Answer:

g(x) = (x-a,-y - b)

Step-by-step explanation:

Given

Represent f(x) as follows:

f(x) = (x,y)

Transformations:

Horizontally shifted right by a

Reflected across x axis

Vertically shifted down by b

Taking the transformations one after the other.

Horizontally shifted right by a

When a function is shifted right, the resulting function is:

f' = (x-a,y)

Reflected across x axis

Here, the x axis remains unaltered while the y axis is negated

f' = (x-a,y)

becomes

f" = (x-a,-y)

Vertically shifted down by b

When a function is shifted down by b, the resulting function is:

f"' = f" - b

i.e, subtract b from the function (f(x) or y, as the case may be)

So, we have:

f"'  = (x-a,-y - b)

Represent f"' with g(x)

g(x) = (x-a,-y - b)

Two dance teams, the Roses and the Tulips, are perfectly matched so that their chances of winning are both set at 50%. What is t
shtirl [24]

Answer:

6%

Step-by-step explanation:

Step 1

The fist step is to define the probabilities.

The events are independent from each other. Each team wins with probability \frac{1}{2} and looses with probability \frac{1}{2}.  Let P(W_R) be probability that Roses win and P(L_R)  be the probability that Roses loose.

Step 2

The second step is to calculate the probabilities by multiplying the probabilities with the first 3 terms in the product being the probability of a win and the last term being the probability of a loss.

The calculation is shown below,

P(W_R)\times P(W_R)\times P(W_R)\times P(L_R)=\frac{1}{2} \times \frac{1}{2} \times\frac{1}{2} \times\frac{1}{2} =\frac{1}{16}

Step 3

The last step is to convert this probability into a percentage. Converting this probability to a percentage is  done as shown below,

\frac{1}{16} \times 100\%=6.25\%.

Step 4

The next step is to round down the percentage . The value of 6.25% rounded down is 6%. The correct answer is 6%.
