Answer: 108 cubic inches

Step-by-step explanation:

Hi, to answer this question we have to apple the next formula:

Volume of a rectangular prism (V): base area x height (deep of the soil)

Replacing with the values given:

V = 36 x 3 =108 cubic inches

Ian should put 108 cubic inches of soil in the flower pot.

The volume of the soil is 108 cubic inches.

A Biology student who created a regression model to use a bird's Height when perched for predicting its Wingspan made the follo

xxTIMURxx [149]

Answer:

(A) A scatter plot is used to determine if the linear model is appropriate.

(B) A linear model estimates the value of the dependent variables.

Step-by-step explanation:

The regression model is formed to estimate the Wingspan using the bird's Height when perched.

The model is of the form:

$Wingspan=\beta Bird's\ height\ + \alpha +\epsilon$

(A)

The R squared value is a statistic that is used to determine the proportion of variation in the dependent variable that can be explained by the independent variables.

R squared value of 93% indicates that 93% variation in the Wingspan is explained y the bird's height when perched.

To determine whether the linear model is appropriate one could use a scatter plot. A scatter plot is used to determine whether the provided data is representing the linear relation between two variables.

(B)

The regression model is:

$Wingspan=\beta Bird's\ height\ + \alpha +\epsilon$

This model is used to estimate the wingspan for any provided bird's height.

It does provided an accurate value of the dependent variable.

Thus, a bird with height 10 inches can have an estimated wingspan of 17 inches.

Show that if x, y, z are integers such that x^3+5y^3 = 25z^3, then x = y = 0.

Gre4nikov [31]

Answer:

3125*k^9 + y^3 is an integer my closure property.

but 5^(1/3) is not an integer, which forces z to be irrational.

Note that there is no way an integer value can rationalize 5^(1/3)

Step-by-step explanation:

x^3 = 25z^3 - 5y^3

x^3 = 5 ( 5z^3 - y^3)

x = (5 ( 5z^3 - y^3) )^(1/3) must be an integer

= 5^(1/3) * (5z^3 - y^3)^(1/3)

Then (5z^3 - y^3)^(1/3) = 25*k^3 for some integer k

5z^3 - y^3 = 15625*k^9

5z^3 = 15625*k^9 + y^3

z^3 = 3125*k^9 + (1/5)*y^3

z = ( 3125*k^9 + (1/5)*y^3 )^ ( 1/3)
