</u>
<em>A. More churches lead to more crimes. </em>
<u>Solution-</u>
Properties of Correlation Coefficient,
1- A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.
2- A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.
Here,there is a positive correlation between the number of churches and the city’s crime rate. So as the number of churches increase, the crime rate also gets increased.
Domain: x values
Range: y values
The relation would need to have (2, y) and (4, y). And also (x, 2) and (x, 8)
See which ones match
Solution: B
We have to determine the value of 
= (5(9)+6) + (5(10)+6) +(5(11)+6) + .......... + (5(21)+6)
= 51+56+61+66+ ........ + 111
Since, the common difference is 5, hence this series is in arithmetic progression.
Sum of AP is given by the formula:
![\frac{n}{2}[2a+(n-1)d]](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B2%7D%5B2a%2B%28n-1%29d%5D)
Since, there are 13 terms.
= ![\frac{13}{2}[2(51)+(13-1)5]](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D%5B2%2851%29%2B%2813-1%295%5D)
= ![\frac{13}{2}[102+60]](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D%5B102%2B60%5D)
= ![\frac{13}{2}[162]](https://tex.z-dn.net/?f=%5Cfrac%7B13%7D%7B2%7D%5B162%5D)
= 
= 1053
Therefore, the sum of the series is 1053.
So, Option G is the correct answer.
Rotation: a b
Translation:e j
Reflection over a horizontal line: g f
Reflection over a vertical line: c e
Rotation then reflection: a h
Rotation then translation: a d
I’m sorry if this isn’t right
Use cymath it can really help you cause in here you can barely do it
