Answer:
Find the distance between (-1, 1) and (3, 4).
This problem is solved simply by plugging our x- and y-values into the distance formula:
D=(3−(−1))2+(4−1)2−−−−−−−−−−−−−−−−−−√=
=16+9−−−−−√=25−−√=5
Sometimes you need to find the point that is exactly between two other points. This middle point is called the "midpoint". By definition, a midpoint of a line segment is the point on that line segment that divides the segment in two congruent segments.
If the end points of a line segment is (x1, y1) and (x2, y2) then the midpoint of the line segment has the coordinates:
(x1+x22,y1+y22)

Answer:
a) Check graph
b)Closer to 0.5
c)Researcher 1 is right.
Step-by-step explanation:
a) Please check attached graph.
b) Please check second graph. It is shown that the value is 0.387 which is closer to 0.5.
c) Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. The researcher 1 is right because there are numerous random variables are exist for this event and normal distribution function is the best function that gives less error for this numerous not-known random variables.

Answer:
warmer by 30.2 degrees
Step-by-step explanation:
It might help to think of these values plotted on a number line. Both temperatures will be left of zero, with -63°C being farther to the left (colder).
The difference can be found by subtracting the colder temperature from the warmer one:
-32.8 -(-63) = -32.8 +63 = 63 -32.8 = 30.2 . . . degrees
The South America temperature -32.8°C is 30.2° warmer than the North America temperature.
