Which steps would you use to solve this equation? p+7=12
We can solve this equation in one step only, and this is the step:-
Subtract 7 from both sides
p=12-7
p=5
<h3>Good luck.</h3>

Answer:
The type of sampling used is the Cluster sampling technique.
Step-by-step explanation:
- Random Sampling
In random sampling, each passenger would have an equal chance of being surveyed. If this particular scenario wanted to use random sampling, they would have used computer generated random passenger numbers and surveyed them, not just passengers all on the same bus picked randomly.
- Systematic sampling is easier than random sampling. In systematic sampling, a particular number, n, is counted repeatedly and each of the nth passengers is picked to be sampled.
- Convenience Sampling
This is the worst sampling technique. It is also the easiest. In Convenience sampling, the surveyor just surveys the first set of passengers that they find.
- Stratified Sampling
Stratified sampling divides the population into groups called strata. A sample is taken from each of these strata using either random, systematic, or convenience sampling.
- Cluster sampling
Cluster Sampling divides the population into groups which are called clusters or blocks (the different buses). The clusters are selected randomly, and every element in the selected clusters is surveyed (each passenger on the selected buses, is surveyed!). Evidently the answer to the question!
The trick is to write appropriate equations and then solve the system of equations you've created.
"sum of two numbers is -5:" x + y = -5
"difference is -1:" x-y = -1
Add these two equations together. This will cause y to drop out, and you will be left with an equation in x alone:
2x = - 6, so x = -3. Subst. -3 for x in either equation, above, and find the corresponding y value.
Then write your solution as (-3, y ) (write in your value for y).
Answer:
The correct option is 4.
Step-by-step explanation:
It is given that figure ABCD is transformed to figure A′B′C′D′.
The vertices of ABCD are A(1,1), B(3,3), C(4,2) and D(4,1).
The vertices of A'B'C'D' are A'(1,-3), B'(3,-1), C'(4,-2) and D'(4,-3).
It is clear that the figure translate 4 units down and the rule of translation is
Translation is a rigid transformation, it means image and preimge are congruent.
Since ABCD is translate 4 units down to make A′B′C′D′, therefore
Congruent part of congruent figures are congruent.
Therefore the correct option is 4.
I Hope It's Helpful :)
