Dependent events: The likelihood of one event happening influences the likelihood of the other event happening.

When the result of one event affects the result of another, two events are said to be dependent events.

The likelihood of two connected events is the sum of the probabilities of the occurrences X and Y that happen after X.

The likelihood of one event does influence the likelihood of the other happening.

For instance, the likelihood of drawing another King decreases if you remove a King from a deck of cards without replacing it.

A 22-inch piece of steel is divided into three parts, the length of 1st 2nd and 3rd piece are 3 inch,6 inch and 13 inch.

Given that,

A 22-inch piece of steel is divided into three parts, the second of which is twice as long as the first and the third of which is one inch longer than the first.

We have to find the parts' lengths.

Let us take, the length of the first piece is x inch.

Then the length of the second piece is 2x.

Then the length of the third piece is 4x + 1 inch.

We know total length of the steel is 22 inch.

We can write as,

x + 2x + 4x + 1 = 22

7x = 21

x = 3.

Then, the length of the first piece is 3 inch.

Then the length of the second piece is 2×3=6 inch.

Then the length of the third piece is 4×3 + 1=12+1=13 inch.

Therefore, the length of 1st 2nd and 3rd piece are 3 inch,6inch and 13 inch.

Answer:

193 is it I'm not lying

Step-by-step explanation:

The larger number is 33 and the smaller number is 17.

Let the larger number be x

Then, the smaller number will be x-16

According to the question,

Larger number + smaller number = 50

So,

x+(x-16) = 50

2x = 50+16

2x = 66

x = 66÷2

x = 33

Hence,

Larger number = x = 33

Smaller number = x-16 = 33-16 = 17

Answer:

  x -3y -3z = 0

Step-by-step explanation:

You want to write "City A has three times as many people as cities B and C combined" as an equation in standard form, letting x, y, z, w represent the populations of cities A, B, C, D, respectively.

The populations of cites B and C combined can be expressed by ...

  y +z

Three times the combined population is then ...

  3(y +z)

This is equal to the population of city A, so we can write ...

  x = 3(y +z)

This equation is in standard form when all of the variable terms are on one side of the equal sign, and the expression is simplified.

  x -3(y +z) = 0 . . . . . . . subtract the right side expression

  x -3y -3z = 0 . . . . . . . eliminate parentheses; standard form

The change between the morning and afternoon temperature is 2.7.

It should be noted that temperature simply means the degree of hotness as well as the coldness that is in a particular body

In this case, the temperature was -2 1/2 in the morning . by the afternoon the temperature was 0.2.

The change between the temperature will be:

= 0.2 - (- 2 1/2)

= 0.2 + 2.5

= 2.7

In the metric system, centimeters per minute (cpm) represents speed or velocity. It counts the centimeters that are covered in a minute.

65 mi/hr to 174346 centimeters per minute.

$1 mi/h = 2682.2346355307 cm/ min.

65 × 2682.2346355307 cm/min = 174345.2513095 Centimeters Per Minute.

Always check the results; rounding errors may occur.

The base unit of [speed] (meters per second), 1 Miles Per Hour (mi/h) exists equivalent to

0.44704 meters-per-second,

while 1 Centimeters Per Minute (cm/min) = 0.000166667 meters-per-second.

65 Miles Per Hour to common speed units

65 mi/ h = 65 miles per hour (mi/h)

65 mi/h = 1.0833333333333 miles per minute (mi/m)

65 mi/h = 174346 centimeters per minute

Therefore, the correct answer is 174346 centimeters per minute.

Explanation:

Total number of students = 28

75% of 28 = 75% × 28

First I will define what prime factor means

Prime factors of 42 are the factors of 42 that are prime

Prime numbers are those numbers that have two factors; 1 and itself

Factors of 42 are those numbers that can go into 42 without remainder

So let's list out the factors of 42, they are;

Factors of 42 = 1, 2, 3, 6, 7, 14, 21 and 42

Now among these factors, we will list out the ones that are prime, they are the prime factors

That is;

Prime factors of 42 = 2, 3, and 7

To express 42 as a product of it's prime factors, we have 2 ways of doing this

The first method is; To keep dividing 42 by the smallest prime factors

42 = 2 x 3 x 7

The second method is;

Therefore, the prime factorization of 42 = 2 x 3 x 7

The prime factorization of 42 is 2 × 3 × 7.

The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42.

The positive pair factors of 42 are (1, 42), (2, 21), (3, 14), and (6, 7).

The negative pair factors of 42 are (-1, -42), (-2, -21), (-3, -14), and (-6, -7).

The 42 factors that are prime are known as the prime factors of 42.

Prime numbers are those with just themselves and factor 1 as their factors.

The numbers that can round to 42 without leaving a remainder are known as 42 factors. Let's enumerate the 42 factors, which are as follows:

The value of absolute inequality will be given by 0.002 ≥ |x-3|.

Inequality may be defined as the expression which shows unequal behavior between two entities while absolute inequality expression includes inequality along with an absolute value. For example, |x| > 3, |x| <3, |x| ≤3 or |x| ≥3. Now, let us assume the length of the part in the question as x. Since, the desired length is given as 3mm and also the parts are within 0.002 mm of the desired specifications.

Therefore, the maximum length of the part can be = 3 + 0.002

and the minimum length of the part can be = 3 - 0.002

Therefore, we can write the inequality as

3 - 0.002 ≤ x ≤ 3 + 0.002

⇒ 3 - 0.002 ≤ x and x ≤ 3 + 0.002

⇒ -0.002 ≤ x-3 and x-3 ≤ 0.002

⇒ 0.002 ≥ -(x-3) and x-3 ≤ 0.002 (Because a > b ⇒ -a<-b)

⇒ 0.002 ≥ | x - 3 |

Thus, the required absolute inequality is 0.002 ≥ |x-3|.

Similar triangles are triangles that have the same shape, but their sizes may vary. All equilateral triangles and squares of any side length are examples of similar objects. In other words, if two triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.

The solution for the equations x = 1 and y = 3

A system of linear equations is a collection of at least two linear equations.

In this case, the system of equations is given as

x + y=4

-x + y = 2

Add the equations

So, we have

2y = 6

Divide both sides by 2

y = 3

Substitute y = 3 in x + y = 4

x + 3 = 4
