Answer:

1/20

Step-by-step explanation:

-2 1/3=-5/3=-10/6

7 1/6=43/6

-10/6*4=-40/6

-40/60+43/60=3/60=1/20

Consider the equation below. (If an answer does not exist, enter DNE.)f(x) = x2 − x − ln(x)

Morgarella [4.7K]

Answer:

a) decreasing from (0,2), increasing from (2,∞ )

b) local minimum in x=2 . there is no maximum or minimum value

c) DNE. there is no inflexion point

Step-by-step explanation:

f(x) = x² - x - ln (x)

since ln(x) is defined for positive values only x must be greater than 0 (x>0)

also we will need the first derivative and the second derivative with respecto to x

f(x) = x² - x - ln (x)

df/dx (x) = 2x - 1 - 1/x

d²f /(dx)² (x) = 2 + 1/x²

a) to find the increasing and decreasing intervals we will need to evaluate the rate of change (df/dx) :

df/dx = 0 when 2x - 1 - 1/x = 0 → 2x² - x - 1 = 0 → x = (1±√(1+8))/2 = (1 ± 3)/2

→ x1 = 2 , x2 = -1 (discarded because x2<0)

therefore since 2x increases and 1/x decreases with increasing x

for x > 2 , df/dx is positive and thus f increases with increasing x

for 0<x< 2, df/dx is negative and thus f decreases with increasing x

b) since f increases with increasing x for x> 2 and decreases with increasing x for, 0<x< 2 , f should be a minimum value.

we can verify it with the second derivative

d²f /(dx)² (x) =2 + 1/x² → for x >0 , d²f /(dx)² is always >0 therefore

d²f /(dx)² (x1) > 0 and df/dx (x1) =0 → thus f(x) is a local minimum of x

there are no maximum values since for x → ∞ , f(x) → ∞ and for x→ 0 → f(x) → -∞ (because of the ln(x) function)

c) there are no inflexion points since d²f /(dx)² (x1) is always greater than 0 for x>0

It has been observed that a large percentage of professional hockey players have birthdays in the first part of the year. It has

vagabundo [1.1K]

Answer:

$\mu = 127$

$\sigma = 9.76$

$z-score = 3.18$

Yes, 158 players out of 508 is an unusual number of men born in the first 3 months of the year because the z score of 158 is greater than 3( Note :the probability of z-score = 3 is 97%)

The correct option is option 3

Step-by-step explanation:

From the question we are told that

The population proportion is p = 0.25

The sample size is n = 508

Generally the mean is mathematically represented as

$\mu = np$

=> $\mu = 508 * 0.25$

=> $\mu = 127$

Generally the standard deviation is mathematically represented as

$\sigma = \sqrt{ np (1-p)}$

=> $\sigma = \sqrt{ 508 * 0.25 (1-0.25)}$

=> $\sigma = 9.76$

Generally the z-score of 158 is mathematically represented as

$z-score = \frac{158 - 127}{9.76}$

=> $z-score = \frac{158 - 127}{9.76}$

=> $z-score = 3.18$

Yes, 158 players out of 508 is an unusual number of men born in the first 3 months of the year because the z score of 158 is greater than 3( Note :the probability of z-score = 3 is 97%)

What this means is that the almost the whole professional hockey league player are born in the first month which is unusual
