A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 23.2 pounds and a standard deviation of 6.6 pounds. Step 2 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 65 people on this diet, what would be the standard deviation of the sampling distribution of sample means
Answer:
The standard deviation of the sampling distribution of sample means would be 0.8186.
Step-by-step explanation:
We are given that
Mean of population=23.2 pounds
Standard deviation of population=6.6 pounds
n=65
We have to find the standard deviation of the sampling distribution of sample means.
We know that standard deviation of the sampling distribution of sample means
=[tex]\frac{\sigma}{\sqrt{n}}[/tex]
Using the formula
The standard deviation of the sampling distribution of sample means
=[tex]\frac{6.6}{\sqrt{65}}[/tex]
[tex]=0.8186[/tex]
Hence, the standard deviation of the sampling distribution of sample means would be 0.8186.

If the total area of a dartboard is 804 in2 and the area of the bull's-eye is 50in2, what is the probability that a dart that randomly hits the dartboard will hit the bull's-eye?
Answer:
6.2%, option A.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
The desired area to hit is of 50 in², while the total area is of 804 in². Thus, the probability of hitting the bull's-eye is:
[tex]p = \frac{50}{804} = 0.062[/tex]
0.062*100% = 6.2%.

Describe how the graph of y= x2 can be transformed to the graph of the given equation. (2 points) y = (x-4)2-8
Answer:
The description is that the function was translated 4 units to the right and 8 units down.
Step-by-step explanation:
Translations:
Translating a function f(x) a units to the right is the same as finding f(x - a).
Translating a function f(x) a units to the left is the same as finding f(x + a).
Translating a function f(x) a units up is the same as finding f(x) + a.
Translating a function f(x) a units down is the same as finding f(x) - a.
y= x² to y = (x-4)²-8
First at the domain, x becomes x - 4, so f(x) becomes f(x - 4), that is, the function was translated 4 units to the right.
Then the function is subtracted by 8, that is, it was translated 8 units down.
The description is that the function was translated 4 units to the right and 8 units down.

De acuerdo a las propiedades básicas de los triángulos ¿Cuánto suman los punto
ángulos internos de un triángulo?
180°
X
360°
Answer:
180°
Step-by-step explanation:
Una de las propiedades básicas de los triángulos, nos dice que para todo triángulo, la suma de los 3 ángulos internos es siempre igual a 180°.
Esto lo podemos comprobar si trazamos una regla paralela a uno de los lados que pase por el vértice opuesto a ese lado.
Podemos ver que el ángulo generado por una línea recta (un ángulo llano, es decir de 180°) es formado por el ángulo correspondiente al vértice que corta la línea y a dos ángulos de igual medida que los otros ángulos internos del triángulo.
Esto se puede observar en el dibujo de abajo (aunque el dibujo no sea muy prolijo, es suficiente para entender la idea).

Use a linear approximation (or differentials) to estimate the given number. (Round your answer to two decimal places.) (32.03)4/5
Answer:
16.024
Explanation:
Using linear approximation:
We breakdown the numbers in order to solve thus:
[32(1 + 0.1875)]^0.8
= (32^0.8)*(1 + 0.001875)^0.8
= 16* (1 + 0.8*0.001875)
= 16*(1.0015)
= 16.024
The estimated value of the given number is 16.02
What is linear approximation?A linear approximation is an approximation of a general function using a linear function. They are widely used in the method of finite differences to produce first order methods for solving or approximating solutions to equations.
[tex]f(x) = x^{4/5}[/tex] at [tex]x_o = 32\\[/tex] [tex]\Delta\ x = 0.05[/tex]
[tex]f(x) = 32^{4/5} = 16[/tex]
[tex]f'(x) = (4/5)x^{-1/5}\\\\f'(32) = (4/5)32^{-1/5}\\\\= 0.4[/tex]
[tex]L(x) = 0.4(x-32)+16 = x^{4/5}\\\\L(32.05) = 0.4(32.05-32)+16\\\\= 16.02 \\\\= (32.05)^{4/5}[/tex]
Hence, the estimated value of the given number is 16.02

A TV repair service company has a seasonal demand for its service,and there is a general shortage of skilled TV repair persons.Which one of the following is a capacity production planning alternative suitable for this situation?
A) Hire and lay off workers to match the demand requirements.
B) Increase the backlog for short-term demand surges.
C) Offer reduced prices during the slack season.
D) Build anticipation inventories.
Answer: increase the backlog for short term demand surges
Step-by-step explanation:
Since the TV repair service company has a seasonal demand for its service,and there is a general shortage of skilled TV repair persons, the capacity production planning alternative that's suitable for this situation will be to increase the backlog for short-term demand surges.
Offering reduced prices during the slack season isn't appropriate as this will lead to a reduction in revenue. Building anticipation inventories is also wrong as there may be differences in the forecast made.

The number of potholes in any given 1 mile stretch of freeway pavement in Pennsylvania has an approximate normal distribution with mean 50 and a standard deviation 10. Use the Empirical Rule to determine the approximate proportion of 1-mile long roadways with potholes numbering between 20 and 70.
Answer:
The approximate proportion of 1-mile long roadways with potholes numbering between 20 and 70 is 0.9735.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 50, standard deviation = 10.
Between 20 and 70.
The normal distribution is symmetric, which means that 50% of the measures are below the mean and 50% are above.
20
20 = 50 - 3*10
So 20 is 3 standard deviations below the mean. Of the 50% of the measures below the mean, 99.7% are within 3 standard deviations of the mean, that is, above 20.
70
70 = 50 + 2*10
So 70 is 2 standard deviations above the mean. Of the 50% of the measures above the mean, 95% are within 2 standard deviations of the mean, that is, below 70.
Percentage:
0.997*50% + 0.95*50% = 97.35%
As a proportion, 97.35%/100 = 0.9735.
The approximate proportion of 1-mile long roadways with potholes numbering between 20 and 70 is 0.9735.

A sample of a radioactive substance decayed to 97% of its original amount after a year. (Round your answers to two decimal places.) (a) What is the half-life of the substance
Answer:
23 years
Step-by-step explanation:
Step 1: Calculate the rate constant (k) for the radioactive decay
A radioactive substance with initial concentration [A]₀ decays to 97% of its initial amount, that is, [A] = 0.97 [A]₀, after t = 1 year. Considering first-order kinetics, we can calculate the rate constant using the following expression.
ln [A]/[A]₀ = - k.t
k = ln [A]/[A]₀ / -t
k = ln 0.97 [A]₀/[A]₀ / -1 year
k = 0.03 year⁻¹
Step 2: Calculate the half-life of the substance
We will use the following expression.
[tex]t_{1/2}[/tex] = ln2/ k = ln 2 / 0.03 year⁻¹ = 23 years
