Answer:

19.

Step-by-step explanation:

First arrange in ascending order:

16, 16, 18, 19, 21, 25, 27, 30, 34, 49, 50, 58, 59, 71, 75.

There are a total of 15 numbers, so the median is the 8th number = 30.

The lower quartile is halfway alone the first 7 numbers which is the 4th number and it is 19.

The median which is the middle number

Answer:

Reason : by ASA , x = 36

Step-by-step explanation:

∠ABC = ∠EBD (vertically opposite angle)

BC = BD = 54 (same length)

∠BAC = ∠BDE (alternate interior angles)

By ASA , ΔABC ≅ ΔDBE

$54 \times x = 36 \times 54\\\\x = 36$

What is the result of a dilation of scale factor 3 centered at the origin of the line 2y + 3x=10

romanna [79]

Answer:

(10, 15)

Step-by-step explanation:

To get the origin of the equation 2y+3x = 10, we need to get the x and y-intercept of the line.

x-intercept occurs at y = 0

If y = 0

2(0)+3x =10

3x =10

x = 10/3

x = 1.33

y-intercept occurs at x = 0

If x = 0

2y+3(0) =10

2y =10

y = 10/2

y = 5

Hence the coordinate at the origin is (10/3, 5). If this coordinate is dilated by 3, the required coordinate will be at (10/3*3, 5*3) = (10, 15)

Hence the required coordinate is (10, 15)
