Answer: Hello, There! Your, Question is A Bit Unclear But I Hope Im right.

<em>12% of 72=8.64 Or your Answer is 16.67</em>

Step-by-step explanation:

If 72 is 100%, so we can write it down as 72=100%.

. We know, that x is 12% of the output value, so we can write it down as x=12%.

5. Now we have two simple equations:

1) 72=100%

2) x=12%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

72/x=100%/12%

Hope this helps you!!

Have a great day!!!

Frank is 4 times as old as Lin. The difference in their ages is equal to Lin’s age plus 8. How old is each?

Minchanka [31]

Let Lin be x years old.
Lin = x
Frank = 4x

<span>The difference in their ages is equal to Lin’s age plus 8
</span>⇒4x - x= x + 8

Solve x:
4x - x= x + 8

Combine like terms:
3x = x + 8

Take away x from both sides:
2x = 8

Divide by 2 on both sides:
x = 4

Lin is 4 years old.
Frank is 4 x 4 = 16 years old.

Answer: Lin is 4 years old and Frank is 16 years old.

A simplified model for the movement of the price of a stock supposes that on each day the stock’s price either moves up 1 unit w

DanielleElmas [232]

Answer:

(a) The probability that after 2 days the stock will be at its original price is

$P_a=2p(1-p)$

(b) The probability that after 3 days the stock’s price will have increased by 1 unit is

$P_b=3p^2(1-p)$

(c) Given that after 3 days the stock’s price has increased by 1 unit, the probability that it went up on the first day is

$P=2/3$

Step-by-step explanation:

(a) What is the probability that after 2 days the stock will be at its original price?

For the price of the stock to be in its original price, there are two ways it can happen:

1) the price increases the first day by one unit and decreases by one unit the second day. The probability of this event is P=p*(1-p).

2) the price decreases the first day by one unit and increases by one unit the second day. The probability of this event is P=(1-p)p.

The probability that after 2 days the stock will be at its original price is the sum of the probability of this two events:

$P=P_1+P_2=p(1-p)+(1-p)p=2p(1-p)$

(b) What is the probability that after 3 days the stock’s price will have increased by 1 unit?

For this event to happen (one unit increase in 3 days), it must have happened 2 increases in price and 1 decrease.

There are 3 possible ways of this to happen:

1) decrease in the first day.

2) decrease in the second day.

3) decrease in the third day.

Each one ot this 3 events has the same probability $P_i=p^2(1-p)$ .

So the probability that after 3 days the stock’s price will have increased by 1 unit is equal to the sum of the probabilities of this events:

$P=P_1+P_2+P_3=3p^2(1-p)$

(c) Given that after 3 days the stock’s price has increased by 1 unit, what is the probability that it went up on the first day?

According to the answer (c), there are 3 events where the price has increase by one unit after 3 days, each one with equal probability $P_i=p^2(1-p)$ .

Of these 3 events, there are 2 that have an increase in the first day. So we can conclude that, if the events have the same probability, the probability of the increase in the first day, given that the price has increased by one unit in 3 days, is P=2/3.
