ANSWER: ABC and probably e but not sure about that one
EXPLANATION:
A proportional relationship is a relation between two quantities in which the ratio of one quantity to the other quantity is constant… hope this was helpful ;)
(1) The stem and leaf plot is a table organized by the first few (stem) digits with leaves (the rest digits) listed in corresponding rows. The solution depend on how your teacher expects stems to be defined (how many digits). Here's a link describing how to construct them. It is fairly straight-forward. https://www.mathsisfun.com/data/stem-leaf-plots.html
(2) the distribution (see image) is not really strictly symmetric. so I would choose (B)
(3) the distribution (see 2nd image) might be seen as "roughly normal" especially looking at the available options, choice (C) is the only plausible.
Proof by contradiction!
hope i helped
Answer:
1/30 as a fraction and 0.03 repeatedly as a decimal
Step-by-step explanation:
Answer:
y = -2/5x + 13
Step-by-step explanation:
First you should find the slope of the line on the graph. You move to the right 4 points and up 10 points. Since we write slope as rise over run you would get that m= 10/4 or 5/2
Now plug in the points and slopes into point slope form. y+2 = 5/2 (x+6)
We distribute y+2= 5/2x + 15
We subtract two to the other side y = 5/2x + 13
Now we have the equation of our line. To find the equation of the line PERPENDICULAR we flip our slope fraction and change the sign so our new slope will be m = -2/5
therefore, our equation will be y = -2/5x + 13
