Which description best fits the distribution of the data shown in the histogram?
Sedaia [141]

Option B: Approximately bell-shaped

Explanation:

Option A: Skewed

A histogram is said to be skewed if most of the larger values falls either on the left or right side.

Clearly, the given histogram is not skewed.

Thus, Option A is not the correct answer.

Option B: Approximately bell-shaped

A graph is said to be bell shaped if a vertical line is drawn at the center which will form a mirror image of the left half of the graph with the right half.

Clearly, the given histogram is approximately bell-shaped.

Thus, Option B is the correct answer.

Option C: Uniform

A graph is said to be uniform if its data is equally spread across the range.

Clearly, the given histogram is not Uniform.

Thus, Option C is not the correct answer.

Option D: Skewed left

A graph is said to be skewed left if the smaller values fall on the left side of the graph.

Clearly, the given histogram is not skewed left.

Thus, Option D is not the correct answer.

Hence, Option B is the correct answer.

A spherical ball has a diameter of 8 inches. The ball has a slow leak in which the air escapes at the rate of 2.5 inches per sec
s344n2d4d5 [400]

Answer:

107.2 seconds

Step-by-step explanation:

Step one:

given

the diameter of ball 8 inches

radius= 8/2 = 4 in

The volume of the ball

v=4/3 \pi r^3

v= 4/3*3.142*4^3\\\\v= 4/3*3.142*64\\\\v= 804.35/3\\\\v=268.12 in^3

Step two:

we know that

rate= quantity/time

rate= 2.4 in per second

quantity= 268.12

time=?

time= quantity/rate

time= 268.12/2.5

time= 107.2 seconds
