Using the median concept, it is found that the third quartile is of is of $1,052.

<h3>What is the median of a data-set?</h3>

The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.

In this problem, the ordered data-set is:

$379, $498, $619, $777, $895, $1,052, $1,256.

Hence, the median of $777 divides the data-set into two halfs:

  • The first half is: $379, $498, $619.
  • The second half is: $895, $1,052, $1,256.

Hence, the third quartile, which is the median of the second half, is of $1,052.

How can I determine the line of best fit, and how will this help me to make predictions?
HACTEHA [7]

Answer:

A line of best fit can be roughly determined using an eyeball method by drawing a straight line on a scatter plot so that the number of points above the line and below the line is about equal (and the line passes through as many points as possible).

A. Encuentra el valor del tercer ángulo en un triángulo que tiene dos ángulos que miden 112º Y 52º B. Encuentra el valor del cua
IgorLugansk [536]

Answer:

El tercer ángulo en un triángulo será 16 ° si los otros dos ángulos son 112º y 52º.

El cuarto ángulo en un cuadrilátero será 213 ° si los otros tres ángulos son 105º, 32º y 10º.

Step-by-step explanation:

<u><em>Spanish</em></u>

La suma de los ángulos de un triángulo siempre es igual a 180 grados. Si conocemos dos de ellos, podemos encontrar el tercero. Dejemos que el tercero se denote por x entonces

112 ° + 52 ° + x = 180 °

x = 180 ° -112 ° -52 °

x = 16 °

El tercer ángulo en un triángulo será 16 ° si los otros dos ángulos son 112º y 52º.

La suma de los ángulos de un cuadrilátero siempre es igual a 360 grados. Si conocemos tres de ellos, podemos encontrar el cuarto. Dejemos que el cuarto se denote por y luego

105º + 32º + 10º + y = 360 °

o

y = 360 ° -105º- 32º- 10º

y = 213 °

El cuarto ángulo en un cuadrilátero será 213 ° si los otros tres ángulos son 105º, 32º y 10º.

<u><em>English</em></u>

The sum of angles in a triangle is always equal to 180 degrees. If we know any two of them we can find the third one. Let the third one be denoted by x then

112°+52°+x= 180°

x=  180°-112°-52°

x= 16°

The third angle in a triangle will be 16° if the other two angles are 112º and 52º.

The sum of angles in a quadrilateral is always equal to 360 degrees. If we know any three of them we can find the fourth one. Let the fourth one be denoted by y then

105º+ 32º+  10º+y= 360°

or

y = 360°-105º- 32º- 10º

y= 213°

The fourth angle in a quadrilateral  will be 213° if the other three angles are 105º, 32º and 10º.

Which expression has the greatest value |-21|, |14|, |30|, |-45|
tresset_1 [31]

Answer:

|-45|

Step-by-step explanation:

In mathematics, the absolute value of a real number is the numeric value of the  number, regardless the sign, either this is positive or negative.

The absolute value function can be definied as:

  • |a|=a si a ≥0
  • |a|=-a si a <0

Using this definition, we have:

|-21| = -(-21) = 21

|14| = 14

|30| = 30

|-45| = -(-45) = 45

Therefore, the expression |-45| has the greatest value.

The question: a computer manufacturer built a new facility for assembling computers. there were construction and new equipment c
DiKsa [7]

Answer:

The equation that closely represents the graph is \mathbf{y=60x-160}

Option A is correct.

Step-by-step explanation:

We need to find equation that represents the graph.

We can write equation in slope-intercept form: y=mx+b where m is slope and b is y-intercept.

For finding the equation we need to find slope and y-intercept

Finding slope

The slope can be found using formula: Slope=\frac{y_2-y_1}{x_2-x_1}

From the graph we can find x_1=0, y_1=-160, x_2=1, y_2=-100

Putting values and finding slope

Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{-100-(-160)}{1-0} \\Slope=\frac{-100+160}{1}\\Slope=-100+160\\Slope=60

We get Slope = 60

Finding y-intercept

Using point (0,-160) and slope m = 60, we can find y-intercept

y=mx+b\\-160=60(0)+b\\b+0=-160\\b=-160

Writing the equation

So, the equation for given graph having slope m = 60 and y-intercept b =-160 is:

y=mx+b\\y=60(x)+(-160)\\y=60x-160

So, The equation that closely represents the graph is \mathbf{y=60x-160}

Option A is correct.
