Answer:

z= 117°

y = 34

Hope it helps!

Step-by-step explanation:

(5y - 53) + 63 =180°

5y + 10 =180

5y = 170

y= 34

z and y are congruent (vertical angles)

5 (34) - 53 = z

170 - 53 = z

z = 117

You can use the rules of parallel angles for these so the angles within the c shape add up to 180, this means that z=117 degrees (180-63=117) now you can workout what y is as opposite angles on a point are equal to each other therefore (5y-53) will equal 117
So now you can use this and rearrange to find y
So 5y-53=117
5y=117+53 as the sign changes
5y=170
y=170/5
y=34

What is the r-value of the following data, to three decimal places

Mrrafil [7]

<h2>Answer:</h2>

Option: A is the correct answer.

A. -0.903

<h2>Step-by-step explanation:</h2>

The formula to calculate correlation coefficient r is given by:

$r=\dfrac{n\sum xy-(\sum x)(\sum y)}{\sqrt{n(\sum x^2)-(\sum x)^2}\sqrt{n(\sum y^2)-(\sum y)^2}}$

x y xy x² y²

4 23 92 16 529

5 12 60 25 144

8 10 80 64 100

9 9 81 81 81

13 2 26 169 4

-------------------------------------------------------------------------

∑ 39 56 339 355 858

Also n=5 ( as there are 5 data points )

Hence, we get:

$r=\dfrac{5\times 339-39\times 56}{\sqrt{5\times 355-(39)^2}\times \sqrt{5\times 858-(56)^2}}\\\\\\r=\dfrac{-489}{\sqrt{254}\times \sqrt{1154}}\\$

$r=-\dfrac{489}{541.40188}=-0.9032$

Hence, the r-value of the following data, to three decimal places is:

A. -0.932

Solve : <br><br>1) 5x – 15x²<br>2) 3x-9

8090 [49]

Answer:

1) 5x(1 - 3x)

2) 3(x - 3)

Step-by-step explanation:

<u>Question # 1:</u>

= 5x - 15x²

Take 5x common

= 5x(1 - 3x)

<u>Question # 2:</u>

= 3x - 9

Take 3 common

= 3(x - 3)

$\rule[225]{225}{2}$

Hope this helped!

-19 to -15 would be a positive 4 difference

19 to 15 = 4 this would be a -4 difference

3 to 7 is a positive 4 difference

-3 to 7 is a difference of 10

so there is 1 with a -4 difference
answer is B.
