Answer:
x=4, y=1
Step-by-step explanation:
x + 3y = 7
x - 3y = 1
Add the equations together to eliminate y
x + 3y = 7
x - 3y = 1
---------------------
2x = 8
Divide by 2
2x/2 = 8/2
x = 4
Subtract the two equations to eliminate x
x + 3y = 7
-x + 3y = -1
----------------------
6y = 6
Divide by 6
6y/6 = 6/6
y =1

that is
Given:
Z=2.576 tabled value. Because Z is 2.4049, that's less than Z stated, there is no indication that a null hypothesis is rejectable, which means that 23% of all adults record the logo of the Company.
Answer:
<h3>
s = 16.2 units</h3><h3>
</h3>
Step-by-step explanation:
use Pythagorean theorem:
a² + b² = c²
where a = 12/2 = 6
b = 15
c = s
<u>plugin values into the formula:</u>
6² + 15² = s²
s = √(6² + 15²)
s = √261
s = 16.2 units
M/(30-15) = m/(30+15) + 1
m/15 = m/45 + 1
45*m/15 = 45*(m/45 + 1
3m = 45*(m/45) + 45*(1)
3m = m+45
3m-m = m+45-m
2m = 45
2m/2 = 45/2
m = 45/2
m=22.5
