Blaine is selling tickets to a rock concert. Tickets in the front section cost $60 each. Tickets in the back section cost $40
each. Blaine has 55 tickets left to sell, and to meet his sales quota he needs to sell more than $600 in tickets from the
remaining tickets.
Blaine makes a profit of $40 on every ticket for the front section. He makes a profit of $25 on every ticket for the back
section. What's the maximum profit Blaine can make from selling his remaining tickets?
You may find it helpful to review the steps of linear programming e.

Write the system of inequalities for the given situation where x represents the number of front section tickets and y
represents the number of back section tickets.
Answers
Answer:
25 tickets more
Step-by-step explanation:
I got x+y is (less than or equal to) 55 for the first inequality and 60x+40y>600 for the second one!
Step-by-step explanation:
Since Blaine can sell a maximum of 55 tickets, the first inequalitly is x+y is less than OR EQUAL TO 55. Since the tickets in the back section cost $40 each, 40y represents the money made from those tickets. Blaine needs to make 600 in sale so the inequality is 60x+40y>600.

[tex]\sf y = \dfrac{17}{2}[/tex]
explanation:
[tex]\sf 7y-4=9y+13-4y[/tex]
collect variables in one side
[tex]\sf 7y -9y +4y = 13 +4[/tex]
simplify by addition and subtraction
[tex]\sf 2y = 17[/tex]
divide both sides by 2
Hence, ,final answer:
[tex]\sf y = \dfrac{17}{2}[/tex]
Answer:
A. y = 17/2
Step-by-step explanation:
Given equation:
7y - 4 = 9y + 13 - 4y
Collect like terms:
7y - 4 = 9y - 4y + 13
Combine like terms:
7y - 4 = 5y + 13
Subtract 5y from both sides:
2y - 4 = 13
Add 4 to both sides:
2y = 17
Divide both sides by 2:
y = 17/2
The same sequence may be defined in three ways: 1) f(x) = 3x + 4 for x = {1, 2, 3, ...}, 2) a1 = 4 and an + 1 = an + 3 for n = {1, 2, 3, ...} and 3) an = 4 + 3(n − 1) for n = {1, 2, 3, ...}.
They are all supposed to generate the same values, but one version may contain an error. If one version contains an error, identify the one with the error and fix it.

Answer:
There probably isn't a mode.
Step-by-step explanation:
Because the numbers in this set of data are continuous, it is impossible to have a mode, the number that occurs most frequently in a set of data.
Answer:
[1] Not enough information to draw valid conclusion
[2] The mean will be 12.
[3] 14
[4] 5 and 7
Step-by-step explanation:
[1] if the range for a set of data is 24, from 2 to 26 and the mean is 17, what can you conclude about the data
17 is the typical data value.
Not enough information to draw valid conclusion.
The median will be 17 also.
There probably isn't a mode.
Answer: Not enough information to draw valid conclusion.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[2] The extreme values in a set of data are 5 and 19. What is true about the data set?
The mean will be 12.
There is not enough data.
The range is 14.
There will be more than one mode.
Answer = The mean will be 12.
Explanation : Mean = add all values and divide by the number of values. 5+19=24, 24/2=12
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[3] What is the mean for the following set of data, to the nearest whole number?
5,9,15,18,22
Answer = 14
Explanation:
5 + 9 + 15 + 18 + 22 = 69
69 / 5 = 13.8
Round 13.8 = 14

5.16 Identify hypotheses, Part II: Write the null and alternative hypotheses in words and then symbols for each of the following situations. (a) Since 2008, chain restaurants in California have been required to display calorie counts of each menu item. Prior to menus displaying calorie counts, the average calorie intake of diners at a restaurant was 1100 calories. After calorie counts started to be displayed on menus, a nutritionist collected data on the number of calories consumed at this restaurant from a random sample of diners. Do these data provide convincing evidence of a difference in the average calorie intake of a diners at this restaurant?
Answers
Answer:
H₀: µ = 1100 vs. Hₐ: µ ≠ 1100.
Step-by-step explanation:
A null hypothesis is a sort of hypothesis used in statistics that intends that no statistical significance exists in a set of given observations.
It is a hypothesis of no difference.
It is typically the hypothesis a scientist or experimenter will attempt to refute or discard. It is denoted by H₀.
For instance, H₀: µ = µ₀, where µ₀ is some null value or some claimed value.
Whereas, the alternate hypothesis is the contradicting statement to the null hypothesis.
The alternate hypothesis describes direction of the hypothesis test, i.e. if the test is left tailed, right tailed or two tailed.
It is also known as the research hypothesis and is denoted by Hₐ.
In this case the hypothesis can be defined as follows:
Null hypothesis:
H₀: The average calorie intake of a diner at this restaurant is 1100, i.e. µ = 1100.
Alternate hypothesis:
Hₐ: The average calorie intake of a diner at this restaurant is different from 1100, i.e. µ ≠ 1100.
How many whale sharks would a researcher need to measure so that 90% confidence level would have a margin of error of 0.25
Answers
About 1407 sharks would be needed to have a margin of error of 0.25
What is margin of error?
Margin of error is used to determine by what value there is deviation from the real value. Margin of error (E) is given by:
[tex]E=Z_\frac{\alpha}{2} *\frac{standard\ deviation}{\sqrt{sample\ size} }[/tex]
The 90% confidence level have a z score of 1.645. Hence for E = 0.25, standard deviation = 5.7 feet, hence:
[tex]0.25=1.645*\frac{5.7}{\sqrt{sample\ size}}\\ \\sample\ size=1407[/tex]

Data;
Volume of water = 2Lvolume of milk = 4.5Lvolume of cans = 650mL = 0.65LNumber of Cans Required to fill the mixtureTo find the numbers of can required to fill the mixture, let's add the volume of the mixture.
volume of mixture = volume of water + volume of milk
volume of mixture = [tex]2 + 4.5 = 6.5L[/tex]
The entire volume of the mixture is 6.5L.
To find the numbers of cans that'll fill the mixture, let us divide 6.5 by 0.65.
Number of can required = [tex]\frac{6.5}{0.65} = 10[/tex]
From the calculation above, we would need 10 cans to fill the mixture.

The correlation coefficient measures the relationship between the two variables
The correlation coefficient is 0.234
How to determine the correlation coefficientThe formula of correlation coefficient is:
[tex]r = \frac{1}{n - 1} * \sum{(\frac{x - \bar x}{\sigma_x})*(\frac{y - \bar y}{\sigma_y})[/tex]
Using the dataset from the complete question, we have:
[tex]r = \frac{1}{5 - 1} * 0.9375[/tex]
Evaluate the difference
[tex]r = \frac{1}{4} * 0.9375[/tex]
Evaluate the quotient
[tex]r = 0.234375[/tex]
Approximate
[tex]r = 0.234[/tex]
