Answer:

n=-4

Step-by-step explanation:

( \frac{5}{3} ) {}^{2n + 1}  \times ( \frac{5}{3} ) {}^{5}  = ( \frac{5}{3} ) {}^{n + 2}

Apply Product of Power Rule

( \frac{5}{3} ) {}^{2n + 6 }  = ( \frac{5}{3} ) {}^{n + 2}

Set the exponents equal to each other

2n + 6 = n + 2

n + 6 = 2

n =  - 4

Find the LinReg line of best fit for this data set.
finlep [7]

The LinReg line of best fit for this data set is ŷ = -1.24X + 0.66

<h3>What is regression line?</h3>

A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable.

Given:

(−5, 6.3),

(−4, 5.6),

(−3, 4.8),

(−2, 3.1),

(−1, 2.5),

(0, 1.0),

(1, −1.4)

Sum of X = -14

Sum of Y = 21.9

Mean X = -2

Mean Y = 3.1286

Sum of squares (SSX) = 28

Sum of products (SP) = -34.6

Regression Equation,

ŷ = bX + a

b = SP/SSX = -34.6/28 = -1.23571

a = MY - bMX = 3.13 - (-1.24*-2) = 0.65714

ŷ = -1.23571X + 0.65714

ŷ = -1.24X + 0.66

He length of a rectangle is 7 ft more than twice the width, and the area of the rectangle is 99 ft2 . find the dimensions of the
inysia [295]
Let the width be x 

Length= x+7 

Area=lw 

99=(x+7)(x) 
99=x²+7x 
0=x²+7x-99 
x= -14.04 or x=7.04

Since a length cannot be negative, the width is 7.04 ft and the length (7.04+7)=14.07 ft

Hope I helped :)
