Answer:
The binomial mean, or the expected number of successes in n trials, is E(X) = np. The standard deviation is Sqrt(npq), where q = 1-p. The standard deviation is a measure of spread and it increases with n and decreases as p approaches 0 or 1.
Step-by-step explanation:
Answer:
a=3
b=3
Step-by-step explanation:
(2xy)^4
----------------
4xy
Expand the numerator
2^4 x^4 y^4
---------------------
4xy
Simplify
16 x^4 y^4
---------------------
4xy
We know that a^b / a^c = a^(b-c)
16/4 * x^(4-1) y^(4-1)
4 x^3 y^3

Since you cannot have a fraction amount of a box, you will need to round up(you cannot NOT put in any books either, so you must round up).
118 rounded to the nearest multiple of is 120
120/5=
20+4=
24
24 boxes!

Answer:
A second point would be (-1, -6)
Step-by-step explanation:
Because the slope is -1, we know that for every number that x increases, we change y the amount of the slope. So, if we increase x by 1, we change y by -1.
x value
-2 + 1 = -1
y value
-5 - 1 = -6
