A raffle is going to be held in which the winner will get $200. If 1000 tickets are to be sold, what is the fair
price for a ticket?
Answer:
$5
Step-by-step explanation:
1000/200=5
Answer:
20 cents.
Step-by-step explanation:
A fair price would be 200/1000 = 1/5 of a dollar which is 20 cents. But this does not allow for the people putting on the raffle to make any money for doing it. It would be better if the raffle went for a dollar. Most people would think that is fair and would not begrudge a dollar.
Have an amazing day :)

Answer:
C. As the Test Score increases, the Social media time decreases
Step-by-step explanation:
D. Yes, linear because if I were to draw a line on the graph most of the points on the scatter plots would match?
Answer:
C. As the Social media time increases, the Test score decreases.
D. Yes, I think the relationship between the test scores and social media time appears liner, because linear lines tend to be straight, and has a constant rate of change. In this case, there is a constant rate of change, and the plot points aren't all over the place.
Explanation (sort of):
Look at the graph going from left to right; You will see that the plot points continue to "fall" closer to the x-axis. This is why "Test scores" are decreasing instead of "Social media time", unlike what someone else answered with.
A box contains 17 transistors, 5 of which are defective. If are selected at random, find the probability of the statements below.
Answer:
27% chance that the transistor is defective
5:17
Step-by-step explanation:
The probability that the picked up transistor is defective is 5/17
What is a expression? What is a mathematical equation? What is Probability?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. The formula to calculate the probability of occurrence of an event 'A' can be written as -
P(A) = n(A)/n(S)
where -
n(A) = Number of outcomes favorable to event A.
n(S) = Total number of outcomes
Given is that a box contains 17 transistors, 5 of which are defective.
Probability that the picked up transistor is defective is -
P(D) = 5/17
Therefore, the probability that the picked up transistor is defective is 5/17

Answer:
x=37
Step-by-step explanation:
As you can see in the image, both angles are congruent to each other. 74 degrees and 2x degrees. You have to divide 74 by 2 to find what x equals.
74/2=37
x=37
evaluate -3 x +2x-1 if x=-5

Answer:
1/sec x- tan x
Step-by-step explanation:
sec x+ tan x
= sec x+ tan x) (sec x - tan x)/(sec x , tan x)
=sec^2x-tan^2x)(sec x- tan x)
(sec^2x-tan^2x=1)
=1/sec x- tan x
5. Examine the expression below. Select the answer that correctly completes each statement below. * Enter your answer for all parts below.
Sample Answer: C, B, C
5x+2y+7
a The term 5x could be read as:
A the sum of 5 and x
B. the product of 5 and x
C. the quotient of 5 and x
b. In the expression, 7 is a:
A coefficient
B. constant
C. variable
c. In the expression, 2 is a:
A coefficient
B. constant
C. variable
Answer:
B, B, A.
Step-by-step explanation:
5x means 5 multiplied by x, so is it A, B or C? the product, because that means multiplied. a is B.
For b, we can see that 7 is a constant, because it isn't being multiplied by anything.
For c, 2y is 2 multiplied by y. Y would be the variable, and 2 would be the coefficient.

The members of the city cultural center have decided to put on a play once a night for a week. Their auditorium holds people. By selling tickets, the members would like to raise $ every night to cover all expenses. Let d represent the number of adult tickets sold at $. Let s represent the number of student tickets sold at $ each. If all seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $? At one performance there were times as many student tickets sold as adult tickets. If there were tickets sold at that performance, how much below the goal of $ did ticket sales fall?
Answer:
a) At $3,300 for 600 seats, the average price per seat is 3300/600 = $5.50. The mix of tickets that results in that average can be found using an X diagram as shown below. The numbers on the right are the differences along the diagonals. When they are multiplied by 2, they add to 600. This shows that the required sales for revenue of $3,300 are
200 adult tickets
400 student tickets
b) When 3 student tickets are sold for each adult ticket, the average seat price is
(3*$4.50 +7.50)/4 = $5.25
Then the shortfall in revenue is ...
$3,300 -480*$5.25 = $780
