Arisa [49]3 years ago

Answer & Step-by-step explanation:

For a polynomial of the form ax^{2}+bx+c , rewrite the middle term as a sum of two terms whose product is a×c=6×−12=−72        and whose sum is b=−1.

Factor −1 out of −x.

6x^{2}−(x)−12

Rewrite −1 as −9 plus 8

6x^{2}+(−9+8)x−12

Apply the distributive property.

6x^{2}−9x+8x−12

Factor out the greatest common factor from each group.

Group the first two terms and the last two terms.

(6x^{2}-9x)+8x−12

Factor out the greatest common factor (GCF) from each group.

3x ( 2 x − 3 ) + 4 ( 2 x − 3 )

Factor the polynomial by factoring out the greatest common factor,  2 x − 3 .

(2x−3)(3x+4)

There are 5 radar stations and the probability of a single radar station detecting an enemy plane is 0.55. What is the probabili
Lerok [7]
This is a binomial distribution with n = 5, p = 0.55, q = 1 - 0.55 = 0.45, x = 0, 1, 2, 3

P(x) = nCx p^x q^(n - x)
P(x ≤ 3) = 1 - P(x > 3) = 1 - [P(4) + P(5)]
P(4) = 5C4 x (0.55)^4 x (0.45) = 0.2059
P(5) = 5C5 x (0.55)^5 x 1 = 0.0503

P(x ≤ 3) = 1 - (0.2059 + 0.0503) = 1 - 0.2562 = 0.7438
