What are the similarities and differences between a radius and a diameter?

Mathematics

Ivenika [448]3 years ago

Similarities:

  • They are both line segments.
  • They are both found in circles.
  • Radius is a half of diameter and diameter is twice the radius making them dependent.
  • Their intersection is always contains the center of the circle.
  • Their set intersection equals to radius and their set union equals to diameter.

Differences:

  • Diameter is longer (unless its 0)
  • Diameter touches two different points on the circumference while radius only one point
  • Center angle of diameter is 180° while of radius is 0° or 360°.
  • The Diameter is constructed via line
  • The Radius is constructed via line or ray

Difference would be that is a diameter is double a radius and a radius is half of a diameter.
A similarity would be that they would are within a circle and touch the center of circle

For X a binomial random variable with n=5 and p=1/4, answer the following
mash [69]
Recall that for X\sim\mathrm{Bin}(n,p), i.e. a random variable X following a binomial distribution over n trials and with probability parameter p,

\mathbb P(X=x)=f_X(x)=\begin{cases}\dbinom nx p^x(1-p)^{n-x}&\text{for }x\in\{0,1,\ldots,n\}\\\\0&\text{otherwise}\end{cases}

So you have

\mathbb P(X=2)=\dbinom52\left(\dfrac14\right)^2\left(1-\dfrac34\right)^{5-2}=\dfrac{135}{512}\approx0.26

\mathbb P(2\le X\le4)=\displaystyle\sum_{x=2}^4\mathbb P(X=x)
=\dbinom52\left(\dfrac14\right)^2\left(1-\dfrac14\right)^{5-2}+\dbinom52\left(\dfrac14\right)^3\left(1-\dfrac14\right)^{5-3}+\dbinom52\left(\dfrac14\right)^4\left(1-\dfrac14\right)^{5-4}
=\dfrac{375}{1024}\approx0.37

The expected value of X\sim\mathrm{Bin}(n,p) is simply np, while the standard deviation is \sqrt{np(1-p)}. In this case, they are \dfrac54=1.25 and \sqrt{\dfrac{15}{16}}\approx0.97, respectively.

Answer:

the answer is not correct

there is a sign error under the radical

it should be 3^2 - 4(-8)(2) = sqrt(73) not sqrt(55i)
