Answer:
1/2
Step-by-step explanation:
(1/16)^x
Let x = 1/4
(1/16)^ 1/4
Rewriting 16 as 2^4
(1/2^4)^ 1/4
We know that 1 / a^b = a^-b
(2 ^ -4)^ 1/4
We know that a^b^c = a^(b*c)
2^(-4*1/4)
2^-1
We know that a^-b = 1/ a^b
2^-1 = 1/2^1 = 1/2
Answer:

Step-by-step explanation:
The fraction of bran muffins is expressed as bran muffins over total muffins.
Total muffins = 6 + 2 + 4 = 12 and bran muffins = 4, thus

Hi!
First, find the total percent of vehicles with at least 3 people.
15% + 7% + 3% = 25%
Now find 25% of 420
Set up a proportion and cross multiply to solve.

25 * 420 = 10500
10500/100 = 105
The answer is 105 vehicles contained at least 3 people.
Hope this helped! :)
