In order to prove that more tv time causes bad grades we would need to do a controlled Experiment.
The correlation between time spent watching television and grades in school suggests a relationship between the two variables, but it does not necessarily prove causality. In order to establish a causal relationship between the two variables, it is necessary to conduct a controlled experiment.
In a controlled experiment, the independent variable (in this case, TV time) is manipulated, while the dependent variable (grades in school) is measured. By controlling for other possible factors that may affect grades, such as study habits, home environment, and socio-economic status, it is possible to determine whether changes in TV time directly impact grades in school. This would provide stronger evidence for a causal relationship between the two variables.

Step-by-step explanation:
Tafu is working with subatomic particles in the Physics lab. A positron is traveling in a straight line down the particle accelerator. Tafu models its position with the function p(t)=t^2/t−1 where t >1.
Calculate
a)limt→[infinity]p(t)
b)limt→1+p(t)
c)limt→2p(t)
The limit value for each function is:
a)limt→[infinity]p(t) = ∞b)limt→1+p(t)= 1.c)limt→2p(t)=0a) To calculate limt→[infinity]p(t), we can start by dividing the numerator and denominator of the equation by t, to get:
p(t) = t/t-1
Next, we can take the limit of this expression as t approaches infinity:
limt→[infinity]p(t) = limt→[infinity]t/t-1
Since t is the only variable in the expression, as t approaches infinity, the expression will approach infinity as well. Therefore, limt→[infinity]p(t) = ∞
b) To calculate limt→1+p(t), we can start by rewriting the equation as p(t) = 1/(t-1). Next, we can take the limit of this expression as t approaches 1:
limt→1+p(t) = limt→1 1/(t-1)
Now, we can use the limit laws to simplify the expression:
limt→1+p(t) = 1/limt→1(t-1)
Since the denominator is approaching 0 as t approaches 1, the expression approaches infinity. Therefore, limt→1+p(t) = 1.
c) To calculate limt→2p(t), we can start by dividing the numerator and denominator of the equation by t2, to get:
p(t) = 1/t-1
Next, we can take the limit of this expression as t approaches 2:
limt→2p(t) = limt→2 1/t-1
Now, we can use the limit laws to simplify the expression:
limt→2p(t) = 1/limt→2(t-1)
Since the denominator is approaching 0 as t approaches 2, the expression approaches infinity. Therefore, limt→2p(t) = 0.

for the following exercises, determine whether the vector field is conservative and, if it is, find the potential function. 107. f(x, y)
To determine whether the vector field f(x,y) = (6x + 5y)i + (x - 2y)j is conservative, we must first calculate its curl. The curl of the vector field is the vector field given by the equation:
curl(f(x,y)) = (5 - 2)i + (1 + 6)j = 3i + 7j
Since the curl of the vector field is equal to zero, this means that the vector field is conservative.
To find the potential function for this vector field, we need to calculate the line integral of the vector field along any closed path. In other words, we need to calculate the following integral:
V(x,y) = ∫C f(x,y) ⋅ ds
Where C is any closed path. We can solve this integral using the fundamental theorem of calculus, which states that the line integral of a conservative vector field is equal to the difference between the potential function evaluated at the two end points of the path.
Thus, we can solve for the potential function by finding the value of the potential function at two points and taking the difference of these values. For example, we can choose the points (0,0) and (1,1). At (0,0), the potential function is 0, and at (1,1), the potential function is 3 + 5 + (-2) + 1 = 7. Thus, the potential function is V(x,y) = 3x^2 + xy + 2y^2.

Supposed that the membrane starts to vibrate from rest. Determine the position of each point on the membrane for t>0. For this problem take c= t so that the equation to solve is up 3 (14+Uv) ; 0
The position of each point on the membrane for t>0 is given by u(x,y,t) = x(x-1)y(y-1) + (14+u) c2t.
The position of each point on the membrane can be determined by solving the equation u xx + u yy = c2u, where u is the displacement of the membrane from its equilibrium position and c is the speed of the wave propagation. Since we are given f(x,y) = x(x-1)y(y-1), we can solve this equation to find u. Differentiating f(x,y) twice with respect to x and y gives us the corresponding derivatives of u. Plugging these derivatives into the equation gives us u xx + u yy = (14+u) c2. Solving this equation yields the displacement of each point on the membrane for t>0. Thus, the position of each point on the membrane for t>0 is given by u(x,y,t) = x(x-1)y(y-1) + (14+u) c2t.

The definite integral is the difference between the values of the antiderivative evaluated at the limits of integration, and the value of the definite integral can only be found if the limits of integration are known. Therefore, the answer is neither A nor B.

Which best represents the equation of the line below?
2x y = 2
The solution is Option C.
The equation of line is y = 2x - 2 , where the slope m = 2
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
2x - y = 2 be equation (1)
On simplifying the equation , we get
Adding y on both sides of the equation , we get
y + 2 = 2x
Subtracting 2 on both sides of the equation , we get
y = 2x - 2
Therefore , the value of A is y = 2x - 2
Hence , the equation of line is y = 2x - 2 and the graph is plotted

When making or analysing a histogram, you should keep in mind the following words and concepts.
Skewness of a normal distribution
kurtosis
Your histogram will be symmetrical if the data on which it is based are regularly distributed.
Your histogram will be positively biassed if it has more little than large numbers. Your histogram will be negatively skewed if there are more large than little numbers.
positive skew... mean... median... mode... mode Mean Median Mode = median = mean with a negative skew
