A coin is tossed 4 times. Find the probability of getting at 4 tails in a row.

Mathematics
1 answer:
7nadin3 [17]3 years ago
4 0

Answer:

6.25%

Step-by-step explanation:

Each time you flip a coin, there is a 50% probability of it landing on tails. Each time you flip the coin, the 50% gets multiplied by \frac{1}{2}.

\frac{1}{2} to the power of <em>4 </em>is 0.0625. 0.0625 in percentage form is of course 6.25%

The orgin of the coordinate plane is the point at (0,0). Why is the orgin an important point?
stiks02 [169]

<u>Importance of origin:</u>

The point at which the two axes intersect is called the origin. The intersecting x- and y-axes divide the coordinate plane into four sections.

The origin is at 0 on the x-axis and 0 on the y-axis. Since the origin has an x-coordinate of 0 and a y-coordinate of 0, its ordered pair is written (0, 0).

The origin is used to determine the coordinates for every other point on the graph. It is generally the starting point on a grid.

In general, origin is the place where something comes from or the place where something originates.

The diagram below models the layout at a carnival where G, R, P, C, B, and E are various locations on the grounds. GRPC is a par
Mila [183]

Answer:

Part A: Triangles GCB and PBE

Part B: They're similar because they have the same internal angles.

Part C:

250/400 = BE/450

112500/400 = BE

BE = 281.25 ft

250/400 = PE/350

87500/400 = PE

PE = 218.75 ft

Heston wagons reported in June that 20 out of 500 wagons failed inspection. In July they reported that 25 out of 625 wagons fail
elena-14-01-66 [18.8K]

Answer:

The proportion is \frac{y}{x} =\frac{1}{25}

Step-by-step explanation:

We have to:

In June 20 of 500 wagons failed

On July 25 of 625 wagons failed

If we call x the number of wagons and and the number of wagons that had failures then we have to for June:

\frac{y}{x} = \frac{20}{500}\\\\\frac{y}{x} = \frac{1}{25}

For July we have

\frac{y}{x} = \frac{25}{625}\\\\\frac{y}{x} = \frac{1}{25}

The proportions are the same for both months

\frac{20}{500} = \frac{25}{625}

The proportion is \frac{y}{x} =\frac{1}{25}

This means that of every 25 wagons, one has faults
