Answer:
Despite some evidence that suggest that finger ring use is associated with higher bacterial
colonization, healthcare providers continue to wear finger rings in a healthcare setting. The aim
of this systematic review was to synthesize the evidence to date regarding whether finger ring
use increases bacterial colonization of healthcare providers' hands. Articles that studied the
association finger ring use with hand hygiene and bacterial colonization were searched using
PubMed, Google Scholar, and Georgia State University's online library systems. The overall
results of this review suggest that finger ring use does increase the bacterial colonization on the
hands of HCPs but not with significant difference when compared to no finger ring use;
therefore, further research needs to be conducted to decide whether finger rings should be used in
a healthcare setting or not.
Variance is the standard deviation squared but we're not going to use that now. Let's first calculate the mean:
mean = (17+13+13+22+11+20)/6 = 16.
Now for each value, let's see how far it is from this mean. We'll square these distances and average them. That's our variance.
17 distance 1 squared = 1
13 distance 3 squared = 9
13 distance 3 squared = 9
22 distance 6 squared = 36
11 distance 5 squared = 25
20 distance 4 squared = 16
Now average these outcomes:
variance = (1+9+9+36+25+16)/6 = 16.
So the variance by coincidence is the same as the mean.
Answer C is your answer.
13*13= 169
12*19= 228
19*62= 1,178
This was very easy.
Let
A (1,6)------> location brianna's house on a map
B (5,3)------> location Jordan's house on a map
we know that
One possible path from brianna's house to jordan's house it's a straight line ( the shortest distance)
using a graph tool
see the attached figure
find the distance points AB
d=√[(y2-y1)²+(x2-x1)²]-----> d=√[(3-6)²+(5-1)²]----> d=√[3²+4²]d=√25----> d=25 units
the distance from brianna's house to jordan's house is 25 units

are u sure thet write the question right?
