By definition, the volume of a rectangular prism is given by:
 V = (w) * (l) * (h)

 Where,
 w: width
 l: length
 h: height
 Substituting values we have:
 4x ^ 8 + 3x ^ 6 = (x) * (x) * (h)

 Rewriting we have:
 4x ^ 8 + 3x ^ 6 = x^2 * (h)

 Clearing h we have:
 h = \frac{4x ^ 8 + 3x ^ 6 }{x ^ 2}
 Then, for power properties we have:
 h = 4x ^ {8-2} + 3x ^ {6-2} h = 4x ^ {6} + 3x ^ {4}
 Answer:
 
The heigh of the box is:
 
h = 4x ^ {6} + 3x ^ {4}

Compute the least-squares regression line for predicting y from a given the following summary statistics. Round final answers to
qwelly [4]

Answer: Regression line equation:  \hat{y}=-1.008x+39.1704

Step-by-step explanation:

Equation of least-squares regression line for predicting y :

\hat{y}=b_1x+b_o

, where \text{Slope} (b_1)=r\dfrac{s_y}{s_x} ,  \text{intercept}(b_0)=\bar{y}-b_1\bar{x}

Given: \bar{x}=8.8,\ s_x=1.5,\ s_y=1.8,\ \bar{y}=30.3,\ r=-0.84

Then,

b_1=(-0.84)\dfrac{ 1.8}{ 1.5}\\\\\Rightarrow\ b_1=-1.008

Now,

b_0=30.3-(-1.008)(8.8)=30.3+8.8704\\\\\Rightarrow\ b_0=39.1704

Then, Regression line equation:  \hat{y}=-1.008x+39.1704

Mamont248 [21]

Answer:

1.54 [km²].

Step-by-step explanation:

1) the given scale is for linear functions, the given area of the lake is quadratic function. According to this

2) actual area = given area *50000 *50000;

3) the given area=0.000616 [m²],

the actual area=0.000616*50000*50000=1540000 [m²] or 1.54 [km²].
