Entre que valores varía la masa corporal MC de la mayoría de estudiantes?

Answers

Answer 1

The majority of students have a body mass between 46.7 and 79.1 kg, and there are 36 students with a body mass of 61.7 kg or greater.

Assuming a normal distribution of body mass among the students, we can use the concept of standard deviation to answer the question. Let's assume that the mean body mass of the students is 60 kg, and the standard deviation is 5 kg.

To find the range of body mass where the majority of students fall, we can use the empirical rule, which states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% within two standard deviations, and 99.7% within three standard deviations.

Therefore, the range of body mass where the majority of students fall is between 55 kg (60 kg - 5 kg) and 65 kg (60 kg + 5 kg).

To find the number of students with a body mass equal to or greater than 61.7 kg, we need to find the z-score of 61.7 kg, which is

(61.7 - 60) / 5 = 0.34.

We can then use a standard normal distribution table to find the proportion of the area to the right of this z-score, which is 0.3665. This means that approximately 36.65% of the students have a body mass equal to or greater than 61.7 kg.

Use the image to determine the type of transformation shown.

Horizontal translation
Vertical translation
Reflection across the x-axis
90° clockwise rotation

(Use Image added)

Answers

Answer:

Vertical translation

Step-by-step explanation:

Let's compare each point to its corresponding point in the image.

First, look at point A. Look at point A'.

With respect to the shapes ABCD and A'B'C'D', they are in the same position (in between B/B' and D/D'; across from C/C').

If you look at the image again, you'll find that the shape A'B'C'D' is not a rotated version of ABCD.

Thus, we can rule out the option "90° clockwise rotation."

A reflection across the x-axis indicates that A'B'C'D' and ABCD would be symmetrical across the x-axis (a horizontal line).

Because ABCD and A'B'C'D' are not symmetrical across a horizontal line, we can also rule out "Reflection across the x-axis."

Now, look at the position of A'B'C'D' with respect to ABCD. It's directly next to ABCD. In other words, it was shifted sideways.

Translations are basically just shifts.

Recall that horizontal means up and down, while vertical means side to side.

Since this is a sideways shift, we can conclude that the translation was:

a vertical translation.

Mathematical operations including multiplication, division, addition, and subtraction are possible. The construction of an expression looks like this: Expression, number, and mathematical operator Numbers, variables, and functions are the elements of a mathematical expression (such as addition, subtraction, multiplication, and division, etc.). Expressions and phrases can be contrasted. Expressions are any equations that comprise numbers, variables, and an arithmetic operation. They are occasionally referred to as algebraic expressions. For instance, the value of m in the computation of 4m + 5 is the same as the word m in the provided equation, which has been separated from the figures 4m and 5 by the mathematical symbol +.

given,

Since subtracting a negative integer is equivalent to adding its positive counterpart, the expressions "10 - (-2)" as well as "-10 + 2" have the same meaning.

To be more precise, "10 - (-2)" denotes starting with a value of 10 and then deducting a negative value of -2. The positive value of an amount that is negative may be subtracted without affecting it, and vice versa. Therefore, "10 - (-2)" equals "10 + 2," making 12 the result.

The expression "-10 + 2" on the opposite hand suggests that we start with an amount of -10 and subsequently add a value of 2.

A positive number is equal to its negative counterpart when added to a negative number. Because of this, "-10 + 2" equals "-10 - (-2)", which also equals 12.

Therefore, both expressions represent the same value of 12.

Factorization is the process of finding the factors of a given number or expression. A factor is a number or expression that divides the original number or expression without leaving a remainder. In other words, factorization is the process of expressing a number or expression as a product of its factors.

For example, the number 12 can be factored into 2 and 6, or into 3 and 4, because 2 and 3 are factors of 12 and their product gives 12. Similarly, the expression x^2 - 4 can be factored into (x+2)(x-2), because if we multiply (x+2) and (x-2), we get x^2 - 4.

Ganymede, one of the moons of Jupiter, can be modeled by a sphere with a diameter of approximately 3,388 kilometers. The Moon of Earth, by comparison, can be modeled by a sphere with a diameter of approximately 1,245 kilometers. The volume of Ganymede is approximately how many times the volume of Earth’s Moon?

Answers

The volume of Ganymede is approximately 3.48 times the volume of the Moon, based on the given diameters of the two moons and the formula for the volume of a sphere.

What is volume of a sphere?

The volume of a sphere is the amount of space occupied by the sphere in three-dimensional space. It can be calculated using the formula V = (4/3)πr³, where V is the volume of the sphere, r is the radius of the sphere, and π (pi) is a mathematical constant approximately equal to 3.14159. This formula states that the volume of a sphere is four-thirds of the product of pi and the cube of the sphere's radius.

In the given question,

The volume of a sphere can be calculated using the formula V = (4/3)πr³, where r is the radius of the sphere. Since we are given the diameters of the two moons, we can calculate their radii by dividing the diameters by 2. Therefore, the radius of Ganymede is 3,388/2 = 1,694 km, and the radius of the Moon is 1,245/2 = 622.5 km.

Now, we can calculate the volumes of the two moons:

V_Ganymede = (4/3)π(1694)³ ≈ 7.66 x 10^10 km³

V_Moon = (4/3)π(622.5)³ ≈ 2.2 x 10^10 km³

To find how many times larger Ganymede's volume is compared to the Moon's volume, we can divide the volume of Ganymede by the volume of the Moon:

V_Ganymede / V_Moon ≈ (7.66 x 10¹⁰) / (2.2 x 10¹⁰) ≈ 3.48

Therefore, the volume of Ganymede is approximately 3.48 times the volume of the Moon.

summation notation for the series
7+11+15+…+203+207

Answers

The series can be represented in summation notation as follows: ∑(n = 7 to 207) (4n - 1)

What is the summation?

In this notation, the Greek letter sigma (∑) represents the summation symbol, and n represents the index of summation. The series starts from n = 7 and goes up to n = 207, with each term being (4n - 1). The notation "n = 7 to 207" indicates the range of values that n takes on in the summation. The expression (4n - 1) represents the general term in the series, which changes as n varies from 7 to 207.

Summation notation, denoted by the Greek letter sigma (∑), is a shorthand way to represent the sum of a sequence of numbers. In this case, the series you provided is:

7 + 11 + 15 + … + 203 + 207

The general term of the series, which changes as "n" varies, is (4n - 1). This means that for each value of "n", we substitute it into the expression (4n - 1) to get the corresponding term in the series. For example, when "n" is 7, the corresponding term is (4 * 7 - 1) = 27. When "n" is 11, the corresponding term is (4 * 11 - 1) = 43, and so on, up to "n" = 207.

The summation notation "∑(n = 7 to 207) (4n - 1)" represents the sum of all the terms in the series, where "n" takes on values from 7 to 207, and the term for each "n" is (4n - 1). This notation allows us to compactly represent the entire series in a concise mathematical form.

The absolute maximum value of f(x)= x^3 -3x^2 +12 on the closed interval [-2,4] occurs at x=a) 4b) 2c) 1d) 0e) -2

Answers

The absolute maximum value of f(x) on the closed interval [-2, 4] occurs at x = -2 and x = 0, and the maximum value is 16. So the answer is option (e) -2.

To find the absolute maximum value of the function f(x) = x³ - 3x² + 12 on the closed interval [-2, 4], we need to evaluate the function at the critical points and at the endpoints of the interval, and then choose the largest value.

To find the critical points, we take the derivative of the function and set it equal to zero

f'(x) = 3x² - 6x = 3x(x - 2)

Setting f'(x) = 0 gives x = 0 and x = 2 as critical points.

Next, we evaluate the function at the critical points and at the endpoints of the interval

f(-2) = (-2)³ - 3(-2)² + 12 = 16

f(0) = (0)³ - 3(0)² + 12 = 12

f(2) = (2)³ - 3(2)² + 12 = 4

f(4) = (4)³ - 3(4)² + 12 = 4

Therefore, the correct option is (e) -2

We occasionally encounter operations with hills and valleys. Hill and valley points in polynomial functions typically have many locations. We are aware that these places, which can be categorized as maxima or minima, are the function's critical points. The valley points are referred to as minimal and the hill points are as maxima. We must determine the locations of the function's global maxima and global minima, which are known as the minimum and maximum values, respectively, due to the fact that there are several maxima and minima.

To find the absolute maximum value of the function [tex]f(x) = x^3 - 3x^2 + 12[/tex] on the closed interval [-2, 4], we need to examine the critical points and the endpoints of the interval.

First, find the critical points by taking the derivative of f(x) and setting it equal to 0:
[tex]f'(x) = 3x^2 - 6x\\0 = 3x^2 - 6x\\0 = 3x(x - 2)[/tex]

The critical points are x = 0 and x = 2.

Next, evaluate the function at the critical points and the interval endpoints:

[tex]f(-2) = (-2)^3 - 3(-2)^2 + 12 = -8 - 12 + 12 = -8\\f(0) = 0^3 - 3(0)^2 + 12 = 12\\f(2) = 2^3 - 3(2)^2 + 12 = 8 - 12 + 12 = 8\\f(4) = 4^3 - 3(4)^2 + 12 = 64 - 48 + 12 = 28[/tex]

the area of a rectangle is 30 cm squared, what is the height of the rectangle if the base is 4 cm

Answers

Answer:

7.5 cm.

Step-by-step explanation:

The height of a rectangle can be calculated using the rectangle's base and area using the following formula:

height = area / base

This formula can be derived from the formula for the area of a rectangle:

area = base x height

By rearranging this formula, we get:

height = area / base

Therefore, if we know the area and base of a rectangle, we can use this formula to calculate its height.

1) rewrite

Height = are / base

2) plug in

h = 30 cm / 4 cm

3) solve (divide)

height = 7.5 cm

Therefore, the height of the rectangle is 7.5 cm.

Answers

Answer: The correct answer is 8.12%-11.88%.

We can use the formula for a confidence interval for a proportion:

where p is the sample proportion, z* is the z-score corresponding to the desired level of confidence (in this case, 1.96 for a 95% confidence interval), and SE is the standard error of the proportion.

SE = sqrt(p*(1-p)/n) = sqrt(0.1*0.9/1015) = 0.0094

Plugging in the values, we get:

0.1 ± 1.96*0.0094

= 0.1 ± 0.0184

So the 95% confidence interval is (0.0816, 0.1184), which is equivalent to 8.12%-11.88%.

Equation for Angle 3- 90-38=52

Angle 3= 52

Angle 5= 38

Angle 6= 52

Step-by-step explanation:

Angle is 90 degrees.

Angle 2 is 38 degrees.

If you are just looking at the bottom half(Angle 6, Angle 1, and Angle 2) They are all supposed to add up to equal 180 degrees because it is a supplementary angle.

So you add 90 and 38 and it gives you 52(Angle 6).
90+38+52=180

Then a complementary angle is two angles that equal 90 degrees.

So if you take Angle 2(38 degrees) and subtract it from 90, you get 52. Which is Angle 3.

You do the same with Angle 6 and Angle 5.

Angle 6(52 degrees) subtract from 90 and you get 38.

Then you add 38 and 52 and you get 90.

Then 180-90=90, so Angle 4 is 90 degrees.

In Problems 55–62 write each function in terms of unit step functions. Find the Laplace transform of the given function. = {0, 0<_t<1 f(t) = {t^(2) t>_ 1

Answers

The Laplace transform of the given function f(t) = {0, 0 < t < 1, t², t ≥ 1} is 2s⁻³.

Given the function f(t) = {0, 0 < t < 1, t², t ≥ 1}, we need to find its Laplace transform. The Laplace transform of a function f(t) is denoted by F(s) and is defined as follows:

F(s) = L{f(t)} = ∫[0,∞) f(t)e⁻ᵃˣdt,

where s is a complex variable.

To find the Laplace transform of the given function, we need to split the function into two parts: one for 0 < t < 1 and another for t ≥ 1. For 0 < t < 1, f(t) = 0, so the integral becomes:

L{0} = ∫ 0e⁻ᵃˣdt = 0.

For t ≥ 1, f(t) = t², so the integral becomes:

L{t²} = ∫ t²e⁻ᵃˣdt.

To evaluate this integral, we can use integration by parts. Let u = t² and dv = e⁻ᵃˣdt, then du/dt = 2t and v = (-1/s) e⁻ᵃˣ. Using the integration by parts formula, we get:

L{t²} = ∫ t²e⁻ᵃˣdt = (-t²/s)e⁻ᵃˣ∣∣∣[0,∞) + (2/s)∫[0,∞) te⁻ᵃˣdt.

The first term in the above equation evaluates to zero because e⁻ᵃˣapproaches zero as t approaches infinity. Using integration by parts again for the second term, we get:

L{t²} = (-t²/s)e⁻ᵃˣ∣∣∣[0,∞) + (2/s)(-t/s)e⁻ᵃˣ∣∣∣[0,∞) + (2/s²)∫[0,∞) e⁻ᵃˣdt.

The first two terms in the above equation evaluate to zero for the same reason as before. The integral in the last term evaluates to (1/s²), so we get:

L{t²} = 2/s³.

Therefore, the Laplace transform of the given function f(t) is:

L{f(t)} = L{0} + L{t²} = 0 + 2/s³ = 2s⁻³.

slope-reliability) with respect to the 3-sigma rule used in reliability analysis, studies have shown that even experts tend to under-predict the range in parameter values (max-min). however, this is conservative because it leads to a smaller estimate of reliability. true false

Answers

The statement "with respect to the 3-sigma rule used in reliability analysis, studies have shown that even experts tend to under-predict the range in parameter values (max-min). however, this is conservative because it leads to a smaller estimate of reliability" is true because studies have shown that experts tend to under-predict the range in parameter values when using the 3-sigma rule, leading to a conservative estimate of reliability.

The 3-sigma rule is a widely used method in reliability analysis that assumes the range of parameter values is within three standard deviations of the mean value. However, studies have shown that experts tend to under-predict the range of parameter values.

This under-prediction can result in a conservative estimate of reliability because it leads to a smaller range of possible outcomes. In other words, the estimated reliability is likely to be lower than the actual reliability. Therefore, it is important to take into account the potential for under-prediction when using the 3-sigma rule and to use other methods to estimate reliability as well.

What is the domain of the radical function shown below?

What is the domain of the radical function shown below?

Answers

The required domain of the given function f(x) = √x+4 is (D) {x|x ≥ -4} respectively.

What is a domain?

The domain of a function is the set of values that we are allowed to enter into our function.

This collection includes the x values for functions like f(x).

The set of values that a function can accept as input is known as its range.

The function outputs this list of values once we enter an x value.

Think about the equation y = f(x), where x and y are the independent and dependent variables.

If a value for x successfully enables the creation of a single value y using another value for x, it is said to be in the domain of the function f.

Considering the function's expression:

f(x) = √x+4

We are aware that the set of input values for which the function is real and defined constitutes the function's domain.

We are aware that for the function to continue to be defined, the value included within the radical expression must be larger than or equal to 0.

x+4 ≥ 0

Take 4 off of both sides.

x+4-4 ≥ 0-4

x ≥ 4

Then, the domain is:
{x|x ≥ -4}

Therefore, the required domain of the given function f(x) = √x+4 is (D) {x|x ≥ -4} respectively.

how many square feet of carpet will we need for this hole

Answers

Answer: 44 ft²

Step-by-step explanation:

     We will find the area of the large rectangle and subtract the area of the square. The area of a rectangle (and square) can be used with this formula:

       A = LW

Large Rectangle:

       A = LW

       A = (12 ft)(4 ft)

       A = 48 ft²

Square:

       A = LW

       A = (2 ft)(2 ft)

       A = 4 ft²

Subtract:

48 ft² - 4 ft² = 44 ft²

if the mean and standard deviation of a population are 436 and 103 respectively, what is the standard error of the mean for a sample of size 8?

Answers

The standard error of the mean for a sample of size 8 and population mean 436 is equals to the 36.42.

The standard error of the mean, or usually say standard error, shows how different the population mean from a sample mean. We have a population with population mean, [tex]\mu[/tex] = 436

Standard deviations for population, [tex] \sigma[/tex] = 103

Sample size, n = 8

We have to determine the value of standard error of the mean. SEM is calculated simply as dividing the standard deviation by the square root of the sample size, n. Mathematically,

[tex]SE = \frac{ \sigma}{\sqrt n}[/tex]

Substitues all known values in above formula, [tex]= \frac{ 103}{\sqrt 8}[/tex]

= 36.42

Hence, required standard error value is 36.42.
