3.5 m

marysya [2.9K]

Answer:

This question seems to be incomplete, I guess that we have a circular pool, with a diameter of 3.5 m.

Now, the circunference of a circle can be written as:

C = 2*pi*r

where:

pi = 3.14

r = radius = half of the diameter = 3.5m/2 = 1.75m

Then replacing those values in the equation for the circumference we have:

C = 2*3.14*1.75m = 10.99 m.

And knowing that the value of pi is actually larger than 3.14 (pi = 3.1415926535....)

We can safely round up the circumference to the next whole number, C = 11m

A rack of 15 billiard balls is shown. If one ball is selected at random, determine the odds against it containing a number grea

andre [41]

Using the probability and odds concepts, it is found that the odds against it containing a number greater than or equal to 7 is $\frac{2}{3}$ .

A probability is the number of desired outcomes divided by the number of total outcomes.
An odd is the number of desired outcomes divided by the number of non-desired outcomes.

In the rack, there are 15 balls, numbered from 1 to 15. Of those, 6 are less than 7(against it containing a number greater than or equal to 7 is equivalent to it containing a number less than 7), thus:

There are 6 desired outcomes.
There are 9 non-desired outcomes.

The odd is:

$\frac{6}{9} = \frac{2}{3}$

The odds against it containing a number greater than or equal to 7 is $\frac{2}{3}$ .

Answer:

Step-by-step explanation:

Least common denominator is 10

there are 10/10 portions in the whole circle

1/2 = 5/10

2/5 = 4/10

10/10 - 5/10 - 4/10 = 1/10
