Write a polynomial function in standard form with given zero x=2,-1,-5
LekaFEV [45]

Answer:

Done below!

Step-by-step explanation:

(x - root)

(x - 2)(x - (-1))(x - (-5)) = (x - 2)(x + 1)(x + 5)

(x^{2} +x-2x-2)(x+5)=(x^{2} -x-2)(x+5)=x^{3}+5x^{2}-x^{2}   -5x-2x-10\\\\=x^{3}+4x^{2} -7x-10

The edge roughness of slit paper products increases as knife blades wear. Only 1% of products slit with new blades have rough ed
Masteriza [31]

Answer: Our required probability is 2.8%.

Step-by-step explanation:

Since we have given that

Probability of products slit with new blades have rough edges P(X) = 1%

Probability of products slit with blades of average sharpness exhibit roughness P(Y) = 3%

Probability of products slit with worn blades exhibit roughness P(Z) = 5%

Let A be the  selected product that exhibit edge roughness.

P(A|X) = 25% = 0.25

P(A|Y) = 60% = 0.60

P(A|Z) = 15% = 0.15

So, the probability of products that exhibit edge roughness is given by

P(X)P(A|X)+P(Y)P(A|Y)+P(Z)P(A|Z)\\\\=0.01\times 0.25+0.03\times 0.60+0.05\times 0.15\\\\=0.028\\\\=2.8\%

Hence, our required probability is 2.8%.
