Answer:

Interval level of measurement

Step-by-step explanation:

There are four level of measurements; nominal, ordinal, interval and ratio.

Nominal level of measurements separates data into exclusive categories. There is no ranking or order required in the data. Temperature is not divided into categories.

Ordinal level of measurements separates data into exclusive categories like nominal but there is ranking and order required for the data. Temperature doe not require categories or ranking.

Interval level of measurement ranks data where there are differences between units of measure but there is no meaningful zero. For temperature, a zero is not required and the interval between values is interpret-able. For example, the distance between 67 to 67 is the same as distance between 67 to 71, 71 to 75 and 75 to 79 degree f.

A smaller square is cut from a square board. The smaller square has a side length of approximately 14 feet. What is the approxim
Oksi-84 [34.3K]

Answer:

204

Step-by-step explanation:

Find the area of the inner square. 14 x 14 = 196

Then find the area of the outer square. 20 x 20 = 400

Subtract 400 - 196 = 204

204 is closest to 200

The measures of the angles of a triangle are ∠A = (2x)°, ∠B = (x+14)°, ∠C = (x−38)° Determine the value of x. Determine A B and
nexus9112 [7]

Answer:

Step-by-step explanation:

Measures of angles are,

m∠A = (2x)°

m∠B = (x + 14)°

m∠C = (x - 38)°

By triangle sum theorem,

m∠A + m∠B + m∠C = 180°

2x + (x + 14) + (x - 38) = 180

(2x + x + x) + (14 - 38) = 180

4x - 24 = 180

4x = 204

x = 51

m∠A = 2(51)° = 102°

m∠B = (51 + 14)° = 65°

m∠C = (51 - 38)° = 13°

a) find center of mass of a solid of constant density bounded below by the paraboloid z=x^2+y^2 and above by the plane z=4.(b) F
slava [35]

Answer: x-bar = y-bar = 0 whereas z-bar = 8/3

               M= (c^2)/8 which is intern equal to 2\sqrt{2}

Step-by-step explanation:

           Find the area, by setting the limits as

               = 4\cdot \int _0^{\frac{\pi }{2}}\int _0^2\int _{r^2}^4\:rdzdrd\theta

                =4\cdot \int _0^{\frac{\pi }{2}}\int _0^2r\cdot \:4-r^3drd\theta

                =4\cdot \int _0^{\frac{\pi }{2}}4d\theta

                 =8\pi

Therefore;

Mxy=  \int _0^{2\pi }\int _0^2\int _{r^2}^4\:zrdzdrd\theta

       z-bar = 8/3

M= 8\pi dividing it into two volume gives us = 4\pi

means  4\pi =\int _0^{2\pi }\int _0^{\sqrt{c}}\int _r^c\:rdzdrd\theta

             4\pi =\left(\pi c^2-2\pi \frac{c^{\frac{3}{2}}}{3}\right)

              c=2\sqrt{2}
