Answer:

32768 ways

Step-by-step explanation:

Given

Marbles = 8 marbles

Selection = 5 (with replacement)

Required

Determine the number of ways

Because it is a selection with replacement; each selection is as follows:

First = 8\ marbles

Second = 8\ marbles

Third= 8\ marbles

Fourth = 8\ marbles

Fifth = 8\ marbles

Total number of ways is then calculated as:

Total = 8 * 8 * 8 * 8 * 8

Total = 32768

The coordinates of point B are (-4 , -2) ⇒ answer H

Step-by-step explanation:

In any circle

  • The diameter of the circle passing through its center
  • The center of the circle is the mid-point of all diameters

If (x , y) are the coordinates of the mid-point of a line whose end

points are (x_{1},y_{1}) and (x_{2},y_{2}) , then

x=\frac{x_{1}+x_{2}}{2} and y=\frac{y_{1}+y_{2}}{2}

∵ Point C is the center of a circle

∵ AB is the diameter of the circle

∴ C is the mid point of AB

∵ A = (2 , 6) ⇒ (x_{1},y_{1})

∵ B = (x_{2},y_{2})

∵ C = (-1 , 2) ⇒ (x , y)

- Use the rule of the mid-point above

∵ -1=\frac{2+x_{2}}{2}

- Multiply both sides by 2

∴ -2 = 2 + x_{2}

- Subtract 2 from both sides

∴ x_{2} = -4

∴ The x-coordinate of point B is -4

∵ 2=\frac{6+y_{2}}{2}

- Multiply both sides by 2

∴ 4 = 6 + y_{2}

- Subtract 6 from both sides

∴ y_{2} = -2

∴ The y-coordinate of point B is -2

The coordinates of point B are (-4 , -2)

Mrs. Simpson drove 105 miles in 2 1/2 hours. What was Mrs. Simpson's average speed in miles per hour?
harkovskaia [24]
105 m = 2.5 h
 
x miles = 1 hour

You cross multiply since it's a proportion:
2.5 * x
105 * 1

=

2.5x = 105

Then you divide everything by 2.5

The answer is 42
