Answer: 25 computers will be selected
Step-by-step explanation:
Where: Z -value at 95% confidence = 1.96; SD = Standard deviation = 10 minutes; N = Sample size; Margin error = 4 minutesSubstituting;4 = 1.96*10/Sqrt (N)Sqrt (N) = (1.96*10)/4 = 4.9N = 4.9^2 = 24.01 ≈ 25
subtracting 9.1 - 12.9 is -3.8
(<u><em>A resposta):</em></u> O número de divisores em 1800 é de 36

Answer:
0.50
Step-by-step explanation:
P(A|B)=P(A and B)/P(B) is the formula to find a conditional probability when A and B are not independent.
A and B are independent. This means B has no effect of A. This means P(A|B)=P(A).
P(A|B)=P(A) since A and B are independent
P(A|B)=0.50
Answer:
P=(3,3)
Step-by-step explanation:
We need to find a point P in the line such that where
Observe that the coordinates of P are because P is in the line.
Then,
We reeplace the value of x in the coordinates of P and obtain the point
