There are two black queens in a standard deck, so the probability is 2/52 or 1/26.

If instead you know you pulled a black card from the deck and you’re wondering what the probably is that it’s a queen, then it’s 2/26, since there are still 2 black queens, but only 26 black cards.

Shown here is the graph of a function f.

vazorg [7]

Answer:

C) They are the same.

Step-by-step explanation:

The function f(x) has points as per graph:

f(1) = 9
f(3) = 1

So the points are:

(1, 9) and (3, 1)

Rate of change for f(x):

(1-9)/(3-1) = - 8/2 = -4

The function g(x) has points:

g(1) = -1² + 10 = 9
g(3) = -3² + 10 = 1

So the points are:

(1, 9) and (3, 1)

Rate of change for f(x):

(1-9)/(3-1) = - 8/2 = -4

As we see both functions have same rate of change over the interval [1, 3]

The answer choice is: C) They are the same

How can the transformation shown be described? Check all that apply. dilation isometric transformation nonrigid transformation r

sasho [114]

Answer:

C). Nonrigid transformation.

F). Stretch

Step-by-step explanation:

Transformation in mathematics is defined as the alteration or variation in the shape of an object without altering the lengths by using a flip, turn, slide, or resizing.

The transformation 'Hexagon ABCDEF → hexagon A'B'C'D'E'F'' would best be described as the 'non-rigid' and 'stretch' transformation. Non-rigid because it alters the shape or size of the figure both vertically as well as horizontally. It would be considered a stretch transformation as it is resized by a pull from both the vertical and horizontal angles. Thus, options C and F are the correct answers.
