margot measured the distance for 6 wavelengths of visible light as 2,400 nano meters what is the distance for 1 wavelength
mihalych1998 [28]

Answer:

400nanometers

Step-by-step explanation:

Based on Margot measurement, the distance for 6wavelengths of visible light is 2400nanometers. To calculate the resulting distance for 1wavelength we have:

6wavelength = 2400nanometers

1wavelength = x

6wavelength × x = 2400nanometers × 1wavelength

x = 2400nanometres/6

x = 400nanometres

Find the probability of at least three successes in six trials of a binomial experiment in which the probability of success is 5
Amanda [17]

Answer:

31.3%

Step-by-step explanation:

Start by doing the binomial expansion of (x+y)^6 where x represents success. This is  

(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6)  

We are interested in the x^3y^3 term which represents exactly 3 successes. Since the probability of success and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is  

20/64 = .3125 which is 31.25% Rounding yo the nearest tenth gives us
