Question

the mean of 35,17,x, 12,42,27,38 and 22 is 22.75 find the value of x​

Answer 1

Answer:

x=-91

Step-by-step explanation:

Mean =total/no.

22.75=(35+17+x+12+42+27+38+22)/8

22.75=193+x/8

x=(22.75*8)-193

=102-193

=-91

Answer 2

$there \: \: is \: \: some \: \: mistake \: \: in \: \: the \: \: question\\ because,\: \: Solving\: \:the\: \:question\: \:gives\: \:x=-11$

Step-by-step explanation:

$Given, \: \: \: \: mean = 22.75 \\ we \: \: know \: \: that \: \: \boxed{mean = \frac{ \sum \: xi}{n} } \\ A/Q, \\ 22.75 = \frac{35 + 17 + x + 12 + 42 + 27 + 38 + 22}{8} \\ = 22.75 = \frac{193 + x}{8} \\ 22.75 \times 8 = 193 + x \\ 182 = 193 + x \\ x = 182 - 193 \\ x= - 11$
