<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>
Your answer would be D.
This is because you could multiply 5/8 by 2 to get 10/16.
Answer:
Robot will take 
hour to complete each task.
The robot can complete 
tasks in one hour.
Step-by-step explanation:
We have been given that a robot can complete 8 tasks in 3/10 hour. Each task takes the same amount of time.
To find the time taken by robot to complete each task we will divide total time taken to complete 8 tasks by 8 as:
Now we will convert division problem into multiplication problem by flipping the 2nd fraction.
Therefore, robot will take hour to complete each task.
To find tasks completed by robot in one hour we will use proportions.
Therefore, the robot can complete tasks in one hour.
