Im given a XY line, the midpoint is (3.-5) and the Y end is (0,2) how do I find the X ending of the line

romanna [79]

Using the midpoint formula, the coordinates of the endpoint X, are calculated as: X(6, -12).

<h3>How to Apply the Midpoint Formula?</h3>

The midpoint formula is expressed as: M(x, y) = [(x_1 + x_2)/2, (y_1 + y_2)/2].

We are given the following:

Line XY has a midpoint with the coordinates: (3, -5)

It has one endpoint: Y(0, 2)

To find the coordinates of the other endpoint, X, let:

X(?, ?) = (x_1, y_1)

Y(0, 2) = (x_2, y_2)

M (x, y) = (3, -5)

Plug in the values into the midpoint formula

M(3, -5) = [(x_1 + 0)/2, (y_1 + 2)/2]

Isolate and solve each variable

3 = (x_1 + 0)/2

6 = x_1

x_1 = 6

-5 = (y_1 + 2)/2

-10 = y_1 + 2

-10 - 2 = y_1

y_1 = -12

Therefore, the coordinates of the endpoint X, are: X(6, -12).

A set of data with a mean of 62 and a standard deviation of 5.7 is normally distributed. Find the value that is -1 standard devi

chubhunter [2.5K]

To answer this question, you must know what the standard deviation is.
The standard deviation is an index that measures the dispersion of a data set, while the largest is the standard deviation most dispersed are the data with respect to the mean value.
For a normal distribution, it is known that 68% of the data is not more than one standard desviation of the mean.
In this case, when they talk about -1 standard deviation of the mean.
Is:
average - 1 standard deviation
So
62 - 5.7 = 56.3
Therefore, the value sought is 56.3

a shopkeeper had 60 kg apples with him in the morning of a particular day during the day time he could sell only 43 kg 700 gram.

yan [13]

He has 16 kg 300 grams of apples left with him.

Explanation:
60 kg = 60 x 1000 = 60000 grams
43 kg 700 grams = 43700 grams

Left = 60000 - 43700 = 16300 grams = 16 kg 300 grams
