Answer:

\frac{1}{3}

Step-by-step explanation:

A point (x, y) with integer coordinates is randomly selected such that 0 \le x \le 8 \:and\: $0 \le y \le 4$.

The possible pairs of (x,y) are:

(0,0),(0,1),(0,2),(0,3),(0,4)

(1,0),(1,1),(1,2),(1,3),(1,4)

(2,0),(2,1),(2,2),(2,3),(2,4)

(3,0),(3,1),(3,2),(3,3),(3,4)

(4,0),(4,1),(4,2),(4,3),(4,4)

(5,0),(5,1),(5,2),(5,3),(5,4)

(6,0),(6,1),(6,2),(6,3),(6,4)

(7,0),(7,1),(7,2),(7,3),(7,4)

(8,0),(8,1),(8,2),(8,3),(8,4)

The Total Possible Outcomes n(S)= 45

The pair (x, y) that satisfies the given condition (say event A: x + y \le 4) are:

(0,0),(0,1),(0,2),(0,3),(0,4)\\(1,0),(1,1),(1,2),(1,3)\\(2,0),(2,1),(2,2)\\(3,0),(3,1)\\(4,0)

n(A)=15

Therefore:

P(A)=\frac{n(A)}{n(S)} =\frac{15}{45} =\frac{1}{3}

The graph shows f(x)=(1/2)and its translation, g(x).
san4es73 [151]

The translation of four units up describes the transform function g(x) option first is correct.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

The question is incomplete.

The question is:

The graph shows f(x)=(1/2)ˣ and its translation, g(x).

Which describes the translation of f(x) to g(x)?

  • Translation of four units up
  • Translation of five units up
  • Translation of four units to the right
  • Translation of five units to the right

The graph is attached please refer to the picture.

We have the equation of the function f(x):

\rm f(x) = (\dfrac{1}{2})^x

From the graph, we can see the graph of the function f(x) is shifted up 4 units because the y-intercept of the graph g(x) is (0, 5)

g(x) = f(x) + 4

\rm g(x) = (\dfrac{1}{2})^x + 4

Thus, the translation of four units up describes the transform function g(x) option first is correct.

If a marble rotates 180 degrees in 9 seconds, how many does it rotate in 18 seconds.
Troyanec [42]
It would rotate 360 degrees because 18 seconds is twice the amount of 9 seconds, so you need to multiply 180 by 2, which is 360, or one full rotation.

10. A shape is made of 5 right triangles of equal size. Each triangle has a base of 7 cm and a height of 4 cm. What is the total
Oliga [24]

Answer:

Option C - 70 cm²

Step-by-step explanation:

Area of a right angle triangle is given by the formula :

A = 1/2×h×b

A = 1/2×7×4

A = 1/2×28

A = 14

This is the area of 1 right angle triangle. The area of 5 will be

14×5 = 70

Units will be cm²

Please tell me answer quick
Fittoniya [83]

Answer:

If you look at the picture from my point of view it would be the top left box and the top middle box. Both have 10 boxes in them and you need three shaded in for half of that box, so if you have 10 boxes you will need 6 shaded in. Hope this helped.
