Answer:

Yes it is.

Step-by-step explanation:

No matter how you rearrange the addition expressions on either side, it will always equate to be the same answer. This is because of the commutative property of addition, which states that a+b=b+a. That is the case in this problem, soooooo yeah.

An engineer wants to obtain a random sample of the output from a process manufacturing digital cameras. The process operates 16
Troyanec [42]

Answer:

Non-Random Sample

Step-by-step explanation:

A sample in which each element has an equal chance of being selected is known as a random sample. Otherwise, a sample is said to be a non - random sample.

An engineer selects five cameras on Monday, Tuesday, and Wednesday at random between 3 pm and 4 pm each day. So, the cameras that are not in the process of production between 3 pm and 4 pm have no chances of being selected.

So, each camera does not have an equal chance of being selected.

This is an example of a non - random sample.

What is 65% written as a fraction in simplest form
frosja888 [35]
65% divided by 100% = 0.65

0.65 is 65/100

65/100 in simplest form is 13/20

  65 is divided by 5 to arrive at 13
100 is divided by 5 to arrive at 20

13/20 is the simplest form of 65% because both numbers, 13 and 20, no longer have a common factor left.

A six person committee is chosen at from a group of 12 people. How many different committees are possible?
Stells [14]
Since order does not matter, ie Joe, Jim, and Dave is the same as say Jim, Dave, and Joe.  You would use the "n choose k" formula for unique combinations...

n!/(k!(n-k)!), where n=number of possible selections and k=selections made...

12!/(6!(12-6)!)

12!/(6!6!)

924

So there are 924 possible different committees of six people from a pool of twelve people.

What is the measure of QPR
Katarina [22]

Answer:

The answer I got was 86.

Step-by-step explanation:

This is called the central angle theorem. This means that the central angle, which in this case is QOR (let the origin (middle) be O), is twice the size of the inscribed angle, which is QPR.

That means: 2 x  QPR = QOR

→ 2 * (x-33) = x + 20

→ 2x - 66 = x + 20

Collect the like terms

→ 2x - x = 20 + 66

x = 86
