3p+4q=10
5p-4q=-26
Add both equations
3p+4q+5p-4q=10-26
8p=-16
p=-2
3p
3p+4q=10
3(-2)+4q=10
-6+4q=10
4q=16
q=4
(-2,4)
2/5 is the smallest fraction. Your welcome.
The answer to the above question is Yes. They are mutually exclusive events.
The mutually exclusive events are events which cannot occur at the same time. Suppose, you toss a coin, there cannot be head and tails both as outcomes at the same time. So, occurring of heads and tails on a coin when tossed, is an example of mutually exclusive event.
Similarly, when you roll a cube, you can never have two numbers together on the cube as outcome. <u>So, rolling a 4 and rolling a 3 on a standard number cube is a mutually exclusive events.</u>
Stratified sampling is the sampling method which is the most appropriate for determining the mean number of students per statistics class in your state.
<h3>What is Stratified sampling method?</h3>
This method involves dividing subjects into subgroups known as strata according to shared features.
To determine the mean number of students per statistics class in your state, the state should be divided into strata based on the area, then some statistics classes are then selected for further analysis so as to determine the number of students per statistics class in the state.
This is therefore the reason why Stratified sampling method was chosen as the appropriate choice.
