1 David bought a new metal lockbox. The dimensions of his new
lockbox, in inches, are shown below. The length, width, and
height of his old lockbox are each 1/2 the length, width, and
height of the new one. Each box is a right rectangular prism.
13- height
8- width
10- length

To the nearest whole number, the volume of the new lockbox is
how many times the volume of the old lockbox?
A. 2
B. 5
C. 6
D. 7
E. 8

Can someone me and explain..will award brainlest!

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.

What is the scale factor of this dilation? a) 1/2 b) 1/3 c) 2 d) 3
