4n-40=7(-2n+2)

4n-40=-14n+14

subtract -4n from both sides

-40 = -18n +14

subtract -14 from both sides

-54=-18n

divide both sides by -18

Find the value of the linear correlation coefficient r. Round to 3 decimal places. (47, 8), (46, 10), (27, 10)
Mnenie [13.5K]

Answer:

- 0.5379

Step-by-step explanation:

Given the data below :

(47, 8), (46, 10), (27, 10)

X:

47

46

27

Y:

8

10

10

Using the functionality of the correl() function in excel, which takes in the x and y values of a data. The value of correlation Coefficient (r) obtained is - 0.5379 which indicates that a fairly strong negative correlation exists between the x and y variables. As the the strength of correlation depends on how close the Coefficient is to 1 (strong) or 0 ( weak). Negative value indicates that an increase in the value of one variable leads to a decrease on the value of the other.

A programmer wants to display how the shape of a rectangle with a fixed perimeter of 375 inches can be changed by varying the re
Nina [5.8K]

Answer:

A = 187.5L - L^2

So,

g(l) = 187.5l - l^2

Step-by-step explanation:

The perimeter of a rectangle is given by:

P = 2(L + B)

Where P = perimeter

L = Length

B = Width

Making B the subject of formula, we have;

B = P/2 - L ......1

The area of a rectangle is:

A = L × B ........2

Substituting equation 1 to 2.

A = L × (P/2 - L)

A = LP/2 - L^2 .......3

Given that the perimeter P = 375 inches

A = L(375)/2 - L^2

A = 187.5L - L^2

So,

g(l) = 187.5l - l^2
