Answer:
He scored better on the second test by a margin of 3%.
Step-by-step explanation:
Find the percentage of each one by dividing Ahmed's score / Total possible score
24/30 = 0.8 > move the decimal place over twice for % > 80%
20/24 = 0.83333 > move the decimal place over twice for % > 83%
He scored 3% better on the second test.
Answer:
90
Step-by-step explanation:
10!/(10-2)!
n!=n(n-1)!
10•9•8!/(10-2)!
10•9•8!/8!
The 8! cancels out and you're left with 10•9
So, your answer is 90
Add 6x and 4x to make 10x
then it's 10x + 2 < 14
then subtract the 2 from the 14
10x< 12
divide 10
x< 12/ 10
simplify
x< 6/5 or 1 1/5
