One example is when n is 11. 11^2 + 4 = 125. 11 is odd but the 11th term of the sequence, 125, is not prime because 125 is divisible by 5 and 25.
the probability would be 100% if your smart
Step-by-step explanation:
ok so think of this if you have 10 marbles but it never said anything about getting rid of marbles ,you can get rid of four marbles.
Domain of f(x) = √6 - 2x is {x | -∞ < x ≤ 3}
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.
We can employ a simple repeated decimal trick:



###
Alternatively, we can compute the partial sum of the series.





As
, the second term vanishes and we're left with
. Notice that this is really just a more formal version of the earlier trick.
