Answer:
(x+8)^2 - 60 = 0
Step-by-step explanation:
x^2 + 16x + 4 = 0
x^2 + 16x + 64 - 60 = 0
(x + 8)^2 - 60 = 0
Answer:
Expected Number=71
Variance =4959
Standard Deviation= 70.42
Step-by-step explanation:
Expected Number = E (x) = np
Here p = 0.71 and q= 1- 0.71= 0.29 n= 100
Expected Number = E (x) = np = 0.71*100= 71
b) The Variance and Standard Deviation for the number of these tweets with no reaction
Suppose the number of tweets are hundred then the number of tweets with no reaction would be 71 .
Variance = E(x²) - [E(x)]² = (100)²- (71)²= 10000- 5041= 4959
Standard Deviation= √4959= 70.42
Answer:
0 of a polynomial is that point where the graph cuts the x axis so the answer is
