Find the distance between points p (5, 1) and q (3,4)

DENIUS [597]

Answer:

D=3.60

Step-by-step explanation:

$D=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}$

Where

$(x_1,y_1) = (5,1)$

$(x_2,y_2) = (3,4)$

Replacing these values in the distance formula

$D =\sqrt{(5-3)^2+(1-4)^2}$

$D =\sqrt{(2)^2+(-3)^2}$

$D =\sqrt{4+9}$

$D =\sqrt{13}$

$D= 3.60$

Translate the point (15,32) using the rule (x,y) > (x +3, y - 7)

anzhelika [568]

Answer:

(18, 25 )

Step-by-step explanation:

The translation rule

(x, y ) → (x + 3, y - 7 )

means add 3 to the original x- coordinate and subtract 7 from the original y- coordinate, then

(15, 32 ) → (15 + 3, 32 - 7 ) → (18, 25 )

The mean of a sequence of n numbers is m. If we split the sequence into two sequences of lengths n1 and n2 and compute their mea

Furkat [3]

The mean of a sequence of numbers is the average.

The true statement is: $\mathbf{mn = m_1 \times n_1 + m_2 \times n_2}$

The given parameters are:

$\mathbf{Mean = m}$

$\mathbf{Size = n}$

The mean of a dataset is calculated as:

$\mathbf{Mean = \frac{\sum x}{Size}}$

So, we have:

$\mathbf{m = \frac{\sum x}{n}}$

Multiply both sides by m

$\mathbf{\sum x = mn}$

When the sequence is split into two, we have:

$\mathbf{\sum x_1 = m_1\times n_1}$

$\mathbf{\sum x_2 = m_2\times n_2}$

Where:

$\mathbf{\sum x_ = \sum x_1 + \sum x_2}$

So, we have:

$\mathbf{mn = m_1 \times n_1 + m_2 \times n_2}$

Hence, the true statement is: $\mathbf{mn = m_1 \times n_1 + m_2 \times n_2}$
