Answer:
5.66
Step-by-step explanation:
40% off means you are paying 60% of the original price ( 100% - 40% = 60%
Multiply the price of the coat by 60%:
65.00 x 0.60 = 39.00 ( sale price)
Now multiply the sale price by 1.05 ( price of coat plus tax rate) to get the final cost:
39.00 x 1.05 = 40.95
The final price is $40.95
Mean number of errors in each page = 0.01
Mean number of errors in 100 pages = 0.01*100=1
It is possible to use the cumulative distribution function (CMF), but the math is a little more complex, involving the gamma-function. Tables and software are available for that purpose.
Thus it is easier to evaluate with a calculator for the individual cases of k=0,1,2 and 3.
The Poisson distribution has a PMF (probability mass function)


with λ = 1

or
P(k<=3)=
0.9810 (to four decimal places)
Answer:
16
Step-by-step explanation:
Using the rule of exponents/ radicals
=
, then
=
, then
= 8 ( cube both sides )
n² = 8³ ( take the square root of both sides )
n = 
= 
= 
=
× 
= 16
