Calculate mean:
4+3+4+5+6+6+8+4=40
40/8=5
Calculate MAD:
1+2+1+0+1+1+3+1=10
10/8= 1.25
Final answer: 1.25
Answer:
21 + 25i√3
Step-by-step explanation:
⇒ equation: (p√−3)+q
⇒ p = 25
⇒ q = 21
<em>Plug in:</em>
((25)√−3) + 21
√−3 = i√3
25i√3 + 21
Answer:

Step-by-step explanation:
The given quadratic functions are:



We want to order these functions, from the widest to the narrowest.
How wide the graph will open depends on the absolute value of the coefficient of the function.
The smaller the absolute value of the coefficient, the wider the graph.
Since

Therefore from the widest graph to the narrowest graph, we have:

Answer: A B
Group A 0.25 0.75
Group B 0.45 0.55
Step-by-step explanation:
Since we have given that
Number of people of A in Group A = 15
Number of people of B in Group A = 45
Number of people of A in Group B = 20
Number of people of B in Group B = 25
Total number of people in Group A = 15+45 = 60
Total number of people in Group B = 20+25 = 45
So, Relative frequencies will be given below:
Relative frequency of A in Group A is given by

Relative frequency of B in Group A is given by

Relative frequency of A in Group B is given by

Relative frequency of B in Group B is given by

Hence, A B
Group A 0.25 0.75
Group B 0.45 0.55
2 would be "B" and 3 would "D"
