What does the y-intercept represent in a linear regression equation?
It represents the value of the y variable when the x variable is zero.
What are the differences between negative growth rate and zero growth rate?
Negative means people are leaving. Zero means that people are coming and going in equal amounts.
What is earths eccentricity rounded to the nearest tenth?
The eccentricity of the Earth's orbit is currently about 0.0167; that rounds to zero.
What is the rate of change of 210 divided by 200?
1.05
WHAT IS EQUIVALENT RATE?
If you are given one rate, x/y then multiply (or divide) both numbers by any non-zero number. You will have an equivalent rate.
Could one explain what the zero rate is?
Zero rate has several meanings. The meaning differs on what zero rate is used for. For example, if it is used for loaning money, then "zero rate" might be used for zero interest rate.
What does it mean to say that a data point has a residual of zero?
The point lies directly on the regression line.
If you were in orbit how much force would you exert on a scale?
In orbit your weight is zero.
Why are your predictions inaccurate using a linear regression model?
There are many possible reasons. Here are some of the more common ones: The underlying relationship is not be linear. The regression has very poor predictive power (coefficient of regression close to zero). The errors are not independent, identical, normally distributed. Outliers distorting regression. Calculation error.
What does alpha mean in statistics?
In the context of regression, it is the y-intercept: the value of the dependent variable when the independent is zero.
SBr2 polar or nonpolar?
PBr3 is non-polar: the dipole moment of PBr3 is zero and therefor it is non-polar.
What are some uses of satellites orbiting the earth?
The difference is in the tilt of the plane of the orbit relative to the Earth's equator, which is zero for geostationary and 90 degrees for polar-orbit.
Why dipole moment is zero in non polar molecules non zero in polar molecules?
The dipole moment is zero in nonpolar molecules and non-zero in polar molecules due to electronegativity. Polar molecules have balanced electronegativity that will cancel one another out, while nonpolar molecules have unbalanced electronegativity causing dipole moments.
What does the y-intercept represent in a linear regression equation?
It represents the value of the y variable when the x variable is zero.
What is the condition for zero gravity?
freefall or stable orbit
Why do astronauts float weightlessly in space?
There is (apparent) zero gravity. The absolute gravity in orbit is about 90% of what it is on the surface of the earth, but the effective gravity is zero, and for a good reason.The fact is that in orbit, you are actually falling, but your forward speed is such that the curvature of the planet is dropping at the same rate that you are falling.And the astronauts are falling at the exact same speed as their capsule. This is called freefall.
Is NH3 has zero dipole moment?
NH3 is polar compound.So dipole moment is not zero.
