Answer:

1,417,000

Step-by-step explanation:

Given that:

Score = 1,475,623

96% of nationwide

96% of score gives the best estimate of the number of scores below 720

0.96 * 1475623

= 1416598.08

The best estimate is 1,417,000

The temperature at a point (x, y, z) is given by T(x, y, z) = 300e−x2 − 3y2 − 7z2 where T is measured in °C and x, y, z in meter

Answer:

Rate of change $24^{\circ}$ C per meter.

Step-by-step explanation:

Given,

$T(x,y,z)=300e-x_{2}-3y_{2}-7z_{2}$

Then,

$T_{x_2}=-1, T_{y_2}=-3, T_{z_2}=-7$

Change of temperature at the point say, $(x,y,z)=(2,-1,3)$ along the direction say, $(u,v,w)=(6,-4,6)$ is,

$\Big[uT_{x_2}+vT_{y_2}+wT_{z_2}\Big]_{(x,y,z)}$

$=(6\times -1)+((-4)\times (-3))+(3\times 6)$

= $24$

Hence the rate of change of temperature is $24^{\circ}$ C per meter.
