Gavin and his three friends want to share 1/3of cake equally. Gavin says that each friend will get 1/9 of the cake. Use the drop
Alexxandr [17]

Answer: Incorrect

Step-by-step explanation:

Given

Gavin and his three friends wants to share \frac{1}{3} of cake equally.

So, there are 4 members to distribute the cake

Each member will get

\Rightarrow \dfrac{\dfrac{1}{3}}{4}\\\\\Rightarrow \dfrac{1}{3\times 4}=\dfrac{1}{12}

So, each member get one-twelvefth of the given cake.

Hence, Gavin is  incorrect.

For a given event, what is the result of dividing the number of successful outcomes by the number of possible outcomes?
Zielflug [23.3K]
Dividing the number of successful outcomes by the number of possible outcomes is the definition of the probability of the given event.

P(E)=n(E)/n(S)

example. let the Experiment be throwing a dice. The sample space, all the possible outcomes, is the set S={1, 2, 3, 4, 5, 6 }  and n(S)=6

Let the even E be: getting an even number. The successful outcomes set is  E {2, 4, 6 } and n(E)=3

So probability of getting an even number is P(E)=n(E)/n(S)=3/6=0.5


Answer: Probability of the given Event

Height, in meters, is measured for each person in a sample. After the data are collected, all the height measurements
charle [14.2K]

Answer:

(E) The z-scores of the height measurements

Step-by-step explanation:

Mean is given by

\bar {x}=\frac{1}{n}\left(\sum _{i=1}^{n}{x_{i}}\right)=\frac{x_{1}+x_{2}+\cdots +x_{n}}{n}

Where,

n = Number of people

x_{i} = The heights of people

When converting m to cm the mean would be

\bar {x}=\frac{1}{n}\left(\sum _{i=1}^{n}{x_{i}}\right)\times 100

So, the mean would change

The median gives us the middle data value when the data values are in ascending order.

So, the median would change

Standard deviation

s=\sqrt{\frac{1}{N-1}\sum_{i=1}^{N}(x_i-\bar{x})^2}

When converting to centimeters

s=\sqrt{\frac{1}{N-1}\sum_{i=1}^{N}\left((x_i-\bar{x})\times 100\right)^2

Hence, the standard deviation would change

When converting to centimeters the maximum height in meters would be the maximum height in centimeters also.

The z score is given by

z=\frac{x-\mu}{\sigma}

where,

x = Data point

\mu = Mean

\sigma = Standard deviation

When converting to centimeters

z=\frac{(x-\mu)\times 100}{\sigma\times 100}\\\Rightarrow z=\frac{x-\mu}{\sigma}

Hence, the z score would remain the same
