Mathematics
2 answers:
vekshin13 years ago
6 0

Answer:

C(n,n)=1

Step-by-step explanation:

C(n,n) means we have to find the combination when n objects are to be selected from n objects.

Formula for C(n,r) is

\dfrac{factorial\ n}{factorial\ r\times factorial\ (n-r)}

Here, r=n

C(n,n) is equal to

\dfrac{factorial\ n}{factorial\ n\times factorial\ (n-n)}

\dfrac{factorial\ n}{factorial\ n\times factorial\ (0)}

since, factorial 0=1

Hence, C(n,n)=1

The weekly salaries of a sample of employees at the local bank are given in the table below. Employee Weekly Salary Anja $245 Ra
evablogger [386]

The variance for the data is  17,507. 5.

Given

The weekly salaries of a sample of employees at the local bank are given in the table below.

Employee Weekly Salary Anja $245 Raz $300 Natalie $325 Mic $465 Paul $100.

<h3>Variance</h3>

Variance is the expected value of the squared variation of a random variable from its mean value, in probability and statistics.

The mean value of the salaries of employees is;

\rm Mean= \dfrac{245+300+325+465+100}{5}\\\\Mean=287

The variance is given by;

\rm  Variance=\sqrt{\dfrac{(245-287)^2 +(300-287)^2 +(325-287)^2 +(465-287)^2 +(100-287)^2}{5-2}} \\\\Variance = 132.316}\\\\On \ Squaring \ both \ the \ sides\\\\Variance^2=17,507. 5

Hence, the variance for the data is  17,507. 5.

(q^4)^z= q^12 find the value of z
juin [17]

Answer:

z = 3

Step-by-step explanation:

we use the method

(x^a)^b = x^(a*b)

so

(q^4)^z = q^(4*z)

now

4*z = 12

z = 12 / 4

so

z = 3
