Answer:
42/49 is the fraction
Step-by-step explanation:
you can't simplify so put the amount correct over the amount total.
Given:
![\bold{ 8x=4y-20} \\\\ \bold{ y=13}](https://tex.z-dn.net/?f=%5Cbold%7B%208x%3D4y-20%7D%20%5C%5C%5C%5C%20%5Cbold%7B%20y%3D13%7D)
Prove:
![\bold{x=4}](https://tex.z-dn.net/?f=%5Cbold%7Bx%3D4%7D)
Solution:
![\to \bold{8x=4y-20}..........(i)\\\\\to \bold{ y=13}........................(ii)](https://tex.z-dn.net/?f=%5Cto%20%5Cbold%7B8x%3D4y-20%7D..........%28i%29%5C%5C%5C%5C%5Cto%20%5Cbold%7B%20y%3D13%7D........................%28ii%29)
Putting the value of equation (ii) into the equation (i):
![\to \bold{8x=4(13)-20}\\\\\to \bold{8x=52-20}\\\\\to \bold{8x=32}\\\\\to \bold{x=\frac{32}{8}}\\\\\to \bold{x= 4}\\\\](https://tex.z-dn.net/?f=%5Cto%20%5Cbold%7B8x%3D4%2813%29-20%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B8x%3D52-20%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B8x%3D32%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7Bx%3D%5Cfrac%7B32%7D%7B8%7D%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7Bx%3D%204%7D%5C%5C%5C%5C)
putting the value x into the equation (i):
![\to \bold{8(4)=4y-20}\\\\\to \bold{32=4y-20}\\\\\to \bold{32+20=4y}\\\\\to \bold{52=4y}\\\\\to \bold{y=\frac{54}{4}}\\\\\to \bold{ y= 13.5}](https://tex.z-dn.net/?f=%5Cto%20%5Cbold%7B8%284%29%3D4y-20%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B32%3D4y-20%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B32%2B20%3D4y%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B52%3D4y%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7By%3D%5Cfrac%7B54%7D%7B4%7D%7D%5C%5C%5C%5C%5Cto%20%5Cbold%7B%20y%3D%2013.5%7D)
Therefore, the value of x= 4

This triangle is a right angled triangle as we can see ∠POC, has a right angled sign. Now, we will assume the missing angle to be x, thus,
25° + 90° + x = 180° ( Angle sum property of a triangle )
115° + x = 180°
x = 180° - 115°
x = 65°
Thus, the measure of missing angle is 65°.
Hope that helps. :D
Based on the information in the table, an example of independent events is the: P(policer officer and chooses car).
<h3>What is an
independent event?</h3>
An independent event can be defined as an event that isn't dependent on other events. Thus, it isn't affected by any previous event.
Based on the information provided, we can infer and logically deduce that an example of independent events is the probability of being a policer officer and chooses a car because they aren't overlapping probabilities.
