The answer is n^3×2^(n+1)
Answer:
0.62
Step-by-step explanation:
There are a total of 10 marbles in the bag.
P(blue and not blue) = 5/10 × 5/10 = 25/100
P(red and not red) = 2/10 × 8/10 = 16/100
P(green and not green) = 3/10 × 7/10 = 21/100
P = 25/100 + 16/100 + 21/100
P = 62/100
P = 0.62
Alternatively, you can calculate it this way:
P(both blue) = (5/10)² = 25/100
P(both red) = (2/10)² = 4/100
P(both green) = (3/10)² = 9/100
P = 1 − (25/100 + 4/10 + 9/100)
P = 1 − 38/100
P = 62/100
P = 0.62

Answer:
i need the answer too :(
Step-by-step explanation:
From 1st condition:
3^(x+1)=81
Take log on both sides,
➡ log [3^(x+1)]=log81
Use the property: log(x^a)=a logx
➡ (x+1) log 3=log(3⁴)
➡ (x+1) log 3=4×log 3
➡ (x+1)=4 (log 3 /log 3)
➡ x+1=4
➡ x=3➡↪➡↪ ANS
From 2nd condition, (Same process are repeated)
81^(x-y)=3
➡ 3^4(x-y)=3
➡ log [3^4(3-y)]=log 3
➡ 4(3-y) log 3=log 3
➡ (3-y)=(log 3)/(4log 3)
➡ 3-y=(1/4)
➡ y=11/4 ➡↪➡↪ ANS
