A small plane is flying a banner in the shape of a rectangle. The area of the banner is 144 square feet . The width of the banne
Margarita [4]

Answer:

The answer to your question is width = 6 ft; length = 24 ft

Step-by-step explanation:

Data

Area = 144 ft²

width = w

length = l

The width is 1/4 of the length

Formula

Area = width x length = w x l

Length = 4 width     l = 4w

Process

1.- Substitute length in the first equation

                       Area = w(4w)

Simplify

                       Area = 4w²

2.- Solve for w

                      w = \sqrt{\frac{Area}{4}}

Substitution

                      w = \sqrt{\frac{144}{4}}

Simplification

                      w = \sqrt{36}

Result

                      w = 6 ft

3.- Find l

                       l = 4(6)

                       l = 24 ft

The relationship between two variables partialling out the effect that a third variable has on one of those variables can be exp
TiliK225 [7]

Answer: partial correlation.

Explanation:

partial correlation measures the degree of association between two random variables, with the effect of a set of controlling random variables removed. If we are interested in finding to what extent there is a numerical relationship between two variables of interest, using their correlation coefficient will give misleading results if there is another, confounding, variable that is numerically related to both variables of interest. This misleading information can be avoided by controlling for the confounding variable, which is done by computing the partial correlation coefficient.
