150x^5-60x^4-119x^3+5x-6/5x-1
Answer:
If a normal distribution is considered, a standard deviation (SD) is accounted for 34% (0.34 of population).
60 participants <=> p = 0.25
SD <=> p = 0.34
=> SD = 60 x 0.34/0.25 = 81.6 = ~82 participants.
Hope this helps!

Answer:
The number of movies must be greater than 10
Step-by-step explanation:
Let
x ----> the number of movies
y ----> the total cost
we know that
The linear equation in slope intercept form is equal to

where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
<em>Membership</em>
The slope is equal to

The y-intercept is equal to
---> enrollment fee
so
The linear equation is
----> equation A
<em>Non-Members</em>
The slope is equal to

The y-intercept is equal to
---> Is a proportional relationship
so
The linear equation is
----> equation B
Solve the inequality



Divide both sides by -3
Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so

therefore
The number of movies must be greater than 10
