Between -0.56 and -0.65 : -0.560000000001 and -0.649999999999
Between -5.76 and -5.77 : -5.7601 and -5.7602
Between 3.64 and 3.46 : 3.639 and 3.63900001
Answer:
x>-39
Step-by-step explanation:
-4x/-4=x
-4/-4=1
1-40=-39
<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>
36x-8y^2
36(3)-8(-6)^2
108-8(36)
108-288
=-180 <----
That’s 4- 1 and 3/4. The answer is 2 and 1/4
