(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.

Which graph shows the solution to the following inequality? 4d- 6 < 18 PLEASE HELP

kenny6666 [7]

Answer:

answer a

Step-by-step explanation:

$4d-6$ < $18$

Let's isolate $d$ on one side of the equation. Ignore the inequality for now. We'll deal with that later.

$4d-6=18\\4d-6+6=18+6\\4d=24\\\frac{4d}{4}=\frac{24}{4}\\ d=6$

Now, I'm going to bring back the inequality or < symbol. I only removed it when simplifying and isolating $d$ , but if this confuses you, just do your math and keep the inequality there.

$d$ < $6$

On a number line, this would include every number less than $6$ , due to the < (less than) symbol. This disqualifies answers b and d because they are showing every number greater than $6$ . But, how do we decide between answers a and c?
If a line has point at its beginning, $6$ , then that means that every number less than or equal to [ ≤ ] 6 is being shown, but our equation just says less than [ < ] 6, so answer a is our correct answer.
