75 tickets X 8 = 600 ( remember you need 120 extra to pay supplies cost, so you need to sell 90 tickets and the costs is $ 8 per tickets)
let's say now.
90 tickets X 8 = 720.
720- 120= 600

A student uses the following steps to prove the sine sum identity. The proof is incorrect. Which steps is incorrect
Answer:
4
Step-by-step explanation:
The incorrect step is Step 4, cos (π/2 -x) cos(-y) + sin (π/2 -x)sin(-y), the correct option is C.
What is Trigonometric Identity?Trigonometric Identities are based on the trigonometric ratios used to solve Trigonometric equations.
The steps used to solve the trigonometric identity are :
Step 1 : sin(x+y)
Step 2: cos ((π/2) - (x+y))
Step 3 : cos ( (π/2 -x) -y)
Step 4 : cos (π/2 -x) cosy + sin (π/2 -x)siny
Step 5: sinxcosy+cosxsiny
Therefore,the correct step is cos (π/2 -x) cosy + sin (π/2 -x)siny and not cos (π/2 -x) cos(-y) + sin (π/2 -x)sin(-y) , the incorrect step is Step 4.

A submarine descends to a depth of 600 feet below the surface in 10 minutes. At this rate, what integer represents the change, in feet, of the submarine's position after one minute?
I really need help.
A submarine descends to a depth of 600 feet below the surface in 10 minutes. At this rate, what integer represents the change, in feet, of the submarine's position after one minute?
First you need to list what you're given.
A submarine descends to a depth of 600 ft below the surface in 10 minutes. The question is asking for the change of the submarine's position after one minute. This can be represented as fractions in terms of [tex]\frac{distance}{time}[/tex].
[tex]\frac{600}{10} = \frac{x}{1}[/tex]
You're looking for the value of x. First you need to cross-multiply.
[tex]600 \times 1 = 10 \times x\\600=10x[/tex]
Since you're looking for x alone, you need to divide both sides by 10. This will eliminate the 10 since x is being multiplied by 10, and 10 divided by 10 is 1, making it 1x or x.
[tex]\frac{600}{10} = \frac{10x}{10}[/tex]
[tex]60=x[/tex]
That means the submarine is descending at a rate of 60 feet per minute, which can be represented as -60.
If you're looking for the submarine's position after one minute, all you have to do is subtract 60.
600 feet below surface is represented as -600.
[tex]-600-60=-660[/tex]
The submarine's position after one minute is 660 feet below surface(-660).

Step-by-step explanation:
During the 2004 senatorial campaign in a large southwestern state, illegal immigration was a major issue. One of the candidates argued that illegal immigrants made use of educational and social services without having to pay property taxes. The other candidate pointed out that the cost of new homes in their state was 20–30% less than the national average due to the low wages received by the large number of illegal immigrants working on new home construction. A random sample of 5,500 registered voters was asked the question, "Are illegal immigrants generally a benefit or a liability to the state’s economy?" The results were as follows: 3,500 people responded "liability," 1,500 people responded "benefit," and 500 people responded "uncertain."
a. What is the population of interest?
b. What is the population from which the sample was selected?
c. Does the sample adequately represent the population?
d. If a second random sample of 5,000 registered voters was selected, would the results be nearly the same as the results obtained from the initial sample of 5,000 voters? Explain your answer.
Answer:
a
The population of interest is the registered voters , this is because it is the population from which the sample size is selected from.
b
The population is the registered voters of the large southwestern state
c
Well this does not adequately represent the population because this sample where selected from only the registered voters of the large southwestern state and not the whole country
d
Yes the result will be nearly the same because
Both samples are selected from the same population The size of the sample selected is sufficiently large to approximate the populationStep-by-step explanation:
From the question we are told that
The sample size is n = 5,500
Considering question a
What is the population of interest
The population of interest is the registered voters , this is because it is the population from which the sample size is selected from.
Considering question b
What is the population from which the sample was selected
The population is the registered voters of the large southwestern state
Considering question c
Does the sample adequately represent the population
Well this does not adequately represent the population because this sample where selected from only the registered voters of the large southwestern state and not the whole country
Considering question d

Based on experience, Farmer Fern knows that 15% of her eggs will be damaged in
route to the stores. In a sample of 100 eggs, what is the probability that less than
13% will be damaged?
Answer: 0.2877
Step-by-step explanation:
Given : The proportion of eggs will be damaged in route to the stores = 15% = 0.15
Sample size = 100
Let p be the probability of her eggs will be damaged.
The probability that less than 13% will be damaged is given by :-
[tex]P(p<0.13)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}<\dfrac{0.13-0.15}{\sqrt{\dfrac{0.15\times(1-0.15)}{100}}})[/tex]
[tex]=P(z<-0.56)[/tex]
[tex]=1-P(z<0.56)\\\\= 1-0.7123\\\\= 0.2877[/tex]
Hence, the required probability = 0.2877
