Answer:
x = 26
Step-by-step explanation:
1 / 3 (x - 2) = 1 / 5 (x + 4) + 2
1/3x - 2/3 = 1/5x + 4/5 + 2
1/3x - 1/5x = 4/5 + 2/3 + 2
(5x - 3x)/15 = (12 + 10 + 30) / 15
2x / 15 = 52 / 15
2x = 52
x = 52 / 2
x = 26

Answer:
Chords and secants intersect the perimeter of a circle twice. Chords are segments entirely within a circle, while secants are lines or rays that extend through a circle.
Explanation:
A line intersecting a circle in two places is referred to as a secant. The portion of the secant contained within the circle is called a chord.
This means that both chords and secants intersect the perimeter of a circle twice, chords are entirely inside the circle, and secants extend through a circle to the outside.
Answer:
Step-by-step explanation:
From the information given :
The null hypothesis 
The alternative hypothesis 
Given that:
the sample size n = 21
sample standard deviation s = 68
population standard deviation σ = 60
a) The level of significance 
b) The chi-square statistics can be calculated as:




The degree of freedom is :
= n - 1
= 21 - 1
= 20
Answer:Infinite solution
Step-by-step explanation:
For Inequalities

3y-6x>2
and 
3y-6x<1
The required Inequalities have no solution because they do not share the common region for a common solution
But if signs of both inequalities is changed then the system has infinite number of solution.

3y-6x<2
and 
3y-6x>1
