Answer:

Therefore, the four intervals are

(1)    6 - 6.59

(2)   7 - 7.59      

(3)    8 - 8.59      

(4)    9 - 9.59

The four frequencies are

(1)   4

(2)   3

(3)   1    

(4)  6

Step-by-step explanation:

From the data, we have

                     Interval                                                       Frequency

1st                 6 - 6.59                                                        4

2nd               7 - 7.59                                                        3

4th                 9 - 9.59                                                       6

Therefore, the four intervals are

(1)    6 - 6.59

(2)   7 - 7.59      

(3)    8 - 8.59

Kalani had a length of 3 1/3m of cloth and cut 2 5/12 strips the full width of the cloth. Let l represent the length, in meters,
Vesna [10]

The multiplication and division equations to represent the relationship are 2 5/12 * l = 3 1/3 and 3 1/3 ÷ 2 5/12 = l

<h3>How to select 1 multiplication and 1 division equation to represent relationship?</h3>

The given parameters are:

Length = 3 1/3 m

Strip = 2 5/12

The length in meters of each whole strip is represented as l

So, we have:

Length ÷ Strip = l

Substitute the known values in the above equation

3 1/3 ÷ 2 5/12 = l

Divide both sides by 2 5/12

2 5/12 * l = 3 1/3

Hence, the multiplication and division equations to represent the relationship are 2 5/12 * l = 3 1/3 and 3 1/3 ÷ 2 5/12 = l
