Let x be the weight of David so
x+16-25+4 = 177
x-5=177
x= 177+5= 182 pound
Answer:
so for the mean u add all the numbers on there and then divide it by 5 since there are 5 numbers on there so 78+84+100+78+81=421 now we divide 421 by 5 so 421÷5= 84!
now the median would be 100? and the mode is 78 since 78 is the number that showed the most!
