I am doing a portfolio on the effects of stricter gun laws on gun deaths. I have data from 4 different states on mass murder incidents, homicides, mortality rate, and population. I now need to choose a statistical test (z-test, t-test, etc) to use on this data. Which test do I use on each category? (They can all use the same one, different ones, or multiple.)

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

-4, -2, 1, 4

step-by-step explanation:

domain = x values

range = y values

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
