\frac{\sum n}{n} = \frac{40 + 30 + 60 + 50 + 90 + 80}{6}

~ This yields 58.33 m/s.

How many boys are there in an introductory chinese course if 363 students are enrolled and there are six boys to every five girl
loris [4]

There are 198 boys in the introductory Chinese course

<h3>How to determine the number of boys?</h3>

The given parameters are

Total = 363

Ratio = Boys : Girls = 6 : 5

So, we have

Boys =6/(5 + 6) * total number of students

1) Jo Anne needs to do a speech in her English class that can't be more than 4 minutes
djyliett [7]

Answer:

( 0 < y < 23 / 6 ) mins

Step-by-step explanation:

Solution:-

We will define a variable ( x ) as the time it took for Jo Anne to give her speech at home.

The time taken to give her speech must always be less than 4 minutes. We can express this mathematically using an inequality as follows:

                              ( 0 < x < 4 ) minutes

Jo Anne gave her speech which was 10 seconds less than the one she practised at home. We will convert the time in seconds to minutes as follows:

                             10 s * \frac{min}{60 s}  = \frac{1}{6} min

The time taken by Jo Anne to complete her speech in English class can be represented as:

                             y = x - 1/6

Using the range of time that Jo Anne could take in delivering her speech in the class would be:

                                    0 < x < 4

                            0 - 1/6 < y < 4 - 1/6

                            -1/6 < y < 23 / 6

Since time can not be less than zero. We correct the lower limit to " 0 " as follows:

                              ( 0 < y < 23 / 6 ) mins
