36 minutes.
(1/20)x+(1/30)x=1solve for x (x=0.8333333333......)
Considering they take the same times for all 3 pounds,
That would mean that since 1 pound takes 12 minutes, then 3 pounds take 36 minutes
Answer: Option b.
Step-by-step explanation:
1. You can rewrite it as following:
This means that you must substitute x=-6 into the limit. There is not x, then the function is always equal to 2, no matter the value of x.
This means that you must substitute x=-6 into the limit. There is not x, then the function is always equal to 1, no matter the value of x.
2. Then:
3. The answer 2.
<span>Mean = 270
Standard deviation = 10
x = 255
Formula for z-score, z = (x - mean)/SD
z = (255 - 270) / 10
=> z = -15 / 10 => z = -1.5
So by referring to z-table, -1.5 correlates to 0.0668 that implies to 0.07
So 7% of the boxes of Apples weight less than 255oz.
The percentage of boxes is in the range of 255 oz and 270 oz,
Now calculating the requiring percentage 50% - 7% = 43%</span>
