Answer:
The random sample is D. The other 3 cannot be taken as random since they involve groups at a specific place or doing a specific thing.
Step-by-step explanation:
Answer:y=4 x=3
Step-by-step explanation:9(-9+3y)-4y=11
-81+27y-4y=11 23y=92 y=4 x=3
Answer: Divide using synthetic division. If the remainder is 0, then x+2 is a factor.
x+2 is not a factor.
I put your question into a website, I don't know if that will help you but that's the best I can do, I don't even know the answer
Answer:
Step-by-step explanation:
Using symmetry concepts, it is found that there is a line of symmetry at x = 50, option D.
- A line symmetry is an imaginary line that runs through a graph, dividing it into two equal parts.
- A point symmetry is when every point is equidistant to the line of symmetry, but in opposite directions.
- In this problem, the values of x range from 0 to 100, being divided(definition changed) at 50, thus, there is a line of symmetry at x = 50, and option D is the correct one.
