Answer:

50% of a number means that we are taking half of a number. Since 11 is 50% of a number that means that we need to multiply 11 by 2 to get the original number. When we multiply 11 by 2 we get 22 and that is closest to option A which is 20.

Answer: Option A, $20$

Answer:

The correct answer is C.

Step-by-step explanation:

In the equation of a circle, if the variable $x$ and $y$ are added or subtracted by any number before being squared, the entire circle with be translated in the opposite amount that was added or subtracted to the circle. For example, $(x-8)^2 + (y-8)^2$ shifts the center 8 to the right and up of the origin, $(x+1)^2+(y+4)^2$ shifts the center 1 to the left and 4 down of the origin. Since the circle represented in the graph is centered directly on the origin, that means the equation will have $x^2+y^2$ , which helps you eliminate choices A and C. For the equation of a circle, the radius is the value of the constant on the right side of the equal sign taken to its square root. Since the radius of this circle is 8, that means the constant at the right side of the circle would be 64 or $8^2$ , so the correct answer would be choice C: $x^2+y^2=8^2$ .

<h3>What is probability?</h3>

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

We have:

A coin toss is used to determine which team will receive the ball at the beginning of a football game.

The Cougars always choose tails in the toss.

There will total of 8 cases and in 8 cases there will be three cases in which exactly two heads will come so,

3:8

The cases = {TTT, TTH, THT, HTT, HHT, HTH, HHT, HHH}

Thus, the odds in favor of the Cougars losing the toss in exactly two of three games is 3:8 option second is correct.

An example of an asset-producing debt

erastovalidia [21]

<span>For example, education debt is a fact of life for many of us but we should view it as an investment in our future. We’d like to think it will provide us with an opportunity to increase our future income, so that makes it good debt. Debt for an unaffordable expensive car would be considered bad debt since it is an unnecessary expense that provides no income and depreciates in value. Debt for something that depreciates and provides no income would certainly be considered bad debt. An education is an investment that appreciates in value by increasing future income potential... the car is a depreciating expense that will provide no income and will rapidly depreciate in value (uses up income instead of providing income). The expensive car may be more fun to have, but the education will be the best investment.</span>
