Answer:

150

Step-by-step explanation:

A sample of metal has a mass of 3,600 grams. The sample is in the

shape of a rectangular prism that has dimensions of 2 centimeters by

3 centimeters by 4 centimeters. What is the density of the sample?

so you would times 3*4*2=24 then you would do 3,600/24=150

Answer:

$- 3x + 6 = 21$

$- 3x = 21 - 6$

$- 3x = 18$

$- 3x \div - 3 = 18 \div - 3$

$x = - 6$

$- 3x + 6 < 21$

$- 3x < 21 + 6$

$- 3x < 27$

$- 3x \div - 3 < 27 \div - 3$

$x > - 9$

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.
