A football club sells, on average, 23000 tickets per match. In one season they play, on average, 46 matches.How many tickets do they sell, on average, each season?
Answers
Answer:
the football team sells 805,000 tickets each season
Step-by-step explanation:
average number of tickets sold per match=23,000
the average number of games played each session=35
the number of tickets sold on average each session = 23,000 x 35 which equals 805,000
so the average football club sells 805,000 tickets each season

TThe Education Trust publishes data on U.S. colleges and universities. Six-year graduation rates and student-related expenditures per full-time student for 2007 were reported for the seven primarily undergraduate public universities in California with enrollments between 10,000 and 20,000. Suppose that a 90% confidence interval for the prediction of student expenditures at a university with a graduation rate of 40% was (5,304, 8,686).
Required:
a. Determine the point estimate for the prediction of student expenditures at a university with a graduation rate of 40%.
b. Calculate the margin of error.
c. Calculate the standard error of the prediction of student expenditures at a university with a graduation rate of 40%.
Answers
Answer:
a) The point estimate is 6995.
b) The margin of error is of 1691.
c) The standard error is of 1000
Step-by-step explanation:
a. Determine the point estimate for the prediction of student expenditures at a university with a graduation rate of 40%.
The point estimate is the mean of the two bounds of the confidence interval. So
\(P = \frac{5304 + 8686}{2} = 6955\)
The point estimate is 6995.
b. Calculate the margin of error.
The margin of error is the difference between the bounds and the point estimate. So
M = 8686 - 6995 = 6995 - 5304 = 1691
The margin of error is of 1691.
c. Calculate the standard error of the prediction of student expenditures at a university with a graduation rate of 40%.
Now I have to expand a bit into the confidence interval.
We have that to find our \(\alpha\) level, that is the subtraction of 1 by the confidence interval divided by 2. So:
\(\alpha = \frac{1 - 0.9}{2} = 0.05\)
Now, we have to find z in the Ztable as such z has a pvalue of \(1 - \alpha\).
That is z with a pvalue of \(1 - 0.05 = 0.95\), so Z = 1.645.
The margin of error is:
\(M = zs\)
In which s is the margin of error.
We have that M = 1691. So
\(M = zs\)
\(s = \frac{M}{z} = \frac{1645}{1.645} = 1000\)
The standard error is of 1000

Using Vertical Angles to find Unknown Values What is m
Answers
Vertical angles measure the same, then angle TRS is equal to VRW, and angle SRW is equal to TRV.
Also, the addition of these 4 angles is equal to 360°.
First, we need to find TRS and VRW:
\(\begin{gathered} \measuredangle TRS=\measuredangle VRW \\ 2x+18=3x \\ 18=3x-2x \\ 18=x \\ \\ \measuredangle VRW=3*18=54\degree \\ \measuredangle TRS=54\degree \end{gathered}\)Now, the addition of the 4 angles is given by:
\(\begin{gathered} \measuredangle TRS+\measuredangle VRW+\measuredangle TRV+\measuredangle SRW=360\degree \\ 54\degree+54\degree+\measuredangle TRV+\measuredangle SRW=360\degree \\ \measuredangle TRV+\measuredangle SRW=360\degree-54\degree-54\degree \\ \measuredangle TRV+\measuredangle SRW=252\degree \end{gathered}\)Also TRV=SRW, so by replacing this:
\(\begin{gathered} \measuredangle SRW+\measuredangle SRW=252\degree \\ 2\measuredangle SRW=252\degree \\ \measuredangle SRW=\frac{252\degree}{2} \\ \\ \measuredangle SRW=126\degree \end{gathered}\)The m

PLS HELP ILL MARK BRAINLIEST!!! Pencey High School has 1200 students currently enrolled. A random sample of 25 students shows that 19 arrive to school by bus. Predict the number of students in the school who arrive by bus.
Answers
Answer: 912 students
Step-by-step explanation:
We can use the concept of proportion to make a prediction. If 19 out of 25 students arrive by bus, then the proportion of students who arrive by bus can be estimated as:
19/25 = x/1200
Solving for x, we get:
x = (19/25) * 1200 = 912
Therefore, we can predict that around 912 students in Pencey High School arrive by bus.

THE ONE-EYED JACK MINE INVESTIGATION
The abandoned One-Eyed Jack Mine is about 31 miles off the main road adjacent to the Salmon River Wilderness area. There is only a rutted dirt track left where the access road used to run. It is so steep that when we hiked up it we had to pause every fifty feet or so to catch our breath. It seemed impossible but 3- 5 miles further we found remnants of the old wagons, the mineshaft, and the mill. The gold ore found in this mine was embedded in quartz and prospectors used the mill to grind up the quartz and rinse it with acid in huge shallow vats that were agitated so that the gold would sink to the bottom and the quartz could be washed away.
One arrangement of equipment we noticed included a circular vat about 18 feet in diameter which must have been connected by a huge belt to a smaller circular drive wheel 10 feet in diameter. The distance between the wheel and the vat was 8 feet. The equipment had been partially pre-fabricated then carried up the hill piece by piece to be re-assembled on the spot. Just the belt to connect the vat to the drive wheel would have been a major burden. We wondered how many times they had to carry new ones up to replace it. Calculate the length of belt needed to go around the drive wheel and the vat.
Answers
Answer:
The circumference of the drive wheel is 10 feet * 3.14 = 31.4 feet.
The circumference of the vat is 18 feet * 3.14 = 56.52 feet.
The total length of belt needed to go around the drive wheel and the vat is 31.4 + 56.52 = 87.92 feet.

The value of m that satisfies the equation -3 + m = 9 is m = 12.
To solve the equation -3 + m = 9, we can isolate the variable m by moving the constant term -3 to the other side of the equation.
-3 + m = 9
To move -3 to the other side, we can add 3 to both sides of the equation:
-3 + 3 + m = 9 + 3
Simplifying, we have:
m = 12
Therefore, the value of m that satisfies the equation -3 + m = 9 is m = 12.

How to obtain the mean of a data-set?The mean of a data-set is obtained as the sum of all observations in the data-set divided by the number of observations in the data-set, which is also called the cardinality of the data-set.
The dot plot shows how often each observation appears in the data-set, hence the mean of the data-set is obtained as follows:
Mean = (1 x 0 + 5 x 1 + 3 x 2 + 5 x 3 + 1 x 4)/(1 + 5 + 3 + 5 + 1)
Mean = 2.
The range is the difference between the largest observation and the smallest, hence:
4 - 0 = 4.

Find the value of x.
Answers
Answer:
x = 61
Step-by-step explanation:
x and 29 are complementary angles so they add to 90 degrees
x+29 = 90
Subtract 29 from each side
x+29-29 = 90-29
x = 61
Answer:
61 degrees = x
Step-by-step explanation:
Since angle measures x and 29 are complementary angles, subtract 29 from 90 degrees.
90 - 29 = 61 degrees is the value of x

(please help me if I don't get help I won't graduate)
Answers
James owns just 5% of the company after the investment.
What is a percentage?Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100.
Percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%".
Percentage can be calculated by dividing the value by the total value, and then multiplying the result by 100. It is given by:
Percentage = (value / total value) * 100%
How to find the Percentage owned by James;
James' investment: $10,000
The other 3 people invested;
x = $10,000
y = $10,000
z = $10,000
Total investment made was = $200,000
James' Percentage = \(\frac{10000}{200000\\}\) x 100
James' Percentage = 5%
So, we can say that James owns 5% of the total investment in the business.

I need also help on -2(x+3)=_-6
Answers
The solution to the equation -2(x + 3) = -6 is x = 0.
To simplify the expression 5t + 7 + 8b, we can combine like terms.
There are two like terms in the expression: 5t and 8b.
Combining the like terms gives us:
5t + 8b + 7
Therefore, the simplified form of the expression 5t + 7 + 8b is 5t + 8b + 7.
Regarding the equation -2(x + 3) = -6:
To solve this equation, we can follow these steps:
Distribute the -2 to the terms inside the parentheses:
-2 * x + (-2) * 3 = -6
This simplifies to:
-2x - 6 = -6
Move the constant term to the right side by adding 6 to both sides of the equation:
-2x = 0
Divide both sides of the equation by -2 to isolate the variable x:
x = 0 / -2
Simplifying the right side of the equation gives us:
x = 0
The solution to the equation -2(x + 3) = -6 is x = 0.
The simplified expression 5t + 7 + 8b remains as 5t + 8b + 7, and the solution to the equation -2(x + 3) = -6 is x = 0.
