Answer:
The probability that there are 8 occurrences in ten minutes is
option B. 0 .0771
Step-by-step explanation:
Given:
Random Variable = x
Mean number of occurrences in ten minutes is 5.3.
The probability of an occurrence is the same in any two time periods of an equal length
To Find:
The probability that there are 8 occurrences in ten minutes = ?
Solution:
Let X be the number of occurrences of the event X
Possion of distribution is given by ,
Substituting the values,
P(X=8) = 0.0771
Answer:
cos 30 + sin60 + sin30 - cos60
we know that sin ( 90 -a ) = cos a { and vice versa }
therefore by using this property,
sin ( 90 - 30 ) + sin 60 + sin 30 - sin ( 90-60)
sin 60 + sin 60 + sin 30 - sin 30 =
<u>2 sin 6</u><u>0</u>
That's the answer I got. Tell me if it's correct

Answer:
The commission rate in percentage = 16%
Step-by-step explanation:
Given
Commission Amount = $352
Sales Price = $2200
To determine
Find the commission rate in percentage.
Using the formula
Commission percentage = Commission Amount / Sales Price
substituting Commission Amount = 352 and Sales Price = 2200
= 352 / 2200
= 0.16
Multiply by 100 to get the percentage:
0.16 × 100 = 16%
Therefore, the commission rate in percentage = 16%
