An engineering professor acquires a new computer once every 2 years. the professor can choose from three models: m1, m1, and m3.

if the present model is m1, the next model can be m2 with probability .2, or m3 with probability .15. if the present model is m2, the probabilities of switching to m1 and m3 are .6 and .25, respectively. and, if the present model is m3, then the probabilities of purchasing m1 and m2 are .5 and .1, respectively. represent the situation as a markov chain.

A car travels 21 km in 16 minutes. What is its average speed in km/h?
bekas [8.4K]

Answer:

78.6km/h

Step-by-step explanation:

<em><u>Speed=distance÷time</u></em>

<u>distance</u>=21km

<u>time</u>=16 minutes<u>(convert into hour by dividing it</u> <u>with 60)</u>

=16÷60=0.267

Speed=21÷0.267=78.65km/h

speed =  \frac{distance }{time}

speed =  \frac{21}{0.267}  = 78.6km(h

I NEED HELP PLEASE, THANKS

First, find the scale factor.

8.4 / 7 = 1.2

9 / 7.5 = 1.2

7.2 / 6 = 1.2

Since both solids are different sizes, the solids aren't congruent.

The size ratio for all the sides are:

8.4:7

9:7.5

7.2:6

Since the scale factor isn't 1:1 this also proves that the solids are NOT congruent.

Since both solids are the same kind of shape and have an identical scale factor, the solids are similar.

Best of Luck!
