I'm pretty sure the answer is A or what ever letter that says caleb experiment had 100 and jenna had 250
Answer:
Closest standard deviation of W = 4.11
Step-by-step explanation:
Randomly selected workers = n =300
Probability of workers arriving between 6:45 to 7:00 A.M = p = 6% = 0.06
According to binomial distribution:
mean = μ = n.p
= 300(0.06) = 18
variance = σ² = n.p(1-p)
= (300)(0.06)(1-0.06)
= (18)(0.94)
= 16.92
standard deviation = σ = 4.11
Answer:
$3,015
Step-by-step explanation:
To determine the amount that you will have in 6 years, you have to use the formula to calculate the future value:
FV=PV*(1+i)^n
FV= future value
PV= present value= $1,900
i= interest rate= 8%
n= number of periods of time= 6 years
FV=1,900*(1+0.08)^6
FV=1,900*(1.08)^6
FV=3,015
According to this, the answer is that in 6 years you will have $3,015 in your retirement account.
Answer:
cot²x
Step-by-step explanation:
Using the identity
sin²x + cos²x = 1, then
1 - sin²x = cos²x
1 - cos²x = sin²x
Thus
= 
= cot²x
<span>first, we are going to define variables as the following:
a = 0
a = π/2
n = 4 rectangles
Δx = [ b - a ] / n ------>Δx = [ π/2 - 0 ] / 4 = π/8
right endpoints :
sum( seq( 4 cos(x) * π/8 , x , 0+π/8 , π/2 , π/8 ) ) = 3.163065 underestimate
left endpoints:
sum( seq( 4 cos(x) * π/8 , x , 0 , π/2-(π/8) , π/8 ) ) = 4.733861 overestimate
the reason because the actual estimate by integral as the following:
π/2
∫ 4cos(x) dx = 4
