Answer:

False.

Step-by-step explanation:

In a normal distribution, 95% of the data falls within 2 standard deviations of the mean.

False, In a normal distribution, 95% of the data do not falls within 1 standard deviation of the mean.

The empirical rule or 68-95-99.7% rule can give us a good info about normal distribution.

This rule tells us that around 68% of the data will fall within one standard deviation of the mean, whereas around 95% will fall within two standard deviations of the mean and 99.7% will fall within three standard deviations of the mean.

Here given that, in a normal distribution, 95% of the data falls within 1 standard deviations of the mean, which is wrong because in the above description we states that, 95% will fall within two standard deviations of the mean.

So, the given statement is false.

Answer:

Step-by-step explanation:

Sum of exterior angles of any polygon =360°

Sum of exterior angles of polygon = 360°

m + 5  + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360

m + 2m + 3m + 4m + 5m + 5 + 3 + 2 + 1 + 4  = 360  {Combine like terms}

15m + 15 = 360 {Subtract 15 from both sides}

        15m = 360 - 15

        15m = 345 {Divide both sides by 15}

           m = 345/15

m = 23

m + 5 = 23 + 5 = 28°

2m + 3 = 2*23 + 3 = 46 + 3 = 49°

3m + 2 = 3*23 + 2 = 69 + 2 = 71°

4m + 1 = 4*23 + 1 = 92 + 1 = 93°

5m + 4 = 5*23 + 4 = 115 + 4 = 119°

Answer:

see explanation

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Sum the angles and equate to 360

m + 5 + 2m + 3 + 3m + 2 + 4m + 1 + 5m + 4 = 360, that is

15m + 15 = 360 ( subtract 15 from both sides )

15m = 345 ( divide both sides by 15 )

m = 23

Then

m + 5 = 23 + 5 = 28°

2m + 3 = 2(23) + 3 = 46 + 3 = 49°

3m + 2 = 3(23) + 2 = 69 + 2 = 71°

4m + 1 = 4(23) + 1 = 92 + 1 = 93°

5m + 4 = 5(23) + 4 = 115 + 4 = 119°

The average speed for the whole journey is 20 km/h.

To find the average speed for the whole journey, we can use the formula:

Average Speed = Total Distance / Total Time

In this case, the total distance for the whole journey is 40 km (20 km each way), and we need to find the total time it took for the entire journey.

For the first leg of the journey, the motorist traveled 20 km at an average speed of 15 km/h.

Using the formula Time = Distance / Speed, we can calculate the time taken as 20 km / 15 km/h = 4/3 hours.

For the return journey, the motorist traveled the same distance of 20 km but at an average speed of 30 km/h.

Again, using the formula Time = Distance / Speed, we find that the time taken is 20 km / 30 km/h = 2/3 hours.

To find the total time for the whole journey, we add the times for each leg: 4/3 hours + 2/3 hours = 6/3 hours = 2 hours.

Finally, we can calculate the average speed for the whole journey by dividing the total distance of 40 km by the total time of 2 hours:

Average Speed = 40 km / 2 hours = 20 km/h.

3. 3 “PRUEBA DE HIPÓTESIS” INTRODUCCIÓN Es evidente que las distribuciones muestrales, vistas en el capítulo anterior, basadas en la teoría de la distribución normal, desarrollan un papel de gran importancia en la inferencia estadística. La inferencia estadística comprende dos partes principales, a saber: la estimación de parámetros y la prueba o docimasia de hipótesis. En este capítulo estudiaremos la segunda de ellas, con el fin de desarrollar métodos y observar su aplicación a problemas corrientes de la vida diaria. La inferencia estadística está basada en el supuesto de tomar muchas muestras, todas con igual probabilidad de ser seleccionadas y a través de una de ellas sabremos algo acerca de la población, mediante el cálculo de estimadores, que nos permitan hacer aseveraciones, incorrectas algunas veces, estableciéndose la probabilidad de error. Este método se basa en la aplicación de técnicas de muestreo, para lo cual se requiere de un buen diseño, además de la aplicación de métodos aleatorios de selección, cuando las probabilidades son iguales para cada elemento de una población. En algunos casos no requieren ser iguales, siempre que se conozcan y sean diferentes a cero.

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- [tex]\frac{3}{2}[/tex], 0) and (x₂, y₂ ) = (0, [tex]\frac{3}{4}[/tex] )

m = [tex]\frac{\frac{3}{4}-0 }{0+\frac{3}{2} }[/tex] = [tex]\frac{\frac{3}{4} }{\frac{3}{2} }[/tex] = [tex]\frac{1}{2}[/tex] and c = [tex]\frac{3}{4}[/tex] , then

y = [tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{4}[/tex] ( multiply through  by 4 to clear the fractions )

4y = 2x + 3 ( subtract 4y from both sides )

0 = 2x - 4y + 3 , that is

2x - 4y + 3 = 0 ← equation of line

Answer:

New cost of jacket = [tex]1.2x=1.2\times 600=720\ \text{sh}[/tex]

New costs of skirt = [tex]1.2y=1.2\times 200=240\ \text{sh}[/tex]

Step-by-step explanation:

Let original cost of jacket = [tex]x[/tex]

original cost of skirt = [tex]y[/tex]

The equation will be

[tex]2x+3y=1800[/tex]

New cost of jacket = [tex]1.2x[/tex]

New costs of skirt = [tex]1.2y[/tex]

The equation will be

[tex]6(1.2x)+2(1.2y)=4800\\\Rightarrow 7.2x+2.4y=4800[/tex]

The equations are

[tex]2x+3y=1800[/tex]  [tex]\times 0.8[/tex]

[tex]7.2x+2.4y=4800[/tex]

[tex]1.6x+2.4y=1440[/tex]

[tex]7.2x+2.4y=4800[/tex]

Subtracting the above two equations we get

[tex]-5.6x=-3360\\\Rightarrow x=\dfrac{3360}{5.6}\\\Rightarrow x=600[/tex]

[tex]7.2\times 600+2.4y=4800\\\Rightarrow y=\dfrac{4800-7.2\times 600}{2.4}\\\Rightarrow y=200[/tex]

New cost of jacket = [tex]1.2x=1.2\times 600=720\ \text{sh}[/tex]

New costs of skirt = [tex]1.2y=1.2\times 200=240\ \text{sh}[/tex].

Answer:

A. The data show a negative linear relationship.

Step-by-step explanation:

According to the attached image as we can see that the temperature is in Y axis and volume of ice cubes is in X axis

So the following statements considered to be true

a. The volume represents the explanatory variable

b. Temperature would be strongly correlated to the ice cubes volume

c. As the correlation coefficient is near to -1

But it does not show the negative linear relationship

Therefore the correct option is a.
