Perimeter is adding all the sides together.

2(3x+12) accounts for 2 of the longer sides.

2(5x+9) accounts for 2 of the shorter sides.

The perimeter equation can be...

2(3x+12) + 2(5x+9)

You can further simplify this by distributing the 2 to each bracket.

6x+24 + 10x+18

Add like terms.

16x + 42 is the equation for the perimeter.

Plastic parts produced by an injection-molding operation are checked for conformance to specifications. Each tool contains 10 cavities in which parts are produced, and these parts fall into a conveyor when the press opens. An inspector chooses 2 part(s) from among the 10 at random. Two cavities are affected by a temperature malfunction that results in parts that do not conform to specifications.
a. How many samples contain exactly 1 nonconforming part?
b. How many samples contain at least 1 nonconforming part?

Answers

Answer:

16 ;

17

Step-by-step explanation:

Number of cavities = 10

Number of parts chosen = 2

Number of cavities affected by temperature malfunction = 2

A.)

Number of samples that contain exactly one conforming part :

2C1 * 10-2C2-1

2C1 * 8C1

Combination formula :

nCr = n! ÷ (n-r)! r!

Using calculator :

2C1 * 8C1 = 2 * 8 = 16

B)

b. How many samples contain at least 1 nonconforming part?

10C2 - 8C2 = 45 - 28 = 17

Answers

Answer:

40

Step-by-step explanation:

A rhombus diagonals form perpendicular angles. It also bisects and form 4 right triangles. Looking at triangle MAS, we can use pythagorean theorem to find the side MA.

[tex]ms {}^{2} + sa {}^{2} = {ma}^{2} [/tex]

ms=6, sa =8 so we plug that in.

[tex]6 {}^{2} + {8}^{2} = ma {}^{2} [/tex]

Simplify

[tex]36 + 64 = ma {}^{2} [/tex]

[tex]100 = ma {}^{2} [/tex]

take sqr root

[tex] \sqrt{100} = ma[/tex]

[tex]ma = 10[/tex]

Now let find the perimeter

Since perimeter of a Rhombus is 4a where a is the length of a side. We plug it in

[tex]4(10) = 40[/tex]

The answer is 40

Equipped with confidence that no camera would be able to identify him (due to smearing his face with lemon juice), he boldly robbed two banks in Pittsburgh without using a disguise.
