Un bolígrafo pesa 6,4 g. Cuantos bolígrafos necesitamos para superar el kilogramo?

Answers

Answer 1

Based on th mentioned iinformations, we would be requiring about 157 pens (rounded up) in order to exceed the weight of 1 kilogram.

There are 1000 grams in a kilogram. To find out how many pens are needed to exceed 1 kilogram, we need to divide 1000 grams by the weight of one pen:

1000 g / 6.4 g = 156.25 pens

Therefore, we would need 157 pens (rounded up) to exceed 1 kilogram.

Dividing 1000 grams by the weight of one pen gives us the number of pens that would weigh 1000 grams or 1 kilogram, which turns out to be 156.25 pens. Since we cannot have a fractional part of a pen, we round up to 157 pens to ensure that their total weight exceeds 1 kilogram.

Answers

The left of z as 0.9306, which corresponds to a z-score of approximately 1.48.

To solve this problem, we can use a standard normal distribution table or calculator to find the z-score corresponding to a cumulative area of 0.93.

We know that the area to the right of z will be 0.07 (since we want 7% of the area under the standard normal curve to lie to the right of z). Therefore, the area to the left of z will be 1 - 0.07 = 0.93.

A standard normal distribution table or calculator provides the cumulative probability (area) to the left of a given z-score. For example, a table may list the cumulative area to the left of z as 0.9306, which corresponds to a z-score of approximately 1.48.

For a set of five positive integers, none greater than 100, the mean is 1.5 times the mode. If 31, 58, 98, x, and x are the five integers, what is the value of x?

Answers

Answer: the value of x is 34.

Step-by-step explanation: Let's start by finding the mode of the set of integers. The mode is the number that appears most frequently in the set.

From the given integers, we can see that x appears twice, and all other numbers appear only once. Therefore, the mode is x.

Now we are told that the mean of the set is 1.5 times the mode. We can set up an equation to represent this:

(mean) = 1.5 * (mode)

To find the mean, we can add up all the numbers in the set and divide by the total number of integers:

(mean) = (31 + 58 + 98 + x + x) / 5

Simplifying the expression on the right:

(mean) = (187 + 2x) / 5

Substituting this expression for the mean into our equation:

(187 + 2x) / 5 = 1.5x

Multiplying both sides by 5 to eliminate the fraction:

187 + 2x = 7.5x

Subtracting 2x from both sides:

187 = 5.5x

Dividing both sides by 5.5:

x = 34

Therefore, the value of x is 34.

The value of x is 34

The two sides with lengths of 6 and 3 will not satisfy the Triangle Inequality Theorem, which shows that there is no way to construct a triangle in which the sum of the lengths of two of the sides is less than or equal to the length of the third side.

Given data ,

Let the triangle be represented as ΔABC

Now , the lengths of the sides of the triangle are

AB = 6 units

BC = 3 units

AC = 9 units

Now , The Triangle Inequality Theorem states that the following requirements must be met for any triangle with sides measuring a, b, and c:

which conditions of p, t, and n, respectively, are most ideal?group of answer choiceshigh p, high t, high nlow p, low t, low nhigh p, low t, high nlow p, high t, high nlow p, high t, low n

Answers

In the context of ideal gas behavior, the most ideal conditions for the parameters pressure (P), temperature (T), and number of moles (n) depend on the specific situation or application. However, I can provide general insights for each parameter.

1. Low pressure (P): Ideal gas behavior is best approximated when the pressure is low. This is because the gas molecules have more space to move around, minimizing their interactions with each other and making their behavior more predictable.

2. High temperature (T): Ideal gas behavior is more accurate at higher temperatures because the gas molecules have more kinetic energy. This allows them to move more freely, reducing the influence of intermolecular forces that can deviate the gas from ideal behavior.

3. High number of moles (n): Having a high number of moles means there are more gas molecules present. This generally improves the accuracy of ideal gas predictions because the behavior of individual molecules tends to average out, leading to more predictable and consistent results.

Considering these factors, the most ideal conditions for P, T, and n are low pressure, high temperature, and high number of moles, respectively. This corresponds to the option: low P, high T, and high n.

Answers

The standard deviation of the possible outcomes is approximately 15.24 hours.

To calculate the standard deviation of the possible outcomes, we first need to find the mean or expected value of the work hours. We can do this by multiplying each work hour by its corresponding probability, and then summing up the results:

Expected value = (0.3 x 45) + (0.2 x 40) + (0.4 x 25) + (0.1 x 12) = 30.3

Next, we need to find the variance of the possible outcomes. The variance is the average of the squared deviations of each outcome from the expected value. We can calculate the variance using the formula:

Variance = (sum of (x - mean)^2 * probability)

where x is the work hours and the sum is taken over all possible outcomes.

Variance = (0.3 x (45 - 30.3)^2) + (0.2 x (40 - 30.3)^2) + (0.4 x (25 - 30.3)^2) + (0.1 x (12 - 30.3)^2) = 231.87

Finally, we can calculate the standard deviation as the square root of the variance:

Standard deviation = sqrt(231.87) = 15.24

A 255 in.2
B. 370 in.2
c. 391 in.2
D. 421 in.2

Answers

Answer:

D. 421 in.².

Step-by-step explanation:

To determine the amount of wrapping paper needed to cover the shirt box, Patrick needs to calculate the surface area of the box.

The surface area of a rectangular box can be calculated by adding the area of each of its six faces. In this case, the box has two faces that measure 10 in. by 1.5 in., two faces that measure 17 in. by 1.5 in., and two faces that measure 10 in. by 17 in.

So, the total surface area of the box is:

2(10 in. x 1.5 in.) + 2(17 in. x 1.5 in.) + 2(10 in. x 17 in.)

= 30 in.² + 51 in.² + 340 in.²

= 421 in.²

Therefore, Patrick will need 421 in.² of wrapping paper to cover the rectangular shirt box.

So the maximum number of edges in an undirected graph with 100 vertices is 4950.

In an undirected graph, each edge connects two vertices, and as such, it is counted twice, once for each vertex it connects. Therefore, the total number of edges in the graph is the sum of the degrees of all vertices, divided by 2.

In a complete graph with n vertices, every vertex is connected to every other vertex, except itself, and so the degree of each vertex is n-1 (it is connected to n-1 other vertices). Therefore, the total number of edges in the graph is:

n * (n-1) / 2

Answers

The appropriate minimum sample size for each group is n1 = n2 ≥ 964. To find the appropriate minimum sample sizes for estimating the difference between two means with a 95% margin of error equal to ±5 .

Standard deviations (σ1 and σ2) both approximately equal to 39.7, we can use the following formula:


[tex]n1 = n2 ≥ (Z * (σ1 + σ2) / E)²[/tex]

Where:
- n1 and n2 are the minimum sample sizes for the two groups
- Z is the Z-score corresponding to the desired confidence level (95%)
- σ1 and σ2 are the standard deviations of the two groups (both ≈ 39.7)
- E is the desired margin of error (±5)

From a standard normal (Z) table, we can find the Z-score for a 95% confidence level, which is 1.96. Since the sample sizes are equal and the standard deviations are approximately the same, we can simplify the formula as follows:

n1 = n2 ≥ (1.96 * (39.7 + 39.7) / 5)²

n1 = n2 ≥ (1.96 * 79.4 / 5)²

n1 = n2 ≥ (31.0376)²

the width of a rectangle is 3 in shorter than its length. if the area is 28 in, what are the dimensions of the rectangle?

Answers

If the width of a rectangle is 3 in shorter than its length and area is 28 in. The dimensions of the rectangle are:

Length = 7 inchesWidth = 4 inches

According to the given information, the width is 3 inches shorter than the length, so we can express this relationship as:

W = L - 3

The area of a rectangle is calculated by multiplying its length and width:

Area = Length × Width

Given that the area is 28 square inches, we can write the equation:

28 = L × W

Substituting the expression for the width, we have:

28 = L × (L - 3)

Expanding the equation:

28 = L^2 - 3L

Rearranging the equation into a quadratic form:

L^2 - 3L - 28 = 0

To solve this quadratic equation, we can factor it or use the quadratic formula. Let's use the quadratic formula:

L = (-b ± sqrt(b^2 - 4ac)) / (2a)

For our equation, a = 1, b = -3, and c = -28. Substituting these values into the formula, we get:

L = (-(-3) ± sqrt((-3)^2 - 4(1)(-28))) / (2(1))

L = (3 ± sqrt(9 + 112)) / 2

L = (3 ± sqrt(121)) / 2

L = (3 ± 11) / 2

So we have two possible values for L:

L1 = (3 + 11) / 2 = 14 / 2 = 7

L2 = (3 - 11) / 2 = -8 / 2 = -4

Since length cannot be negative, we discard the negative value.

Now, we can find the corresponding width using the relationship W = L - 3:

W = 7 - 3 = 4

Therefore, the dimensions of the rectangle are:

or, 3/4 = 0.2-(m-3)

or, m-3 = -0.55

or, m = 2.45

Hence, The solution is, the simplification of 1-|0.2-(m-3)+1/4|=0 is m = 2.45.

x=13+2y

x-2y = 13

Please help I need this turned in by tmr!!!

Answers

Answer: That's correct! The equation x = 13 + 2y can be rearranged to x - 2y = 13.

Step-by-step explanation:

Assume that the random variable X is normally distributed with mean 70 and standard deviation 8. Find the 40th percentile for X.

Answers

The 40th percentile for X is approximately  67.98. To find the 40th percentile for X, we need to use a standard normal distribution table or calculator.

We first need to standardize the random variable X by subtracting the mean and dividing by the standard deviation:

z = (X - mean) / standard deviation
z = (X - 70) / 8

We can then find the z-score corresponding to the 40th percentile, which is -0.253:

z = invNorm(0.4)
z = -0.253

Using this z-score and the formula for standardizing a random variable, we can solve for X:

z = (X - 70) / 8
-0.253 = (X - 70) / 8
-2.024 = X - 70
X = 67.976

Therefore, the 40th percentile for X is approximately 67.98.

option a is correct

Let X and Y be two independent uniform random variables on (0, 1).
(a) Using the convolution formula, find the p.d.f. fZ(z) of the random variable Z = X + Y , and graph it.
(b) What is the moment generating function of Z?

Answers

(a) To find the probability density function (pdf) of Z = X + Y, we can use the convolution formula:

fZ(z) = ∫_{-∞}^{∞} fX(x) fY(z - x) dx

Since X and Y are both uniformly distributed on (0,1), we have:

fX(x) = fY(y) = 1, for 0 < x,y < 1

Substituting these expressions, we get:

fZ(z) = ∫_{0}^{1} 1 * 1 dz - ∫_{0}^{z} 1 * 1 dx = z, for 0 < z < 1

fZ(z) = 0, for z ≤ 0 or z ≥ 1

Therefore, the pdf of Z is:

fZ(z) = {

z, 0 < z < 1,

0, otherwise.

}

(b) To find the moment generating function (MGF) of Z, we can use the definition:

M_Z(t) = E[e^{tZ}] = ∫_{-∞}^{∞} e^{tz} fZ(z) dz

Using the pdf of Z, we get:

M_Z(t) = ∫_{0}^{1} e^{tz} z dz = [(ze^{tz})/(t^2)]|_{0}^{1} = (e^t - 1)/t^2, for t ≠ 0

M_Z(t) = 1, for t = 0

Therefore, the MGF of Z is:

M_Z(t) = {

(e^t - 1)/t^2, t ≠ 0,

1, t = 0.

}

Note that the MGF is defined only for values of t for which the integral converges.
