We can write this as a proportion
68/4 = x/30
cross multiply
68 * 30 = 4x
2040  = 4x
divide both sides by 4
510 = x

It can print 510 letters in 30 seconds.

Hope this helps :)

Kellan collected two sets of data and recorded them in the table. 
tigry1 [53]

Answer:

Set 2 has a wider spread and has range of 27

Explanation:

We are given the below two sets of data:

Set 1             Set 2

17                     81

13                     70

18                     94

24                     68

21                      95

Now, let's find the range of Set 1:

Range=Maximum-Minimum

        =24-13

        =11

Now, let's find the range of Set 2:

Range= Maximum -Minimum

        =95-68

        =27

Since, the Set 2 has more range, therefore, Set 2 has a wider spread and a range of 27
