Answer:
76$
Step-by-step explanation:
114=.6y; y= original price
y=190, original price
190-114=76
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.

The answer is (3,4). You just have to plug in the points into the equation to find which gives the matching y-value. So when you plug in 3, you get 2(3)-2 which is 4 (the y-value), hence (3,4) as the answer.
The answer is the second choice. First find the percentage of boys who prefer green which is 33%. Then find the percentage of girls who prefer red which is 36%.
Answer:
Slope: 1
y-intercept: 2
Step-by-step explanation:
(0,2) and (2,4)
Slope = (4-2)/(2-0) = 2/2 = 1
y-intercept: 2 - (1)(0) = 2
