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]

What is the length help me
kirza4 [7]

Since AM = 2cm and AC = 6cm we can write the following:

AM + AC = 8cm

So, now we only create a fraction demonstration the length from AM to AC:

\frac{2}{8} which can be simplified to \frac{1}{4}

Conclusion/answer:

The length from AM to AC is: \frac{1}{4}



Hope it helped,

Will give brainliest!! Part of me thinks the answer is D but I just want to double check.
Rom4ik [11]

Answer: C) 6.0025

Step-by-step explanation:

The equation for the area of a circle requires the radius, you put in the full diameter. Just divide 4.9 by 2, which gives you 2.45. 2.45 squared is equal to 6.0025 and then slap your pi on to the end of it.
