Question

5. If the mean of the data 3, 21, 25, 17, (x + 3), 19,(x - 4) is 18, find the value
of x. Using this value of x, find the mode of the data.
​

Answer 1

Answer:

18=(3+21+25+17+x+3+19+x-4)/7

18×7=84+2x

126-84=2x

42=2x

x=21

the data is :

3,21,25,17,24,19,17

so the mode of data is 17.
