Answer:
Smaller x value = -1 and y = -2.
Larger x value = 1 and y = 2.
Step-by-Step explanation:
x^2 + y^2 = 5
y = 2x
Substitute y = 2x into the first equation:
x^2 + (2x)^2 = 5
x^2 + 4x^2 = 5
5x^2 = 5
x^2 = 1
x = ±1
So y = 2 * ±1 = ±2
The average adult has about 1.2 to 1.5 gallons of blood. So less than 5 gallons.
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:

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

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

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

Then, the expected profit can be calculated as:

Answer:
1/7 divided by 1/98 will give you 14
