1. 2(-3) + 4
-6 + 4 = -2
2. -4^2 - 3
16 - 3 = 13
3. 2 (m + 2) + 4
2m + 4 + 4
2m + 8
2m = -8
m = -4
4. i forgot how to do this. sorry :'(
6(-2+8b)+2b -12+48b+2b 50b-12
Answer:
naurto, eddie murphy, meliodas, Kevin Hart, Craig, smokey, Jackie Chan, day day
Step-by-step explanation:
You have to find the common denominator which is 4 and multiply 26 by 4 which equals 104 add 3 which is 107 and divide by 4
Answer:107/4
<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>
