Challenge The members of the city cultural center have decided to put on a play once a night for a

week. Their auditorium holds 500 people. By selling tickets, the members would like to raise $2,350

every night to cover all expenses. Let d represent the number of adult tickets sold at $6.50. Lets

represent the number of student tickets sold at $3.50 each. If all 500 seats are filled for a

performance, how many of each type of ticket must have been sold for the members to raise exactly

$2,350? At one performance there were three times as many student tickets sold as adult tickets. If

there were 400 tickets sold at that performance, how much below the goal of $2,350 did ticket sales

fall?

The members sold

adult tickets and

student tickets.

Suppose it is known from large amounts of historical data that X, the number of cars that arrive at a specific intersection duri
Andrew [12]

Answer:

a) P(x>8) = 0.3937

b)  P(x = 2) =0.04661

Step-by-step explanation:

a) From to find the probabilty that in this specific time period, more than 8 cars arrive at the intesection, we use the probability function thus

P(x>8) = 1 - P(x≤8),  Cause you can use the complement for calculate this probability , then:

P(x≤8) = \frac{e^{-6}*6^{0} }{0!}+\frac{e^{-6}*6^{1} }{1!}+\frac{e^{-6}*6^{2} }{2!}+... , until x= 8, then you obtain:

P(x≤8)=0.6063 and

P(x>8) = 1 - P(x≤8)= 1-0.6063 = 0.3937

b) P(x=2)= \frac{e^{-6}*6^{2}  }{2!}

 P(x = 2) =0.04661

What is the point of intersection when the system of equations below is graphed on the coordinate plane?
WARRIOR [948]

Neither of the options are correct for the given equations.

Step-by-step explanation:

-x+y=4...................................................1

16x+y=-3...............................................2

Subtract equation 1 and 2

                              -x+y- 16x -y = 4+3

                               ⇒ -17x = 7

                               ⇒x= \frac{7}{-17\\}

                              ⇒x= -0.4117

so,

                        16×-0.4417 + y = -3

                       ⇒y= -3+6.5872

                      ⇒y= 3.5872

So the point of intersection is (-0.4117, 3.5872)

Answer:

136°

Step-by-step explanation:

Vertically opposite angles are always equal.

The opposite angle to x is 136°.

Both angles are vertically opposite angles, so they are equal.
