The mean weight of four members of the wrestling team is 160 pounds. If three of them have weights of 125, 183, and 169 pounds, then what does the fourth wrestler weigh? 159 pounds 160 pounds 163 pounds 166 pounds

The mean weight of four members of the wrestling team is 160 pounds.

Three of them have weights of 125, 183, and 169 pounds, the remaining one has weight a.

=> (a + 125 + 183 + 169)/4 = 160

=> a = 160 x 4 - 125 -183 - 169 = 163

=> Option C (163 pounds) is correct.

Hope this helps!

163

Step-by-step explanation:

Sum = mean × n

125 + 183 + 169 + X = 160 × 4

477 + X = 640

X = 640 - 477

X = 163

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
