The answer to the given permutation and combination are

  • 30240
  • 15
  • 58500
  • 9
  • 252

To solve the given problems, we have to use permutation and combination

<h3>Permutation and Combination</h3>

This is a topic in mathematics that deals with the probability or number of ways an event can occur.

a)10P5

_1_0P_5 = 30240

b) 6C2

_6C_2 = 15

c) This will be a multiplication of permutation of number. This becomes

_2_6P_2 * _1_0P_2 = 58500

This can happen in 58,500 ways.

d) To arrange 9 blocks in a row, she can do it in

_9C_1 = 9

she can do this in 9 ways

e) This can be solved using combination by writing it as

_1_0C_5 = 252

She can do this in 252 ways.

From the above calculations, the answer to the given permutation and combination are

  • 30240
  • 15
  • 58500
  • 9
  • 252

Calculate the value of the sample variance. Round your answer to one decimal place. 9_5,9_5,2,9_5
Ugo [173]

Answer:

s^2 = 0.01

Step-by-step explanation:

Given

Values: 9/5, 9/5, 2, 9/5

Required

Calculate the sample variance

Sample variance is calculated using:

s^2 = \frac{\sum (x_i - \overline x)^2}{n - 1}

First, we calculate the mean

\overline x = \frac{\sum x}{n}

\overline x = \frac{9/5 + 9/5 + 2 + 9/5}{4}

\overline x = \frac{7.4}{4}

\overline x = 1.85

s^2 = \frac{\sum (x_i - \overline x)^2}{n - 1} becomes

s^2 = \frac{(9/5 - 1.85)^2+(9/5 - 1.85)^2+(2 - 1.85)^2+(9/5 - 1.85)^2}{4 - 1}

s^2 = \frac{(-0.05)^2+(-0.05)^2+(0.15)^2+(-0.05)^2}{4 - 1}

s^2 = \frac{0.0025+0.0025+0.0225+0.0025}{3}

s^2 = \frac{0.03}{3}

s^2 = 0.01

<em>Hence, the variance is 0.01</em>
