Well each piece of the whole is what made the whole... so in that case each piece is little 1/4's of the whole....

Tanya [424]

Answer:

$y = x-7$

Step-by-step explanation:

Step 1: Write the equation in point-slope form

Point Slope Form: $y-y_{1}=m\left(x-x_{1}\right)$

Plug in the numbers and solve

$y - (-2) = 1(x - 5)$

$y + 2 = x - 5$

$y + 2 - 2 = x - 5 - 2$

$y = x-7$

Answer: $y = x-7$

Answer:

1.3125

Step-by-step explanation:

Given that our random variable $X$ follows a Poisson distribution $P(X=k)=\frac{\lambda^k e^-^p}{k!} \ \ \ \ \ \ \ \ p=\lambda$

Evaluate the formula at $k=2,3:$

$P(X=2)=0.5\lambda^2e^{-\lambda}\\\\P(X=3)=\frac{1}{6}\lambda^2e^{-\lambda}$

#since

$4P(X=2)=P(X=3);\\\\0.5\lambda^2e^{-\lambda}=4\times\frac{1}{6}\lambda^3e^{-\lambda}\\\\0.5\lambda^2=\frac{2}{3}\lambda^3\\\\0.75=\lambda$

The mean and variance of the Poisson distributed random variable is equal to $\lambda$ :

$\mu=\lambda=0.75\\\sigma ^2=\lambda=0.75$

#By property variance:

$\sigma ^2=V(X)=E(X^2)-(E(X))^2=E(X^2)\\\\E(X^2)=\sigma^2+\mu^2=0.75+0.75^2=1.3125$

The expectation is 1.3125
