Answer:

(1/6)^3 = 1/216, these events are independent.

Step-by-step explanation:

What happens in one roll has no effect on the other rolls, so these events are independent. The probility of any roll outcome is 1/6 since there are 6 sides. Since you want to roll a 6 AND a 5 AND a 4 you have to multiply the probabilities.

Answer:

slope=4root5

Step-by-step explanation:

H^2=b^2+ h^2

(8)^ +(4)^

= 64+16

H^ =80

H= ROOT 80

root(4*4*5)

=4root(5)

Oxana [17]

SOLUTION

From the image in the question, we can see that it is a right triangle problem.

And we can use the Pythagoras theorem to solve for the length of cable wire needed.

Pythagoras theorem states that:

$\begin{gathered} \text{hypotenuse}^2=opposite^2+adjacent^2 \\ x^2=4^2+3^2 \end{gathered}$ $\begin{gathered} x^2=16+9 \\ x^2=25 \\ \text{Take the square roots of both sides:} \\ \sqrt[]{x^2}=\sqrt[]{25} \\ x=5ft \end{gathered}$

Final Answer:

A cable of length 5 feet is needed.

$\bf \displaystyle \int \left( 4+\cfrac{5}{t}+\cfrac{10}{t^2} \right)dt\\\\
-----------------------------\\\\
\displaystyle \int 4 \cdot dt+5\int \cfrac{1}{t}\cdot dt+10\int t^{-2}\cdot dt
\implies 
4t+5ln|t|-\cfrac{10}{t}+C$
