Answer:
Negative
Step-by-step explanation:
From the scatter plot displayed, we could clearly observe the direction of the trend line as it produces a negative slope. For high values of y, the values of x are low and similarly, high values of x have low y values. Therefore, this kind of relationship between the two variables is considered negative.

Answer:
0.2kN
Step-by-step explanation:
An hydraulic jack works by the principle that pressure applied to one part in an enclosed liquid is transmitted equally in all parts of the liquid. this is in accordance with Pascal's principle.
Pressure= Force/Area
P=F/A
Pressure due to the load= Pressure due to input force for the system to be in balance.
Let force due to load be F₁, input force be F₂, Area at the load piston be A₁ and the area of the pipe through which the input force transmits be A₂, then,
F₁/A₁=F₂/A₂
10000N/5m²=F₂/1m²
F₂=(1000N×1m²)/5m²
F₂=200N
=0.2kN
