Answer:
we can see that the x or the first number in both are 2 so there is no distance there, where there is a distance is the y which to find out we can just do 2.5-1.2=1.3
the distance between the two points is 1.3
Its 5 because you have to change 28 into a fraction by putting a one under like so 28/1
Answer:
x(aka the number) = -16
This is because 4 times -16 = -64, and -64 plus 57 = -7.
Step-by-step explanation:
Answer:
0.099, 0.969,0.87,8.3.1.063
Step-by-step explanation:
Let X be the left handed people in the sample of 10 people selected.
X is binomial with n=10 and p = 0.13
a) the probability that there are exactly 3 lefties in the group
=
b) the probability that there are at least 3 lefties in the group
=
Now Y number of right handers is binomial with n =10 and p = 0.87
c) the expected number of right-handers in the group.

d) the standard deviation of the number of right-handers in the group
=
