Answer:

Step-by-step explanation:

Faces is essentially the number of sides. In an easier shape like this you could just count the number of sides. You would have 5 faces in this shape.

On a side note, when dealing with convex polyhedrons(you might not have gotten into this) you can find the number of edges by by adding the number of vertices, plus the number of vertices, minus 2.

For example, lets take a cube. The cube has 6 faces and 8 vertices. 6 + 8 - 2 = 12 edges

Answer:

Data set 3 has the highest IQR, so the correct option is {13,17,12,21, 18,20}

Step-by-step explanation:

The question is:

Which data set has the greatest spread for the middle 50% of its data

We have given the data sets:

{18,13,22, 17, 21, 24}

{17,19,22,26,17,14}

{13,17,12,21, 18,20}

{18,21,16,22,24,15}

To find the greatest spread for the middle we need to find the IQR for all the data sets and check which one is highest.

So,

For the first set: 22-17 = 5

For the second: 22-17 = 5

For the third set = 20-13 = 7

For the fourth set = 22-16 = 6

Since data set 3 has the highest IQR, so the correct option is {13,17,12,21, 18,20} ....

Solve for x of (8x+30)°(4x+18)°

rodikova [14]

$(8x+30) ^{o}+(4x+18)^{o} =180^{o}\\ \\ 8x+30 ^{o}+ 4x+18 ^{o} =180^{o}\\ \\12x +48^{o}=180^{o} \ \ |-48^{o}\\ \\12x +48^{o}-48^{o}=180^{o}-48^{o}\\ \\12x= 132^{o}\ \ /:12\\ \\x=\frac{132^{o}}{12}\\ \\x=11^{o} \\ \\ \\ Answer : C. 11$
