Answer:

a) Qualitative

b) Qualitative

c) Quantitative

d) Quantitative

Step-by-step explanation:

A variable is quantitative if it assumes numerical values, for example 1,2,3.

If it assumes "labels", for example good or bad, it is qualitative.

(a) The occupation of your neighbors. Answer:

Labels. Teacher, trainer, athlete, ...

So it is qualitative

(b) The martial status of your coworkers. Answer:

Labels: Married, single,..

So it is qualitative

(c) Your college GPA. Answer:

Numeric, 2,3,...

So it is quantitative

(d) The amount of bacteria on a piece of moldy bread

Numeric, 0.5mm, etc

So it is quantitative

A steel pipe is being carried down a hallway 9 ft wide. At the end of the hall there is a right-angled turn into a narrower hall
Rudiy27

Answer:

21.62m

Step-by-step explanation:

first draw the the pipe

second you need know wich is the angle between the pipe and the corner

β=Tan^-1(6/9)=33.7

find the components using tow triangles

a=9/cos(33.7)=10.81m

b=6/sen(33.7)=10.81m

finally sum the leghts

L=10.81+10.81=21.62mm

The sum of three consecutive even numbers is one hundred sixty-two. What is the smallest of the three numbers?
zepelin [54]
Since the numbers are consecutive, they must be near each other in size, and therefore near one-third of 168. And since the lower number is -2 off the middle, and the upper number is +2 from the middle, the middle number must be exactly one-third of 168—otherwise the sum of the three could never be 168. Labelling the three consecutive numbers as x, y, and z:

x + y + z = 168

(y-2) + y + (y+2) = 168.

3y = 168

y = 56

therefore the smallest number (x) = 54.
