Answer: Population , Sample
Step-by-step explanation:
In statistics, Population can be defined as the overall pool from which a statistical sample is drawn. A population may refer to an entire group of people, objects, events, hotel visits, measurements etc. While a sample is defined as a small part of a population used for statistical analysis, which is intended to show what the whole population is like.
In the case above,the population is the 7000 students in the school while the sample is the 1000 students surveyed.
Answer:
If a function has an axis of symmetry x = a,
Step-by-step explanation:
then f (x) = f (- x + 2a). The following graph is symmetric with respect to the origin. In other words, it can be rotated 180o around the origin without altering the graph. Note that if (x, y) is a point on the graph, then (- x, - y) is also a point on the graph.The graph of a quadratic function is a parabola. The axis of symmetry of a parabola is a vertical line that divides the parabola into two congruent halves. The axis of symmetry always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola.
