9. The table below lists all 50 states in the United States of America and their 2015 violent crime rates. This rate measures the number of violent crimes in a state per 10,000 people. For instance, if a state had 12,000 violent crimes and a population size 2,300,000, its violent crime rate was (2,300,000) × 10,000 = 52. a. C. e. i. f. g. h.

Opinions are split about a coffee​ company's pumpkin-flavored coffee​ (PFC). Yet every year over the last five years the consumption of​ pumpkin-flavored goods has increased. If we look at the​ numbers, it also becomes clear why a leading coffee company keeps offering the PFC earlier and earlier every year. According to a​ magazine, the amount spent by PFC buyers at the coffee company is about​ 17% higher than​ non-PFC buyers. The accompanying table shows a random sample of eight​ consumers, the amount they spend per​ week, and the number of PFCs purchased per week. PFC Spending     2 13.88     7 39.11     4 19.79     1 9.84     3 15.43     1 21.52     5 37.39     3 13.85   The slope is b1=4.465 The​ y-intercept is b0=6.840   Because the slope is positive, it can be concluded that one extra PFC purchase per week will increase the average amount of spending per week by 4.46 dollars.     Predict…

An interdepartmental task force is being formed to investigate an increase in violent crimes. 1/5 of the task force will be police officers from the local precinct. 1/4 will be ATF agents, and the remaining 22 will be from the FBI. How many people are participating in the task force?
