Answer:

5.1

Step-by-step explanation:

a² + b² = c²

1² + 5² = c²

1 + 25 = c²

26 = c²

c = 5.1

The equation 2(m-8)+3=17 has more than one solution method. Give at least two different "first steps" to solve this equation.

Troyanec [42]

1. you could distribute the 2 which would give you 2m - 16 + 3 = 17
2. You could add the 2 and 3 together and the problem would be 5(m - 8) = 17

Estimate the line of best fit using two points on the line 100 90 80 70 (e, 80) 60 30 20 10 (2.20) 10 O A. y= 2x O B. y = 2x+10

nexus9112 [7]

Answer:

$y = 10x$

Step-by-step explanation:

Given

The attached plot

Required

The line of the best fit using $(8,80)$ and $(2,20)$

We have:

$(x_1,y_1) = (8,80)$

$(x_2,y_2) = (2,20)$

Calculate slope (m)

$m = \frac{y_2 - y_1}{x_2 - x_1}$

$m = \frac{20 - 80}{2- 8}$

$m = \frac{-60}{-6}$

$m = 10$

The equation is then calculated using:

$y = m(x - x_1) + y_1$

$y = 10(x - 8) + 80$

Expand

$y = 10x - 80 + 80$

$y = 10x$

High population density can cause increased competition for resources such as food or shelter, while a low population density ca

krek1111 [17]

Answer:

The region with the highest population density is Binky Lee

The region with the lowest population density is Cheslen

Step-by-step explanation:

we know that

The population density is the number of people per unit of area

Find out the population density for each region

Bear Creek

$\frac{462}{112}= 3.70\ people/acre$

Binky Lee

$\frac{12,624}{3,412}= 4.13\ people/acre$

Cheslen

$\frac{3,537}{1,263}= 2.80\ people/acre$

Crow's Nest

$\frac{2,142}{612}= 3.5\ people/acre$

Cheslen < Crow's Nest < Bear Creek < Binky Lee

therefore

The region with the highest population density is Binky Lee

The region with the lowest population density is Cheslen
