A group of seventh graders and a group of teachers at a local middle school were asked how many siblings they each have. The dot
dimulka [17.4K]

Answer:

A. The students tend to have fewer siblings than the teachers.

Step-by-step explanation:

First we need to draw the dot plots correctly. If you count both sides they have 20 each.

Now, clearly none have fewer nobody here yet has more or less but going on to the next step.

Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14.  And so on.

On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.

So the answer is A. The students tend to have fewer siblings than the teachers.

Answer:

425 mm


Step-by-step explanation:

The ratio of compound A to compound B is 5 is to 6.

So, we can say that the total ratio is of 11 parts (5+6=11).

<em><u>If the chemist wants a total of 935 mm of the drug, then each of the 11 parts are worth:</u></em>

\frac{935}{11}=85


<em>From the ratio, we know that Compound A is 5 parts. So:</em>

85*5=425

425 mm of Compound A is needed.
