ICE Princess25 [194]

Answer:

2.18

Step-by-step explanation:

The mean is the most familiar average. It is defined as a value obtained by dividing the sum of all observations by their number. It is calculated as

Mean = Sum of all the observations/ Number of the observations

Mean= x₁+x₂+...............+xₐ/n

Where x₁,x₂,...............,xₐ refer to different values of x and n is the sample size.

Mean= 2+1+2+2+2+2+1+3+3+3+3/11= 24/11= 2.18

The mean may correspond to a population or a sample from a population.

The population mean is a fixed quantity where as the sample mean is a variable quantity because different samples from the same population tend to have different means.

Write each sum using summation notation<br> 12 + 22 + 32 + 42 + ⋯ + 10000^2
Murljashka [212]

Answer:

50,00,70,000

Step-by-step explanation:

The given sequence is Arithmetic Progression.

Arithmetic Progression is a sequence in which every two neighbor digits have equal distances.

Here first we will find the number of terms

For finding the nth term, we use formula

aₙ = a + (n - 1) d

where, aₙ = value of nth term

a = First term

n = number of term

d = difference

Now, In given sequence: 12, 22, 32, 42, ⋯ , 100002

a = 12, d = 10, n = ? and  aₙ= 100002

∴ 100002  = 12 + (n - 1) × (10)

⇒ 99990 = 10(n - 1)

⇒ n = 10000

Now using the formula of Sum of Arithmetic Sequence,

Sₙ = n÷2[2a + (n - 1)d]

⇒ Sₙ = (10000÷2)[2 × 12 + 9999 × 10]

⇒ Sₙ = 5000 [ 24 + 99990]

⇒ Sₙ = 5000 × 100014 = 50,00,70,000
