Jenna used a probability simulator to roll a 12-sided number cube 100 times. her results are shown in the table below: number on the cube number of times rolled 1 14 2 12 3 10 4 5 5 16 6 5 7 8 8 18 9 2 10 5 11 2 12 3 using jenna's simulation, what is the frequency of rolling a 1 on the number cube? 100 over 86 100 over 14 86 over 100 14 over 100

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.

Can someone me with #s 8, 9, and 11. with just one of the three also works. prove using only trig identities.

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
