A candy machine can make 25.15 pounds of candy in an hour. How much candy can it make in 6.5 hours?

Answer:

Yes. Her sample is unrepresentative of the population in her community.

Step-by-step explanation:

a) Data and Calculations:

Population                Study  Census %     Representative       Over/Under

                               Sample                           Sample              Representation

Whites                       300        48%           288 (48% * 600)         12

African Americans      80         12%             72 (12% * 600)           8

Latinos                       100         18%           108 (18% * 600)           (8)

Asians                         40          9%             54 (9% * 600)           (14)

Others                        80         13%             78 (13% * 600)            2

Total                         600      100%          600                                0

b) There is selection bias in her sample. A representative sample of 600 is the subset of a population that seeks to accurately reflect the characteristics of the larger group.   When the sample for each category does not accurately represent the characteristics or attributes of the population categories, then it is unrepresentative.

Sampling is the collection of randomly chosen data from the entire population to come to an end conclusion about the variable to be determined or known.

Yes, the sample is unrepresentative of the entire population.

The reason for the sample being unrepresentative of the entire population in her community is that the selected sample is deviating a lot from the population count.

As per the computation, there is selection bias in her sample. This is because the representative sample is 600 that represents the entire population and reflects the characteristics of the larger group.

The sample becomes unrepresentative when the sample chosen does not accurately represent the true attributes of the population.

Answer:

The measure of the other angle is 66°.

Step-by-step explanation:

Given that the total angles in a triangle is 180° so in order to find the other angles, you have to subtract :

90° + 24° + θ = 360°

114° + θ = 180°

θ = 66°

Answer:

Coordinates of point A are

(-3,-2)

Origin lies in the center of coordinate system. That means that you can picture this as right triangle with sides 3 and 2 and you need to find hypotenuse of it.

Using pythagoras theorem we calculate:

h^2 = 3^2 + 2^2 = 13

h = sqrt 13

Answer:

Least no of packs = 120

Step-by-step explanation:

Given that,

Plastic plates come in packs of 8, plastic utensils come in packs of 12, and plastic cups come in packs of 20.

We need to find least numbers of packs you should buy in order to have the same number of plates, utensils, and cups.

It means we need to find the LCM of 8,12,20

Prime factorisation of 8 = 2×2×2

Prime factorisation of 12 = 2×3×2

Prime factorisation of 20=2×5×2

LCM = 120

Hence, there are 120 least number of packs you should buy in order to have the same number of plates, utensils, and cups

Given :

Salt is poured from a container at 10 cm³ s-¹ and it formed a conical pile whose height at any time is 1/5 the radius of the above.

To Find :

At what rate is the height of the cone increasing when the height is 2 cm form the base of the cone.

Solution :

We know, volume of a cone is given by :

[tex]V = \dfrac{\pi r^2h}{3}[/tex]

Also, h = r/5

r = 5h

[tex]V = \dfrac{\pi (5h)^2h}{3}\\\\V = \dfrac{\pi 25h^3}{3}[/tex]

Differentiating above equation w.r.t h, we get :

[tex]\dfrac{dV}{dt} = \dfrac{d}{dt}(\dfrac{\pi 25h^3}{3})\\\\\dfrac{dV}{dh} = 25\pi h^2\dfrac{dh}{dt}\\\\\dfrac{dh}{dt}= \dfrac{\dfrac{dV}{dh}}{25\pi h^2 }\\\\\dfrac{dh}{dt}=\dfrac{10}{25\times 3.14\times 2^2}\\\\\dfrac{dh}{dt}=0.032\ cm/s[/tex]
