Answer:
a) The percentage of adults who smoke are decreasing with time. b) the equation that best described this data is y=-0.3364x+22.809 (R^2=0.859) in which y is the percentage of adults who smoke and x the number of years. c) the percentage of adults who smoke will be 19.8% and it will not meet the expected 12%, it would take 32 years to reach that value.
Step-by-step explanation:
The data can be plotted to which years is the independent variable and percentage of adults who smoke is the dependent variable. The linear trendline that described this data has a negative slope which indicates that the percentage of adults is decreasing with time. In order to determine if the OSH target is being met, the x is replaced by 9 which is the goal period of nine years. The y is 19% which is higher than the 12% goal. In order to know the period it will take to the reach the goal of 12%, the y is replaced by 12 in the curve and the x is the answer in years = 32 years.
Answer:15 2/5
Step-by-step explanation:
23 - 7 = 16
16 - 3/5 → 15 5/5 - 3/5 = 15 2/5
I think it’s B. 7.50+1.50x<_15
1/8
50% is the same as 1/2, so you just multiply 1/2 by 1/4 to get the answer. First, multiply the numerators. 1*1 is 1. Then, multiply the denominators. 2*4 is 8. So, your answer is 1/8. If you want to check this, multiply 1/8 by 2 and you will get 1/4.
