Solve for x. 13x - 7 = 136

aniked [119]

Add 7 on both sides to then left side cancels out and you end up with 13x=143 then you divide 13 on both sides and get x=11

There are three highways in the county. the number of daily accidents that occur on these highways are poisson random variables

Romashka-Z-Leto [24]

There is a theorem that we can use to find the expected value of a random variable that is a sum of other random variables as follows.

If $X=X_1 + X_2 + ...+X_k$ , then $E(X)=E(X_1)+E(X_2)+...+E(X_k)$ .

In this case, let X = the number of accidents that will happen on any of those highways today,
$X_1,X_2,X_3$ are the numbers of accidents on each highway, respectively.

Then $X = X_1+X_2+X_3$ .

Since $X_1,X_2,X_3$ are Poisson variates, their expected values are the parameters given, .3, .5 and .7.

So $E(X_1)=.3, E(X_2) = .5, E(X_3) = .7$
Thus, $E(X)=E(X_1)+E(X_2)+E(X_3) = .3 + .5 + .7 = 1.5$

The answer is 1.5.
