2. Kachina is going to a concert that begins at 7:30 P.M. She
needs to arrive at the ticket window 15 minutes before
the concert to get her ticket. It takes Kachina 35 minutes
to ride to the concert, then 10 minutes to park the car. At
what time should Kachina leave for the concert?
Answer:
6:30 P.M.
Step-by-step explanation:
Since Kachina must do all these things before 7:30 P.M., we must find the sum of the times of the things she must do before the concert and subtract it from 7:30
The sum of the minutes is 60, which is 1 hour. Thus, Kachina should leave 1 hour before 7:30 which is 6:30 P.M.

Step-by-step explanation:
Remark
You have to assume that O is the center of the circle. Two sectors are marked as equal, so equate them to find x
Equation and Solution
5x + 5 = 4x - 20 Subtract 5 from both sides
5x + 5 - 5 = 4x+ 20 - 5 Combine
5x = 4x + 15 Subtract 4x from both sides.
5x-4x = 4x-4x + 15
x = 15
TOU = 5*15 + 5 = 80
VOW = 80 TOU and VOW are marked as equal
UOV = 6x -20 = 70
Total of all three = 80 + 80 + 70 = 230

If 2 L of water is mixed with 4.5 L of milk and filled into 650 mL cans. Then
cans will be needed to fill the mixture.
The numbers of can required to fill the mixture is 10 cans
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.

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?
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
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]

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?

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.
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.

The graph below represents the relationship between the number of days a book is overdue and the library fine charged. A graph titled Library Fines. The horizontal axis shows days overdue and the vertical axis shows the fine (dollars). The line shows an increase to $10 at 19 days overdue, then constant. Christen returned an overdue book to the library. Her fine was the same as it would have been if she returned the book the previous day. Which of the answer choices below could be the number of days Christen’s book is overdue? 10 14 18 22
The number of days Christen's book is overdue could be 22 according to options given.
The graph which represents the relationship between the number of days a book is overdue and the library fine charged is attached below :
According to the graph, a constant relationship exists between the number of days a book is overdue and the library fine charged when the Number of days book is overdue is about 19 days and above such that the library fine charged stays the same at $10.
Since we are told that Christen's fine for returning the book is the same as the fine she would have paid if book was returned yesterday, then, the number of days Christen's book is overdue could be 20 days and above.
The only value above 20 from the options given is 22.

A doctor wants to research if there is any difference in the birth weights of a mother's first child and second child. Suppose that data were collected for a random sample of 10 mothers with 2 children, where each difference is calculated by subtracting the weight of the first child from the weight of the second child. Assume that the weights are normally distributed. The doctor uses the alternative hypothesis Ha:μd≠0. Suppose the test statistic t is calculated as −1.101, which has 9 degrees of freedom. If the p-value is greater than 0.10 and the significance level is α=0.10, what conclusion can be made about the birth weights of a mother's first 2 children?
Answer:
There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance.
Step-by-step explanation:
When our p-value exceeds level of significance then we fail to reject our null hypothesis. In this scenario we are investigating if there exists significant difference in the birth weights of a mother's first child and second child and our null hypothesis is there exists no significant difference in the birth weights of a mother's first child and second child i.e.μd=0.
As we are given that p-value is greater than 10% level of significant so, we cannot reject our null hypothesis. Thus, the conclusion statement can be written as "There is not sufficient evidence to conclude that there exists significant difference in the birth weights of a mother's first child and second child at 10% level of significance."
