Answer:
5
Step-by-step explanation:
d=√(7−3)^2+(5−2)^2
d=√(4)^2+(3)^2
d=√16+9
d=2–√5
d=5
Answer:
8.6615988
Step-by-step explanation:
f(x) = 3 sin (x) / ( 1 + cos x)
To find the derivative bottom * d/ dx top - top d/dx bottom all over the bottom squared
d/dx = 3 ( ( 1 + cos x) cos x - sin x( - sin x)) / ( 1 + cos x) ^2
= 3 ( cos x + cos ^2 x + sin ^2 x) / ( 1 + cos x) ^2
= 3 ( 1 + cos x) / ( 1 + cos x) ^2
= 3 / ( 1 + cos x)
Let x = 4
3 / ( 1 + cos 4)
Assuming x is in radians
3/.346356

Answer:
The approximate probability of winning 4 games in a row is 0.012
Step-by-step explanation:
From the question, the probability of winning the shell games if you randomly pick is 1 in 3, that is,
P(Win) = 1/3
Now, the probability of winning 4 games in a row will be
P (winning 4 games in a row) = P(winning 1st game) × P(winning 2nd game) × P(winning 3rd game) × P(winning 4th game)
P (winning 4 games in a row) = (1/3) × (1/3) × (1/3) × (1/3)
P (winning 4 games in a row) = 1/81 or 0.012
Hence, the approximate probability of winning 4 games in a row is 0.012
Answer: They are diffrent
Step-by-step explanation: The logistic equation was first published by Pierre Verhulst in 1845. This differential equation can be coupled with the initial condition P(0) = P0 to form an initial-value problem for P(t). Suppose that the initial population is small relative to the carrying capacity. Then P K is small, possibly close to zero.
The logistic regression coefficients are the coefficients b 0, b 1, b 2,... b k of the regression equation: An independent variable with a regression coefficient not significantly different from 0 (P>0.05) can be removed from the regression model (press function key F7 to repeat the logistic regression procedure).
