass=17kg\\\\v=\frac{2m}{s}

Then, substituting and calculating we have:

KE=\frac{1}{2}mv^{2}

KE=\frac{1}{2}*17kg*(\frac{2m}{s})^{2}

KE=8.5kg*(\frac{4m^{2}}{s^{2}})

KE=34\frac{kg.m^{2}}{s^{2}}=34J

Have a nice day!

A building is 50 feet tall and casts a 25 foot shadow. If Mark is 6 feet tall, how long would
trasher [3.6K]

Answer:

Mark's shadow would be 3 feet.

Step-by-step explanation:

If a building is 50 feet tall and casts a 25 foot shadow, then the shadow of an object is <u>1/2</u> the length of the actual object.

This can be supported by the division problem:

50 ÷ 2 = 25

If Mark is 6 feet tall, then we need to <em><u>divide</u></em> 6 by 2 in order to find the length of the shadow.

6 ÷ 2 = 3

Therefore, Mark's shadow would be 3 feet.

Hope this helps! :D
