Answer:900
Step-by-step explanation:
900/9=100
100x9=900
Multiply the z-score by the standard deviation:
2 x -1.5 = -3
Now add that to the mean:
49 + -3 = 46 inches.
Let the number = x.
So 2 times x subtracted from 11 is written as 11-2x
The result is 4 more than the number is written as 4 +x
Now you have 11-2x = 4 + x
We can now solve for x.
Add 2x to each side:
11 = 4 + 3x
Subtract 4 from each side:
7 = 3x
Divide both sides by 3:
x = 7/3
Answer:
I believe the answer is n/3 + 15n.
