If the smaller number is x, then the larger number has to be 20 - x in order for the arithmetic mean to be 10, as their sum must be 20.
If the geometric mean is 8 the product of the numbers has to be 64 and so the larger number is 64/x
Solving 64/x = 20 - x gives the quadratic x^2 -20x +64 = 0 so x = 4 or 16.
The two numbers are 4 and 16.
25 + 35 = 60
300/60 = 5
the answer is 5 packets
The margin of error is ±2%
<h3>What is Margin error?</h3>
A margin of error is a statistical measurement that accounts for the difference between actual and projected results in a random survey sample.
Let x be margin of error and y be the percentages of the population.
So,
y-x =33%
y +x = 37%
Solving above equations
2y= 70
y= 35%
and x= 2%
Hence, the margin of error is ±2%.

Answer:
The value of x for the given expression is 5 .
Step-by-step explanation:
Given expression as
+
= 
Now, arrange the equation
So,
=
- 
<u>Taking L.C.M on right hand side </u>
Or,
=
Or,
=
Or, x = 
∴ x = 5
So, The value of x = 5
Hence,The value of x for the given expression is 5 . Answer
Answer:
Step-by-step explanation:
Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.
