Answer: The required equation is y= 4x/3 - 3

Step-by-step explanation:

Given points (6,5) and (3,1)

Two point slope equation is  given as

y - y1 = \frac{y2-y1}{x2-x1}(x-x1)

where (x1, y1) and (x2,y2) are the points respectively

∴ y-5 =\frac{1-5}{3-6}(x-6)

y-5 =\frac{-4}{-3} (x- 6)

y -5 =\frac{4}{3} (x-6)

y - 5 =\frac{4}{3}x - 8

y = 5 +\frac{4}{3} x - 8

y = \frac{4}{3}x -3

It can also be written as

y -5 =\frac{4}{3}(x -6)

The 2-point form of the equation of a line can be written as ...

... y = (y2-y1)/(x2-x1)·(x -x1) +y1

For your points, this is ...

... y = (1-5)/(3-6)·(x -6) +5

... y = (4/3)(x -6) +5

It can also be written as

... y -5 = (4/3)(x -6)

Answer:

150 m^{2}

Step-by-step explanation:

Consider the figure as an isosceles triangle and a rectangle combined.

ISOSCELES TRIANGLE

A = \frac{1}{2} bh

A = \frac{1}{2} *15*12

A = 90

RECTANGLE

A=lw

A = 5*12

A = 60

60 + 90 = 150

ella [17]

Answer:

The standard deviation of the sampling distribution of x overbarx​, denoted sigma Subscript x overbarσx​, is called the​ standard error of the mean . The standard deviation of the sampling distribution of x overbarx​, denoted sigma Subscript x overbarσx​, is called the standard distribution of the sample.

Step-by-step explanation:

The standard error (SE) of a statistic is the standard deviation of its sampling distribution or an estimate of that standard deviation. It is called the standard error of the mean (SEM) if the parameter or the statistic is the mean.
