Answer:
.
Step-by-step explanation:
It is given that a number, x, rounded to 2 significant figures is 1300.
It is possible if,
1. The value of x is greater than of equal to 1250 and less than or equal to 1300.
i.e.,
...(1)
2. The value of x is greater than of equal to 1300 and less than 1350.
i.e.,
...(2)
On combining (1) and (2), we get

1350 is not included in the error interval for x.
Interval notation is
.
Therefore, the error interval for x is
.
Step-by-step explanation:
Solution given;
cost price=Rs125
profit%=?
we have
profit%=[Selling price-cost price]/cost price×100%
=[selling price-Rs.125]/Rs 125×100% is your answer

Answer:
12:28 = 3:7
Step-by-step explanation:
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 12 and 28 is 4
Divide both terms by the GCF, 4:
12 ÷ 4 = 3
28 ÷ 4 = 7
The ratio 12 : 28 can be reduced to lowest terms by dividing both terms by the GCF = 4 :
12 : 28 = 3 : 7
Therefore:
12 : 28 = 3 : 7
