Confusing to me, sorry i cant help. I am not good with graphs.
Answer:
Step-by-step explanation:
4(5x-2y=9)
-2(3x+4y=-5)
20-20x-8y=36
+6x-6x-8y=10
36-20x=10+6x-6x
36-36-20x-6x=10
-26x=10-36
-26x/-26=-26/-26
x=1
30 percent is 30/100 as a fraction so as a decimal it would be 0.30
In the given question there are numerous important information's available. using these information's the answer can be easily deduced. The total number of red roses that Grandma has is already mentioned in the question and it is 14. The total number of pink roses that grandma has is also mentioned in the question and that is 7. Now this is a simple question and the required answer can be reached by simply subtracting the number of pink roses from the number of red roses.
The number of more red roses than pink roses grandma has = 14 - 7
= 7
So Grandma has 7 more red roses than pink roses.
To solve the question we use the following analogy:
Given that the odds of winning is a/b, then the probability is b/(a+b)
hence to solve the question we proceed as follows:
a]
P(E)=11/36
odds against E=(36-11)/11
simplifying this gives us:
25/11
b] P(E)=31/36
odds against E=(36-31)/31
simplifying this we get:
5/31
hence odds in favor of E=31/5
c]P(E)=32/36
odds in favor of E will be:
36/(36-32)
simplifying the above we get:
36/4
=9/1
d]
P(E)=30/36
odds against E will be:
(36-30)/36
simplifying this we obtain:
6/36
=1/5
e] P(E)=13/36
odds against E will be:
(36-13)/13
simplifying this we obtain:
23/13
