Can someone please explain composite events to me in layman's terms?

Answers

Step-by-step explanation:

A simple event is one that can only happen in one way - in other words, it has a single outcome. If we consider our previous example of tossing a coin: we get one outcome that is a head or a tail. A compound event is more complex than a simple event, as it involves the probability of more than one outcome.

what is the ratio of water around in swamps to the total quantity of fresh water on the surface?

Answers

Answer:

Of the liquid surface fresh water, 87% is contained in lakes, 11% in swamps, and only 2% in rivers.

Step-by-step explanation:

The distribution of water on the Earth’s surface is extremely uneven. Only 3% of water on the surface is fresh; the remaining 97% resides in the ocean. Of freshwater, 69% resides in glaciers, 30% underground, and less than 1% is located in lakes, rivers, and swamps. Looked at another way, only one percent of the water on the Earth’s surface is usable by humans, and 99% of the usable quantity is situated underground.

3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.11

Rain and seasonal flooding cause water levels to fluctuate. In the wet soil, water-tolerant vegetation grows and helps maintain a moist, swampy condition. In many freshwater swamps in the southeastern United States, cypress and tupelo trees grow. ... Alligators, frogs, and many other animals live in these swamps.

Elena is programming a video game. She needs to simulate the power-up that the player gets when they reach a certain level. The computer can run a program to return a random integer between 1 and 100. Elena wants the best power-up to be rewarded 15% of the time. She could use the computer to simulate the player getting the best power-up at least 2 out of 3 times.

Which of the following matches the results to get the best power-up at least 2 out of 3 times.

1 Elena could have the computer generate 3 random integers between 1 and 100. If at least 1 of the numbers are between 1 and 15, then the player got the best power-up at least twice.

2 Elena could have the computer generate 3 random integers between 1 and 100. If at least 2 of the numbers are between 1 and 15, then the player got the best power-up at least twice.

3 Elena could have the computer generate 3 random integers between 1 and 100. If at least 2 of the numbers are between 1 and 30, then the player got the best power-up at least twice.

k k k

2.1 Subtracting a whole from a fraction

2 2 • k

2.2 Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

——————————— = ——————

Simplify 2/k

3 2 (1-2k)

1 k

7.1 Subtracting a whole from a fraction

3 + 2 • k 2k + 3

————————— = ——————

k k

8.1 Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

2 2 • k

2 = — = —————

1 k

9.1 Pull out like factors :

2 - 2k = -2 • (k - 1)

10.1 When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

-2•(k-1)

———————— • k = 0 • k

Now, on the left hand side, the k cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

-2 • (k-1) = 0

Equations which are never true:

10.2 Solve : -2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation:

10.3 Solve : k-1 = 0

Add 1 to both sides of the equation :

k = 1

Step-by-step explanation:

Equations are expressions separated by an equal sign. The value of k that will make the equation true is -1

Equations and expressions

Given the equation expressed as

5−k+12=16

We need to find the value of "k" that will make the equation equal

Given

5−k+12=16

Collect the like terms

17 - k = 16

Subtract 17 from both sides

17 - k - 17 = 16 - 17
k = 16 - 17
k = -1

Hence the value of k that will make the equation true is -1

Answer:

this is irregular shape it has four vertix and two faces

The number of vertices and faces this shape have is 4 and 4.

What are vertices, faces and edges?

Faces are planar mathematical objects. Like a triangle, a rectangle etc. Edges are those line segments, which are on the edge of the faces (of some object considered).

Vertices are points of intersections of different edges.

We are given that;

The figure

Now,

Number of vertices= 3+1

Number of faces= 3+1

Therefore, by vertices the answer will be 4 and 4.

Step-by-step explanation:

Supplementary angles are 2 angles that adds up to 180°

Another words,

(12x + 19) + (22x - 9) = 180°

Now we solve for x by combining like terms:

34x + 10 = 180°

Subtract 10 on both sides:

34x = 170°

Divide 34 on both sides:

x = 5

i know its 24 but can someone please explain it to me?

Answers

you have to first do parentheses so we start in there: 5^2= 25 so 25-10= 15, we next move on to exponents (which is also why we did that first in the parentheses btw) so 2^3= 8, now we’re gonna go in order since it’s all multiplication and division: 15/5=3, then 3x8=24!

Ok! So because we have to use the order of operations you have to start inside the parentheses 5^2=25 then 25-10=15 next you have to do you second set of exponents outside the parentheses 2^3= 8 now you have the equation now u just solve left to right
