Answer:
12 5/12 i think
Step-by-step explanation:
Answer:
b.
Step-by-step explanation:
The function forms an U line in a graph not a straight line
I think it’s y=1.4x, but I don’t really know.
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

A) The function f+g is just the sum of the 2 functions f and g.
The derivative of f+g is also just the sum of the derivatives.
So to find slope of new tangent line, you find sum of the slopes for f and g.
---> m = 2+2 = 4
The point on new curve is (4, f(4)+g(4)) -----> (4,17)
The equation of tangent line is then:
y - 17 = 4(x -4)
y = 4x + 1
b) and c) are done the same way. f-g means subtract slopes.
2f means double slope etc...
