A.) 200cm
B.) 206cm
A explanation.) To find the mean, you add all the heights and divide by 5 (how many numbers there are), this gives you 1000 divided by 5, which equals exactly 200cm.
B explanation.) I tried the equation with numbers higher than 202, going up one each time, and 206 was the one that equaled exactly 201.
Step-by-step explanationdomain and range of 1/(4-9x) is second one.
