Answer:

Understand that statistics can be used to gain information about a population by examining a sample of the population; generalizations about a population from a sample are valid only if the sample is representative of that population. Understand that random sampling tends to produce representative samples and support valid inferences.

What is the median of 60 57 53 78 44 51 please help and thank u

maksim [4K]

To find the median cancel out numbers on both sides, until one is left in the middle and if there are two in the middle add them up and divide by two.

So in this case the median is
53+78
131 / 2
65.5

A traingle has vertices at A(-7, 6), B(4, 9), C(-2, -3). What are the coordinates of each vertex if the triangle is translated 4

Alenkinab [10]

Answer:

The coordinates of each vertex are

A'(-3, 0),B'(8,3) and C'(2,-9)

Step-by-step explanation:

we know that

The triangle is translated 4 units right and 6 units down

That means

The rule for the translation is equal to

(x,y) -------> (x+4,y-6)

Apply the rule of the translation to the coordinates of vertices ABC to obtain the vertices of the image A'B'C'

A(-7, 6) -----> A'(-7+4, 6-6)

A(-7, 6) -----> A'(-3, 0)

B(4, 9) ----> B'(4+4,9-6)

B(4, 9) ----> B'(8,3)

C(-2, -3) ----> C'(-2+4,-3-6)

C(-2, -3) ----> C'(2,-9)

Solve for X?<br> -6x+14<-28,9x+15<_-1

Gnom [1K]

｡☆✼★ ━━━━━━━━━━━━━━ ☾

-6x + 14 < -28

- 14 from both sides

-6x < -42

Divide both sides by -6

x > 7

9x + 15 < -1

- 15 from both sides

9x < -16

Divide both sides by 9

x < -16/9
