Answer:

<em>This type of data are not measurement of anything , so it is not feasible  to calculate their average(Mean) </em>

Step-by-step explanation:T

<em>The data are at the level of measurement that are Nominal</em>

<em> In level of nominal measurement, letters, numeric and alpha-numeric, words, symbols are used to classify data in the example stated.</em>

<em> Now we recall that,</em>

<em>Brown hair = 100,</em>

<em>Blond hair = 200,</em>

<em>Black hair = 300</em>

<em>Anything else = 400</em>

<em>Thus,  100, 200, 300, 400 are used as code numbers for hair colors and does not have any importance to their  values numerically.</em>

<em>There is no arithmetic solutions such as  average, total which cannot be solved  using these numbers.</em>

<em>Therefore the average mean  calculated is not feasible</em>

Answer:

The level of measurement of the date is: nominal level of measurement.

Such data are not counts or measures of​ anything, so it makes no sense to compute their average​ (mean)

Step-by-step explanation:

The given data are at the nominal level of measurement. Nominal data is not measurable and cannot be ordered as well. It is qualitative in nature and not quantitative. For example this nominal data type can be measured of categorized as yes or no, high or low, mild, moderate or severe, male or female etc. So there is no point of calculating average of such qualitative data and nominal level of measurement deals with qualitative variables.

Ng ne Volume of a Cone
AnnyKZ [126]
Answer: height = 6, radius = 8, Volume = 401.92

Explanation:
Height = 6 given

Find radius:

Use Pythagorean’s theorem to find the side of the right triangle:

a^2 + b^2 = c^2
b^2 = c^2 - a^2
b^2 = 10^2 - 6^2
b^2 = 100-36
b^2 = 64
b = 8

And since length b is also the radius of the circle then radius = 8

Find volume:

V = pi x r^2 x h/3

V = 3.14 x 8^2 x 6/3

V = 3.14 x 64 x 2

V = 401.92

Who can do this question, I don't know how to do...this is difficult for me....who can teach me?
cupoosta [38]
We know that AB and CD are parallel.  This allows many assumptions.
From that we know that angle A and angle D are congruent. 
That means that x + 8 = 2x - 22 and we can solve for x
x + 8 = 2x - 22
x + 30 = 2x
30 = x or x = 30

We know from the figure that angle B is x or now that we solved for x is 30 degrees.  Also, we know that both angle A and angle D are 38 degrees.  Now we can solve for the vertical angle E which has a measure of y degrees.  A triangle has the sum of its angles equal to 180 degrees.

We can set up an equation like this 30 + 38 + y = 180
30 + 38 + y = 180
68 + y = 180
y = 112 degrees

That is how you would solve this problem
