Yes, parentheses can change the order in which operations are performed in an expression.
Let us understand this with two examples.
First example.
Let us suppose we have to simplify the expression
In this expression we have evaluated subtraction first instead of multiply.
Second example.
Let us suppose we have to simplify the expression
In this expression we have evaluated multiplication first and then subtraction.
Therefore, from above two examples we can see that parentheses can change the order in which operations are performed in an expression.
Answer:
6.98%
Step-by-step explanation:
To find relative frequency we divide frequency with the total number participants in that age bracket
Total number of participants age 10-19=172.....................given in the table
The frequence for those who ski at age 10-19=12---------------given in table
Relative frequency= 12/172 = 0.0697
Expressed as a percentage= 0.06976×100 =6.98%
Answer:
i might be wrong but it thinks it's 6 to 3 or 6/3
Step-by-step explanation:
because of the 6 , 3 are rarely encountered so it would be 6/3
Answer:
y=x^2-2
Step-by-step explanation:
It should be this one because if you have x squared it will be a parabola. A line should have a consistent slope. so Somethingx + y intercept =y
