Answer:
The strong nuclear force holds together the quarks and gluons within protons and neutrons. It also holds together the protons and neutrons within the nucleus of the atom.
Step-by-step explanation:
7 * 0.5 + 3 * 0.8 = 3.5 + 2.4 = 5.9
<span>5.9/10 X 100 = 59%

Answer:
Step-by-step explanation:
In statistics, the standard deviation is a measure about the amount of variation of a dataset.
The variation is measured through comparison between each data and the mean of the dataset. This way, we could get a numerical information about how far are those values form the mean (which represents the central value).
The formula to find the standard deviation of a sample is
Where 
is the sample mean and 
is the total number of values there are.
In the formula you can notice the difference between each value (
) and the mean (), That's why the standard deviation is commonly use to measure variation.
Therefore, the answer is
Answer: 1/cos θ
Step-by-step explanation:
From basic trigonometry, csc θ is the short form of cosec θ which is further expressed as
csc θ = 1/sin θ
Also,
tan θ = sin θ/cos θ
Knowing this basis of trigonometry makes the simplification easy for us.
Firstly, expressing the equation in terms of sin θ and cos θ,
The equation becomes csc θ * tan θ = [1/sin θ] * [sin θ/ cos θ]
Further simplifying by multiplication, our answer becomes
1/cos θ
