Keith_Richards [23]

Answer: She lined up the front numbers instead of the decimal places.

Step-by-step explanation:

A correct addition or subtraction in decimals should be lining up decimal places in order to make sure that you are adding or subtracting in the same place.

1.56 + 13.47=15.03

F(x)= -2x + 2; Find f(5)
zhuklara [117]
If f(x) = -2x + 2, f(5) can be found by substituting in the value 5 for x in the equation:

f(5) = - 2(5) + 2

Our first step in simplifying this expression is to perform the multiplication as outlined by the order of operations (PEMDAS).

f(5) = -10 + 2

Finally, we must get our final answer by adding together the remaining terms.

f(5) = -8

Hope this helps!

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
