Answer:
This is really easy it's D
Step-by-step explanation:
Answer: y = 1.2x + 1.4
Step-by-step explanation:
1. Write down the coordinates of the first point. Let's assume it is a point with x₁ = -2and y₁ = -1.
2. Write down the coordinates of the second point as well. Let's take a point with x₂ = 3 and y₂ = 5.
3. Use the slope intercept formula to find the slope:
m = (y₂ - y₁)/(x₂ - x₁) = (5-1)/(3-2) = 4/1 = 1.2
4. Calculate the y-intercept. You can also use x₂ and y₂ instead of x₁ and y₁ here.
b = y₁ - m * x₁ = -1 - 1.2*-2 = 1.4
5. Put all these values together to construct the slope intercept form of a linear equation:
y = 1.2x + 1.4
The answer is B. 4.2. I did a test and the answer was B.
Answer:
a. probability, when the null hypothesis is true, of obtaining a sample result that is at least as unlikely as what is observed
Step-by-step explanation:
In Statistics, a p-value also known as the probability value is the probability, when the null hypothesis is true, of obtaining a sample result that is at least as unlikely as what is observed.
The p-values can be calculated by using spreadsheets, statistical software and p-value tables and is widely used in research fields such as economics, physics, sociology, accounting etc.
The p-value can be mathematically expressed as a function of the null hypothesis, H and the random variable, X.
