A bored statistics student wants to determine if there is a relationship between the number of cigarettes smoked (X) and the number of beers drunk (Y) over the duration of a televised Buffalo Bills game. Below is the data:
X Y
2 3
3 1
6 5
4 4
5 2
Mx = 4 My = 3
In determining if there is a relationship between cigarette smoking and beer consumption, what is the obtained Pearson's product moment correlation coefficient (r)?
a. r = 0.05
b. r = 0.25
c. r = 0.50
d. r = 0.07

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

y/x=18

step-by-step explanation:

2nd one in the first row is correct
