Simplify.
Alika [10]

Solution:

<u>Note that:</u>

  • Given expression: (x² + 4x) − (x² + 6x − 3)

<u>Remove the brackets</u>

  • (x² + 4x) − (x² + 6x − 3)
  • => x² + 4x - x² - 6x + 3

<u>Combine like terms</u>

  • x²(1 - 1) + x(4 - 6) + 3
  • => x²(0) + x(-2) + 3
  • => -2x + 3

Lyme disease is an inflammatory disease that results in a skin rash and flulike symptoms. It is transmitted through the bite of
neonofarm [45]

Answer:

Step-by-step explanation:

Let cases of Lyme disease = x

x = 2, 1, 3, 4, 5, 1, 2, 1, 6, 5, 4, 1

\sum x = 35

\sum x^2 = 139

y = 0, 1, 2, 1, 3, 5, 2, 3, 3, 3, 1, 0

\sum y = 24

\sum y^2 = 72

\sum xy = 55

S_{xx} = \sum x^2 - (\sum x)^2/n\\S_{xx} = 139 - 35^2/12\\S_{xx} = 36.92\\S_{yy} = \sum y^2 - (\sum y)^2/n\\S_{yy} = 72 - 24^2/12\\S_{yy} = 24

S_{xy} = \sum xy - ( \sum x \sum y)/n\\S_{xy} = 55 - (35*24)/12\\S_{xy} = -15

b) Linear correlation between Lyme disease and drowning deaths.

r = \frac{S_{xy}}{\sqrt{S_{xx}S_{yy}} }

r = -15/ √(24*36.92)

r = -0.504
