3.PS-15
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.
I think that there would be 20 trucks because <span>6 + 10 + 14 + 15 = 45, </span><span>6 + 10 + 14 + 15 = 45, </span><span>45 + 45 = 90 </span>
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) = 
, 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)= 
P(x = 2) =0.04661
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= 
⇒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.
