Answer:

For every 1 inch on the drawing, it's 3 feet in real life.

Step-by-step explanation:

First, consider the length. The length is 6 inches on the drawing, while in actuality it is 18 feet. So every 6 inches represents 18 feet. Let's make a ratio; 6 : 18. To simplify it, divide both sides by 6; 6 : 18 = 1 : 3.

For every 1 inch on the drawing, it's 3 feet in real life.

Suppose an electronics manufacturer takes a sample of 5000 devices produced by an assembly line. Each device is inspected or tes

Deffense [45]

Answer:

DPMO = 40

Does not meet Six Sigma goals

Step-by-step explanation:

If there are 40 possible defects in each of the 5,000 devices, the number of defect opportunities is:

$n=5,000*40\\n=200,000\ opportunities$

If 8 total defects were found, the DPMO for the sample is:

$DPMO = \frac{8}{200,000}*1,000,000\\DPMO = 40$

Six Sigma aims to reduce defects to 3.4 Defects Per Million Opportunities, since the DPMO is higher than 3.4, the process does not meet Six Sigma goals.

PLEASE ELP ME ITS URGENT!!! 25 POINTS!!!!!<br> Write 2.4 × 1012 in standard notation.

Svet_ta [14]

Answer:

2,400,000,000,000

Step-by-step explanation:

2.4 x 10^12 means that the decimal point is moved 12 places to the right (hence the power of 12)

So by moving the decimal point 12 times you get this: 2,400,000,000,000

The reason why there are only 11 zeroes is because the 4 was a decimal place to the right of 2, thus losing a zero.

A man traveled 24 miles in 20 minutes and 18 miles in 15 minutes. Assume that the distance varies linearly with time. How far wi

Norma-Jean [14]

Step-by-step explanation:

First we need to get his speed:

speed = distance / time

If he travelled 24 miles in 20 mintues, his speed is 24 / 20 = 1.2 miles per minute

If he travelled 18 miles in 15 minutes, his speed is 18 / 15 = 1.2 miles per minute

Those two should give us the same answer since it says that the distance varies linear with time, which means that his speed is constant.

Then after 30 minutes he will have traveled: 1.2 x 30 = 36 miles
