You would do 8 / (2/3).
The answer is 12
In this item, we have the mean incubation period of 23 days and the standard deviation is 22 days. We use z-score to determine the unknown in each of the items.
(a) less than 21 days.
z-score = (23 - 21) / 22 = 1/11
This translates to a percentage of 53.6%
(b) z-score for 19 days.
z-score = (23 - 19) / 22 = 2/11
This translates to a percentage of 57.2%.
z-score for 23 days.
z-score = (23 - 23)/ 22 = 0
This translates to a percentage of 50%.
The difference between the two numbers is only 7.2%
(c) z-score of 25.
z-score = (23 - 25)/ 22 = -1/11
This translates to a percentage of 42.3%.
Then, subtract this value from 100 to give us the final answer of 57.2%.
13a - 2 is the answer, because 16(a-2) become 16 - 32, not 16a - 14.

The value of the expression (12/2)×| 1.3 - 2.16 | is 5.16 .
The Absolute Value of a number means writing the number without the negative sign .
For Example : the absolute value of -2 is |-2| = 2
In the question ,
an expression in words is given as "12 divided by 2 x the absolute value of 1.3 minus 2.16 "
the above expression in numbers can be represented by
= (12/2)×| 1.3 - 2.16 |
= 6 × | 1.3 - 2.16 |
= 6 × |-0.86|
= 6 × 0.86 .... because |-0.86| = 0.86
= 5.16
Therefore , The value of the expression (12/2)×| 1.3 - 2.16 | is 5.16 .
The given question is incomplete , the complete question is
Find the value of the expression " 12 divided by 2 x the absolute value of 1.3 minus 2.16 " ?

Answer:
70°
Step-by-step explanation:
All triangles' angles are added up to 180°
30 + 80 + x = 180
110 + x = 180
x = 180 - 110
x = 70
