use the equations for the total cost c and total revenue r to find the number x of units a company must sell to break even. (round to the nearest whole unit.) c=850x+250000 R=9502x
To break even, 29 units must always be sold. The cost will be $850 per unit, or $24,650.
Define the term break even point? The break-even threshold is reached when overall costs and total revenues are equal, leaving your small firm with no net benefit or loss. In many other words, you've achieved the point in production where the revenue from a product equals the cost of manufacture.For the given question-
Total cost c: c = 850x + 250000
Total revenue R: R = 9502x
The point during which costs equal revenues is known as the break-even point.
850x + 250000 = 9502x
9502x - 850x = 250000
8652x = 250000
x = 28.29
x = 29
Thus, to break even, 29 units must always be sold. The cost will be $850 per unit, or $24,650.

Naomi is working two summer jobs, making $10 per hour washing cars and $12 per hour tutoring. Last week Naomi earned a total of $108 and worked 2 more hours washing cars than hours tutoring. Determine the number of hours Naomi worked washing cars last week and the number of hours she worked tutoring last week.
Answer: 6 hours washing cars and 4 hours tutoring
Step-by-step explanation:
# of hours washing cars can be represented as x
# of hours tutoring can be represented by y
10x + 12y = $108
y + 2 = x
10 (y +2) + 12y = 108
10y + 20 + 12y = 108
22y + 20 = 108
22y = 88
y = 4 hrs tutoring
4 + 2 = 6 hrs washing cars
Check:
10(6) + 4(12) = 108
108 = 108
The number of hours Naomi worked washing cars last week and the number of hours she worked tutoring last week will be 4 and 6 hours respectively.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, Naomi is earning $10 per hour washing cars and $12 per hour tutoring during the summer. Naomi worked 2 more hours washing cars last week than tutoring, earning a total of $108.
Suppose the number of hours invested in washing cars is x and tutoring be y.
It is given that, Naomi is earning $10 per hour washing cars and $12 per hour tutoring during the summer and earning a total of $108.The obtained equation is
10x + 12y = $108 -----(1)
If Naomi worked 2 more hours washing cars last week than tutoring. The obtained equation is
y + 2 = x -----(2)
Substitute the value of y in equation 1
10 (y +2) + 12y = 108
10y + 20 + 12y = 108
22y + 20 = 108
22y = 88
y = 4 hrs
The value of x is,
x=y+2
x=4+2
x=6
Thus, the number of hours Naomi worked washing cars last week and the number of hours she worked tutoring last week will be 4 and 6 hours respectively.

Celine i etimating the number of tile in a moaic. There are 7 different color, and 472 tile of each color. There are alo 96 blank tile. What hould Celine’ etimate be?
Celine should estimate 3400 tiles in a mosaic.
The total number of tiles in mosaic will be sum of coloured tiles and blank tiles. So, there is a variety in coloured tiles. To calculate this we will perform multiplication.
Number of coloured tiles = Number of different coloured tiles × Number of each different coloured tile
Number of coloured tiles = 7 × 472
Performing multiplication on Right Hand Side of the equation
Number of coloured tiles = 3304
Total number of tiles = 3304 + 96
Performing addition on Right Hand Side of the equation
Total number of tiles = 3400 tiles

A football team owner believes that attendance at the home stadium increases when the team
has a winning season. He randomly selects 10 seasons when the team won more games than
they lost and determines that the mean attendance is 88,532 people with a standard deviation
of 1341 people. Ten more seasons are randomly selected from years when the team lost more
games than they won. The mean attendance for the sample of losing seasons is 86,910 people
with a standard deviation of 1521 people. Assume all conditions for conducting a
significance test have been met and that the p-value is 0.011. Which of the following
conclusions should the owner make?
A) The mean attendance at the home stadium is greater when the team is having a winning
season approximately 1.1% of the time.
B) The p-value indicates that the mean attendance at the home stadium is greater when the
team is having a winning season at the 1% level of significance. There is a significant
difference in mean attendance when the team is winning than when the team is losing.
At the 5% significance level, there is evidence that the mean attendance at the home
stadium is greater when the team is having a winning season than when the team is
having a losing season. We would expect to get a test statistic at least as extreme as the
one observed 1.1% of the time if the null hypothesis is true.
D) At the 5% significance level, there is evidence that the mean attendance at the home
stadium is greater when the team is having a winning season than when the team is
having a losing seasen. We would expect to get a test statistic at least as extreme as that
observed 98.9% of the time if the null hypothesis is true.
E Because the p-value is so small, the results show that there is not a significant
difference between the mean attendance during a winning season and the mean
attendance during a losing season.
Answer:
ИДК либо плохо так грустно для вас ха-ха
Option B correctly summarizes these conclusions and provides additional information about the level of significance and the expected frequency of getting a test statistic as extreme as the observed one if the null hypothesis is true.
Option B is the correct answer.
What is hypothesis testing?Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.
It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.
We have,
The p-value of 0.011 is less than the significance level of 0.05, which means that we reject the null hypothesis that there is no difference in mean attendance between winning and losing seasons.
Therefore, we conclude that there is evidence to support the claim that mean attendance at the home stadium is greater when the team is having a winning season than when the team is having a losing season.

Step-by-step explanation:
amy currently had a balance of 12.56 in her checking account. her bank account required to obtain a minimum balance of 30$, how much money does amy need to deposit to reach the minimum balance
Money that needs to be deposited to reach the minimum balance is $17.44
How to calculate the deposit amount?Current balance of Amy = C= $12.56
Minimum balance amount = M = $30
The amount to be deposited = Minimum balance amount - Current balance amount
= M - C
=$30 - $12.56
= $17.44
The deposit amount required from Amy= $17.44
What is minimum balance?The minimal quantity of money one must maintain in our bank account to avoid paying a monthly fee is known as a minimum balance requirement. One can avoid the charge by keeping the minimum balance. If we fall short of it, we'll have to pay a fee for the month. Online banks sometimes do not have any minimum balance restrictions because one of their advantages is that they have reduced fees. The least amount of money that must be in our account at the end of each day is called a minimal daily balance.

What is supplementary angle ?
Two angles are said to be supplementary if their sums total 180 degrees. A linear pair's two angles, like angles 1 and 2 in the illustration below, are always supplementary. But two angles don't have to be close to one another to be supplementary. Since their measures sum up to 180 degrees, the numbers 3 and 4 in the following figure are supplementary.
Two Angles are Supplementary when they add up to 180 degrees.
From given figure,
It is observed that sum of ∠7 and ∠8 is equal to 180 degrees.
The sum of ∠7 and ∠5 is equals to 180 degrees.

The coordinates of B is (8,-3).
Given:
The midpoint of AB is M(7, -5)
the coordinates of A are (6, -7)
Midpoint = (x1+x2 / 2 , y1+y2 / 2)
(7,-5) = (6+x2 /2 , -7+y2 /2)
7 = 6+x2 / 2
14 = 6 + x2
x2 = 14 -6
x2 = 8
-5 = -7+y2 / 2
-10 = -7 + y2
y2 = -10+7
y2 = -3
Therefore the coordinates of B is (8,-3).
