This is an inequality.
This is what the statement should look like:
Now, you can actually "properly" reverse these meaning the equality sign changes too. So basically you can mirror them.
The "mirrored" inequality expression would look like this:
Now just like normal algebra, you can transpose these terms from 1 side to another and so, -8 would transpose to the right hand side and the operation would be the inverse or in this case, addition. The expression would look something like this:
Add them up and you get: :D
He has 24 meals that use milk in 8 days. If he finished 2 gallons in 24 sittings, he uses 2/24 of a gallon a day which simplifies to 1/12 gallon a day.
Answer:
(0,2) is one solution of the solution set of the equation x + 3y = 6.
(0,2) is not an element of the solution set of the equation -x + y = 8.
Step-by-step explanation:
We have the system of equations, x + 3y = 6 and - x + y = 8.
Now, we have to check whether the solution set for that system of equations or not includes the point (0,2) or not.
Here, the equation x + 3y = 6 is satisfied by the point (0,2).
Hence, (0,2) is one solution of the solution set of the equation x + 3y = 6.
But the equation - x + y = 8 is not satisfied by the point (0,2).
So, (0,2) is not an element of the solution set of the equation -x + y = 8.
Answer:
d=8
Step-by-step explanation:
Okay we've got 68/17 and d/2
68/17 = 4 meaning d/2 is also 4. Since 4 × 2 is 8, we know the answer is 8.
Answer:
Convenience sampling.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Systematic sampling.
3. Stratified sampling.
4. Cluster sampling.
5. Quota sampling.
6. Convenience (opportunity) sampling.
Convenience sample can be defined as a sampling technique in which the representatives to be used are easily accessible. For example, a researcher using a social media poll such as Twitter polls.
In this scenario, Catherine Chao, Director of Marketing Research, chooses thirty-six of her closest friends to participate in the testing of a new toothpaste package. Thus, Catherine's sample is a convenience sampling.
