So the angle that's next to the 62 is 118. Now that means the other angles have to add up to 62. 62-14= 48 and 48/2 is 24 so X=24. Good luck! :)

Ainat [17]

Answer:

The test statistic Z = 3.125

Step-by-step explanation:

Given Population proportion P = 0.25

Given sample size 'n' = 696

Sample proportion 'p⁻' = 0.30

Test statistic

$Z = \frac{p^{-} -P}{\sqrt{\frac{P Q}{n} } }$

$Z = \frac{0.30-0.25}{\sqrt{\frac{0.25 X 0.75}{696} } } = 3.125$

Final answer:-

The test statistic Z = 3.125

Answer:

Part a) $AB=15\ cm$

Part b) $AB=11.1\ cm$

Part c) $AB=3/5\ cm$

Part d) $AB=3s\ cm$

Step-by-step explanation:

see the attached figure to better understand the question

we know that

To find the length of the image after a dilation, multiply the length of the pre-image by the scale factor

Part a) we have

The scale factor is 5

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

$3(5)=15\ cm$

Part b) we have

The scale factor is 3.7

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

$3(3.7)=11.1\ cm$

Part c) we have

The scale factor is 1/5

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

$3(1/5)=3/5\ cm$

Part d) we have

The scale factor is s

The length of the pre-image is 3 cm

therefore

The length of the image AB after dilation is

$3(s)=3s\ cm$

Let f(x)=1/x and g(x)=x^2-2x What two numbers are not in the domain of f o g?

Brrunno [24]

Answer:

First find f o g (x)

f o g (x) = 1 / x² - 2x

To find the numbers which are not in the domain of f o g equate the denominator to zero

x² - 2x = 0

x(x - 2) = 0

x = 0 and x = 2

The two numbers which are not in the domain of f o g are 0 and 2.

Hope this helps.
