1. Slope 3/4, through (4,-1)

y = 3/4 x + b

-1 = 3/4(4) + b

-1 = 3 + b

-1 - 3 = b

-4 = b

y = 3/4 x - 4

2. Slope = - 1/2, through (3,0)

y = -1/2 x + b

0 = -1/2(3) + b

0 = -1.5 + b

0 + 1.5 = b

1.5 = b

y = -1/2 x + 1.5

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)

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

$P(n>55)=0.1357$
