Answer:

To find the area of a composite figure or other irregular-shaped figure, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.

Write the equation for the following table: X. Y. 0 3 1 7 2 11 3 15

Vanyuwa [196]

Answer:

$y = 4x + 3$

Step-by-step explanation:

The equation of the table of values given can be written as $y = 4x + 3$ .

When x = 0,

$y = 4(0) + 3$

$y = 0 + 3 = 3$ this corresponds with what we have in the table above.

Let's try another.

When x = 2,

$y = 4(2) + 3$

$y = 8 + 3$

$y = 11$

This also corresponds with what we have in the table.

Therefore, the equation of the table given is $y = 4x + 3$ .

kykrilka [37]

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
