Answer:
In mathematics, we call this making predictions using random sampling. We basically take data from a random sample of a population and make predictions about the whole population based on that data.
Step-by-step explanation:
Let 77$ be x percent of 7,000$.
so
so the fee is 1.1% of the cost.
This means the fee for a car costing 9,200$ is
$
The complete transformation is Rk, where k is the line with equation x = 2
<h3>How to complete the transformation?</h3>

From the attached graph, we can see that the triangle and its image have a common vertex at C.
This means that the triangle is reflected across a vertical line that passes through point C.
The coordinate of C is:
C = (2, -2)
The vertical line passes through the x-coordinate.
So, we have:
x = 2
Hence, the complete statement is:
The complete transformation is Rk, where k is the line with equation x = 2

Answer:
x=500
Step-by-step explanation:
To solve the equation given, we will follow the steps below:
log 20x³ - 2log x=4
using the law of logarithm,
2log x = log x²
so, our equation becomes;
log 20x³ - log x²=4
Also using another law of logarithm;
log 20x³ - log x² = log (20x³/x²)
our equation becomes;
log (20x³/x²) = 4
log 20x = 4
from the definition of logarithm, logarithm is the power of the exponential
10⁴ = 20 x
10000 = 20x
divide both-side of the equation by 20
10000/20 = 20x/20
at the right-hand side of the equation 20 will cancel-out 20 leaving us with just x and the left-hand side of the equation, 10000 will be divided by 20
500 = x
x = 500
