18. Use the spinner to find each theoretical probability

solong [7]

In the spinner there are eight numbers numbered from 1 to 8. To solve this problem, we must remember that probability is:

Probability = number of successful events / number of total events

a. P (even number). There are 4 even numbers, therefore the probability is:

P (even number) = 4 / 8

P (even number) = ½ = 0.5 = 50%

The probability of getting an even number is 50%.

b. P (a number greater than 3). There are 5 numbers greater than 3, therefore the probability is:

P (number greater than 3) = 5 / 8

P (number greater than 3) = 0.625 = 62.50%

The probability of getting a number greater than 3 is 50%.

c. P (an odd number). Similar to the even number, there are 4 odd numbers. Therefore,

The probability of getting an odd number is 50%.

Justine graphs the function f(x) = (x – 7)2 – 1. On the same grid, she graphs the function g(x) = (x + 6)2 – 3. Which transforma

qwelly [4]

For a parabola of the form $y=(x-h)^2+k$ , its vertex is located at (h, k).
The vertex of f(x) is at (7, -1).
The vertex of g(x) is at (-6, -3).
To move (7, -1) to (-6, -3), we would have to go 13 units to the left and 2 units down. Therefore, moving f(x) 13 units left and 2 units down would map it onto g(x).
