Find the ordered triple to represent u in u=6w+2z if v=(4,-3,5) w=(2,6,-1) and z=(3,0,4)

Mathematics

Answer:

u = (18, 36, 2)

Step-by-step explanation:

Given:

  • v=(4,-3,5)
  • w=(2,6,-1)
  • z=(3,0,4)

and u = 6w+2z  

Putting the values of v,w and z in u, we have:

u = 6(2,6,-1)+ 2(3,0,4)

<=> u = (12, 36, -6) + (6, 0, 8)

<=> u = (12+6, 36+0, -6+8)

<=> u = (18, 36, 2)

Suppose 1% of cotton fabric rolls and 4% of nylon fabric rolls contain flaws. Of the rolls used by a manufacturer, 70% are cotto
Amanda [17]

Answer:

0.019 or 1.9%

Step-by-step explanation:

The probability that a randomly selected roll used by the manufacturer contains flaws is determined by the probability of a flawed cotton roll occurring (1% x 70%) added to the probability of a flawed nylon roll occurring  (4% x 30%) .

P(F) = P(C)*P(F_C)+P(N)*P(F_N)\\P(F) = 0.7*0.01+0.3*0.04\\P(F) = 0.019 = 1.9\%

The probability that a randomly selected roll contains flaws is 0.019 or 1.9%

Solve for y 2x+y-3z=5
Elza [17]

Answer:

<h3>A. y=-2x+3z+25</h3>

Step-by-step explanation:

Isolate the term of x and y from one side of the equation.

<u>To solve:</u>

  • The value of y.

\Longrightarrow: \sf{\sqrt{2x+y-3z}=5}

<h3>2x+y-3z=25</h3>

<u>First, you have to subtract by 2x-3z from both sides.</u>

\Longrightarrow: \sf{2x+y-3z-\left(2x-3z\right)=25-\left(2x-3z\right)}}

<u>Solve.</u>

\Longrightarrow: \boxed{\sf{y=25-2x+3z}}}

  • <u>Therefore, the correct answer is "A. y=-2x+3z+25".</u>

I hope this helps, let me know if you have any questions.
