6) Stacy developed and launched a math app and a science app on the web. The following graph of m(z) = 20(2") models the number of downloads of the math app a days after the launch day. 200 180 160 140 120 100 80 60 40 20 O 1 2 3 4 5 6 7 8 9 10 Number of Days After the Launch Day The function a(z) = m(2) + 80 models the number of downloads of the science app z days after the launch day. The y-intercept for the function representing the number of downloads of the science app will be A 80 B 82 C 100 D 120 because the graph of a(z) can be created by shifting the graph of m(z) A 20 B 40 c) 60 D 80 Number of Downloads

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
