Given the explicit expression f(n)=5n−2, write a set showing the sequence, and write a recursive expression. (1 point) A {3, 8, 13, 18,...}, f(1)=3 and f(n)=f(n−1)+4 for n>1

B {3, 8, 13, 18,...}, f(1)=3 and f(n)=f(n−1)+5 for n>1

C {5, 10, 15, 20,...}, f(1)=5 and f(n)=f(n−1)+5 for n>1

D {5, 10, 15, 20,...}, f(1)=5 and f(n)=f(n−1)+4 for n>1

Find the slope and the y-intercept if there's one and the equation of the line given these two points( 3, 2) and( 3, -4)

(b) suppose that consolidated power decides to use a level of significance of α = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is x⎯⎯ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume σ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
