An investment analyst has tracked a certain bluechip stock for the past six months and found that on any given day, it either go

anastassius [24]

Answer:

0.2109 or 21.09%

Step-by-step explanation:

In order to maintain the same price after two days, the stock must go up (U) on two days and go down (D) on two days, the sample space for this event is:

S={UUDD, UDUD, UDDU, DDUU, DUDU, DUUD}

There are 6 equally likely possible outcomes. The probability that the price of the stock will be the same as it is today is:

$P =6* (0.25*0.25*0.75*0.75)\\P=0.2109=21.09\%$

The probability is 0.2109 or 21.09%.

For a given set of rectangles, the length is inversely proportional to the width. In one of these rectangles, the length is 12 a

RSB [31]

Answer:

The width is 8 units

Step-by-step explanation:

This is a variation problem we are to work with.

Length is inversely proportional to width, let length be l and width be w

modeling the statement mathematically, we have lw = k where k is the proportionality constant

Now let’s get k from l = 12 and w = 6

k = 12 * 6 = 72

Now for the second rectangle also;

lw = k given l = 9

9w = 72

w = 72/9

w = 8
