Do males spend more time playing online games than females? A random sample of 100 males and females was selected. Let mꜰ be the population mean number of hours spent playing online games for females and let μₘ be the population mean number of hours spent playing online games for males.
How should we write the alternative hypothesis?

a) Ha: μₘ - mꜰ ≠ 0
b) Ha: μₘ- mꜰ = 0
c) Ha: μₘ- mꜰ < 0
d) Ha: μₘ- mꜰ > 0

In the diagram below, dab and dac are adjacent angles. if mdac = 25°, what is mdab in degrees? what is mbac in degrees?

Marco is studying a type of mold that grows at a fast rate. he created the function f(x) = 345(1.30)x to model the number of mold spores per week. what does the 1.30 represent? how many mold spores are there after 4 weeks? round your answer to the nearest whole number. 1.30 represents the number of mold spores marco had at the beginning of the study; 985 mold spores 1.30 represents the number of mold spores grown in a given week; 448 mold spores 1.30 represents the 30% rate of weekly growth; 345 mold spores 1.30 represents the 30% rate of weekly growth; 985 mold spores
