What is the difference in finding the length of a segment that is drawn on a sheet of blank paper and segment that is drawn on a

coordinate plane?

If you have tickmarks on the segment, on a blank piece of paper, then you count out the spaces to get the length of the segment. This is assuming the tickmarks are properly spaced out. If there aren't any tickmarks, then you'll have to use a ruler to find the length. Either way, a ruler is encouraged.

The coordinate plane makes things easier to find the length of any segment. Use either the pythagorean theorem or the distance formula to find the length of the segment.

You tell your 3 friends that you are going to a magic show. It turns out, in an amazing coincidence, they each
Inga [223]

Answer:

\frac{1}{4845} probability that you and your 3 friends will be selected.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the order in which the volunteers are chosen is not important, which means that the combinations formula is used to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

Desired outcomes:

You and the 3 friends(4 people), from a set of 4. So

D = C_{4,4} = \frac{4!}{4!0!} = 1

Total outcomes:

20 people from a set of 20. So

T = C_{20,4} = \frac{20!}{4!16!} = 4845

Probability:

p = \frac{D}{T} = \frac{1}{4845}

\frac{1}{4845} probability that you and your 3 friends will be selected.

Find the diameter of a cone that has a volume of 104.67 cubic inches and a height of 4 inches. Use 3.14 for pi.
Lady bird [3.3K]

Answer:

Step-by-step explanation:

The volume of a cone is

V=\frac{1}{3}\pi r^2h

Filling in what we have:

104.67=\frac{1}{3}(3.14)r^2(4)  and simplifying a bit:

104.67=\frac{1}{3}(12.56)r^2

Multiply both sides by 3 to get:

314.01=12.56r^2

Divide both sides by 12.56 to get:

25.00079618=r^2 and take the square root of both sides to find the radius:

r = 5

If the radius is 5 and the radius by definition is half the diameter, then the diameter is 10 inches.
