1. The product of a number and four more than the number is 12 find the two numbers 2. The length of rectangle is 1 cm less than three times the width. If the are of the rectangle is 30 cm^2, find the dimensions of the rectangle

3. You throw a rock straight up form a cliff that was 24 ft above the water. If the weight of the rock, h, in feet, after t seconds is given by the equation h =-16t^2+20t+24, how long will it take for the rock to hit the water? (hint: set h to 0 and solve with the quadratic formula)

both the histogram and the stem and leaf plot will visually show how many shoppers were of various ages within each range of data.   the histogram does not give us the specific ages of these shoppers unlike the stem and leaf plot.a histogram does not give us a true range of the data because we do not know exactly how old the shoppers were. a stem and leaf plot will give exact ages, so we can determine the exact range along with all measures of center and the others measures of center.   with the histogram, we cannot find any of these.
