if you go to study jam.
click math or search geometry.
then search 'Transformation'
in the video it talks about: Reflection, Translation, and Rotation

By translating a shape, you are basically moving it around the graph. For example, one of the points of your shape could be on the origin (0,0). You could then translate it 4 units up and 6 units to the left. You would write this translation as (x-6, y+4). If you were starting at (0,0) your point translation would be at (-6, 4), but if you were to translate a point at (1, 1) your translated point would be at (-5, 5).

Over the past several years, the proportion of one-person households has been increasing. The Census Bureau would like to test t

Ganezh [65]

Answer: z =2.39

Step-by-step explanation:

Given :

$H_0: p \leq0.23\\\\ H_a: p > 0.23$

A random sample of 136 households found that 43 consisted of one person.

i.e. Sample size : n= 136

Sample proportion : $\hat{p}=\dfrac{43}{136}=0.316176470588\approx0.3162$

Test statistic for proportion :-

$z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

$\Rightarrow z=\dfrac{0.3162-0.23}{\sqrt{\dfrac{0.23(1-0.23)}{136}}}\\\\\Rightarrow\ z=\dfrac{0.0862}{\sqrt{0.00130220588235}}\\\\\Rightarrow\ z=\dfrac{0.0862}{0.0360860898734}\\\\=2.38873206552\approx2.39$

Hence, the value of the test statistic: z =2.39

Answer:

Step-by-step explanation:

You can use a graphing calculator like desmos or draw your own graph to figure this out. Start by graphing each of those points. Then count the width and height. Multiply them to get the area. The width and height of the rectangle were 6 and 8, so the area is 48

What’s a absolute deviation

Sergeeva-Olga [200]

Answer:

Absolute deviation is when you find the mean of a data set, then the difference between each number and the mean, then the average f the differences.

Step-by-step explanation:

Maddox: |10-9| = 1

Enrique: |10-13| = 3

Gloria: |10-9| = 1

McKenna: |10-10| = 0

Asher: |10-9| = 1

Hannah: |10-9| =

Danielle: |10-10| = 0

Katy: |10-10| = 0

Timothy: |10-11| = 1

Gentry: |10-9| = 1

Now you have the numbers: 1, 3, 1, 0, 1, 1, 0, 0, 1, 1,

Now find the mean of those numbers:

$\frac{1 + 3+1+0+1+1+1+0+0+1+1}{10} =\frac{10}{10} =1$

The absolute deviation is 1.

What is the value of x? Enter your answer in the box. x =____cm

MrRa [10]

Answer:

x = 5 cm

Step-by-step explanation:

We can use proportions of similar triangles. Put the side of the small triangle over the same side of the large triangle

x 4

---------- = -----------

40 32

Using cross products

32x = 4*40

32x = 160

Divide by 32

32x/32 = 160/32

x=5
