Well I’m guessing it went down by 20% to get to thirty pounds so
30 x 1.2 = $36 original price
Or if it’s lowered by 20% then
30 x 0.8 = $24
increase in x results in the decrease in y
Answer:
A,B,E
Step-by-step explanation:
Just did completed this on Ed
Clusters are when data is very close together therefore graphs 2 and 3 have clusters. The data doesn’t seem to fit the regression line very well like figure 4.
Outliers in data or scatter plots are when values are very separated form each other therefore scatter plot 1 is the only one that has outliers. It has blue dots that are very separate from its regression line.
Figure four doesn’t fit any of the questions asked.
Hope this helps!
Answer:
See explanation below to use the vertex form to solve a quadratic equation.
Step-by-step explanation:
(x - h)^2 - k = 0, the vertex is (h, -k)
An example below, taking a quadratic equation and completing the square:
x^2 - 2x - 1 = 0
x^2 - 2x = 1
(-2/-2)^2 = 1, add 1 to both sides of the equation.
x^2 - 2x + 1 = 1 + 1
(x - 1)^2 = 2
(x - 1)^2 - 2 = 0
The vertex is (1, -2)
