Answer:
Median.
Step-by-step explanation:
The median is a better measure than the mean when there is an outlier.
The numbers Three and Twelve give you a product of 36, and a sum of 15
Y=-x+2
OR if you are looking for point slope:
y+1=-1(x-3)
Answer:
8
Step-by-step explanation:
goes plus 1 then plus 2 then plus 3 so then it would be plus 4
Answer:
At 43.2°.
Step-by-step explanation:
To find the angle we need to use the following equation:

Where:
d: is the separation of the grating
m: is the order of the maximum
λ: is the wavelength
θ: is the angle
At the first-order maximum (m=1) at 20.0 degrees we have:

Now, to produce a second-order maximum (m=2) the angle must be:


Therefore, the diffraction grating will produce a second-order maximum for the light at 43.2°.
