A man buys a racehorse for $20,000 and enters it in two races. He plans to sell the horse afterward, hoping to make a profit. If

victus00 [196]

Answer:

The expected profit is $10,600.

Step-by-step explanation:

The expected profit can be calculated as the sum of the possible outcomes weighted by their probability of occurrence.

In this case, there are four possible outcomes:

1) The horse win both races. The value of the horse will be $100k-$20k=$80k.

The probability of this outcome is:

$P(ww)=P(w1)*P(w2)=0.2*0.3=0.06$

2) The horse win the first race, but lose the second one. The value will be $50k-$20k=$30k.

The probability is:

$P(wl)=P(w1)*(1-P(w2))=0.2*(1-0.3)=0.2*0.7=0.14$

3) The horse lose the first race, but win the second one. The value will be $50k-$20k=$30k.

The probability is:

$P(lw)=(1-P(w1))*P(w2)=(1-0.2)*0.3=0.8*0.3=0.24$

4) The horse lose both races. The value will be $10k-$20k=-$10k.

The probability is:

$P(lw)=(1-P(w1))*(1-P(w2))=(1-0.2)*(1-0.3)=0.8*0.7=0.56$

Then, the expected profit can be calculated as:

$E(x)=\sum\limits^4_{i=1} {p_ix_i}\\\\E(x)=0.06*80,000+0.14*30,000+0.24*30,000+0.56*(-10,000)\\\\E(x)=4,800+4.200+7,200-5,600=10,600$

The path of a race will be drawn on a coordinate grid like the one shown below. The starting point of the race will be at (−5.4,

k0ka [10]

There are 4 quadrants in a coordinate plane

The starting point is in the second quadrant, while the finishing point is in the fourth quadrant.
The starting point is a reflection of the checkpoint across the y-axis

Part A

The points are given as:

$Start = (-5.4,3)$

$Finish = (3,-5.4)$

For the starting point, the x-coordinate is negative, while the y-coordinate is positive.

This implies that the starting point is in the second quadrant

For the finishing point, the x-coordinate is positive, while the y-coordinate is negative.

This implies that the finishing point is in the fourth quadrant

Part B

The checking point is given as:

$Checking = (5.4,3)$

The starting point is given as:

$Start = (-5.4,3)$

Notice that the y-coordinate of both points are the same, but the x-coordinates are negated.

This means that the starting point is a reflection of the checkpoint across the y-axis, and vice versa

Is 2 between 1.3 and 1.4?how do you know? What it is give me answers

viva [34]

Answer:

Yes

Step-by-step explanation:

Find the square root of two between the two numbers

The square root of 2 adds up to the number 1.4

Square root is multiplied twice x2, y2

If you check the answer you'll get that 1.4 is the square root of 2

Multiple 1.4x1.4

You will get 1.96 and since it's a six in the ones spot you'll round up to 2
