Answer:

37.2

Step-by-step explanation:

when you turn the small triangle LMN to its right angle to cover the right angle of KLM, you find that they are similar triangles.

therefore the corresponding side lengths are at the same ratio.

LM/KM = MN/LN

LM = 24

MN = 13

we can get LN via Pythagoras of the small triangle

LN² + MN² = LM²

LN² + 13² = 24²

LN² = 24² - 13² = 576 - 169 = 407

LN = sqrt(407) = 20.174241

now back to our main problem

24/KM = 13/sqrt(407)

24×sqrt(407)/13 = KM = 37.2

The measure that always represents the 50th percentile is the median. It is the middle value when data is sorted and is robust to outliers, unlike the mean.

The measure that always represents the 50th percentile in a dataset is the median. The median is the middle value in a dataset when it is ordered from smallest to largest. It divides the data into two equal halves, with half of the values falling below it and half above it.

Unlike the mean, which is the average of all values and can be influenced by extreme outliers, the median is robust to outliers because it solely depends on the middle value. This makes it a better measure of central tendency when dealing with skewed or non-normally distributed data.

On the other hand, the upper quartile, also known as the third quartile, represents the 75th percentile. It divides the data into the upper 25% and lower 75%. The mean is the average of all values in the dataset and does not necessarily correspond to any specific percentile.

In summary, the median always corresponds to the 50th percentile and is a valuable measure for understanding the central tendency of a dataset, especially when dealing with skewed data or outliers, while the mean and upper quartile represent different points in the data distribution.

Answer:

1   1/4

Step-by-step explanation:

You don't add the bottom one you have to dived it by two and it is a decmail one so you have to add it it and you want to keep the bottom and it is fifteen sone you want to add the one as the whole number and keep the one for the top and keep the bottom one so you will get 1 1/4 and I use this one and it was right!

Answer:

according to the problem the payment Sal did correspond to

(2 rent + 1200)/3 = 1000

2 rent + 1200 = 3000

2 rent = 1800

rent = 900

this means that

rent = $900
