a man and her daughter , Benedicta have a meeting at a given location. Both of them can arrive at the meeting place with a delay between 0 and 1 hour. The first person who has arrived will wait for 20 minutes and will leave if the other fails to show up. Calculate the probability that Benedicta will actually meet her dad.

Which shows the correct solution of the equation 1/2a+2/3b=50, when b=30?

When you answer this can you explain

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?
