Answer:

\dfrac{1}{12}

Step-by-step explanation:

All possible outcomes:

\begin{array}{cccccc}1,1&1,2&1,3&1,4&1,5&1,6\\2,1&2,2&2,3&2,4&2,5&2,6\\3,1&3,2&3,3&3,4&3,5&3,6\\4,1&4,2&4,3&4,4&4,5&4,6\\5,1&5,2&5,3&5,4&5,5&5,6\\6,1&6,2&6,3&6,4&6,5&6,6\end{array}

Here, the first number is the number on the 1st die and the second number is the number on the 2nd die.

There are 36 possible outcomes.

A total of 4 give outcomes:

1,3\\2,2\\3,1

So, there are 3 favorable outcomes.

The probability of getting a total of 4 is

\dfrac{3}{36}=\dfrac{1}{12}

mafiozo [28]
We are given with the initial population and is asked for the final population after n years. in this case, we use the formula P(n) = Po* (1 + r)^n where r is the rate of growth. 1)  P(n) = Po* (1 + r)^n    P(n) = 8600* (1 + 0.03)^3    P(n) = 9397 people
2)  P(n) = Po* (1 + r)^n    P(n) = 1500* (1 + 0.02)^4    P(n) = 1624 deers

The dimensions of Sara's apartment are22 1/2 feet by 25 feet. In the scale drawing below,1 1/2 inches is equivalent to 15 feet.
expeople1 [14]

Answer:

Step-by-step explanation:

Given:

The scale 1 1/2 (\frac{3}{2}) inches = 15 feet

<=>  1 inch = \frac{15 feet}{\frac{3}{2} } = 10 feet.

<=> 1 feet = \frac{1}{10} inch

The dimensions of Sara's apartment are 22 1/2  (\frac{45}{2}) feet by 25 feet, so the new dimensions of Sara's apartment by inches are:

  • (\frac{45}{2}) feet = \frac{45}{2} * \frac{1}{10} = \frac{9}{4} inches
  • 25 feet = 25*\frac{1}{10} = \frac{5}{2} inches

Hope it will find you well.
