Answer:

see below

Step-by-step explanation:

Each vertex has a single-letter label.

Each edge joins two vertices, and is named by naming those two vertices.

Each polygon is named by listing the vertices at its corners. It is a plane figure.

The base is the polygon opposite the point where all of the triangles come together.

16. figure: pentagonal pyramid ABCDEF

17. base: ABCDE

18. faces: ABF, BCF, CDF, DEF, AEF, ABCDE (the bottom face, or base)

19. edges: AB, BC, CD, DE, AE, FA, BF, CF, DF, EF

20. vertices: A, B, C, D, E, F

Answer:

The probability of assembling the product between 7 to 9 minutes is 0.50.

Step-by-step explanation:

Let X = assembling time for a product.

Since the random variable is defined for time interval the variable X is continuously distributed.

It is provided that the random variable X is Uniformly distributed with parameters a = 6 minutes and b = 10 minutes.

The probability density function of a continuous Uniform distribution is:

$f_{X}(x)=\left \{ {{\frac{1}{b-a};\ a$

Compute the probability of assembling the product between 7 to 9 minutes as follows:

$P(7$

$=\frac{1}{4}\times \int\limits^{9}_{7}{1}\, dx$

$=\frac{1}{4}\times [x]^{9}_{7}\\$

$=\frac{1}{4}\times (9-7)\\$

$=\frac{1}{2}\\=0.50$

Thus, the probability of assembling the product between 7 to 9 minutes is 0.50.
