Answer:
0.08
Step-by-step explanation:
Please use parentheses to indicate which operations must be done first. I 'm choosing to believe that you meant 7^(3x-1) and 5^(x-1).
Taking the common log of both sides, we get:
(3x-1)log 7 = (x-1)log 5
Then 3x·log 7 - log 7 = x log 5 - log 5
Grouping the x terms:
x(3·log 7 - log 5) = log 7 - log 5. We combine log 7 and log 5, obtaining log (7/5).
Then x(3·log 7 - log 5) = log (7/5).
Solving for x:
log (7/5)
x = ---------------------
3·log 7 - log 5
0.1461
x = ------------- = 0.08
1.0363
This agrees with the 3rd answer choice.
Answer:
The correct answer is Non-representative.
Explanation:
When a non-representative study is conducted. The researchers face or seek random samples in order to make their studies. On the other hand, a representative study is conducted with the purpose of looking for more specific or accurate samples.
Y +6 =(1/2)(x+4)
y +6 = 1/2 x +2
y=1/2 x - 4
or 1/2 x -y = 4
The answer: 1.2
Work:
2 equations: 150=100% and x=0.8%
Combine these
150/x=100/0.8
150= 125x
X=1.2
