The Normal approximation to the binomial
<span>is as follows
</span>
<span>mean=13(.5)=6.5 </span>
<span>variance=6.5(.5)=3.25 </span>
<span>Pr[fewer than 4]= </span>
<span>Pr[N<=3] Apply the continuity correction </span>
<span>Pr[N<=3.5]~=Pr[Z<3.5-6.5/sqrt(3.25)]=
</span>
<span>Pr[Z<-1.66]=0.048457226
I hope my answer has come to your help. God bless and have a nice day ahead!</span>
Answer:
x=$2.50, y=$4.00
Step-by-step explanation:
Let x=cost of the water slide
Let y=cost of the ferris wheel
System of equations:
3x+3y=19.50
2x+3y=17.00
Subtract the 2nd from the 1st to get:
x=2.50
Now plug into first equation to get:
3(2.50)+3y=19.50 so y=4.00
Check in 2nd equation:
2(2.50)+3(4) = 5+12 = 17
