Answer:
P = 14 * 22.5/5 = 63
Step-by-step explanation:
Step1. Find perimeter of small triangle
Step2. Find the ratio between 2 triangles
Step3. Multiply
MP3 players in the shipment which are likely to be defective is 330.
Step-by-step explanation:
• Probability is event of an occurrence which is uncertain.
• Probability always lies between 0 to 1.
• The sample of 50 MP3 has 6 defective, to solve it has to be converted.
• Convert percentage in 100 multiply numerator and denominator by 2.
• Result is 6/50 converted to 12/100, bring it to 0.12%.
• 12% is defected in 100% of sample.
• It is found here that 2750 is the population and 12% of 2750.
• 2750 * 0.12 = 330, defective pieces in 2750.
• There are three types of Classical,Empirical or Experimental.
• Classical are ‘n’ number of events find the probability occurrence.
• Empirical or experimental is purely based on events.
Step-by-step explanation:
Let x be the amount of tickets sold for $25 and y be the amount of tickets sold for $40, since there are 6000 seats theatre then;
x+y = 6000 .............. 1
If x tickets cost $25 and y tickets are sold for $40 with total revenue of $174,000, then;
25x + 40y = 174,000................ 2
From 1, x = 6000-y ............ 3
Substitute equation 3 into 2:
25x + 40y = 174,000.
25(6000-y) + 40y = 174,000
150,000-25y + 40y = 174,000
150,000+15y = 174,000
15y = 174,000-150,000
15y = 24,000
y = 24,000/15
y = 1600
Substitute y = 1600 into equation 3:
x = 6000-y
x = 6000-1600
x = 4400
<em>Hence 4400 $25 tickets and 1600 $40 tickets must be sold to generate a revenue of $174,000</em>
Answer:
The first question would likely be y=10.
The second question would likely be x=20.
so if x = -1, let's plug that in the second equation
-5(-1)+y = 5
5+y = 5
y = 0
