Standard deviation : 
The formula to calculate z-score is given by :_
For x= 80, we have
The P-value = 
In percent , 
Hence, the approximate percentage of the test scores during the past year exceeded 80 =19.77%
Answer:
12 ounces-- hope this helps :))
Step-by-step explanation:
Answer:
The slope of the line 4x – 5y = 12 is m = 4/5.
Step-by-step explanation:
To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.
5 * 12 = 60 (for the whole area)
3 * 2 = 6 (for the missing space)
6 + 2 = 8
12 - 8 = 4
4 * 3 = 12
12 / 2 = 6
6 + 6 = 12
60 - 12 = 48
Answer: 48
Sorry if this isn’t right :(
Well just how many times. That doesn't make much sense
