A table titled Number of Dogs Adopted has entries 3, 3, 4, 4, 4, 5, 5, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9. The total is 13

Answer:

1) Mean = 6.28

2) Median = 7

3) Mode = 8

4) Range = 6

Step-by-step explanation:

We need to find Mean, Median, Mode and Range of data given in tables.

1) Mean

The formula used to calculate mean is: $Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}$

The data given is: 3, 3, 4, 4, 4, 5, 5, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9

Sum of all data points = 132

Number of data points = 21

Finding mean:

$Mean=\frac{Sum\:of\:all\:data\:points}{Number\:of\:data\:points}\\Mean=\frac{132}{21}\\Mean=6.28$

So, Mean = 6.28

2) Median

The formula used to calculate median is: $Median=\frac{n+1}{2}\:th\: term$ because we have n = odd

Number of data points n = 21

Putting values and finding the position of median term

$Median=\frac{n+1}{2}\:th\: term\\Median=\frac{21+1}{2}\:th\: term\\Median=\frac{22}{2}\:th\: term\\Median=11\:th\:term$

So, in the given data : 3, 3, 4, 4, 4, 5, 5, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9

The 11 th term is 7

So, Median = 7

3) Mode

The mode is the most repetitive value of data set.

In the given data set: 3, 3, 4, 4, 4, 5, 5, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9

The most repetitive value is 8

So, Mode = 8

4) Range

The range can be calculated using formula: $Range=Maximum\:Value-Minimum\:Value$

In the given data set: 3, 3, 4, 4, 4, 5, 5, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 8, 9, 9

Maximum value = 9

Minimum value = 3

So, the range is:

$Range=Maximum\:Value-Minimum\:Value\\Range=9-3\\Range =6$

So, Range = 6

A) Tonya bought 3 games at X price, so 3X would be total amount.

B) Tony's cost was 0.50 less than X, so x-0.50, he bought 4 games, so he spent 4(x-0.50).

C) Set those to equal to solve for x:

3x = 4(x-0.50)

D) Solve:

3x = 4(x-0.50)

Distribute:

3x = 4x - 2

Subtract 4x from both sides:

-X = -2

Multiply both sides by -1:

X = 2

E) Since X is the amount Tonya paid per game, Tony paid X - 0.50, so Tony paid 2 - 0.50 = $1.50 per game.

Check:

Tonya: 3x = 3(2) = $6 total

Tony: 4(x-0.50) = 4(2.00 - 0.50) = 4(1.50) = $6 total

Jasmine created this spinner to predict whether a randomly selected student in her school will be traveling during the upcoming

777dan777 [17]

Answer:

The number of students Jasmine surveyed indicated they would be traveling during the holiday break is 9.

Step-by-step explanation:

The spinner created by Jasmine, to predict whether a randomly selected student in her school will be traveling during the upcoming holiday break, has 8 equal sections labeled:

{yes, yes, no, no, no, no, no, no}

So, there are two sections labeled yes and six labelled as no.

Compute the probability of a yes as follows:

$P(\text{yes})=\frac{2}{8}=0.25$

Jasmine selected n = 36 students in her gym class.

If a student in her school will be traveling during the upcoming holiday break is independent of the other students.

Let the random variable X be defined as the number f students that will be traveling during the upcoming holiday break.

The random variable X follows a Binomial distribution with parameters n = 36 and p = 0.25.

Compute the expected value of X as follows:

$E(X)=np\\=36\times 0.25\\=9$

Thus, the number of students Jasmine surveyed indicated they would be traveling during the holiday break is 9.
