2. What is a line of symmetry? (1 Point)

Mathematics
1 answer:
neonofarm [45]3 years ago
8 0

Answer:

Step-by-step explanation:

I believe you're refering to an "axis of symmetry."  This is most often seen in quadratic equations.  If the parabolic graph opens up or down, the axis of symmetry is the vertical line passing through the vertex, and the graph is symmetrical about this axis.  The same applies to a parabolic graph that opens left or right.

If y = ax^2 + bx + c, the equation of the axis of symmetry is x = -b / (2a).

The frequency table shows a set of data collected by a doctor for adult patients who were diagnosed with a strain of influenza.
Alexxx [7]

Answer:

The answer would be the second plot

Step-by-step explanation:

The frequency table show how many sick patients there are in a single age range. In the first two plots, the total dots between numbers 24, 25, 26, 27, 28, and 29 add up to 3, and the other 2 plots do not, so those are not correct.

When we add up the total of dots from ages 30-34 on the first plot, there are only 4 sick patients. On the second graph, there are 6 total patients in that age range. Therefore, the dot plot that corresponds with the frequency table is the second one.
