To find the mean of this set of data you must add all the numbers together, then divide by the numbers that you have. Since you have 5 numbers you would divide by 5 after adding them together.
1st: ADD!!
20 + 12 + 29 + 15 + 49 = 125
2nd: divide by 5!
125 ÷ 5 = 25
So the mean of this data set is 25.
Good Luck! :)
We know that
A difference of two perfect squares (A² - B²) <span>can be factored into </span><span> (A+B) • (A-B)
</span> then
x ^4-4--------> (x²-2)*(x²+2)
(x²-2)--------> (x-√2)*(x+√2)
x1=+√2
x2=-√2
the other term
(x²+2)=0-> x²=-2-------------- x=(+-)√-2
i <span> is called the </span><span>imaginary unit. </span><span>It satisfies </span><span> i</span>²<span> =-1
</span><span>Both </span><span> i </span><span> and </span><span> -i </span><span> are the square roots of </span><span> -1
</span><span>√<span> -2 </span></span> =√<span> -1• 2 </span><span> = </span>√ -1 •√<span> 2 </span> =i • <span> √<span> 2 </span></span>
The equation has no real solutions. It has 2 imaginary, or complex solutions.
x3= 0 + √2<span> <span>i
</span></span>x4= 0 - √2<span> i </span>
the answer is
the values of x are
x1=+√2
x2=-√2
x3= 0 + √2 i
x4= 0 - √2 i
Answer:
The equations describing the area which each tower covers are given as
Tower A : 
Tower B : 
Tower C : 
Step-by-step solution:
Cell phone radio towers broadcast a cell phone signal in circular pattern
Tower A at Adele Acres have position co-ordinates as (0,0) and a coverage radius of 4 ml. So, the area which it covers is given by the equation,
-------------------------------(1)
Tower B at Brown Lake have position co-ordinates as (5,4) and a coverage radius of 3 ml. So, the area which it covers is given by the equation,
-------------------------------(2)
Tower C at Cady City have position co-ordinates as (4,-4) and a coverage radius of 5 ml. So, the area which it covers is given by the equation,
-------------------------------(2)
Answer:
An equation is used when we have paired sets of data to describe how the values in one pair change when we alter the values in the other set.
On the other hand, a series gives a general formula of determining the value of the nth observation when the values have been arranged in increasing order
Step-by-step explanation:
An equation such as; y = 3x+5 models the relation between the response variable y and the predictor variable x. It tells us how y changes when x is altered by a certain magnitude. The value 3 is described as the slope while 5 is the y-intercept.
On the other hand, a series such as; score = 2 + 3n provides a general formula that can be used to determine the score of the nth individual in a sample or population.
Answer:
E)82
Step-by-step explanation:
The formula is
A^2 + B^2= C^2
the two sides that make up the right angle is always A and B
