Let <em>X</em> be a random number selected from the interval. Then the probability density for the random variable <em>X</em> is
8 and 10 are the only even integers that fit the given criterion (6 is more than 0.25 away from 6.35), so that we're looking to compute
P(|<em>X</em> - 8| < 0.25) + P(|<em>X</em> - 10| < 0.25)
… = P(7.75 < <em>X</em> < 8.25) + P(9.75 < <em>X</em> < 10.25)
… = P(7.75 < <em>X</em> < 8.25) + P(9.75 < <em>X</em> < 10)
(since P(<em>X</em> > 10) = 0)
… = 0.2740 (8.25 - 7.75) + 0.2740 (10 - 9.75)
… = 0.2055
Step-by-step explanation:
Since we have given that
Number of green tickets =3
Number of yellow tickets = 4
Number of purple tickets = 3
Total number of tickets = 3+4+3=10
Now,
As we know that Pedro select a ticket and replace it and then select another ticket , total number of outcomes will never change it will be 10 only for each case.
Probability that he chooses a yellow ticket and then a purple ticket is given by
Tigers are the largest of the big cat family and the largest species can reach over 3 metres (11 feet) in length! They come from South and East Asia. Tigers are one of only two species of big cat to swim, and they often spend their days in rivers and lakes in order to keep cool. They do most of their hunting at night.
Answer:
The average cost of each tie is $56.350
Step-by-step explanation:
We are given that a men tie buyer plans to promote a $39.99 tie. Consequently, the buyer purchases 450 ties
So, Cost of 450 ties = 
An order for 100 ties that cost $20.00 each
Cost of 100 ties = 
Total cost price = 17995.5+2000 = 19995.5
Let the selling price of 1 tie be x
Total ties = 450+100 = 550
So, SP of 550 ties =550x
Now we are given that markup is 55%
So, Profit % = 55%
So, 
Substitute the values
Hence The average cost of each tie is $56.350
