You have to complete assembling a piece of machinery with various parts. each part adds to the length of the item. there are 2 parts with a length of ¾ inches, and 3 parts with a length of 1 ⅝ inches.

There  is total length of the machinery after completing the assembling a piece of machinery with various parts is

Step-by-step explanation:

Since we have given that

Number of parts = 2

Length of parts is given by

Number of parts = 3

Length of parts is given by

We need to complete assembling a piece of machinery with various parts.

According to question,

Hence, there  is total length of the machinery after completing the assembling a piece of machinery with various parts is

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
