The formula for geometric mean is nth root of the product of all terms. n denotes the number of data. Since you have only two points, 99 and 11, n = 2. The product of both terms is 99 × 11 = 1089. The square root of 1089 is 33. Thus, the answer is 33.
A Statistic.
Since they want to know how their magazine are, they are gonna make a survey. In the survey, the people are statistics to see how well their magazines are. With that, they can decide to change their subjects or whatever it is. Hope this helps!
Answer:
x=-1
Step-by-step explanation:
-5x=5
-x=1
x=-1
or solve this way
-5x=5
5x=-5
x=-1
The solution of simultaneous equations is x=4 and y = -1.
<h3>What are
Simultaneous equations?</h3>
Simultaneous equations are two or more algebraic equations with the same unknown variables and the same value of the variables satisfies all such equations.
We can solve simultaneous equations by various methods. here we will solve it by elimination method.
Here we have two simultaneous equations
3x -2y = 14 --- (i)
and 4x + 3y = 13---(ii)
Now multiplying (i) by 3 and (ii) by 2 we get
9x -6y = 42 and 8x + 6y = 26.
Now adding both we get
17x = 68 ⇒ x = 68/17 ⇒ x = 4.
Substituting the value of x in (i), we get
3*4 - 2y = 14 ⇒ -2y = 14-12 = 2 = -2/2 ⇒ y = -1.
Therefore, the values of x and y are 4 and -1 respectively .
