Answer:
6.33
Step-by-step explanation:
Here, we are asked to give a residual value at x = 3
This mean we are to predict the value of y at the point x= 3
To do this, what we need to do is to input the value x = 3 into the line of best fit equation.
The line of best fit equation according to the question is;
y=0.331986x+5.33286
Substituting x here, we have
y = 0.331986(3) + 5.33286
y = 0.995958 + 5.33286 = 6.328818
Question asks to give answer to the nearest hundredth and that is 6.33
Answer:
A
Step-by-step explanation:
Going up increases the y coordinate, and going down decreases the y level. Going right increases the x coordinate, and going down decreases the x coordinate. Point B is going up by 2 - 1 = 1 and going right by 3 - 6 = -3 so point B is (-4-3,7+1) = (-7,8)
The slope-intercept form:
m - slope
b - y-intercept
<em>add x to both sides</em>
<em>divide both sides by (-2)</em>
It's a linear function.
We need only two points to plotting a graph.
We choose any three values of x and calculate y.
Answer:
2 : 3
Step-by-step explanation:
Given ratio of sides of 2 similar triangles = a : b , then
ratio of areas = a² : b²
Here by working in reverse
ratio of areas = 4 : 9 , thus
ratio of sides = : = 2 : 3
