Answer:

The correct answer to the following question will be "0.19".

Step-by-step explanation:

A correlation seems to be a statistical measure of how well the evidence matches the best comment. The better or larger the correlation, the stronger the match, through to 1.0 or -1.0. A positive relationship between the two indicates a growing statistical model, although a negative correlation or confidence interval suggests a down set of data.
Value varies from -1.0 to 1.0. A significance level of 0.05 indicates less than -1.0 indicates that there had been a mistake throughout the calculation of correlation.

So that the above seems to the right answer.

line 1 passes through (2,2) and (5,5). line 2 passes through (3,-6) and (-5,2). Are the lines parallel or perpendicular?

Gelneren [198K]

Find the slope of the first line, that is the difference of the y’s over the difference of the x’s. This way: 2-5/2-5=-3/-3 which equals 1
Now find the slope of the second line 2-(-6)/-5-3
=8/-8
=-1
The slopes are opposite reciprocal ( you could also say that the product of the 2 slopes equals -1) therefore the lines are perpendicular.

Analyze the key features of the graph of the quadratic function f(x) = –x^2 + 4x – 3.

Answer:

down
maximum
x=2; (2, 1), -3

Step-by-step explanation:

1. The negative leading coefficient (-2) tells you the parabola opens downward.

2. The fact that the parabola opens downward tells you the vertex is a maximum.

3. For quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a). For this parabola, that is x = -4/(2(-1)) = 2. The y-value of the vertex is f(2) = -2^2+4(2)-3 = -4+8-3 = 1. The y-intercept is the constant, c = -3.

axis of symmetry: x = 2
vertex: (2, 1)
y-intercept: (0, -3)
