4u-24 because you have to take 4 and multiply it by your things inside your parentheses
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.

Answer: 4(7-u)
Step-by-step explanation:
In order to factor, you have to find the GCF (Greatest Common Factor)
28:1, 28, 2, 14, 4, 7
4:1, 4, 2
The greatest common factor here is 4.
You can factor out 4 from this equation, therefore making it 4(7-u)
Let a ault tickets and s student tickets be sold.
a+s=56
13a+8s=568
s=56-a
13a+8(56-a)=568
13a+448-8a=568
5a+448=568
5a=120
a=24
s=56-24=32
24 adult tickets and 32 student tickets are sold.
