Applying the definition of a linear pair, m∠TOS = 52°
<em>Recall:</em>
Linear pair are two angles on a straight line whose sum equals 180°.
Given:
- m∠TOU = 128°
- m∠SOV = (4x + 8)°
m∠TOU + m∠TOS = 180° (linear pair)
128° + m∠TOS = 180°
- Subtract 128° from both sides of the equation
m∠TOS = 180° - 128°
m∠TOS = 52°
Thus, applying the definition of linear pair, m∠TOS = 52°

Step-by-step explanation:
You need to find out how many spring rolls will feed a single person
then use this to multiply by two if you want number of rolls, or divide by two if you want to get number of people that can be fed.
Assuming you know the mean (mu) and the standard deviation (sigma), you would use the raw score (x) to get the z score through this formula
z = (x-mu)/sigma
If you get a positive z value, then the raw score is above the mean. If z is negative, then the raw score is below the mean.
The absolute value of z tells us how far away from the mean we are in terms of standard deviation.
Eg: z = -3 leads to |z| = |-3| = 3, so we're 3 standard deviations below the mean.
