Apply a transformation to one variable

Question 1 of 8

Calculator allowed

The explanatory variable is elevation (m), symbol h; the response variable is air pressure (hPa), symbol p. Requested operation: reciprocal of the response variable air pressure only, symbol p

The table records elevation as the explanatory variable and air pressure as the response variable

The named axis is the response axis: air pressure

air pressure (hPa)	elevation (m)
\(2\)	\(73\)
\(4\)	\(74\)
\(10\)	\(74.6\)
\(25\)	\(74.84\)

(a)1 mark

Select the one-axis operation for this table

apply the reciprocal to air pressure on the response axis only and leave elevation unchanged

apply the reciprocal to both axes, changing elevation and air pressure

apply the reciprocal to elevation on the explanatory axis only and leave air pressure unchanged

(b)2 marks

Apply the reciprocal to each blank air pressure value

air pressure (hPa)	elevation (m)	reciprocal of air pressure
\(2\)	\(73\)	?
\(4\)	\(74\)	\(0.25\)
\(10\)	\(74.6\)	\(0.1\)
\(25\)	\(74.84\)	?

\(\frac{1}{p}\) when air pressure = 2 \(\frac{1}{p}\) when air pressure = 25

Choose the label that matches the column of calculated values
