Isaiah has a bag that contains apple chews, lemon chews, and watermelon chews. He performs an experiment. Isaiah randomly removes a chew from the bag, records the result, and returns the chew to the bag. Isaiah performs the experiment 38 times. The results are shown below: An apple chew was selected 33 times. A lemon chew was selected 3 times. A watermelon chew was selected 2 times. Based on these results, express the probability that the next chew Isaiah removes from the bag will be watermelon chew as a fraction in simplest form.

Which is the correct excel formula for the 80th percentile of a distribution that is n(475, 33)? =norm.dist(80,475,33,1) =norm.inv(0.80,475,33) =norm.s.inv((80-475)/33)?

Hey free points ! people i have a few math questions on my profile consider looking at them i have to get done in 30 mins!

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?
