<h3>
Answer: 4/5</h3>
Explanation:
We have 24 adults who passed and 16 teens who passed. So 24+16 = 40 people passed total.
There are 24+8+16+2 = 50 people total
If you pick someone at random, the probability of them passing is 40/50 = 4/5.
In decimal form, this is 4/5 = 0.80 which converts to 80%
The answer should be 6 I.e 6^1 as with indices rules you need to subtract the powers (-3-(-4)) which equals 1

Answer:
Step-by-step explanation:
=7 (1+11+111+1111......n)
=7/9 (9+99+999+9999....n)
=7/9 ((10-1)+(10^2-1)+(10^3-1)+....n)
=7/9 ((10+10^2+10^3...n)-(1+1+1+1.....n))
=7/9 ((10 (10^n-1)/(10-1))-n)
