Answer:
- m = -3/4
- y-intercept = 399
- slope-intercept equation: y = -3/4x + 399
Step-by-step explanation:
It can be easiest simply to solve the equation for y.
3x + 4y = 1596
4y = -3x + 1596 . . . . subtract 3x
y = -3/4x + 399 . . . . divide by 4
From this equation in slope-intercept form you can read the slope as -3/4 and the y-intercept as 399. You already know the equation.
Answer:
In a one-way ANOVA, the
is calculated by taking the squared difference between each person and their specific groups mean, while the
is calculated by taking the squared difference between each group and the grand mean.
Step-by-step explanation:
The one-way analysis of variance (ANOVA) is used "to determine whether there are any statistically significant differences between the means of two or more independent groups".
The sum of squares is the sum of the square of variation, where variation is defined as the spread between each individual value and the mean.
If we assume that we have p groups and each gtoup have a size
then we have different sources of variation, the formulas related to the sum of squares are:

A measure of total variation.

A measure of variation between each group and the grand mean.

A measure of variation between each person and their specific groups mean.
Which set of ordered pairs represents a function? {(2, –2), (1, 5), (–2, 2), (1, –3), (8, –1)} {(3, –1), (7, 1), (–6, –1), (9, 1

A function can't have x repeating any of the same number twice for example the first one (2, -2), (1, 5), (-2, 2), (1,-3), (8,-1) you have two 1's (1,5) and (1,-3) the x is the first number. Now a function can have the same y value. So your answer is (3, -1), (7,1), (-6,-1), (9,1), and (2,-1) you have to have all different x values in order for it to be a function. Hope that helps.
Answer:(1, -3).
Step-by-step explanation:
If y=2x-5 is equation (1) and 4x-y=7 is equation (2), then substitute equation (1) in equation (2):
4x - (2x - 5) = 7
4x - 2x + 5 = 7
2x = 7-5
2x = 2
x = 1
Now substitute the value of x in equation (1) to find the value of y:
y = 2 (1) - 5
y = 2 - 5
y = -3
