Answer:

The mean increases by 1.7°

Step-by-step explanation:

1) Find the mean of the numbers given first

Mean = sum of number ÷ number of numbers

Sum of numbers = 58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 = 965

Number of numbers = 12

2) Find the mean of numbers including the additional 103

Sum of numbers = 58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 103 = 1068

Number of numbers = 13

3) Find the difference

If we use the results rounded to one decimal place we will be left with 80.4 and 82.2

Answer:

10x+40

Step-by-step explanation:

Answer:

10 (x + 4) = 10x +40, I'm pretty sure that's the answer. Try that out :)

Step-by-step explanation:

I did distributed this equation, I did 10 times X, which x mean 1 and you would do 10 times 1, which is 10, but adding the variable in there so the variable would be X. And then I did the same thing except you do 10 times 4 and notice that there was a plus sign and not a minus sign. If there would be a minus sign it would be a negative answer, but with a plus sign it would be a positive answer, which is 40! :)

Hope that helps and hope that kinds make sense! :)

ANSWER: 10x + 40

Reason:

6 black out of 4+6+5 = 15 total

6/15 = 0.40 is the experimental probability of selecting black.

Side note: The term "empirical probability" is the same as "experimental probability".

The experimental probability of selecting a black marble will be 0.40. The correct option is C.

Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favourable outcomes to all outcomes.

Probability = Number of favourable outcomes / Number of samples

Given that Michael has a bag of marbles. The frequency of selecting each colour is recorded in the table below. Outcome Frequency Green 4 Black 6 Orange 5.

Number of favourable outcomes = 6

Number of samples = 4+6+5 = 15

Probability = Number of favourable outcomes / Number of samples

Probability = 6 / 15

Probability = 0.40

Therefore, the probability will be 0.40.

Answer:

\(9.05 * 10^{7} kg\)

Step-by-step explanation:

Given

\(Statue\ of\ Liberty\ =\ 2.04 * 10^5 kg\)

\(Washington\ Monument\ =\ 9.07 * 10^7 kg\)

To get the number of kilograms the Washington Monument weighs more than the Statue of Liberty, we simply calculate the difference;

Difference = Washington Monument - Statue of Liberty

\(Difference = \ 9.07 * 10^7 kg - \ 2.04 * 10^5 kg\)

Expand \(10^7\)

\(Difference = \ 9.07 * 10^{5+2} kg - \ 2.04 * 10^5 kg\)

\(Difference = \ 9.07 * 10^{5} * 10^2 kg - \ 2.04 * 10^5 kg\)

Take out the common factor in the above expression

\(Difference = 10^{5}\ (\ 9.07 * 10^2 kg - \ 2.04\ kg)\)

\(10^2 = 100;\) so we have

\(Difference = 10^{5}\ (\ 9.07 * 100 kg - \ 2.04\ kg)\)

\(Difference = 10^{5}\ (\ 907 kg - \ 2.04\ kg)\)

\(Difference = 10^{5}\ (904.96\ kg)\)

Open bracket

\(Difference =904.96 * 10^{5} kg\)

Write in standard form

\(Difference =9.0496 * 10^2 * 10^{5} kg\)

\(Difference =9.0496 * 10^7 kg\)

\(Difference =9.05 * 10^7 kg\) (Approximated)

Hence, he Washington Monument weigh more than the Statue of Liberty by about \(9.05 * 10^{7} kg\)

11/24 = between 0 and 1/2

14/15 = between 1/2 and 1

Step-by-step explanation:

Well, you can see that for 3 5/8, 3 is clearly greater than 1.

For 11/24, you know that 12 is half of 24, so 11/24 is between 0 and 1/2.

For 14/15, it is closest to 1, so it is between 1/2 and 1

Answer:

A. The students tend to have fewer siblings than the teachers.

Step-by-step explanation:

First we need to draw the dot plots correctly. If you count both sides they have 20 each.

Now, clearly none have fewer nobody here yet has more or less but going on to the next step.

Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14.  And so on.

On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.

So the answer is A. The students tend to have fewer siblings than the teachers.

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Answer: 22.5 pounds

Step-by-step explanation:

The computation of the weight of the block of gel is shown below:

As we know that

Volume = (length) (width) (height)

= (20) (6 ) (6)

= 720 cubic inches 

Now we have to convert into cubic foot

As we know that

1 ft = 12 inches

So 1ft^3 = 12 inches^3

= 1728 inches ^3
Now

= 720 × 1 cubic foot ÷ 1728 cubic inches

= 5 ÷ 12

Now the weight is = 54 × 5 ÷ 12= 

22.5 pounds

Both the interquartile range (IQR) and the range indicate that Bus 18 is the more consistent option. Its IQR of 16 and range of 16 are both smaller than the corresponding values for Bus 47, implying that the travel times of the students on Bus 18 are more consistent and have less variability.

To determine which bus is the most consistent, we can compare the measures of variability provided for each bus, namely the interquartile range (IQR) and the range.

The IQR is a measure of spread that represents the range of the middle 50% of the data. It is calculated by subtracting the first quartile (Q1) from the third quartile (Q3) of a dataset. The IQR provides information about the spread of the central portion of the data, ignoring outliers.

Looking at the given information:

For Bus 18:

IQR = 16

For Bus 47:

IQR = 24

Comparing the IQRs, we can conclude that Bus 47 has a larger IQR of 24, while Bus 18 has a smaller IQR of 16. A larger IQR indicates a greater spread or variability in the data, suggesting that the travel times of the students on Bus 47 vary more widely than those on Bus 18. Therefore, Bus 18 is more consistent or has less variability in travel times based on the IQR.

Additionally, we can also consider the range, which is the difference between the maximum and minimum values in a dataset. The range provides a measure of the total spread of the data, including the extreme values.

For Bus 18:

Range = 16

For Bus 47:

Range = 24

Comparing the ranges, we see that Bus 47 has a larger range of 24, while Bus 18 has a smaller range of 16. Similar to the IQR, a larger range indicates a wider spread or variability in the data, whereas a smaller range suggests less variability. Therefore, based on the range as well, Bus 18 is more consistent or has less variability in travel times compared to Bus 47.

In summary, both the interquartile range (IQR) and the range indicate that Bus 18 is the more consistent option. Its IQR of 16 and range of 16 are both smaller than the corresponding values for Bus 47, implying that the travel times of the students on Bus 18 are more consistent and have less variability.

Step-by-step explanation:

The Allstars team has the higher mean and median compared to Champs team. Therefore, the Allstars has the tallest players.

By using mean and median, we can know which team typically has the tallest players

For the Allstars:

Mean: The mean height of the Allstars team is obtained by summing up all the heights and dividing by the total number of players:

Mean = (73 + 62 + 60 + 63 + 72 + 65 + 69 + 68 + 71 + 66 + 70 + 67 + 60 + 70 + 71) / 15 ≈ 67.1 inches

Median: The median height of the Allstars team is the middle value when the heights are arranged in ascending order:

Arranging the heights in ascending order: 60, 60, 62, 63, 65, 66, 67, 68, 69, 70, 70, 71, 71, 72, 73

Median = 68 inches

For the Champs:

Mean: The mean height of the Champs team is obtained by summing up all the heights and dividing by the total number of players:

Mean = (62 + 69 + 65 + 68 + 60 + 70 + 70 + 58 + 67 + 66 + 75 + 70 + 69 + 67 + 60) / 15 ≈ 66.4 inches

Median: The median height of the Champs team is the middle value when the heights are arranged in ascending order:

Arranging the heights in ascending order: 58, 60, 60, 62, 65, 66, 67, 67, 68, 69, 69, 70, 70, 70, 75

Median = 67 inches

The Allstars team typically has the tallest players. The mean height of the Allstars team is about 67.1 inches, while the mean height of the Champs team is about 66.4 inches. Additionally, the median height of the Allstars team is about 68 inches, while the median height of the Champs team is about 67 inches. Both the mean and median heights of the Allstars team are higher, indicating that, on average, the Allstars team has taller players compared to the Champs team.
