It is known as Statistical Inference.
Statistical Inference
- Without sampling and statistical estimation of the value, some population parameters cannot ever be known. Take customer preference samples, for instance. Since asking everyone would be impractical, choose a sample to identify the parameter.
- A population's mean can be estimated quite well using the confidence interval. It offers a spectrum of values that most likely includes the population mean. The interval gets smaller as sample size increases.
- The method of ordinary least squares is used in a regression equation to develop an equation that best fits the data of an independent variable and dependent variable.

To find the lengths of a right triangle, we can use what is called Pythagorean Theorem: a^2 + b^2 = c^2, where a and b are the legs of the triangle and c is the hypotenuse.
13^2 + b^2 = 17^2
169 + b^2 = 289
b^2 = 120
b = 11.0 cm
The length of the other leg of the triangle is 11.0 cm (rounded).
Hope this helps!
K12 if you know plzz tell me too
Primarily, horizontal lines mean zero slope. Therefore the equation is y= 3 because you are only left with the y-intercept at this point. The rate of change is another way of saying slope. Function 2's slope is 5 and function 1's slope is 0. Therefore, the rate of change of function 2 is greater than the rate of change of function 1 by 5.
5 is the answer.
hope this helps :)
Distance of earth from the sun = 1.5 x 10⁸ km
speed of light = 3 x 10⁸ m/s
time in minutes = ?
by using the formula,
Distance = velocity x time, we get
time = distance/velocity
time = t = (1.5 x 10⁸) / (3 x 10⁸) = 0.5 seconds
convert 0.5 seconds to minutes = 0.00833333
it takes 0.00833333 minutes to travel from the sun to the earth
