Answer:
What is the degrees of freedom when the sample size is 20?
19
For example, if we have a sample of size n = 20 items, then we calculate the degrees of freedom as df = n – 1 = 20 – 1 = 19 and we write the distribution as T ~ t19.
Explanation:
The degrees of freedom can be used to test a hypothesis about the mean.
What is degrees of freedom?Degrees of freedom refers to the maximum number of logically independent values that have the freedom to vary, in the data sample.
Given, the sample size is 20, then degree of freedom will be
The degrees of freedom represented as
dof = n – 1
dof = 20 – 1
dof = 19
Thus, the degrees of freedom can be used to test a hypothesis about the mean.

The recommended percent p (in decimal form) of nitrogen (by volume) in the air that a diver breathes is given by p=105.07d+33, where d is the depth (in feet) of the diver. find the depth when the air contains 47% recommended nitrogen by (a) solving an equation, and (b) using the inverse of the function. round to the nearest tenth.
The depth of the diver when the air contains 47% recommended nitrogen is -0.3 ft
To answer the question, we need to know what an equation is.
What is an equation?An equation is a mathematical function that shows the relationship between two variables.
Given that he recommended percent p (in decimal form) of nitrogen (by volume) in the air that a diver breathes is given by p = 105.07d + 33, where d is the depth (in feet) of the diver.
Solving for the depth by solving the equationTo find the depth when the air contains 47% recommended nitrogen, we solve the equation with p = 47%
So, p = 105.07d + 33
47% = 105.07d + 33
0.47 = 105.07d + 33
0.47 - 33 = 105.07d
-32.53 = 105.07d
d = -32.53/105.07
d = -0.3096 ft
d ≅ -0.3 ft
Solving for the depth using the inverse functionSince p = 105.07d + 33
Making d subject of the formula, we have
d = (p - 33)/105.07
Substituting p = 47% = 0.47, we have
d = (0.47 - 33)/105.07
d = -32.53/105.07
d = -0.3096 ft
d ≅ -0.3 ft
So, the depth of the diver when the air contains 47% recommended nitrogen is -0.3 ft

Two football players with mass 80 kg and 120 kg run directly toward each other with speeds of 8 m/s and 10 m/s respectively. if they grab each other as they collide, the combined speed of the two players just after the collision would be
The combined speed after the collision is -2.8 m/s.
How to get the combined speed?
Here we must have conservation of momentum, where momentum is the product between mass and velocity.
At the beginning, one of the players has a mass of 80kg and a velocity of 8m/s, so its momentum is:
P₁ = 80kg*(8m/s) = 640 kg*m/s
The other player has a mass of 120 kg and runs in the opposite direction at a speed of -10m/s (the negative sign is because of the direction). So its momentum is:
P₂ = 120kg*(-10m/s) = -1200 kg*m/s
The initial total momentum is:
P = P₁ + P₂ = 640 kg*m/s + ( -1200 kg*m/s) = -560 kg*m/s
At the end, the move together as a mass of (80kg + 120kg) = 200kg with a velocity V.
Such that the final total momentum is equal to the initial total momentum.
So we must have:
200kg*V = -560 kg*m/s
V = (-560 kg*m/s)/200kg = -2.8 m/s.
The combined speed after the collision is -2.8 m/s.

If r is a commutative ring, show that the characteristic of r[x] is the same as the characteristic of r.
If R is a commutative ring, then, the characteristic of R{x} is the same as the characteristic of R.
What is a commutative ring?In ring theory, a commutative ring can be defined as a ring in which the multiplication operation is considered to be commutative in nature.
Let R represent a commutative ring with characteristic K.
Therefore, we have: Kr = 0∀r ∈ R.
Assuming f(x) ∈ R(x)
Then, f(x) would be given by: [tex]a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0=0[/tex]
Also, in some instances ai ∈ R and n ∈ N.
Finally, we would have:
[tex]Kf(x) = K(a_n x^n + a_{n-1} x^{n-1} +.......+ a_1 x^1 +a_0)\\\\Kf(x) = Ka_n x^n + Ka_{n-1} x^{n-1} +.......+ Ka_1 x^1 +Ka_0\\\\Kf(x) = 0\times x^n + 0\times x +.......+ 0[/tex]
Kf(x) = 0.
