If, instead of the second electron coming in from infinity, it is initially at x = + 20.00 m on the axis and is given an initial
Brut [27]

Answer:

If the electron keeps that speed, then yes.

Step-by-step explanation:

The electron is given an initial position in the space, and is given a positive velocity and a direction towards the origin. Since the distance is finite, eventually, by keeping the same velocity and direction it will reach the origin At some time.

If the speed gradually decreases, it may be the case that the particle will never reach the origin (even though it may never stop), but since the problem doesnt state anything i am assuming that is not the case.

The width of a rectangle is 5 n minus 1.5 feet and the length is 1.5 n plus 9 feet. Find the perimeter of the rectangle.
andre [41]

Answer:

Perimeter= 13n+15

Step-by-step explanation:

We know that

Length(l) = 1.5n + 9 ft

Width(w) = 5n - 1.5 ft

The formula for the perimeter(P) of a rectangle is:

P=2l+2b \\or \\P=2(l+b)

So by substituting l and w we get :

P= 2[(1.5n+9)+(5n-1.5)]

P= 2[(1.5n+9)+(5n-1.5)]

P= 2[1.5n+5n+9-1.5]

P= 2[6.5n+7.5]

P= 13n+15

Your company is considering submitting a bid on a major project. You determine that the expected completion time is 130 weeks an
Olenka [21]

Answer:

Option C) 146.5

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 130 weeks

Standard Deviation, σ = 10 weeks

We are given that the distribution of completion time is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

P(X<x) = 0.95

We have to find the value of x such that the probability is 0.95

P(X < x)  

P( X < x) = P( z < \displaystyle\frac{x - 130}{10})=0.95  

Calculation the value from standard normal z table, we have,  

P(z

\displaystyle\frac{x - 130}{10} = 1.645\\x = 146.45 \approx 146.5  

The project should be completed in 146.5 weeks or less.

Hence, 146.5 weeks should be set the due date such that there is a 95 percent chance that the project will be finished by this time.
