It is 2/9
81. (9 to the power of 2 = 9 x 9).
2 |9| is 9 and |7| is 7 so 9-7 is 2
What is the abs value of X plus 2 less than 9?
To double the value of a fraction you need to quite literally multiply it by 2. For example, if you wanted to double the value of 5/9 you would multiply 5/9 by 2 (2/1) so it would be 10/9.
It is 2/9
-9 to 9. The range is the lowest value and the highest value.
81. (9 to the power of 2 = 9 x 9).
2 + 7 = 9
2 |9| is 9 and |7| is 7 so 9-7 is 2
What is the abs value of X plus 2 less than 9?
To double the value of a fraction you need to quite literally multiply it by 2. For example, if you wanted to double the value of 5/9 you would multiply 5/9 by 2 (2/1) so it would be 10/9.
3x+9/2=9 3x=9-9/2 3x=9/2 x=9/6 x=3/2
If 3z/2 = 9 then the value of z is 6
The value of 9 would be hundreds in this question the 4=thousands 9=hundreds 6=tens 2=ones
z=(x-mu)/s = (-10+9)/2 z = -1/2 Note that the standard normal has a mean of 0, therefore: The value of -10 is to the left of the mean of -9 The value of -1/2 is to the left of the mean of 0.
