Answers
The coordinates of B are (-7,-2).
What do you mean by x and y coordinates?
The x and y coordinates are a component of the x-axis and y-axis in a 2D space in the Cartesian coordinate system. The x and y coordinates for a point in space are expressed as an ordered pair (x, y). The position of the point on the x-axis is shown by the first number, while its location on the y-axis is indicated by the second number.
According to the given data in the question,
if M is the location where line segment AB meets its midpoint.
Then, we will using the midpoint formula,
[tex](-5,2)=(\frac{-3+x}{2},\frac{6+y}{2})..............(1)[/tex]
Putting the x-coordinates in (1),
[tex]-5=\frac{-3+x}{2}\\ -10=-3+x\\-10+3=x\\x=-7[/tex]
Similarly, putting the y-coordinates in (1),
[tex]2=\frac{6+y}{2} \\4=6+y\\4-6=y\\y=-2[/tex]
Hence, the coordinates of B are (-7,-2).

Ralph wants to join a travel soccer team, a discretionary expense. His parents tell him he must get a job to earn the money to cover the costs. Ralph now views this discretionary expense as an
essential expense since he must pay his parents back. The costs of the travel team are listed below.
Find the total cost of being on the team.
If Ralph takes a summer job and works 10 weeks over the summer, how much must be average each week to cover the travel team expenses?
If Ralph is paid at a flat rate of exactly q dollars each week, what is the standard deviation of the distribution of his 10 weekly paychecks?
Answers
The total cost to be in the team will be $1192. He must earn an average of $119.2 per week for 10 weeks. If Ralph is paid at a flat rate of exactly q dollars each week, so the standard deviation will $0.
What is total cost?Total cost is the sum of all expenditures made to produce a certain level of output; when this total cost is divided by the quantity produced, average or unit cost is discovered. The sum of the fixed and variable costs is the total cost. For instance, if a company has a fixed cost per unit of $30 and a variable cost per unit of $5 that increases as output increases, the total cost will be $35. Total cost is equal to the sum of all fixed and variable costs. Total Cost = (Average Fixed Cost + Average Variable Cost) x Number of Units is another way to express it. All of this had to do with the total cost formula, which is a crucial idea for figuring out the total cost of production.
Here,
The expenses of team is,
Uniform=$67.00
Registration=$50.00
Tournaments=$775.00
Travel =$300.00
Total cost=sum of all expense
=67+50+775+300
=$1192
Average cost=Total cost/number of weeks he worked
=1192/10
=$119.2
Deviation of distribution cost,
If Ralph is paid at a flat rate of exactly q dollars each week then there will be $0 deviation.
It will cost $1192 in total to join the team. For ten weeks, he must make an average of $119.2 per week. If Ralph receives a fixed weekly salary of exactly q dollars, the standard deviation will be zero.

A dairy farmer wants to mix a 45% protein supplement and a standard 20% protein ration to make 2000 pounds of a high-grade 35% protein ration. How many pounds of each should he use?
Answers
The farmer should use 1200 pounds of type 1 mixture and 800 pounds of type 2 mixture to satisfy the given conditions
From given information,
Type 1: 45 percent of protein in the supplement is x pounds
Type 2: 20 percent of the protein in the supplement is (2000 - x) pounds
Also Mixture A 35% of the protein in the supplement is 2000 pounds
According to the equation after removing the percentage sign we have
45x + 20(2000-x)= 35*2000
45x + 40000 - 20x = 70000
25x = 30000
x = 1200
Now for type 2 mixture we have

Answers
The equation have the same solution as 2.3p – 10.1 = 6.49p – 4 and 230p – 1010 = 650p – 400 – p
How to determine the equations that have the same solution?Given: 2.3p – 10.1 = 6.5p – 4 – 0.01p.
Using this given property, let's write the equation
We can subtract like terms (6.5p– 0.01p = 6.49p) to get:
2.3p – 10.1 = 6.5p – 0.01p – 4
2.3p – 10.1 = 6.49p – 4
Also, we can multiply both sides of the algebraic equation by 100:
(2.3p – 10.1) x 100 = (6.5p – 4 – 0.01p) x 100
230p – 1010 = 650p – 400 – p
Therefore, the equations have the same solution as 2.3p – 10.1 = 6.49p – 4 and 230p – 1010 = 650p – 400 – p. The 2nd and 3rd options are the answers

1. A factory is testing a new machine on its production line that is intended to improve efficiency. Management randomly
selects 12 employees and measures the number of products they complete in one hour when using the new machine. Below
are the results.
Employee 1 2 3 4 5 6 7 8 9 10 11 12
# units 72 68 74 78 75 79 71 69 82 71 73 80
(a) Estimate at the 95% confidence level the average number of units an employee can produce in one hour using the
new machine.
(b) The manufacturer of the machine claims the typical efficiency for a factory worker should be 78 units per hour. What
does the interval suggest about the manufacturer’s claim
(c) An investigation at a similar factory estimates the standard deviation to be 3.91 units. Using this information, what
size sample should we select to estimate the mean number of units produced each hour to within 1.04 units at the
95% confidence level?
Answers
a) The confidence interval is given as follows: (71.43, 77.17).
b) The manufacturer's claim is not correct, as 78 is not a part of the interval.
c) A sample of 55 employees is needed to achieve the desired margin of error.
What is a t-distribution confidence interval?The bounds of the t-distribution confidence interval, used when only the standard deviation for the sample is known, are given by the equation presented as follows:
[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]
The variables of the equation are presented as follows:
[tex]\overline{x}[/tex] is the sample mean.t is the critical value.n is the sample size.s is the standard deviation for the sample.The critical value, considering the 95% confidence level and 12 - 1 = 11 df, is of:
t = 2.201.
The remaining parameters, namely sample mean, sample standard deviation and sample size are given as follows:
[tex]\overline{x} = 74.3, s = 4.52, n = 12[/tex]
(obtained using a calculator from the sample given in this problem).
The bounds of the interval are given as follows:
Lower bound: 74.3 - 2.201 x 4.52/sqrt(12) = 71.43.Upper bound: 74.3 + 2.201 x 4.52/sqrt(12) = 77.17.The interval does not contain the number 78, hence it is not a good estimate for the mean amount.
For item c, the z-distribution is used, as the population standard deviation is used, hence the minimum sample size is obtained as follows:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]1.04 = 1.96\frac{3.91}{\sqrt{n}}[/tex]
[tex]1.04\sqrt{n} = 1.96 \times 3.91[/tex]
[tex]\sqrt{n} = \frac{1.96 \times 3.91}{1.04}[/tex]
[tex](\sqrt{n})^2 = \left(\frac{1.96 \times 3.91}{1.04}\right)^2[/tex]
n = 55. (rounded up, as a sample size of 54 would mean that the margin of error would be slightly above 1.04).

picnic. Each batch of iced tea makes 30 cups. Which inequality represents the
number of batches b you need to make?
Answers
The required equation of inequality is 4 ≤ b ≤ 6
Given ; Cups of iced tea = 120 cups
and the cups of iced coffee should not be less than 180 cups
Thus this is a question of inequality
Each batch of iced tea makes = 30 cups
thus the required equation is
[tex]\frac{120}{30}[/tex] and this is less than the number of batches which is represented by b
thus the equation would be [tex]\frac{120}{30}[/tex] ≤ b
And it should be less than 180 cups of iced tea
thus the equation would be
b ≤ [tex]\frac{180}{30}[/tex]
Thus the required equation is :
[tex]\frac{120}{30}[/tex] ≤ b ≤ [tex]\frac{180}{30}[/tex]
On simplifying this we will get ;
4 ≤ b ≤ 6

Answers
Equation of the parabola that passes through the points (-4, 7), (-3, 9), and (4,-5) is y = -1/2[tex]x^{2}[/tex] - 3/2 x + 9.
Given points:
(-4, 7), (-3, 9), and (4,-5).
Let parabola equation be y = a[tex]x^{2} +bx+c[/tex].
substitute (-4,7)
7 = a(16)+b(-4)+c
16a-4b+c-7 = 0.
substitute (-3,9)
9 = a(9)+b(-3)+c
9a-3b+c-9 = 0
substitute (4,-5)
-5 = 16a+4b+c
16a+4b+c+5=0.
solving three equations we get,
a = -1/2 , b = -3/2 and c = 9
substitute a,b and c values we get,
y = (-1/2)[tex]x^{2}[/tex] + (-3/2)x + 9
y = -1/2[tex]x^{2}[/tex] - 3/2 x + 9.
Therefore the equation of the parabola that passes through the points (-4, 7), (-3, 9), and (4,-5) is y = -1/2[tex]x^{2}[/tex] - 3/2 x + 9.

The contribution margin rate is 40%.
What is contribution margin rate?
A company's contribution margin rate is the total revenue minus variable costs divided by the revenue.
First we need to determine the contribution margin in order to calculate the contribution margin rate. There are two approaches to determine the contribution margin.
Contribution Margin = Net Sales Revenue – Variable CostContribution Margin = Fixed Costs + Net IncomeContribution Margin = $15 - $9 = $6
The contribution margin is $6.
Now we will calculate the contribution margin rate using this formula,
Contribution Margin Rate = Contribution Margin [tex]/[/tex] Sales Revenue
Contribution Margin Rate = $6 / $15
= 0.4 * 100
= 40%.
Hence the contribution margin rate is 40%.

Find the y intercept and slope of the linear equation
0 = 4.5 - 2y + 4.8x
Answers
Add 2y to both sides
2y=4.8x + 4.5
Divide both sides by 2
Y=4.8x/2 + 4.5/2 = 2.4x + 2.25
This is how linear equations are set up: y=mc + b where m refers to the alive and b refers to the y intercept
Therefore, the slope is 2.4 and the y-intercept is 2.25
