Erika needs to purchase 13 boxes, although she will have 3 more pencils than needed, 12 boxes would not be enough, in other words she will have 3 extra, but that is the only way that she will acquire the required amount.

A market survey shows that half the owners of Sorey State Boogie Boards became disenchanted with the product and switched to C&a
OlgaM077 [116]

Answer:

\left[\begin{array}{ccc}\dfrac{1}{2} &\dfrac{1}{2}\\\\\dfrac{1}{4}&\dfrac{3}{4}\end{array}\right]

Step-by-step explanation:

Let 1 = Sorey State, and 2 = C&T

Half the owners of Sorey State Boogie Boards became disenchanted with the product and switched to C&T Super Professional Boards the next surf season.

  • This means half moved from State 1 to State 2.

Three quarters of the C&T Boogie Board users remained loyal to C&T, while the rest switched to Sorey State.

  • The rest (1-\frac{3}{4}= \frac{1}{4}) moved from State 2 to State 1.

The Markov Transition Matrix is presented below:

\left\begin{array}{ccc}\\\\\\$Sorey State&1\\\\C\&T&2\end{array}\right\left[\begin{array}{ccc}$Sorey State&C\&T\\1&2\\------&------\\\dfrac{1}{2} &\dfrac{1}{2}\\\\\dfrac{1}{4}&\dfrac{3}{4}\end{array}\right]

The above is presented for clarity sake. The transition matrix is:

\left[\begin{array}{ccc}\dfrac{1}{2} &\dfrac{1}{2}\\\\\dfrac{1}{4}&\dfrac{3}{4}\end{array}\right]

The scale on map is 2 cm =25 miles dave measured the distance to the next town at 5 cm
Slav-nsk [51]

Answer:

Proportion states that the two ratios or fractions are equal

Given the statement:

The scale on map is 2 cm =25 miles.

Dave measured the distance to the next town at 5 cm.

We have to find the what miles away is the next town.

Let x be the distance in miles away is the next town.

By definition of proportion:

\frac{2}{25} = \frac{5}{x}

By cross multiply we get;

2x = 5 \times 25

Simplify:

2x = 125

Divide both sides by 2 we get;

x = 6.25 miles

Therefore, 6.25 miles away is the next town.
