Answer:

(-6,5)

Step-by-step explanation:

we have

y=f(x) ----> the parent function

y=1/2f(x) ---> the new y-value will be 1/2 times the original value

The rule of the transformation of f(x) to 1/2f(x) is

(x,y) -----> (x,y/2)

substitute the given value

(-6,10) ------> (-6,10/2)

(-6,10) ------> (-6,5)

The two-way table shows the number of books of each type in Eliza's home what is the probability that a randomly selected refer

Salsk061 [2.6K]

Answer:

B. 0.4

Step-by-step explanation:

Use the definition of the probability

$Pr=\dfrac{\text{Number of all favorable outcomes}}{\text{Number of all possible outcomes}}$

You have to find the probability that a randomly selected reference book is hard cover. Hence, from the table

Number of all possible outcomes = Number of Reference books = 25
Number of all favorable outcomes = Number of Hardcover Reference books = 10

So, the probability is

$Pr=\dfrac{10}{25}=\dfrac{40}{100}=0.4$
