The decimal system is a positional notation system, which means that the value of a digit in a number depends on its position in the number.

In the decimal system, each digit can take on one of ten possible values (0, 1, 2, 3, 4, 5, 6, 7, 8, or 9), and the value of a number is determined by multiplying each digit by its corresponding power of ten and then summing up the products.

For example, the number 123 can be written as [tex]1 x 10^2 + 2 x 10^1 + 3 x 10^0[/tex], where the exponent on the 10 indicates the position of the digit in the number. The left-most digit (1) is in the hundreds place, the next digit (2) is in the tens place, and the right-most digit (3) is in the ones place.

This positional notation system allows us to easily compare numbers by starting at the left-most non-zero place, because the value of each digit is determined by its position relative to the other digits in the number. The left-most digit represents the largest power of 10, and thus has the greatest impact on the overall value of the number. By comparing the left-most non-zero digits of two numbers, we can quickly determine which number is larger. If the left-most non-zero digits are the same, we can move on to the next digit to the right and continue the comparison until we find a difference.

This is why we use the left-to-right ordering of digits to compare numbers in the decimal system. It allows us to quickly determine the relative size of numbers, even when dealing with large or complex numbers.

At 38 meters into the pool, the water is 7.6 meters deep. Water depth is the distance in feet between the ocean's surface and bottom, as determined by mean lower low water.

Ocean depth is most frequently and quickly measured using sound. Sonar, which stands for sound navigation and range, is a technique that allows ships to map the topography of the ocean below. The instrument uses sound waves to send to the ocean's bottom and time how long it takes for an echo to come back. The straightforward formula "d/2 = vt" is used to determine the depth "d" because the speed of sound in water is known.

height-1 = 10

height-2 = 38

depth-1=2 m

depth-2 = ?

depth-2 = (height 2* depth 1)/height 1

depth-2 = ( 38*2)/10

An outlier in a data set can significantly affect the value of the mean but not the median because the mean is calculated by adding up all the values and dividing by the total number of values, while the median is the middle value of a set of data when it is arranged in numerical order. Outliers can greatly influence the mean because they can greatly increase or decrease the sum of all the values, which changes the average. However, outliers do not significantly affect the median because the median only depends on the middle value of the data set, and not the total sum of all the values.

The solution for the given expression b = √ -1 -2b is b = -1.

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax^2 + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. First, there must be a term other than zero in the coefficient of x^2 (a not equal 0) for an equation to be a quadratic equation.

The expression is:

b = √ -1 -2b

Take square on both sides of the equation. The square negates the square root and we have the following expression:

b² = - 1 - 2b

b² + 2b + 1 = 0

The quadratic formula is given as:

x = - b ± √b² - 4ac ÷ 2a

Substituting the value of b = 2, a = 1 and c = 1:

x = -2 ± √4 - 4(1)(1) ÷ 2(1)

x = -2 ÷ 2

x = -1

Hence, the solution for the given expression b = √ -1 -2b is b = -1.

Answer:

The radius can be shown in 2 different forms

Fraction Form

[tex]r=\sqrt[3]{\frac{27}{\pi}}[/tex]

Decimal Form

[tex]r=2.05[/tex]

Step-by-step explanation:

The formula for the volume of the sphere is

[tex]V=\frac{4}{3}\pi r^3[/tex]

We are given the volume and we are asked to find the radius.

We can solve for [tex]r[/tex] in the equation for volume to evaluate the radius.

[tex]\frac{4}{3}\pi r^3=V[/tex]

Move [tex]\pi[/tex] and [tex]r^3[/tex] into the numerator.

[tex]\frac{4\pi r^3}{3}=V[/tex]

Divide both sides of the equation by 3.

[tex]4\pi r^3=3V[/tex]

Divide both sides of the equation by [tex]4\pi[/tex].

[tex]r^3=\frac{3V}{4\pi }[/tex]

Take the cube root of both sides to eliminate the exponent.

[tex]r=\sqrt[3]{\frac{3V}{4\pi }}[/tex]

Numerical Evaluation

Now we have an equation to evaluate [tex]r[/tex].

Given [tex]V=36[/tex]

The statement "generally, parametric estimating requires less information and time than analogous estimating." is False.

Parametric estimating and analogous estimating are two different methods used to estimate the cost of a project or the value of a parameter.

Parametric estimating uses statistical data and mathematical models to make predictions about the cost or value of a project. This method requires specific data and information about the project, such as historical data, vendor quotes, and cost of similar projects.

The advantage of parametric estimating is that it can be more accurate and precise than other methods, but it can also be time-consuming to gather the necessary data and perform the calculations. Analogous estimating, uses information from similar projects to make predictions about the cost or value of a project.

This method requires less data and information than parametric estimating, but it can be less accurate and precise. Analogous estimating is often used as a quick and rough estimate, or when there is not enough data available to use parametric estimating.

To determine these intervals, one can use the function's critical points, zeros, or other methods, such as testing values or using calculus.

The intervals over which a function is positive, negative, or equal to zero can be determined by analyzing the function's graph. If a function is positive over an interval, its graph is above the x-axis over that interval, meaning that its values are positive. If a function is negative over an interval, its graph is below the x-axis over that interval, meaning that its values are negative. If a function is equal to zero over an interval, its graph passes through the x-axis over that interval, meaning that its values are equal to zero. To determine these intervals, one can use the function's critical points, zeros, or other methods, such as testing values or using calculus.

The trigonometric form of the complex number is,  

-6+ i (-6) = 6√2( cos5pi/4 + i sin 5pi/4)

In mathematics, a complex number is an element of a number system that extends the real numbers with a specific element denoted i, called the imaginary unit and satisfying the equation {\displaystyle i^{2}=-1}; every complex number can be expressed in the form a + bi, where a and b are real numbers.

here, we have,

the complex number which we get from the given graph is,

-6+ i (-6)

so, a = -6

    b = -6

i.e. z = √a^2+b^2

        =6√2

so, we know,

The trigonometric form of a complex number:

z = |z| (cosα +i sinα)

now, cosα = a/|z|

                 = -1/√2

and, sinα = b/|z|

              = -1/√2

so, solving we get,

α = 5pi/4

i.e. -6+ i (-6) = 6√2( cos5pi/4 + i sin 5pi/4)

Hence, The trigonometric form of the complex number is,  

-6+ i (-6) = 6√2( cos5pi/4 + i sin 5pi/4)

Your answer should be 88

Step-by-step explanation:

The standard deviation changes as the  three digits 5, 5, and 20 add up to 30 and it would decrease.

Given that,

The three digits 5, 5, and 20 add up to 30 and have a mean of 10 as a result. To calculate the standard deviation, use software. utilize the sample standard deviation function. Give a two-decimal place precision to your response. Assume the data set now included a fourth value, 10, which is equal to the mean.

To find : How would the standard deviation change?

S = √∑(Xi - X)²/n-1

= √ (5-10)² + (5-10)² +(20-10)² / 2

= √ 25+25+ 100 / 2

= √ 75

= 8.66

S = √∑(Xi - X)²/n-1

= √ (5-10)² + (5-10)² +(20-10)² + (10-10)² / 3

= 7.07

The probability that the pitcher will throw fewer than 4 pitches to a batter is 0.35

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

P(E) = Number of favourable outcomes / total number of outcomes

This probability distribution is shown below:

Pitch                   1            2        3          4         5

Frequency         15         20      40        15        10

Probability         0.15     0.2      0.4      0.15      0.1

Thus the probability that the pitcher will throw fewer than 3 pitches to a batter = P(X < 4)

X  is the number of pitches thrown.

Therefore:

P(X < 4) = P(X = 1) or P(X = 2)

The additive rule of the probability states that if two events X and Y are dependent events, the probability of X or Y occurring is the sum of their individual probability.

P(X < 4) = P(X = 1) or

P(X = 2) = P(X = 1) + P(X = 2)

= 0.15 + 0.2

= 0.35
