Step-by-step explanation:
- Permutation is an example of the mathematics in which item are arranged in different way.
- For example ABC, ACB, BCA, CBA, CAB, BAC etc.
- The order of an arrangement are different in each alphabet.
- The product of number also be defined as in the form of n to 1
- for example : 5*4*3*2*1 = 120

Given that Kimora’s cell phone company charges her $35 a month for phone service plus $.05 for each text message sent.
Kimora's cell phone bill for one month is $52.
We need to determine the number of text messages Kimora sent for one month.
Also, we need to write and equation and solve it.
<u>The equation:</u>
Let x denote the number of text messages Kimora sent for one month.
Thus, the equation is given by
Therefore, the equation for the number of text messages Kimora sent for one month is
<u>Solving the equation:</u>
We need to solve the equation
Subtracting both sides of the equation by 35, we get;
Dividing both sides of the equation by 0.05, we get;
Therefore, the number of messages sent is 340.

Step-by-step explanation:
dimeter is twice the radius or radius is half of diameter
Answer:
a) 2/3
b) 1/3
Step-by-step explanation:
Let X be the random event that measures the time you will have to wait.
Since time is uniformly distributed between 10 and 10:30 in intervals of 1 minute
P(n < X ≤ n+1) = 1/30 for every minute n=0,1,...29.
a)
P( X > 10) = 1 - P(X ≤ 10) = 1 - 10/30 = 2/3
b)
P(10 < X ≤ 20) = (20-10)/30 = 1/3
We can adjust the data by adding 4 to everything before we calculate the statistics. Or we can calculate the statistics on the given data and just add 4 to everything at the end. We'll get the same answer either way.
Let's sort the seven data points: 5 5 5 7 7 9 10
Those add up to 48 so the mean is 48/7 = 6.9
The one in the middle is 7 so the median = 7
The mode is the most common one, mode = 5
The range is the difference between max and min, so range = 10 - 5 = 5
In the second week we add four to everything. Since that adds four to the min and max, the range doesn't change.
Answer: mean=10.9, median=11, mode=9, range=5
