Solution:
Average time per line = total time / total lines
Average time per line = (3x^2 + 2)/(x + 4)
Average time per line = 3x - 12 + (3x^2 + 2)/50 milliseconds
Answer:
Step 2: 4 ( 2 ) + 4 ( 3 x )
Step-by-step explanation:
The student didn't factorise 8 x + 12 properly
Answer:
5040
Step-by-step explanation:

Answer:
Bob performed better in mathematics part of the SAT than the ACT
Step-by-step explanation:
We need to calculate the z-scores for both parts and compare them.
Z-score for the SAT is calculated using the formula:
where 
is the mean and 
is the standard deviation, and 
is the SAT test score.
We plug in these values to obtain:
to the nearest hundredth.
We use the same formula to calculate the z-score for the ACT too.
Where 
is the mean and 
is the standard deviation, and 
is the ACT test score.
We substitute the values to get:
to the nearest hundredth.
Since 1.29 > 1.25, Bob performed better in mathematics part of the SAT
