Answer:
Mean = 3.4
Variance = 1.088
Standard deviation = 1.0431
Step-by-step explanation:
The mean of a binomial distribution with parameters N (the number of trials) and p (the probability of success for each trial) is 
Thus,
The variance of the binomial distribution is 
, where 
is the variance of the binomial distribution, so
The standard deviation 
is the square root of the variance 
so
9514 1404 393
Answer:
1,570,000
Step-by-step explanation:
The sum is approximately ...
1,260,000 +310,000 = 1,570,000

<em>Additional comment</em>
It is a good idea to estimate the error associated with an estimate. Here, both numbers are rounded up by about 4000 each, so the estimate is around 8000 high.
<span>Round 0.30 each (or $1.80 for all 6 of them), the milk is
$1.30. Total of estimates is $11.10
The customer gave you 5 + 6 + 0.25 or $11.25, which is very close
(and slightly higher) than the total of your estimates. I'd guess the
register is correct.
Actual value is $8.04 + 6*0.29 + 1.31 = 8.04 + 1.74 + 1.31 = $11.09. The register is definitely correct. </span>
The equation for the slope intercept form is 2,3
Answer:
A 3.14159.......
Step-by-step explanation:
We need a non rational number
3.14159 is pi which is an irrational number
1/7, .27(repeating) and .83333(repeating) can be written in the form
a/b where a and b are integers, which makes them rational
