Answer:
Step-by-step explanation:
320:60 you have to find the multiples I am not going to give you the full answer that is cheating
<span>The solution:
= 40, p = q = 0.5
P[x] = nCx *p^x *q^(n-x)
when p = q = 0.5, the formula simplifies to
P[x] = nCx/2^n = 40Cx/2^40
at least 18 of each type means 18 to 22 of (say) type I
P(18 <= X <= 22) = 0.5704095 <-------
qb
mean = 40*0.5 = 20
SD = sqrt(npq) = sqrt(40*0.5*0.5) = 3.1623
z1= (18-20)/3.1623 = -0.63 , z2 = (22-20)/3.1623 = 0.63
P(-0.63 < z < 0.63) = 0.4713 <-------</span>

I believe we add the two together and get our total !

Answer:
Step-by-step explanation:
use trigonametry
a^2+b^2=c^2
x^2+38^2=41^2
x^2=237

Answer:
500 students.
Step-by-step explanation:
300 votes is 60%.
100%-60% is 40%
so 40% voted for the other person.
Work backwards:
x * 0.6=300
0.6x=300
x=300/0.6 which is 500.
500*0.4 is 200.
300+200 is 500.
Hope this helps :) I am terribly sorry if it is wrong or not using the number line.
