Answer:
Step-by-step explanation:
<u>Use cosine:</u>
- cos = adjacent / hypotenuse
- cos ∠L = KL/JL
- cos 21° = 4/x
- x = 4 / cos 21°
- x = 4.3 (rounded)
Answer: 18- Hope this helps :)
(re-do with explanation)
Step-by-step explanation: The volume formula for a triangular prism is (height x base x length) / 2
All you must do is calculate it which is 4 x 3 x 3 = 36 and than you divide it by half and you get your answer- 18
New price = <u>90 dollars</u>
<u></u>
25% of 120 = 30
Price is reduced 25% from 120 so,
120 - 30 = 90
Amount of discount = 30
<span>All you have to do is learn Chebyshev's theorem in terms of k, then
substitute 2 for k.
Here is Chebyshev's theorem in terms of k:
According to Chebyshev's theorem, the proportion of values
from a data set that is further than standard deviations
from the mean is at most .
Then when you plug in 2 for k, you get:
According to Chebyshev's theorem, the proportion of values
from a data set that is further than standard deviations
from the mean is at most .
or writing for ,
According to Chebyshev's theorem, the proportion of values
from a data set that is further than standard deviations
from the mean is at most .
Or if you prefer a decimal answer:
According to Chebyshev's theorem, the proportion of values
from a data set that is further than standard deviations
from the mean is at most .
Or if you prefer a percent answer:
According to Chebyshev's theorem, the proportion of values
from a data set that is further than standard deviations
from the mean is at most %.

Answer:
A=41
B=20
C=8
D=3
Step-by-step explanation:
You need to first of all fill the intersection (yellow region). This is the number of people who use both.
This means B=20
Region A is those who use F only. So you must subtract the number who use both.
This means that A=61-20=41
Region C is those who use G+ only.
This means C=28-20=8
Now A+B+C+D=72
This implies that:
41+20+8+D=72
69+D=72
D=72-69
D=3
