8 0

Answer:

15, 8, 13, 13

Step-by-step explanation:

(1) mean = Σx / n = 135 / 9 = 15

(2) range = highest value - lowest value = 21 - 13 = 8

(3) mode = 13 (most repeated value in data set)

(4) for 9 values in a data set, we have that (9 + 1) / 2 = 5th number

median = 13

Find the value of x......

ASHA 777 [7]

Answer:

100

Step-by-step explanation:

Since, line a is parallel to line t ( from diagram ).

x - 30 and 70 are alternate interior angles.

Reason : -

Alternate interior angles are equal when two lines are parallel and cut by a transversal line.

x - 30 = 70

x = 70 + 30

x = 100

In the circle below, O is the center and mĞ= 128° What is the measure of angle HIG?

Paul [167]

Answer:

26 degrees.

Step-by-step explanation:

From the figure it is clear that HI is the diameter and $acr(GI)=128^{\circ}$ . So,

$\angle GOI=128^{\circ}$

$\angle GOI+\angle GOH=180^{\circ}$ (linear pair)

$128^{\circ}+\angle GOH=180^{\circ}$

$\angle GOH=180^{\circ}-128^{\circ}$

$\angle GOH=52^{\circ}$

Using central angle theorem of a circle, we get

$\angle HIG=\dfrac{\angle GOH}{2}$

$\angle HIG=\dfrac{52^{\circ}}{2}$

$\angle HIG=26^{\circ}$

Therefore, the measure of angle HIG is 26 degrees.

What are the three coordinates that need to be plotted?

Maurinko [17]

Answer:

Step-by-step explanation:

y=2*|x-3|+2

y=|2*x-2*3|+2

y=|2x-6|+2

y=2x-6

x | 2 | 3 |

y | -2| 0 |

y=|2x-6|

y=|2x-6|+2

y=2*|x-3|+2.
