Just substitute the value of x from second equation into first equation:
N = x + y - n = 5
N = u + v + y - n = 5
N = 0 + y - n = 5
In short, N would be equal to y - n which is still equal to 5
Hope this helps!
Answer:
0.9562
Step-by-step explanation:
Binomial probability is mathematically expressed as:

Given that p=0.18, n=5 , is calculated as:

Hence, the probability of no more than 2 successes in 5 trials is 0.9562
Answer:
The Amin's score in math was 46.
Step-by-step explanation:
The question is:
The average math score for Amin, azman and aziz is 73. Azman marks 35 more than Amin while aziz is twice that of Amun. What is Amin's sign?
Solution:
Let us denote that:
<em>x</em> = Amin's score in math
<em>y</em> = Azman's score in math
<em>z</em> = Aziz's score in math.
The average of <em>x</em>, <em>y</em> and <em>z</em> is, 73.
That is:

Now it is provided that:

Use the equations (i) and (ii) to determine the value of <em>x</em> as follows:

Thus, the Amin's score in math was 46.
So basically what you have to do is first identify all of the sides or angles that equal eachother then you can see if you did a side side and side in a row etc, like 44 would be SAS because the vertical angles would be inbetween the two sides. 46 would be SSS because after you make the line in the middle for reflexive property you can see that there are three sides in a row.

Answer:
y=29
Step-by-step explanation:
Replace x with 7:
y=8+3(7)
Multiply 7 and 3:
y=8+21
Add together:
y=29
