What is the value of the x-coordinate of point A?

Mathematics

Answer:

X Coordinate. The horizontal value in a pair of coordinates: how far along the point is. The X Coordinate is always written first in an ordered pair of coordinates (x,y), such as (12,5). In this example, the value "12" is the X Coordinate.

The coordinates of point A will be (0, 0) and the coordinates of B will be (3, 2).

To find these coordinates you have to graph the points and line segments. You will see that the 2 line segments start at points C and D and move down to the right. The endpoints of these segments will form your parallelogram.

Consider the following hypothesis test: H 0: 20 H a: < 20 A sample of 50 provided a sample mean of 19.4. The population stand
goblinko [34]

Answer: p-value is 0.016.

Step-by-step explanation:

Since we have given that

H_0:\mu=20\\\\H_a:\mu

Sample mean = 19.4

Sample size n = 50

Standard deviation = 2

We need to find the test statistic value which is given by

z=\dfrac{\bar{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\\\z=\dfrac{19.4-20}{\dfrac{2}{\sqrt{50}}}\\\\\\z=\dfrac{-0.6}{0.28}\\\\z=-2.14

p-value is given by

P(Z>Z_{critical})\\\\=P(Z>-2.14)\\\\=0.016

Hence, p-value is 0.016.

Dennis_Churaev [7]

Answer:

the balance is 2075 dollars

Step-by-step explanation:

The answer is 2075 because 1.25% of 2000 is 25 and 25 multiplied by 3 is 75 and 75 plus 2000 is 2075.

Point \blue{A}Astart color blue, A, end color blue is at \blue{(-4, 8)}(−4,8)start color blue, left parenthesis, minus, 4, comma
ASHA 777 [7]

Answer:

The coordinates of point B are (6,7).

Step-by-step explanation:

Given points are

Blue = A(-4,8)

Purple = M(1,7.5)

Green = B

It is given that point M is the midpoint of point A and B.

Let coordinates of points are (a,b).

Midpoint of two points is

Midpoint=(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})

M=(\dfrac{-4+a}{2},\dfrac{8+b}{2})

Coordinates of midpoint are (1,7.5).

(1,7.5)=(\dfrac{-4+a}{2},\dfrac{8+b}{2})

On comparing both sides we get

1=\dfrac{-4+a}{2}\Rightarrow 2=-4+a\Rightarrow a=6

7.5=\dfrac{8+b}{2}\Rightarrow 15=8+b\Rightarrow b=7

Therefore, the coordinates of point B are (6,7).
