Mathematics
1 answer:
Dominik [7]2 years ago

Answer:

X = 30°, y = 15° and z = 150°.

Reason: Look below.

Step-by-step explanation:

Hey there!

When we look into the figure, we find that;

For x:

x+ 2x + 90° = 180° {Being linear pair}

or, 3x = 180°-90°

or, 3x = 90°

or, x= 90°/3

<u>Therefore, X = 30°.</u>

For y :

2y = x = 30° {Alternate angles are equal}

or, 2y = 30°

y = 30°/2

<u>Therefore, y = </u><u>1</u><u>5</u><u>°</u>

For z:

2y + z = 180° { Being linear pair}

or, 30°+z = 180°

or, z = 180°-30°

or, z = 150°

<u>Therefore, z = 150°.</u>

What is the slope of the line that passes through the points (2,0) and (1,0)? Write
ICE Princess25 [194]

Answer:

m=0

Step-by-step explanation:

The slope of a line can be found using:

m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }

Let's call (2,0) our "2" coordinate, and (1,0) our "1" coordinate.

Coordinates are written as: (x,y)

Therefore, our x2 is 2 and y2 is 0. Our x1 is 1 and y2 is 0.

Substitute these values into the formula .

m=\frac{0-0}{2-1}

m=\frac{0}{1}

m=0

The slope of the line is 0

The standard deviation of a sample taken from population A is 17.6 for a sample of 25.
lawyer [7]

Answer:

The standard deviation of the sample mean differences is _5.23_

Step-by-step explanation:

We have a sample of a population A and a sample of a population B.

For the sample of population A, the standard deviation \sigma_A is

\sigma_A = 17.6

The sample size n_A is:

n_A = 25.

For the sample of population B, the standard deviation \sigma_B is

\sigma_B = 21.2

The sample size n_B is:

n_B = 30.

Then the standard deviation for the difference of means has the following form:

\sigma=\sqrt{\frac{\sigma_A^2}{n_A}+\frac{\sigma_B^2}{n_B}}

Finally

\sigma=\sqrt{\frac{17.6^2}{25}+\frac{21.2^2}{30}}\\\\\sigma= 5.23
