marusya05 [52]

Answer:

Option B.

Step-by-step explanation:

In the question the number categories on the spinner are not given.

Consider there are 5 different categories on the spinner.

A = Spinner land on "Action".

So, probability of land on "Action" is

$P(A)=\frac{1}{5}$

Number of spins, n= 60 times

The expected number of land on "Action" is

$\text{Expected value}=n\times P(A)$

$\text{Expected value}=60\times \frac{1}{5}$

$\text{Expected value}=12$

Therefore, the correct option is B.

Point A is at (4,5) and lies on the graph of quadratic function f.

sveta [45]

We know that

g(x)=f(2x)
the transformation of f(x) to------------> f(2x)

means that point (a,b) in graph of f(x) becomes a point (a/2,b) in graph of f(2x)

therefore
point A (4,5)-----> becomes a point (4/2,5)-----> (2,5) in the graph of g(x)

the answer
the point is (2,5)
