A single outlier causes the value of the median to move slightly away
Answer:
-3.5,-0.2,0.6,5 ... is the answer
Answer:
x=5 x = -3
Step-by-step explanation:
-7 / ( x^2 -2x -15)
Factor the denominator
-7
----
(x-5) ( x+3)
The excluded values are when the denominator is equal to zero
(x-5) (x+3) =0
x-5 =0 x+3=0
x=5 x = -3
35 more than 8 times a number
.Let that number be x
35 more than 8 times the number x is written as 35+8x
And 43 less than the product of -7 and the number is written as 43 - -7x
=43+7x
and from the question, the two equations are equal,so we just place the equal sign between the two expression and solve for X
Thus
35+8x=43+7x
Grouping of like terms
8x-7x = 43-35
X = 8 .
Perimeter of triangle ABC is 20 units.
Solution:
The image for reference is attached below.
Given AE = 2, BD = 5 and CF = 3
Two tangents drawn from an external point to a circle are equal in length.
AD = AE, BF = BD and CE = CF
Therefore, AD = 2, BF = 5 and CE = 3
Perimeter of the triangle = sum of the three sides
Perimeter of triangle ABC = AB + BC + CA
= AD + BD + BF + CF + CE + AE
= 2 + 5 + 5 + 3 + 3 + 2
= 20
Hence, perimeter of triangle ABC is 20 units.
