Answer:
around 4.1
Step-by-step explanation:
Answer: y=3/5x-4
Step-by-step explanation:
the slope is rise/run
the y intercept is where the line meets the y axis
Assuming this is quadrant one it would be 1,9 after moving left 8 and 5,9 after moving 4 right

<h3>Answer :</h3>
The factor of (x + y)³- (x³ + y³) is <u>3xy</u>
<h3>Step By Step Solution :</h3>
→ (x + y)³- (x³ + y³)
→ (x + y) - (x + y)(x² - xy + y²) [Using identity a³ + b³ = (a + b)(a²- ab+ b²)]
→ (x + y)(x² + y² + 2xy - x² + xy - y²)[Using identity, (a + b)² = (a² + b²+ 2ab)]
→ (x + y) (3xy)
→ 3xy
∴ Option d. 3xy is correct!

1. The semi inter quartile range is 10
2. The coefficient of quartile deviation is 0.2
<h3>1. How to determine the semi inter quartile range</h3>
- Mark: 20, 30, 40, 50, 60
- Freq: 5, 12, 27, 40, 50
- Com. freq: 5, 17, 44, 84, 134
- Semi inter quartile range =?
1st quartile (Q₁) = (134 + 1) / 4 = 33.75th = 40
3rd quartile (Q₃) = 3 (134 + 1) / 4 = 3 × 33.75 = 101.25th = 60
Semi inter quartile range = (Q₃ - Q₁) / 2
Semi inter quartile range = (60 - 40) / 2
Semi inter quartile range = 10
<h3>2. How to determine the coefficient</h3>
- 1st quartile (Q₁) = 40
- 3rd quartile (Q₃) = 60
- Coefficient of quartile deviation =?
Coefficient of quartile deviation = (Q₃ - Q₁) / (Q₃ + Q₁)
Coefficient of quartile deviation = (60 - 40) / (60 + 40)
Coefficient of quartile deviation = 0.2
