Simple random sampling
Step-by-step explanation:
Hope this work :)
Answer:
B :step 2 she didnt collect all the like terms and calculate
Step-by-step explanation:
first rewrite remove all ( )Parentheses
2nd collect all like terms and calculate
a^4 + 7a -16 -12^a^3 + 5a -3
a^4 + 12a - 19 - 12a^3 ( Like terms are 7a +5a and -16 +-3)
so she skipped the second step
The first thing we must do in this case is to rewrite the length of the first tape.
We have then:
4/8 = 2/4 = 1/2 = 3/6 yard
Therefore, since the tapes have the same length, the following measure is NOT possible:
4/6 yard
Answer:
A. 4/6 yard
The graph is not a direct variation because the line does not go through the origin; option C.
<h3>What is a direct variation?</h3>
A direct variation is a relationship between two or more quantities in which as one quantity increases, the other quantity also increases. Similarly, if the other quantity decreases, the other decreases as well.
For the graph of a direct variation, the line must pass through the origin.
Therefore, the graph does not represent a direct variation because the line does not go through the origin.
In conclusion, direct variation involves a corresponding increase or decrease in two related quantities.
