Answer:
The balcony seat costs $9, the orchestra seat costs $9 + $6 = $15.
Step-by-step explanation:
Let x is the cost/price of one balcony seat, in dollars.
Then the cost of one orchestra seat is (x+6) dollars, according to the condtion.
The total cost of tickets is
250x + 400*(x+6) = 8250.
Simplify it step by step.
250x + 400x + 2400 = 8250,
650x = 8250 - 2400 = 5850 ====> x = 5850/650 = 9.
Answer. The balcony seat costs $9, the orchestra seat costs $9 + $6 = $15.
Check. 9*250 + 15*400 = 8250. Correct.
Answer:
The standard deviation of the number of defective bulbs produced in an hour is 6.615
Step-by-step explanation:
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
In this problem, we have that:
What is the standard deviation of the number of defective bulbs produced in an hour
The standard deviation of the number of defective bulbs produced in an hour is 6.615
Answer: example, if both sides of the inequality are multiplied by a negative number, say -3, we get (-2) x (-3) < 7 x (-3) 6 < -21 When both sides of the inequality are multiplied by a negative number, the resulting inequality is not true. To make the resulting inequality true, we have to reverse the inequality symbol.
