Answer:

Sierra's team has a greater percent of left-handed batters.

25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.

Step-by-step explanation:

Sierra: 7/28 = 1/4

1/4 written as a percentage is 25%

Aubrey: 5/25 = 1/5

1/5 written as a percentage is 20%

25% is greater than 20%, so Sierra's team has a greater percent of left-handed batters.

25% of Sierra's team bat left handed and 20% of Aubrey's team bat left handed.

Hope this helps ;)

<h3>Question A: </h3>

Which team has a greater percent of left-handed batters?

<h3>Solution:</h3>

Sierra's team has a greater percentage of left-handed batsmen than Aubrey. Below is the work.

<u>Aubrey's team: 5/25 left-handed batsmen</u>

=> 5/25 x 100 = 1/5 x 100
=> 20%

<u>Sierra's team: 7/28 left-handed batsmen</u>

=> 7/28 x 100
=> 1/4 x 100
=> 25%

<u>Hence, Sierra's team has a greater percentage of left-handed batsmen than Aubrey. </u>

<h3>Question B: </h3>

What percent of the players on Sierra's team bat left-handed?

<h3>Solution:</h3>

<u>25% of the players on Sierra's team are left-handed batsmen.</u>

Below is the work.

Sierra's team: 7/28 left-handed batsmen
=> 7/28 x 100
=> 1/4 x 100
=> 25%

<u>Hence, 25% of the players on Sierra's team are left-handed batsmen.</u>

Maslowich

Answer:

Part A:

$2^{40}-2\\=1.0995*10^{12} ancestors$

Part B:

Generations Age=25*39=975 years

Part C:

Some ancestors on different branches of the family tree must be the same.
There could not have been 39 generations in my line of ancestry.

Step-by-step explanation:

Given Data:

Two Parents, Four Grand Parents, Eight great Grand Parents.

Generation=39

Solution:

Part A:

From given data Following series is made:

$2+2^2+2^3+.........+2^{39}$

Now, Above series will become:

$2[1+2+2^2+......+2^{38}]$

From geometric Sequence:

$2[\frac{2^{38+1}-1}{2-1} ]$

$2^{40}-2\\=1.0995*10^{12} ancestors$

Part B:

Generations Age=years*Number of generations

Generations Age=25*39=975 years

Part C:

Number of people lived= 10^11

Ancestors= $1.0995*10^{12} ancestors$

$10^{11}$

It means ancestors are not distinct, it means:

Some ancestors on different branches of the family tree must be the same.
There could not have been 39 generations in my line of ancestry.

I NEED HELP WITH THIS! ANYONE???

Aneli [31]

Answer:

y-axis, x-axis, y-axis, x-axis

Step-by-step explanation:

Alright, so this problem looks a lot harder than it really is. When you flip a point across the x axis, y becomes negative, and when it is flipped across the y axis, x becomes negative. This means that if the x value changes signs it was flipped on the y axis, and vice versa.

On Friday night, the owner of Chez Pierre in downtown Chicago noted the amount spent for dinner for 28 four-person tables. 95 10

Shalnov [3]

Answer:

(a) The mean is 107.25, median is 106 and mode is 95.

(b) The data set is right-skewed.

Step-by-step explanation:

The sample space of amount spent for dinner for 28 four-person tables is:

S = {95, 103, 109, 170, 114, 113, 107, 124, 105, 80, 104, 84, 176, 115, 69, 95, 134, 108, 61, 160, 128, 68, 95, 61, 150, 52, 87, 136}

There are <em>n</em> = 28 values in the set.

(a)

The mean of this data set is:

$\bar x=\frac{1}{n} \sum x=\frac{1}{28} \times3003=107.25$

The mean is 107.25.

The data set consists of even number of observations.

The median for an even set of data is the mean of the middle two numbers.

First arrange the data set in ascending order:

52, 61 , 61 , 68 , 69 , 80 , 84 , 87 , 95 , 95 , 95 , 103 , 104 , 105 , 107 , 108 , 109 , 113 , 114 , 115 , 124 , 128 , 134 , 136 , 150 , 160 , 170 , 176

The median is the average value of the 14th and 15th observation.

$Median=\frac{14^{th}obs.+15^{th}obs.}{2}=\frac{105+107}{2}=106$

The median is 106.

The mode of a data set is the value with the most frequency.

Consider the arranged data set.

52, 61 , 61 , 68 , 69 , 80 , 84 , 87 , 95 , 95 , 95 , 103 , 104 , 105 , 107 , 108 , 109 , 113 , 114 , 115 , 124 , 128 , 134 , 136 , 150 , 160 , 170 , 176

The value 95 is repeated most of the times.

Thus, the mode is 95.

(b)

The value of mean, median and mode are related as follows:

Mean > Median > Mode

This implies that the data is skewed.

In case of a right-skewed data the Mean > Median > Mode.

In case of left skewed data the Mean < Median < Mode.

Thus, the data set is right-skewed.
