"mean" just means arithmetic average...

(22+11+10+14+10)/5=13.4

"median" is the center term (if there is one) or the average of the two center terms in an ordered sequence...so our elements ordered are:

10,10,22,14,22   Since there is a single middle term 22, 22 is the median.

"mode" just refers to the element that occurs most in the set...10 appears twice so 10 is the mode.

tom has a cube a rectangular prism and a triangular prism. which of the shapes have more than 6 vertices?
Ierofanga [76]

Answer:

<h3>A cube</h3>

Step-by-step explanation:

Vertices of a solid shape is a point where 2 lines or edges of the shape intersects. If tom has a cube a rectangular prism and a triangular prism, then the cube has 8 vertices, a rectangular prism has 5 vertices (a rectangle has 4 vertices plus the point where all the lines coming from the vertices of the rectangle intersects).

Also, a triangular prism has 4 vertices(a triangle has 3 vertices plus the point where all the lines coming from the vertices of the triangle intersects)

Hence the only shape that has more than 6 vertices is a cube.

What is the sine value of <img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B5%20%5Cpi%20%7D%7B3%7D%20" id="TexFormula1" title=" \fr
vovikov84 [41]
Find the value of sin( \frac{5 \pi }{3} )

Rewrite as sin( \frac{6 \pi - \pi }{3} )

sin( \frac{6}{3} \pi -  \frac{ \pi }{3}  )

sin(2 \pi - \frac{ \pi }{3} )

since sin(π/3) = √3/2

and sin(π-α) = -sinα

α is sin(π/3) of course

-sin( \frac{ \pi }{3} )

- \frac{ \sqrt{3} }{2}
