Answer:
b. day 2 is the farthest from 0
Answer:
192
Step-by-step explanation:
There are a total of 15 marbles . When the lavender is left out 14 remain.
Using combinations we find that each of the four color marbles can be chosen in the following way.
2C1*4C1*4C1*6C1= 2*4*4*6= 192
We select one of the two red marbles , one of the four green marbles, one of the four yellow marbles, one of the 6 orange marbles leaving the lavender out.. We apply combinations and then multiply to get the answer.
Answer with explanation:
Given : The heights of a certain population of corn plants follow a normal distribution with mean
and standard deviation 
a) Using formula
, the z-value corresponds to x= 135 will be

At x= 155, 
The probability that plants are between 135 and 155 cm tall :-

Hence, 34.73% of the plants are between 135 and 155 cm tall.
b) Sample size : n= 16
Using formula
, the z-value corresponds to x= 135 will be

At x= 155, 
The probability that plants are between 135 and 155 cm tall :-

Hence,The percentage of the samples would the sample mean height be between 135 and 155 cm.= 93.12%
The thickness of the non-reflective coating layer is 9.62 x 10¯⁸ m or 96.2 nm.
From the question we know that :
n = 1.30
λ = 500nm = 5 x 10¯⁷m
The non-reflective coating system is applied on glass and the refractive index of that system should be <em>nair</em> < <em>ncoating</em> < <em>nglass. </em>The light travels across the air and is refracted by coating film and then refracted again by the glass. For preventing the light got reflected by glass, the thickness of the layer should obey this equation :
2nt = λ/2
t is the thickness of the layer, λ is the wavelength and n is the refractive index of the film.
By substituting the following equation we get
2nt = λ/2
t = 1/4 . ( λ / n )
t = 1/4 . ( 5 x 10¯⁷ / 1.3)
t = 9.62 x 10¯⁸ m
Hence, the thickness of the non-reflective coating layer is 9.62 x 10¯⁸ m or 96.2 nm.

The answer would be 15 because the problem states that it takes 8 hours to build 5 birdhouses and they want to know how many she can build in 24 hours if you multiply 8 and 5 with the number 3 you would get 24 hours and 15 birdhouses.
