Using the permutation formula, as the order is important, it is found that 2520 distinct passwords can be made.
The order is important as abcde is a different password than edcba, hence the permutation formula is used.
What is the permutation formula?The number of possible permutations of x elements from a set of n elements is given by:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this problem, 5 letters are chosen from a set of 7, hence:
[tex]P_{7,5} = \frac{7!}{(7-5)!} = 2520[/tex]
2520 distinct passwords can be made.

There are 150 people ina golf club.a) there are 50%more men than women in the golf club. How many mena nd how many women are ther in the golf club.
The percentage computed shows that the number of women is 60 while men are 90.
How to calculate percentage?Let the number of women be represented by x.
Since there are are 50% more men than women in the golf club, the number of men will be:
= x + (50% × c)
= x + 0.5x
= 1.5x
Therefore, 1.5x + x = 150
2.5x = 150
x = 150/2.5
x = 60
Number of women = 60
Number of men = 1.5x = 1.5 × 60 = 90

let n (AUB)=32n(B)=16and n(ANB)9 find n (A)
Answer:
32
Step-by-step explanation:
n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)
Given n(A)= ? we represent with x
n(B)= 16
n(A∪B) = 32
Substituting in equation 1 to get n(A)
32 = n(A) + 9 − 9
⇒n(A) = 32 − 0
n(A) = 32
to confirm this we put the values into the formula below
n(A∪B)=n(A)+n(B)−n(A∩B)−−−−−−−(1)
32 = 32 + 9 - 9
Answer:
n(A) = 25
Step-by-step explanation:
The relation between cardinality of two sets and that of their union and intersection is ...
n(A∪B) = n(A) +n(B) -n(A∩B)
32 = n(A) +16 -9 . . . . . use the given information
25 = n(A) . . . . . . . . . subtract 7

We can write the two given inequalities as:
0 < x < 1/3
And the graph of it can be seen below.
How to graph the inequalities?
Here we want to graph the inequalities:
x < 1/3
x > 0.
To do it, we can rewrite the inequality as:
0 < x < 1/3.
To graph this, we need to work with a number line. First, we will mark both of the ends of the inequality, that is x = 0 and x = 1/3, both will be graphed with open circles, which means that these points are not solutions. Then, we need to shade the region between these points.
The graph can be seen below.

Step-by-step explanation:
The required expression, six times the quotient of thirty-two and
eight, increased by seven, is given as x = 6(32/8) + 7.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the expression equal to x,
According to the question,
Six times the quotient of thirty-two = 6(32 /8)
Increased by seven = 6(32 /8) + 7
X = 6(32 /8) + 7
Thus, the required expression, six times the quotient of thirty-two and

Answer:
application of L'Hopital's rule to the presumed indeterminate form yields this conclusion
Step-by-step explanation:
This is a reverse application of L'Hopital's rule for determining the limits involving indeterminate forms.
When the expression evaluated at the limit is 0/0, then L'Hopital's rule tells you the limit can be found from n'/d', where n and d are the numerator and denominator of the original expression, respectively.
We can see that x-π = 0 at x=π, so we assume that f(π) = 0 as well, and the expression n/d = f(x)/(x-π) evaluates to the indeterminate form 0/0.
The derivatives are ...
n' = f'(x)
d' = 1
Then we have the limit as ...
lim{x→π) = n'/d' = f'(π)/1 = 3 ⇒ f'(π) = 3
The conclusion f(π)=0 and f'(π)=3 follows from L'Hopital's Rule.
