Do all three of these interpretations state the parameter in terms of the "mean response of all individuals in the population?" no yes

(b) A swimming pool is being filled. At the deepest point, the depth of the water in the pool at any instant is \( h \mathrm{~m} \). The volume of water in the pool \( V \mathrm{~m}^{3} \) is given by \[ V(h)=20 h^{2}+40 h \] Find the rate at which the volume of water is changing with respect to the depth when th water in the pool is 0.75 m deep.

In general, what is \( \mu \) ? The mean of a sample of data. The mean response of all individuals in a population. The values of the response variable for all individuals in a population.

QUESTION THREE (a) Find the \( x \)-coordinate of the point on the graph of the function \( f(x)=4 x- \) where the gradient is equal to 10 .

A 4.90 kg ball is on a hill that is inclined at \( 18.0^{\circ} \). What is the \( x \)-component of the weight of the ball? \[ w_{x}=[?] \mathrm{N} \]

Use the distributive property to evaluate \( 4(2 x-1) \) when \( x=5 \). 32 39 46 36
