These two lines create vertical angles, which are congruent. That means angle z = 60 degrees. Since angle z and the angle represented by the expression 6x + 60 are supplementary (they are adjacent angles that add to equal 180 degrees), you can set up the following equation to find x:

6x + 60 + 60 = 180
6x + 120 = 180
6x = 60
x = 10

Answers:
x = 10
z = 60

The owner of a large restaurant is considering a new “no tipping” policy and wants to survey a sample of employees. The policy w
Stolb23 [73]

A) The strata to be used in this survey by the employer is; <em><u>Type of Staff</u></em>

B) <em>Stratified Random Sampling</em> will be preferred because the opinions of <em><u>the staffs on the tipping policy</u></em> may be the same within each type but differ across the different <u><em>types of staffs.</em></u>

  • A stratified random sampling is a type of sampling that divides a population into groups known as strata.

Now, from the question, we see that after adding a 20% to the cost of food and beverages, that the additional revenue will be distributed equally among the kitchen and server staffs.

This means the strata here will be the type of staff because the opinions of the staffs on the tipping policy may be the within each type but differ across both types of staffs.

What is the length of the missing base of the trapezoid?
Eddi Din [679]

Answer:

6 inches

Step-by-step explanation:

Area = (base1 + base2)/2 · height

base1 = b

base2= 8

height = 3

Area = 21

21 = (b+8)/2 ·3

21 = 3(b+8)/2

multiply both sides by 2

42 = 3(b+8)

divide both sides by 3

14 = b+8

subtract 8 from both sides

b = 6 in
