Answer:

1. C. The managers used a cluster sample

2.  B)The managers used a systematic sample.

3. The managers used a stratified sample.

Step-by-step explanation:

1. In a cluster sampling method, the population would be divided into several small units called cluster by the researcher. Within these clusters we randomly pick one or more to observe.

2. In systematic sampling we select elements from an ordered sampling frame.

3. In stratified sampling, the population is divided into several stratas and the researcher then selects randomly to complete the sampling process

Answer:

domain is all real numberange

The addition property of equality was used to solve this equation. option A is correct.

A solution is given we have to determine the solution contains which property of equality.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
x − 5 = -14

x − 5 + 5 = -14 + 5

x = -9

We can see, in step 2 5 is added to both sides of an equality, which implies the property of additions.

Thus, the addition property of equality was used to solve this equation. option A is correct.

for these kinds of problems the outside angle always equals the opposite 2. meaning angle x=64+70 which is 134 degrees. you can double check this because all triangles equal 180 degrees. meaning that the last angle in the triangle is 46. 46+70+64=180.

so your answer is 134.

hope this helps :)

Answer:

134 Degrees.

Step-by-step explanation:

Lets figure out the third angle (y) in the triangle first.

70 + 64 + y = 180

134  + y = 180

y = 46

We now know that 46 is our third angle. Therefore, we can subtract 46 (y) from 180 (the total between x and the third angle) to get our final answer. 134 Degrees.

242

Step-by-step explanation:

   242

4/968   how many times does 4 go into 9?  2 times put the 2 above the 9

 8            4 times 2 equals 8 so you put the 8 below the 9 and subtract

  1 6                   9 minus 8 equals 1 than you drop the 6

  1 6          how many times does 4 go into 16? 4 times. put the  4 above the 6

    0 8        than multiply 4 *4 =16 than 16-16=0 drop the 8

       8          4 goes into 8, 2 times  the 2 goes above the 8. 4*2=8

        0            8-8=0

Answer:

x = 26; l = 137; m = 137

Step-by-step explanation:

If the lines are parallel, that means the measurements are too. As such, equal the two expressions together

5x + 7 = 8x - 71

add 71 to both sides

5x + 7 + 71 = 8x - 71 + 71

-71 and +71 cancel each other out

5x + 78 = 8x

subtract 5x from both sides

5x - 5x + 78 = 8x - 5x

5x - 5x cancels each other out

78 = 3x

divide both sides by 3

3x ÷ 3 = 1x which can also be written as just x

78 ÷ 3 = x

26 = x

plug in this x value into both expressions to find variables l and m

l:

5(26) + 7

130 + 7

137

m:

8(26) - 71

208 - 71

Step-by-step explanation:

Let's plug in all of the numbers: [tex]\frac{-(-2^2)(4(-3)-5(-2))}{3(4)-4(-2)}[/tex]

We get [tex]\frac{-(-4)(-12+10)}{12+8}[/tex]

Answer and explanation:

When you use positive interger to represent income, it shows that there has been an addition instead of a subtraction in money value to the business. In other words money is coming in instead of going out. Example when there is profit on goods sold say $10, it is indicated with a positive integer 10 to indicate addition in terms of operating income

When you use a negative value to represent expense, it indicates there has been a subtraction instead of an addition in money value. In other words money is going out of the business and not coming in. Example when there is a transportation expense to convey goods to the buyer, it is recorded as expenses subtracted from say revenue sales of the business. expenses are usually indicated in brackets in accounting to show negative value, although not a requirement since they are already named and recognized as expenses and subtracted regardless
