<h3>Speed of light:</h3>
<h3 /><h3>Seconds in a year:</h3>
Multiply the speed of light with seconds in a year
*Note:- We will not change the values because speed of light is in m/s and the time is also given in seconds.
<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>
15-13 = 2
2+15 = 17
so 17 is your answer
Answer: C. 18 2/3cm
Explanation:
Area of rectangle = length x width
After you set up the fractions:
96/30 x 175/30
= 16800/900
= 18.666e
= 18 2/3
