never [62]

Answer:

$P(n>55)=0.1357$

Step-by-step explanation:

From the question we are told that:

Sample size n=100

Sample space n'=36

Generally the equation for the mean number of times odds appears is mathematically given by

$\=x_o=hp$

$\=x_o=100*0.5$

$\=x_o=50$

Generally the equation for standard deviation is mathematically given by

$\sigma=(hp(1-p))^{1/2}\\\sigma=(50(0.5))^{1/2}$

$\sigma=5$

Therefore probability to make wrong decision P(n>55)

$P(n>55)=1-P(z55)=1-P(z55)=1-0.86$

$P(n>55)=0.1357$

I need help on this question

Pie

Answer:

(f-g)(4) = 10

Step-by-step explanation:

(f-g)(x) = f(x) - g(x)

= 1/2 x^2 - 1/4 x + 4 - 1/2 x + 1

= 1/2 x^2 - 1/4 x - 1/2 x + 4 + 1

= 1/2 x^2 - 3/4 x + 5

(f-g)(4)

= 1/2 (4)^2 - 3/4 (4) + 5

= 1/2 * 16 - 3 + 5

= 8 - 3 + 5

= 5 + 5

= 10
