The expression to show how to find Milan's age when Raul is 14 is x + 6 = 14.

An expression is simply used to show the relationship between the variables in the data.. Addition, subtraction, multiplication, and division are possible mathematical operations.

Let Milan's age be x

Rauls age = x + 6

Therefore, when Raul is 14, Milan will be:

x + 6 = 14

Collect like terms

x = 14 - 6

x = 8

Milan is 8 years.

The expression is x + 6 = 14

Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis. Multiplication tables are the main use that is obvious.

The repeated addition of one number in relation to another is represented by the multiplication of two numbers. These figures can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times or the other way around.

In addition to addition, subtraction, and division, multiplication is a mathematical operation. The four fundamental arithmetic operations are taught to students in their primary classes.

We have to fill the blank.

We know that,

The metric system's fundamental mass unit is the kilogram. In the past, it has been measured using a variety of sources. It was first calculated based on the weight of 1000 cc of water. Water density varies according to temperature. Furthermore, this reference has been abandoned since the contaminants and solutes in water also provide erroneous results when standardizing the ideal mass of 1 kg.

A gram is described as the 1/1000th of a kilogram in the reference used to define a mass of 1 kg. The maximum density of 1 g/cc was originally used to define it as the mass of 1 cc of water.

The median is the value that separates the upper and lower halves of a data sample, population, or probability distribution in statistics and probability theory. It is sometimes referred to as "the middle" value in a data collection.

Solution:

Firstly we need to arrange the data in ascending order

The predicted quantity of balls in the first bin is (1/n)n.

Considering that,

There are the same number of balls and containers.

If so, then each container must always contain one ball. The probability of each ball landing in the first bin is (1/n)n.

For instance -

Three balls and three bins should be present. Next to each ball, place an A, B, and C. There are numbers 1, 2, and 3 on the containers. Ball A has a 1/3 chance of landing in bin 1. Although there is a 1/3 probability that ball B will drop in bin 1 and a 1/3 chance that ball C will do the same, both outcomes are possible. Therefore, bin 1 should be equal to 1/3 + 1/3 + 1/3. The rationale behind the projected values of bins 2 and 3 is identical.

According to the same logic, bins 2 and 3 should also have expected values of 1.

How probable is it that the first bin will receive all three balls?

In general, (1/n)n, which equals (1/3)3, or 1/3 x 1/3 x 1/3, equals 1/27.

Therefore, (1/n)n would be the expected number of balls in the first bin.

The expected counts for each possible outcome are given by Ei = npi

What is mutually exclusive​ outcomes?

When two events cannot happen simultaneously or at the same time, they are said to be mutually exclusive in probability theory. In other words, discontinuous occurrences are described as being mutually exclusive. The likelihood of two events occurring simultaneously is 0 if they are regarded as disjoint events. Events that do not occur simultaneously are said to be mutually exclusive. When a coin is tossed, for instance, the outcome will either be head or tail, but we cannot get both outcomes.

The expected counts for each possible outcome are given by Ei = npi

Suppose there are n independent trials of an experiment with k > 3 mutually exclusive outcomes,

where pi represents the probability of observing the ith outcome.

The time that has elapsed before the body was found is 1.5 hour

Newton's law of cooling states that the rate of heat loss from a body is inversely related to the temperature difference between the body and its surroundings.

Given:

when time, t = 0, temperature = 98.6 ⁰F

when time, t = 1, temperature = 75⁰

when time,  t = t, temperature = 80⁰

By Newton's method of cooling equation;

T(t) = [tex]T_s (T_0 - T_s)e^{kt[/tex]

T(t) = 70+  28.6[tex]e^{kt[/tex]

Now, At the time of discovery

80 = 70+  28.6[tex]e^{kt[/tex]

10= 28.6[tex]e^{kt[/tex]

Then, 1 hour later( t + 1) we have the second equation;

75= 70 + 28.6[tex]e^{kt[/tex]

28.6[tex]e^{kt[/tex] = 5

Now, divide equation 1  by equation 2;

2= [tex]e^{-k[/tex]

k = -0.693

The time when he dead body was discovered

10= 28.6[tex]e^{kt[/tex]

10= 28.6[tex]e^{-0.693[/tex]

-0.693t = ln (10 /28.6)

Solving a variable equation includes determining which variables' values result in equality. Unknowns are the variables for which the equation must be solved, while equation solutions are the unknown values that satisfy the equality. An equation is a mathematical phrase with two equal sides separated by an equal sign. An equation is 4 + 6 = 10. We can see 4 + 6 on the left side of the equal sign and 10 on the right.

Using Pythagoras's theorem, the relationships of the sides of the right triangle is x² - 21x + 108 = 0.

The value of x in the right triangle is x = 9 or x = 12.

The right angle triangle is a triangle with one of its angles as 90 degrees. The sides of a right angle triangle can be found using Pythagoras's theorem.

Hence,

c² = a² + b²

where

Therefore, the equation to show the relationships between the three sides can be gotten by applying Pythagoras's theorem.

x² + (21 - x)² = 15²

x² + (21 - x)(21 - x) = 225

x² + 441 - 21x - 21x + x² = 225

2x² - 42x + 441 - 225 = 0

2x² - 42x + 216 = 0

divide through by 2

x² - 21x + 108 = 0

Let's find the value of x by factoring.

x² - 21x + 108 = 0

x² - 12x - 9x + 108 = 0

x(x - 12) - 9(x - 12) = 0

(x - 9)(x - 12) = 0
