Answer:

p = 0.35

q = 0.65

n = 7

Step-by-step explanation:

To calculate the distribution, we have the following values;

p = 35% = 35/100 = 0.35

q = 1-p = 1-0.35 = 0.65

n = 7

What is the slope of the table.
aev [14]

Answer:

slope is -5

Step-by-step explanation:

The formula for slope is:

m = (y2 - y1)/(x2 - x1)

m = slope

y2 = y-coordinate of second point

y1 = y-coordinate of first point

x2 = x-coordinate of second point

x1 = x-coordinate of first point

We can choose our first and second points as any points on the table, but we will choose the first andd second points which are (-5,10) and (-3,0).

y2 = 0

y1 = 10

x2 = -3

x1 = -5

m = (0-10)/(-3-(-5))

m = (-10)/(-3+5)

m = (-10)/(2)

m = -5

A rectangular container has a base that is 12 inches long and 8 inches wide. The container is filled with water to a height of 6
valina [46]

Answer: the length of one edge of the square base of the second container is 6 inches.

Step-by-step explanation:

The formula for determining the volume of a rectangular container is expressed as

Volume = length × width × height

Considering the first container,

Length = 12 inches

Width = 8 inches

Height to which the water is filled is 6 inches.

Therefore, volume of water in the container is

12 × 8 × 6 = 576 inches³

Considering the second container,

Height of water = 16 inches

Let L represent the length of the square base. Then the area of the square base is L²

Volume of water would be 16L²

Since the water in the first container was poured into the second container, then

16L² = 576

L² = 576/16 = 36

L = √36

L = 6 inches
