Answer:24,825.85
V:4/3x3.14xr^3
V:4/3x3.14x5,929.741
V:4/3x18,619.38674
V=24,825.84898
The Volume is approximately 24,825.85
<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>
Answer:
8/5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-4-68)/(21-66)
m=-72/-45
simplify
m=8/5
88%, 44/50 is just 88/100. So 88% out of 100 of the coins are quarters.
