Answer:
The minimum sample size that we should consider is of 60 employees.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find the margin of error M as such
In which 
is the standard deviation of the population and n is the size of the sample.
We want our 99 percent confidence interval to have a margin of error of no more than plus or minus 2 minutes. What is the smallest sample size that we should consider?
We need to find n for which 
So
Simplifying by 2
Rounding up
The minimum sample size that we should consider is of 60 employees.
Answer: There 64 possible sequences in which team A wins
Step-by-step explanation:
Hi!
The sequences in which team A wins, are the ones with at least 4 A's.
Sequences with 4, 5, 6 or 7 A's. To calculate how many of each type exist, we use the formula of combinations. If you select K objects from a set of N objects, there are C(N, K) possibilities, give by the formula:
Then the total M number of sequences in which team A wins is:
Product = sum of multiplication
If you expand the polynomial using the FOIL method you get the answer of:
-81r^2 + 16
Answer:
k= 4 19/24
Step-by-step explanation:
Answer:
$18,089.96
Step-by-step explanation:
Given:
Worth of car = $25077
down payment = $3560
month end car payments = $336
Time period = 5 years
Interest rate, i = 4.04% compounded semi-annually
since, the interest is compounded semi-annually thus, the actual time period, n will be 5 × 2 = 10 fro semi annually
Total payment made semi annually, A = $336 × 6 = $2016
Now,
or
or
Thus,
The value of car loan payment is $18,089.96
