Answer:
Step-by-step explanation:
mean = sum of data / no of data
20 + 58 + 74 + 77 + 77 + 85 + 86 + 90 + 95 + 98 / 10
760 / 10
76
to find median u should arrange the data from ascending to descending order.
since the given data is already arranged u dont need to change.
median = (N + 1)/2 (N means no of data)
=10 + 1 / 2
=11 / 2
=5.5
= 5 th term + 6 th term /2
=77 + 85 /2
=162 / 2
=81
mode means most repeating number . so in this given data 77 is repeated two times while others occured just one times . so the mode of the given data is 77.
Mode = 77
Answer:
The answer to your question is (x₁ - 4)(x₂ - 9)(x₃)(x₄ +4)
Step-by-step explanation:
Data
zeros of a polynomial = 4, 9, 0, -1
Process
1.- Equal each root to zero
x₁ = 4 x₂ = 9 x₃ = 0 x₄ = -1
x₁ - 4 = 0 x₂ - 9 = 0 x₃ = 0 x₄ + 1 = 0
2.- Write the terms together
(x₁ - 4)(x₂ - 9)(x₃)(x₄ +4)
3.- Expand to check the answer
(x - 4)(x - 9) = x² -13x + 36
(x² -13x + 36)(x) = x³ - 13x² + 36x
(x³ - 13x² + 36x)(x + 4) = x⁴ - 13x³ + 36x² + 4x³ - 52x² + 144x
= x⁴ - 9x³ - 16x² + 144
