Answer:
32 inches: 90 feet
Step-by-step explanation:
The question is asking for a ratio of inches to feet. Since you want the scale to be an integer, we find the lowest number to multiply 6.4 inches by to get an integer. Since 6.4 inches = 32/5, multiply by 5, leaving 32 inches. However, since you multiplied 6.4 by 5, you have to multiply 18 by 5. 6.4*5 inches: 18*5 feet, or 32 inches: 90 feet.
The median is 50, answer B. It is the middle number of the data set so it is the median. If there are an even set of numbers, so obviously there will be two numbers in the middle, then you simply need to add them and divide by two. Hope this helps! :)
