f(x) = x!!! + x!! - x!
f(5) = ...​

Answer 1

Verified answer

3,4,5,6,7,8,9

Mean dari data diatas

3+4+5+6+7+8+9/7

7+11+15+9/7

42/7

6

Kesimpulannya

• rata rata dari data di atas adalah 6

f(x) = x!!! + x!! - x!

f(5) = 5!!! + 5!! - 5!

f(5) = 5 x 2 + 5 x 3 x 1 - 5 x 4 x 3 x 2 x 1

f(5) = 10 + 15 - 20 x 6

F(5) = 10 + 15 - 120

f(5) = 25 - 120

f(5) = -95

Nomor 1

Nilai rata-rata:

[tex] \bar{x} = \frac{3 + 4 + 5 + 6 + 7 + 8 + 9}{7} [/tex]

[tex] \bar{x} = \frac{42}{7} [/tex]

[tex] \bar{x} = \bold6[/tex]

[tex] \\ [/tex]

Nomor 2

f(x) = x!!! + x!! - x!

f(5) = 5!!! + 5!! - 5!

f(5) = 5 × 2 + 5 × 3 - 5 × 4 × 3 × 2 × 1

f(5) = 10 + 15 - 20 × 6 × 1

f(5) = 10 + 15 - 120 × 1

f(5) = 10 + 15 - 120

f(5) = 25 - 120

f(5) = -95
