Answer:
p = 70n -1500
Step-by-step explanation:
The slope-intercept form of the equation is ...
p = 70n +b
We know that p = -800 for n = 10, so we can find b:
-800 = 70·10 +b
-800 -700 = b = -1500
The net profit equation is ...
p = 70n -1500
Answer:
a) P(X = 0) = 0.5997
b) P(X = 9) = 0.0016
c) P(X = 8) = 0.0047
d) P(X = 5) = 0.4018
Step-by-step explanation:
These following problem are examples of the binomial probability distribution.
Binomial probability
Th binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinatios of x objects from a set of n elements, given by the following formula.

And
is the probability of X happening.
(a) for n = 4 and π = 0.12, what is P(X = 0)?

(b) for n = 10 and π = 0.40, what is P(X = 9)?

(c) for n = 10 and π = 0.50, what is P(X = 8)?

(d) for n = 6 and π = 0.83, what is P(X = 5)?

Answer:
x=-85
Step-by-step explanation:
x-18=-103
x=-103+18
x=-85
Hi! For this question all you have to do is subtract 43 from 72.
72 - 43 = 29
Trina had 29 stamps left.
Hope this helps! Happy Thanksgiving!
N would equal 28 since 60-32 is 28
