Answer:
8/3
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
1. Distribute: -3x + 6x + 3 = x-1
2. Combine like terms: 3x + 3 = x-1
3. Subtract 3 on both sides: 3x = x-4
4. Subtract x on both sides: 2x = -4
5. Divide each side by 2: x = -2
6. Check by plugging in -2 to the equation:
Answer:
a simple random sampling.
Population is all the customers of the electronics chain store.
Step-by-step explanation:
Given that the marketing manager for an electronics chain store wants information about the ages of its customers. Over the next two weeks, at each store location, 100 randomly selected customers are given questionnaires to fill out asking for information about age, as well as about other variables of interest.
Here since these 100 customers are selected at random no groups or partitions were made.
So this cannot be stratified or cluster. Systematic sampling is done with a pre plan and here it is not mentioned. Convenience sampling is to save time the first customers or at a particular place selected. Here it is not
So this is nothing but a simple random sampling.
Population is all the customers of the electronics chain store.
Angle ADB is a right angle --- Given
Angle ADB is 90 degrees --- Definition of a Right Angle
Angle CDB is 90 degrees --- Definition of Supplementary Angles
Angle ADB = Angle CDB --- Definition of Congruent Angles
Proofs can be tricky! What helps me is thinking through them step by step and how I would prove I did something. While I'm not entirely sure what options you have for this proof, I've given my best guess.
Hope this helps!! :)
Answer:
c
Step-by-step explanation:
12 - 2 = 10
10 + 6 = 16
30 = 16 + x
x = 30 - 16
x = 14
