Answer:
I just did the test and got it right the answer is A. Paul's data has a larger overall spread than Sally's data.
Step-by-step explanation:
Answer:
n + y
Step-by-step explanation:
a² - b² = (a +b)(a - b)
÷ 
{ (n + y) in the denominator and numerator will be cancelled ;
(n - y) in the denominator and numerator will be cancelled
= n + y

Answer:
- (4x -4)° +x° +(6x-3)° = 180°
- J = 99°
- K = 64°
- L = 17°
Step-by-step explanation:
The relation that helps you write an equation for x is, "the sum of angles in a triangle is 180°."
__
<h3>equation</h3>
(4x -4)° +x° +(6x -3)° = 180° . . . . . sum of angles in this triangle
<h3>solution for x</h3>
11x -7 = 180 . . . . . . . divide by °, collect terms
11x = 187 . . . . . . . . add 7
x = 17 . . . . . . . . . divide by 11
<h3>angle values</h3>
m∠J = (6x -3)° = (6(17) -3)° = 99°
m∠K = (4x -4)° = (4(17) -4)° = 64°
m∠L = x° = 17°

6 times 5 is 30 and since its 6 per hour you just do it to five :)
