If M (4.2) is the midpoint of AB and A (-5, -3), find the coordinates of B.

loris [4]

Given:

M(4,2) is the midpoint of AB and A(-5, -3).

To find:

The coordinates of B.

Solution:

Let the coordinates of point B are (a,b).

Midpoint formula:

$Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

M(4,2) is the midpoint of AB and A(-5, -3).

$M=\left(\dfrac{-5+a}{2},\dfrac{-3+b}{2}\right)$

$(4,2)=\left(\dfrac{-5+a}{2},\dfrac{-3+b}{2}\right)$

On comparing both sides, we get

$4=\dfrac{-5+a}{2}$

$8=-5+a$

$8+5=a$

$13=a$

And,

$2=\dfrac{-3+b}{2}$

$4=-3+b$

$4+3=b$

$7=b$

Therefore, the coordinates of point B are (13,7).

Find the sample size required to achieve the given margin of error with SD = 51.02 and z - score = 1.96. Round your answer to th

coldgirl [10]

Answer:

The sample size required is 2500.

Step-by-step explanation:

z-score:

In function of the margin of error M, the z-score is given by:

$Z = \frac{M}{\frac{\sigma}{\sqrt{n}}} = \frac{M\sqrt{n}}{\sigma}$

In this question, we have that:

$\sigma = 51.02, M = 2, Z = 1.96$

$Z = \frac{M\sqrt{n}}{\sigma}$

$1.96 = \frac{2\sqrt{n}}{51.02}$

$2\sqrt{n} = 51.02*1.96$

$\sqrt{n} = \frac{51.02*1.96}{2}$

$(\sqrt{n})^2 = (\frac{51.02*1.96}{2})^2$

$n = 2500$

The sample size required is 2500.
