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

A surveyor measures the length of a surveying chain containing 1000 chain links. The length is 0.061km. What is the length of a
AleksandrR [38]

The length of a single chain link in centimeters is 61cm

<h3>Fractions and ratios</h3>

Fractions are written as a ratio of two integers. Given the following information;

Total chain length = 1000chain

If the length of the chain is 0.061km, the length of each single chain link is expressed as:

Single chain = length of chain/1000

Single chain = 0.061km/1000

Single chain = 0.000061km

Convert to cm

0.000061km = 0.000061 * 10^6 cm

0.000061km = 61cm

Hence the length of a single chain link in centimeters is 61cm

Melissa poured 1/4 can of syrup into a bowl. She spilled 1/5 of the syrup into a bowl that was left of the can. What fraction of
Leto [7]
To make this easier we can convert the fractions to whole numbers and then back. 
Lets have 100 represent the can. 
1/4 = .25 so we will convert it to 25
100 - 25 = 75
1/5 of 75 is 15
75 - 15 = 60
60/100 = 6/10 = 3/5
