The weights of a sample of college textbooks has a bell-shaped distribution with a mean of 8.1 p o u n d s ( l b s ) and a stand

weeeeeb [17]

Answer:

The interval ( 1,8 ; 14,4 ) will contains 99,7 % of all values

Step-by-step explanation:

For Normal Distribution N ( μ ; σ ) the Empirical Rule establishes that in the intervals:

( μ ± σ ) we find 68,3 % of all values

( μ ± 2σ ) we find 95,4 % of all values

( μ ± 3σ ) we find 99,7 % of all values

Then we have a normal distribution N ( 8,1 ; 2,1 )

3*σ = 3* 2,1 = 6,3

And 8,1 - 6,3 = 1,8 8,1 + 6,3 = 14,4

Then the interval ( 1,8 ; 14,4 ) will contains 99,7 % of all values

Factor the polynomial completely 12x^4-42x^3-90x^2

Alborosie

Factor the following:
12 x^4 - 42 x^3 - 90 x^2

Factor 6 x^2 out of 12 x^4 - 42 x^3 - 90 x^2:
6 x^2 (2 x^2 - 7 x - 15)

Factor the quadratic 2 x^2 - 7 x - 15. The coefficient of x^2 is 2 and the constant term is -15. The product of 2 and -15 is -30. The factors of -30 which sum to -7 are 3 and -10. So 2 x^2 - 7 x - 15 = 2 x^2 - 10 x + 3 x - 15 = x (2 x + 3) - 5 (2 x + 3):
6 x^2 x (2 x + 3) - 5 (2 x + 3)

Factor 2 x + 3 from x (2 x + 3) - 5 (2 x + 3):
Answer: 6 x^2 (2 x + 3) (x - 5)
