Relationship between mean median and mode

Mathematics

Answer:

It looks like the median is higher than both the mode and mean. The mean is not higher than the median but more than twice as much as the mode. The mode is lower than the median and mode.

The mode is the most of a reoccurring number- so in your case 14 was the mode as stated. It appeared the most times.

The median in putting every single number in numerical order from least to greatest and crossing them off until you reach the exact center. If you have two numbers left, take the average of the two.

The mean is adding up all the numbers and dividing by how many there are to find the average. It looks like the mean is fairly close to the median so all the numbers were probably close together in bunches.

A school has a hurdle track that is 1/5 of a mile long. They are considering extending the track to be 1/4 of a mile long. The c

Anastaziya [24]

Answer: 4/5

Step-by-step explanation:

Here, The hurdle track that is 1/5 of a mile long.

And, After extending the track, the length of the hurdle track = 1/4 of a mile

Therefore, the unit rate of length in the longer track per mile of length in the shorter track = the initial length of the hurdle track / the final length of the hurdel track

= $\frac{1/5}{1/4}$

= $\frac{4}{5}$

An observer standing on a cliff 320 feet above the ocean measured angles of depression of the near and far sides of an island to

Gnesinka [82]

Answer:

154.10 Feets

Step-by-step explanation:

Given the following :

Height (h) of cliff = 320 feet

Angle of depression of near side = 16.5°

Angle of depression of far side = 10.5°

Using trigonometry :

We can obtain x and y as shown in the attached picture :

Tanθ = opposite / Adjacent

Adjacent = height of cliff = 320 Feets

For the near side :

Tanθ = opposite / Adjacent

Tan (16.5°) = x / 320

0.2962134 = x / 320

x = 0.2962134 * 320

x = 94.788318 Feets

For the far side :

Tanθ = opposite / Adjacent

Tan (10.5°) = x / 320

0.1853390 = x / 320

x = 0.1853390 * 320

x = 59.308494 Feets

Length of island = (59.308494 + 94.788318) feet

= 154.10 Feets

On story Ratios Worksheet 3: how do you do this problem. Jackie sold lemonade and made $24 while Liana sold lemonade and made $3

Drupady [299]

Answer:

Ratios of money made by Jackie and Liana = $\frac{2}{3}$

Step-by-step explanation:

We have given,

On selling a lemonade :

Money made by Jackie = $24

Money made by Liana = $36

We need to find the ratios of money made by Jackie and Liana by selling lemonade.

So, Ratio = Money made by Jackie / Money made by Liana

or , Ratio = $\frac{24}{36}$

or, Ratio = $\frac{2}{3}$

So, the ratios of money made by Jackie and Liana is $\frac{2}{3}$

By visual inspection, determine the best-fitting regression<br> model for the data plot below.

Firlakuza [10]

Answer:

A. linear

Step-by-step explanation:

A linear model is the best-fitting regression model for the data plot because for similar variations in x values, the variation in y values are also similar, that is, if you take points (x1, y1), (x2, y2) and (x3, y3) the y1 - y2 is similar to y2 - y3, when x2 - x1 is also similar to x3 - x2.

PLEASE HELP FAST!!!!

Dmitry [639]

Answer:

Mark has the correct answer. Ryan and Jessica both made mistakes in their calculations with computing negative integers.

Step-by-step explanation:

Looking at the graphing method first, we need to get both equations into the slope-intercept format (y = mx + b) to compare these variables:

y = 3x + 2 has a slope = 3 and y-intercept = 2

6x - 2y = 10 can also be written as -2y = -6x + 10 or y = 3x - 5 which also has a slope = 3, but a y-intercept = -5

Since both lines have the same slope, then we know they must be parallel and therefor, there is no solution.

Ryan used elimination to solve his system, however, when converting both equations to standard form (Ax + By = C), he forgot to make the '3x' from the first equation negative, or '-3x', which made the rest of his calculations incorrect.

Jessica used matrices and made the determinant for the system, x and y. Jessica set up her determinant correctly, however, when solving the system determinant, she did not multiply 3 x -2 correctly and instead put positive 6 instead of -6 which made her answer 12 instead of 0.
