The experimental probability of the coin landing heads up is 110/200 = 11/20.
The theoretical probability is 1/2

The chart below lists the original and sale prices of items at a clothing store.
Tom [10]

Answer: C) For every original price, there is exactly one sale price.

For any function, we always have any input go to exactly one output. The original price is the input while the output is the sale price. If we had an original price of say $100, and two sale prices of $90 and $80, then the question would be "which is the true sale price?" and it would be ambiguous. This is one example of how useful it is to have one output for any input. The input in question must be in the domain.

As the table shows, we do not have any repeated original prices leading to different sale prices.

Which function represents g(x), a reflection of f(x) = On a coordinate plane, 2 exponential functions are shown. g (x) decreases
Vanyuwa [196]

Answer:

g(x)=\frac{1}{2}(3^{-x})

Step-by-step explanation:

Given:

The graph of function f(x)\ and\ g(x) are given.

The equation for f(x) is given as:

f(x)=3^x

Now, the graph of g(x) is a reflection of f(x).

The graph of g(x) passes through the point (-1, 1.5) [second quadrant] and crosses the y-axis at (0, 0.5).

As evident from the graph, the functions f(x)\ and\ g(x) are reflections about the y-axis.

We know the transformation rule for reflection about the y-axis as:

f(x)\to f(-x)\\\\\therefore 3^x\to3^{-x}....(\textrm{Reflection about y-axis})

Now, the y-intercept of the function y=3^{-x} is obtained by plugging in x=0. This gives,

y=3^0=1

So, the y-intercept is at (0, 1). But the graph of g(x) crosses the y-axis at (0, 0.5). As we observe, the coordinate rule for the transformation can be written as:

(0, 1) → (0, 0.5)

(x,y)\to (x,\frac{1}{2}y)

So, the reflected graph is compressed vertically by a factor of \frac{1}{2}.

Therefore, the transformation is given as:

y\to \frac{1}{2}y\\\\\therefore 3^{-x}\to \frac{1}{2}(3^{-x})

Therefore, the equation for g(x) is:

g(x)=\frac{1}{2}(3^{-x})
