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).

Consider this system of equations. Which shows the second equation written in slope intercept form?
lora16 [44]

Answer: Second option.

Step-by-step explanation:

The Slope-Intercept form of the equation of the line is:

y=mx+b

Where "m" is the slope of the line and "b" is the y-intercept.

You know that the second equation of the System of equations given in the exercise is:

10(x+\frac{3}{5})=2y

Then, you need to solve for the variable "y" in order to write it in Slope-Intercept form. The steps are:

1. Apply the Distributive property and simplify:

10x+\frac{30}{5}=2y\\\\10x+6=2y

2. Now subtract 6 from both sides of the equation:

10x+6-6=2y-6\\\\10x=2y-6

3. Subtract 2y from both sides of the equation:

10x-2y=2y-6-2y\\\\10x-2y=-6

4. Subtract 10x from both sides:

10x-2y-10x=-6-10x\\\\-2y=-10x-6

5. Divide both sides by -2:

\frac{-2y}{-2}=\frac{-10x-6}{-2}\\\\y=5x+3

ahrayia [7]

Answer:

  $1.65

Step-by-step explanation:

The total purchase can be described by ...

  4(2h +1.25) = 18.20 . . . . where h is the price of a hot dog

  8h = 13.20 . . . . . . . . . . . subtract 5.00

  h = 1.65 . . . . . divide by 8

The price of a hot dog was $1.65.
