Answer:
x = - 27/8
Step-by-step explanation:
¹²⁾x/5 - ¹²⁾1/5 = ²⁰⁾x/3 + ¹⁵⁾1/4
12x - 12 = 20x + 15
- 12 - 15 = 20x - 12x
- 27 = 8x
x = - 27/8
<span>The
population standard deviation is unknown, sample size is less than 30,
and the population has a normal or near-normal distribution</span>.
Answer:
x = 4
Step-by-step explanation:
2x - y = 11
X + 3y = -5
Multiply the first equation by 3
3(2x - y )= 11*3
6x - 3y = 33
Add this to the second equation to eliminate y
6x - 3y = 33
X + 3y = -5
--------------------
7x = 28
Divide by 7
7x/7 = 28/7
x = 4
Answer:
0 < x ≤ 200 and 0 < y ≤ 400
Step-by-step explanation:
hope this helps
