Answer:
Mine has been good so far
Step-by-step explanation:
Answer:
as ratio of two type of fabric is different .
hence, the relationship between the number of square yards and the cost
is not proportional between the two types of fabric
Step-by-step explanation:
For a relation to be proportional
a:b = c:d
in other form
a/b = c/d
______________________________________________
Ratio for first type of fabric
cost of fabric/ area of fabric = 31.25/5 = 6.25
Ratio for other type of fabric
cost of fabric/ area of fabric = 71.50/11 = 6.5
as ratio of two type of fabric is different .
hence, the relationship between the number of square yards and the cost
is not proportional between the two types of fabric
Answer:
the mean is 62.8
Step-by-step explanation:
40 + 61 + 95 + 79 + 9 + 50 + 80 + 63 + 109 + 42 = 628
628 / 10 = 62.8
