Find AB if A(-1,7) and B (11, -1). Round your answer to the nearest tenth.

If the scale upon which points a, b, c, and d are shown is an ordinal scale, we can meaningfully say that the order of the points represents the order of the underlying variable being measured.

When using an ordinal scale, the order of the points (a, b, c, and d) represents the relative ranking or ordering of the underlying variable being measured. This means we can determine which point is higher or lower in the ranking. For example, if the variable being measured is satisfaction level, we can say that point "c" represents higher satisfaction than point "a" or "b." However, with an ordinal scale, we cannot make precise quantitative comparisons between the points or determine the exact magnitude of the differences between them. The scale only allows us to establish the relative order or ranking of the points.

Step-by-step explanation:

The basic function equivalent to the piecewise-defined function f(x) = x if x ≥ 0 and -x if x < 0 is f(x) = |x|, which represents the absolute value of x.

The given piecewise-defined function f(x) has different expressions for different intervals. For x greater than or equal to zero, f(x) takes the value of x. For x less than zero, f(x) is equal to -x. We need to find a basic function that captures this behavior.

Among the options provided, f(x) = |x| is equivalent to the given piecewise function. The absolute value function, denoted by |x|, returns the positive value of x regardless of its sign. When x is non-negative, |x| equals x, and when x is negative, |x| is equal to -x, mirroring the conditions of the piecewise-defined function.

The function f(x) = |x| represents the absolute value of x and matches the behavior of the given piecewise-defined function, making it the equivalent basic function.

In summary, the basic function equivalent to the piecewise-defined function f(x) = x if x ≥ 0 and -x if x < 0 is f(x) = |x|, which represents the absolute value of x.

The function that represent the parent function y=x^2 after it has been translated 3 up and 2 right  is g(x) = (x - 2)^2 + 3

First, let's define the two transformations:

Vertical shift.

If we have a function f(x), a vertical shift of N units is written as:

g(x) = f(x) + N

This will move the graph of f(x) up or down a distance of N units.

if N is positive, then the shift is upwards

if N is negative, then the shift is downwards.

Horizontal shift.

If we have a function f(x), a horizontal shift of N units is written as:

g(x) = f(x + N)

This will move the graph of f(x) to the right or left a distance of N units.

if N is positive, then the shift is to the left

if N is negative, then the shift is to the right.

Then we start with the function f(x) = x^2

A shift of 3 units up is written as:

g(x) = f(x) + 3

And a shift of 2 units to the right is written as:

g(x) = f(x - 2) + 3

Replacing by the original function we get:

g(x) = (x - 2)^2 + 3

Answer:

Se refieren a las unidades de tiempo del sistema sexagesimal

9:25 son 9 minutos y 25 segundos

33:41:38 son 33 horas, 41 minutos y 38 segundos.

Step-by-step explanation:

El sistema sexagesimal se utiliza para medir tiempos y ángulos.

El tiempo se mide en horas,minutos y segundos

En cambio, los ángulos se miden en grados,minutos y segundos.

Los dos puntos '':'' sirven para separar las unidades.

La base de este sistema es el número 60 :

60 segundos ⇒ 1 minuto

60 minutos ⇒ 1 hora

Eso en cuanto a tiempo

En cuanto a grados :

60 segundos ⇒ 1 minuto

60 minutos ⇒ 1 grado

Cuando tengo dos números como en 9:25 , el número de la derecha corresponde a los segundos y el de la izquierda a los minutos

Entonces, 9:25 son 9 minutos y 25 segundos

Por otro lado, cuando tengo 3 números, como en 33:41:38, el número de la derecha corresponde a los segundos, el de en medio al de los minutos y el de la izquierda al de las horas (si nos referimos a unidades de tiempo).

Entonces, 33:41:38 son 33 horas, 41 minutos y 38 segundos.

Answer:

It should be C because of the given information is just (any) x 2

Step-by-step explanation:

We can say with 95% confidence that the true mean amount that women in the population spend dining out per week lies within the range of $91.74 to $108.26.

Based on the given information, we can calculate a 95% confidence interval for the mean amount that women in the population spend dining out per week. With a sample size of 25 and a standard error of $4, we can use the formula:

95% CI = sample mean +/- (critical value x standard error)

To find the critical value, we need to look up the t-distribution with degrees of freedom (df) = n-1 = 24 and a significance level of alpha = 0.05/2 = 0.025 (since we are interested in a two-tailed test). From a t-table or calculator, we find that the critical t-value is approximately 2.064.

Plugging in the values, we get:

95% CI = $100 +/- (2.064 x $4)
95% CI = $100 +/- $8.26
95% CI = ($91.74, $108.26)

Therefore, we can say with 95% confidence that the true mean amount that women in the population spend dining out per week lies within the range of $91.74 to $108.26. This means that if we were to repeatedly take random samples of 25 women and calculate their mean amount spent dining out, about 95% of the intervals we construct using this method would contain the true population mean.

If 400 hypothesis tests are conducted with a null hypothesis assumed to be true and using a significance level of 1%, approximately 4 tests will incorrectly find significance. This is because 1% of 400 is 4 (0.01 x 400 = 4).

If the null hypothesis is true, then we would expect approximately 1% of the tests to result in a Type I error, which is incorrectly rejecting the null hypothesis. Therefore, out of the 400 tests conducted at a significance level of 1%, we would expect approximately 4 tests to incorrectly find significance.

The difference between the height (h) and the slant height (L) of the pyramid is that the height measures the vertical distance from the apex to the base, while the slant height measures the length along the surface of the pyramid from the apex to any point on the base's edge.

The height (h) of a pyramid refers to the perpendicular distance between its base and its apex. It is the vertical measurement from the highest point of the pyramid to the base. In the given context, the specific value of the height (h) is not provided, so we cannot determine its exact value.

On the other hand, the slant height (L) of a pyramid refers to the length of the line segment that connects the apex of the pyramid to any point on the edge of its base. The slant height is measured along the surface of the pyramid, forming an inclined line from the apex to the base. In this case, the slant height is given as 10.50 units.

Therefore, the difference between the height (h) and the slant height (L) of the pyramid is that the height measures the vertical distance from the apex to the base, while the slant height measures the length along the surface of the pyramid from the apex to any point on the base's edge.

The value of x that satisfies the equation is x = 15/8, which is equivalent to 1.875.

To solve the equation (2/3)x - (1/5)x = x - 1 and find the value of x, we can follow these steps:

Combine like terms on the left side of the equation:

(2/3 - 1/5)x = x - 1

Find a common denominator for the fractions on the left side. The common denominator for 3 and 5 is 15, so we rewrite the equation as:

(10/15 - 3/15)x = x - 1

Simplify the left side of the equation:

(7/15)x = x - 1

To eliminate the fraction, we can multiply both sides of the equation by the denominator of the fraction, which is 15:

15 * (7/15)x = 15 * (x - 1)

This simplifies to:

7x = 15x - 15

Subtract 15x from both sides of the equation to isolate the x term:

7x - 15x = -15

Simplifying further:

-8x = -15

Divide both sides of the equation by -8 to solve for x:

x = (-15) / (-8)

Simplifying the division:

The partial sum of the given sequence, 1 + 10 + 19 + ... + 199, can be found by identifying the pattern and using the formula for the sum of an arithmetic series.  Hence, the partial sum of the sequence 1 + 10 + 19 + ... + 199 equals 4497.

To find the partial sum of the given sequence, we can observe the pattern in the terms. Each term is obtained by adding 9 to the previous term. This indicates that the common difference between consecutive terms is 9.

The formula for the sum of an arithmetic series is Sₙ = (n/2)(a + l), where Sₙ is the sum of the first n terms, a is the first term, and l is the last term.

In this case, the first term a is 1, and we need to find the value of l. Since each term is obtained by adding 9 to the previous term, we can determine l by solving the equation 1 + (n-1) * 9 = 199.

By solving this equation, we find that n = 23, and the last term l = 199.

Substituting the values into the formula for the partial sum, we have:

S₂₃ = (23/2)(1 + 199),

= 23 * 200,

= 4600.

However, this sum includes the terms beyond 199. Since we are interested in the partial sum up to 199, we need to subtract the excess terms.

The excess terms can be calculated by finding the sum of the terms beyond 199, which is (23/2)(9) = 103.5.

Therefore, the partial sum of the given sequence is 4600 - 103.5 = 4496.5, or approximately 4497 when rounded.

Hence, the partial sum of the sequence 1 + 10 + 19 + ... + 199 equals 4497.

Option C. No, because the 100 adults were selected without replacement, the selections are dependent.

The binomial probability formula assumes that the trials are independent, meaning that the probability of success or failure for each trial remains the same regardless of the outcomes of previous trials. However, in this case, the 100 adults were selected without replacement, so the probability of being left-handed for each selection depends on the outcomes of previous selections. Therefore, the binomial probability formula cannot be used to find the probability in this situation. Instead, the hypergeometric distribution can be used to account for the dependence between selections.

It is assumed that approximately 15% of adults in the U.S. are left-handed. Consider the probability that among 100 adults selected in the U.S., there are at least 30 who are left-handed. Given that the adults surveyed were selected without replacement, can the probability be found by using the binomial probability formula with x counting the number who are left-handed? Why or why not?

A. Yes, because the 100 adults represent less than 5% of the U.S. adult population, the trials can be treated as independent.

B. No, because the 30 adults represent more than 5% of the sample size, the trials are dependent.

C. No, because the 100 adults were selected without replacement, the selections are dependent.

D. No, because the probability of being right-handed is greater, x must count the number of right-handed adults.

Hattie's strategy of thinking that her probability of getting the marble increases as the volume of the cake decreases does not make sense.

Hattie's strategy is based on a flawed assumption. In the context of randomly choosing a slice with a hidden marble, the probability of Hattie getting the marble does not change as the volume of the cake decreases.

The distribution of marbles within the cake is fixed regardless of its size. Each slice has an equal chance of containing the marble, irrespective of the remaining volume of the cake.

To illustrate this, consider a simplified scenario with two slices. Initially, the cake is whole, and the probability of Hattie getting the marble is 1/2.

If Hattie chooses the first slice without the marble, the remaining volume decreases, but the probability of the second slice containing the marble remains 1/2.

The volume of the cake does not affect the marble's location or the equal probabilities associated with each slice.

Therefore, Hattie's strategy of thinking her probability increases as the volume of the cake decreases is not rational and does not align with the principles of probability.

The typical margin of error in a sample survey of 1,500 respondents is about 2.5 to 3 percent.

Most surveys provide a margin of error or a confidence interval of some type to quantify the level of accuracy. The margin of error, often represented as a percentage, depicts the range in which the real survey results can fluctuate.

The size of the sample and the degree of variability in the population are the two most crucial elements that influence the margin of error in a survey. It's generally agreed that the bigger the sample size, the lower the margin of error, and the more precise the findings. The margin of error shrinks as the sample size grows.
