The mean will change, the median will stay the same.

Step-by-step explanation:

The mean will increase because that is the average and a gain of 1000 kg will increase that average.

The median will not change.   The median is the middle point.  That was the highest point before and increasing it will not change that it was the highest point.

C

Step-by-step explanation:

When the last value changes (but its still at the same position), the median remains unchanged

On the other hand, since the data value has increased, the sum of all values will also increase, thereby increasing the mean

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2
