Answer:
(a)P(x>85.55)=0.02275
(b)
Step-by-step explanation:
We are given that
Average sales for an online textbook distributor per customer per purchase
,
$67.63
Standard deviation of the amount spent on textbooks,
$8.96
(a) We have to find probability for a randomly selected customer spent more than $85.55 per purchase.
=
=
=
P(x>85.55)=0.02275
(b)We have to find probability for a randomly selected customer spent less than $76.59 per purchase
<span>Diameter :D , Raduis : R
D = 2R
R = 1.4 angstrom
1 angstrom = 0.00000001 cm = 10^-7
cm
R = 1.4 * 10^-7 cm
D = 2.8 * 10^-7 cm</span>
The answer is D

Y would equal 0. 2x2=4 and 4-4=0.
A rational number is a number that can be expressed as the relationship between two integers. Fractions and decimals will either repeat or end. An example is 5. Maybe 7. 53573 is an example as well. So is 5/1, because 5 and 1 are both integers. so is 7.5, because 7 and 5 are both integers, and it ends (the numbers after the decimal doesn't keep going). Your answer is 7.8, because it ends.
