Answer:
277.46
Step-by-step explanation:
Many large cities use taxes on entertainment tickets to pay for improvements to public facilities, like stadiums, arenas, and concert venues. A city council proposal would increase the current ticket tax in order to raise funds for a new public concert hall. Council representatives plan to conduct a survey outside of a large concert in the summer and ask selected adults if they would support an increase in the ticket tax to pay for the new concert hall. Which type of bias will most likely affect the survey results? This is response bias because it is likely that many who respond will not provide a truthful opinion of the ticket tax. This is undercoverage bias because only those attending the concert will have an opportunity to register an opinion. This is nonresponse bias because many who are asked about the ticket tax may choose to not provide a response. This is voluntary response bias because many vocal supporters of the ticket tax may demand to register their opinion.
Answer:
This is undercoverage bias because only those attending the concert will have an opportunity to register an opinion.
Step-by-step explanation:
Undercoverage bias occurs when the sample chosen for a research is not representative of the entire population. Most times when research involving surveys to obtain the opinions of people on a subject matter, the entire population affected by the issue cannot be surveyed. A sample that represents the true population can be used for this research.
In the survey above, the sample that was surveyed was not representative of the entire population of citizens paying taxes on entertainment tickets. The selection process does not represent the true population.

If x increases by 7 in each row of a table of values, and the first differences are all equal to 45.5, then the rate of change is:
a) 6.5
b) 455/7
c) 7/455
d) 318.5
Answer:
b i think
Step-by-step explanation: dont yell just tell me if i got it wrong if i did srry
The rate of change when x increases and the first difference equal to 45.5 is 6.5. Then the correct option is A.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope is given as
[tex]\rm Slope = \dfrac{Rise \ or \ fall}{Run}[/tex]
If x increases by 7 in each row of a table of values and the first differences are all equal to 45.5. Then the rate of change will be given by the slope.
[tex]\rm \\Slope = \dfrac{45.5}{7} = 6.5[/tex]
The rate of change is 6.5.

May someone help me out with these problems? Please explain
Answer:
Well you have to solve each problem first to make them the same. Let's do decimals.
a) The square root of 58 is 7.61577310586. Let's round that to 7.62. You can solve this with a calculator.
b) Simply -32.0, since it is a whole negative number.
c) I think there's a typo, 'C' is the second 'b)', which is 49/7. 49 divided by 7 is seven, hence the decimal would be 7.0
d) 2.65 repeated, already a decimal, does not need changed.
e) The square root of 6 is 2.44948974278. Let's round that to 2.45.
f) is just 0. no decimal, just 0.
Now that you have these as the same form of number, you have to put them into one of these categories. The categories can be found below.
Any square root number is irrational. Any never ending number is irrational, like pi, but there are none of those in this situation. So a, and e are all irrational.
Any repeated number, in this case, 2.65 repeated, is a rational number, as is any decimal or fraction, but there are none of these, so d is rational.
-32 is and integer, because it is a negative whole number, so b is an integer.
Whole numbers are any numbers 0+. So f is the only answer that is a whole number.
Natural numbers are any numbers 1+. So c or the second b is a natural number.
Hope this helps :)

Delaney is saving money in an account that offers 9% simple interest. She deposits 2000 from her grandmother into the account and makes no additional deposits or withdraws. How many years will it take to grow to 4,700
Answer:
15years
Step-by-step explanation:
Given data
Rate= 9%
Principal= $2000
Final amount= $4700
The simple interest formula is given as
A= P(1+rt)
Substitute
4700=2000(1+0.09*t)
4700= 2000+ 180t
4700-2000= 180t
2700=180t
t= 2700/180
t= 15 years
Hence the time is 15years

marty has 1 1/3 jugs of apple juice. he uses 3/4 of the juice to make freeze pops. what fraction amount of a jus doe marty have?
Answer:
He has 1/3 of a jug left.
Step-by-step explanation:
He starts with 1 1/3 jugs.
He uses 3/4 of 1 1/3 jugs.
A full amount is 1 or 4/4. If he uses 3/4, he has 1/4 left since
1 - 3/4 = 4/4 - 3/4 = 1/4
That means he has 1/4 of 1 1/3 jugs left.
We need to multiply 1/4 by 1 1/3.
1/4 * 1 1/3 =
= 1/4 * 4/3
= 4/12
= 1/3
Answer: He has 1/3 of a jug left.

Dakota earned $11.25 in interest in Account A and $25.00 in interest in Account B after 15 months. If the simple interest rate is 3% for Account A and 5% for Account B, which account has the greater principal? Explain.
Which account has the greater principal? Select the correct answer below and fill in the answer boxes to complete your choice.
Answer:
Step-by-step explanation:
I=Prt
11.25=A(0.03)(15/12)
11.25=A(0.0375)
A=11.25/(0.0375)
A=$300
25=B(0.05)(15/12)
25=B(0.0625)
B=25/(0.0625)
B=$400
So account B has the greater principal.

The cost c in dollars of manufacturing x bicycles at a production plant is given by th function shown below C(x)=5x^2-1000x+63,500. How many bicycles must be manufactured to minimize the cost
Answer:
100 bicycle
Step-by-step explanation:
Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.
x is the number of bikes
To minimize the cost, dC/dx = 0
dC/dx = 10x - 1000
Since dC/dx = 0
0 = 10x - 1000
-10x = -1000
x = 1000/10
x = 100
Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

Sue has 4lbs 6oz of apples. Her younger brothers ate some and now she has 2lbs and 10oz how many lbs and oz of apples did they eat
Answer: 1 lbs 12 oz
Step-by-step explanation:
First and foremost, we should note that 16 ounces = 1 pound
Sue has 4lbs 6oz of apples. This in ounces will be:
= (4 × 16) + 6
= 64 + 6
= 70 ounces
Her younger brothers ate some and now she has 2lbs and 10oz. The ounces of apples left will be:
= (2 × 16) + 10
= 32 + 10
= 42 ounces
Therefore, the amount they ate will be:
= 70 ounces - 42 ounces
= 28 ounces
Since 16 ounces = 1 pounds
= 1 pounds 12 ounces
= 1 lbs 12 oz
For volunteers picked up letter from the park Dominic you collect and 15 for your pieces a litter than Sarah Sarah collect the 12 more pieces in piper piper collected 1/4 as many pieces of litter as Vaughn Vaughn has collected nine more pieces of wood or than everyone else combine the X represent the number of pieces of litter Vaughn Collection
So many confusing details. So, I rephrase the question as:
Four volunteers picked up litters from the park.
Dominic collect 15 pieces less than Sarah. Sarah collects 12 more pieces than Piper. Piper collected 1/4 as many pieces of letter as Vaughn. Vaughn has collected nine more pieces of letter than everyone else combined. Let x represent the number of pieces of litter in Vaughn's Collection. Find x
Answer:
[tex]x = 72[/tex]
Step-by-step explanation:
Let:
[tex]D = Dominic;\ \ S = Sarah;\ \ P = Piper;\ \ V = Vaughn[/tex]
From the [rephrased] question, we have:
[tex]D = S - 15[/tex]
[tex]S = 12 + P[/tex]
[tex]P = \frac{1}{4}V[/tex]
[tex]V = 9 + D + S + P[/tex]
Substitute [tex]S = 12 + P[/tex] in [tex]D = S - 15[/tex]
[tex]D = 12 + P - 15[/tex]
[tex]D = P+12 - 15[/tex]
[tex]D = P-3[/tex]
Make V the subject in [tex]P = \frac{1}{4}V[/tex]
[tex]V = 4P[/tex]
Substitute: [tex]V = 4P[/tex], [tex]D = P-3[/tex] and [tex]S = 12 + P[/tex] in [tex]V = 9 + D + S + P[/tex]
[tex]4P= 9 + P - 3 + 12 + P +P[/tex]
Collect like terms
[tex]4P - P -P-P= 9 - 3 + 12[/tex]
[tex]P= 18[/tex]
Substitute [tex]P= 18[/tex] in [tex]S = 12 + P[/tex]
[tex]S = 12 +18[/tex]
[tex]S = 30[/tex]
Substitute [tex]S = 30[/tex] in [tex]D = S - 15[/tex]
[tex]D = 30 - 15[/tex]
[tex]D =15[/tex]
Substitute [tex]D =15[/tex], [tex]S = 30[/tex] and [tex]P= 18[/tex] in [tex]V = 9 + D + S + P[/tex]
[tex]V = 9 + 15 + 30 + 18[/tex]
[tex]V = 72[/tex]
x represents the number collected by Vaughan.
So:
[tex]x = 72[/tex]
