Answer:

So we have at least 88.89% of the noise level values within 3 deviation from the mean.
Step-by-step explanation:
For this case let define the random variable X as the noise level, we know the following properties for X:

And for this case we don't know the distribution for the random variable X.
But we can use the Chebysev theorem who states that the minimum percentage of the data that lies within k standard deviations from the mean is given by:

So for this case we have that k = 3 and if we use this theorem we have:


And we can convert this into % and we got:

So we have at least 88.89% of the noise level values within 3 deviation from the mean.
Answer:
I THINK is (57°) if it wrong im sorry.
Answer:
$35.79. I hope this help!!
Step-by-step explanation:
First, we can determine the amount of the tax:
t
=
b
⋅
r
Where:
t
is the amount of the tax.
b
is the amount of the bill - $28.35 for this problem.
r
is the tax rate.
6.25
%
for this problem. Percent or % means per 100 or out of 100. We can write
6.25
%
as
6.25
100
Substituting gives:
t
=
$
28.35
⋅
6.25
100
t
=
$
177.1875
100
t
=
$
1.771875
t
=
$
1.77
Next, we can determine the amount of the tip:
p
=
b
⋅
g
Where:
p
is the amount of the tip.
b
is the amount of the bill - $28.35 for this problem.
g
is the gratuity rate.
20
%
for this problem. Percent or % means per 100 or out of 100. We can write
20
%
as
20
100
Substituting gives:
p
=
$
28.35
⋅
20
100
p
=
$
567.00
100
p
=
$
5.67
Now, we can add the amount of the bill, the tax and tip amounts to find the total cost:
$28.35 + $1.77 + 5.67=$35.79
