9. To be proficient it requires 50% to pass. If Andrew gets 280 points and
falls short by 20 points, what were the maximum points Andrew could have
got?

600

Step-by-step explanation:

Andrew has 280 points. We are told that he is 20 points short of 50% proficiency.

280 + 20 = 300

Now we know that 300 is 50% of the maximum amount of points.

As 50% is equal to 1/2, we know that 300 is 1/2 of the total. To find the total, we must double 300, resulting in 600.

Hope this helps!

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
