Answer:
You can use the scale factor to determine if a picture is an enlargement if the scale factor is greater than 1. If it is less than 1 like 0.9 then the picture would be a reduction because you would be multiplying the number by a number smaller than 1. Now if we have a scale factor greater than 1 let's say 3. Then the picture would be an enlargement because the number is greater than 1.

Answer:
Less than 30: 26
Less than 40: 62
Less than 50: 75
Less than 60: 78
Less than 70: 85
Less than 80: 86
Less than 90: 88
Step-by-step explanation:
We have this frequency information:
20-29: 26
30-39: 36
40-49: 13
50-59: 3
60-69: 7
70-79: 1
80-89: 2
We can add each category and have a cumulative frequency table
<30: 26
<40: 26+36 = 62
<50: 62 +13 = 75
<60: 75 + 3 = 78
<70: 78 + 7 = 85
<80: 85 + 1 = 86
<90: 86 + 2 = 88
