Afitness club collected information regarding the age and gender of their members. the data is shown in the two-way frequency table below.

age 20 and under ages 21 to 30 ages 31 to 40 ages 41 to 50 ages 51 and over total
men 27 34 46 33 14 154
women 15 29 37 29 11 121
total 42 64 83 62 25 275

which trend can be concluded from the data in the given table?

regardless of gender, the percentage of members who are ages 41 and over is more than the percentage of members who ages are 30 and under.

there is a higher percentage of males who are ages 21 to 30 than females who are between the ages of 21 and 30.

fitness club membership increases with age regardless of gender.

the percentage of males who are 51 and older is the same as the percentage of females who are 51 and older.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.

step-by-step explanation:

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.

step-by-step explanation:

answer: entity is prob the answer

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
