Well, Complementary events are two outcomes of an event that are the only two possible outcomes.<span>
So, getting a head or a tail when tossing a coin is one of them because there are only 2 possible outcomes. Heads or tails. </span>

Examine this right triangle. A right triangle has a side length of 16 meters and hypotenuse of 20 meters. Which equation can be

Sergeu [11.5K]

The equation can be used to find the missing leg in the triangle $20^{2} = 16^{2} +a^{2}$ .

<h3>What is the right triangle?</h3>

A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse.

It is given that a right triangle has a side length of 16 meters and a hypotenuse of 20 meters.

From a Pythagoras theorem

$b^{2} = c^{2} +a^{2} \\20^{2} = 16^{2} +a^{2}\\20^{2}-16^{2} =a^{2}\\a^{2} = 20^{2}-16^{2} \\$

Thus, the equation can be used to find the missing leg in the triangle $20^{2}-16^{2} =a^{2}$ .

A new online music service has a collection of 1,500 songs. It expects to triple the number of songs each year for the next few

Rzqust [24]

Answer: y = (3^(x-1))*1500

Step-by-step explanation:

We want the relationship

y = f(x)

where y is the number of songs, and x is the number of years.

We know that in the first year, x = 1, the site has 1,500 songs.

The next year, x = 2, the number of songs is tripled, then we will have:

1,500*3 = 4500 songs.

The next year, x = 3, we will have: 3*(3*1500) = (3^2)*1500.

when x = 4, the number is tripled again:

3*(3^2)*1500 = (3^3)*1500

We already can see the pattern, for the year x, the site will have:

y = (3^(x-1))*1500 songs.

This is the equation we are looking for.

Why is 5 mililon greater than 152000

Masja [62]

5 million is greater than 152000 because 5 million = 5,000,000 and that is larger than 152000 (only 152 thousand; 5 million is 5000 thousands)

Does choosing a blue marble represent the complement event of choosing a red marble? Explain.

Arada [10]

Answer:

Below is the sample response

Step-by-step explanation:

The complementary event for choosing a red marble is choosing a blue or purple. The total number of marbles is 5. The probability of choosing a red marble is 1/5, and the complement would be 4/5. That is not the same as choosing a blue marble.
