Graph the following equation -3y+6x+=6
Answer:
Step-by-step explanation: Here's a step-by-step guide on how to graph the equation -3y + 6x = 6:
Isolate y: To isolate y, first subtract 6x from both sides of the equation: -3y + 6x = 6 => -3y = -6x + 6.
Divide both sides of the equation by -3: Dividing both sides of the equation by -3, we get: -3y / -3 = (-6x + 6) / -3.
Simplify the equation: On simplifying the equation, we get: y = 2x - 2.
Plot the y-intercept: The y-intercept of the equation is when x = 0. So, when x = 0, y = 2 * 0 - 2 = -2. This point is (0, -2). Plot this point on the graph.
Plot a second point: Pick a value of x and plug it into the equation to find the corresponding y value. For example, let's take x = 1. Plugging x = 1 into the equation, we get y = 2 * 1 - 2 = 0. This point is (1, 0). Plot this point on the graph.
Draw the line: Connect the two points plotted on the graph. This line represents the solution set of the equation.
That's it! You have successfully graphed the equation -3y + 6x = 6.

Eighteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, eight of whom will be taking the test for the first time. Suppose that six of these individuals are randomly assigned to a particular examiner, and let X be the number among the six who are taking the test for the first time. a. What kind of a distribution does X have (name and values of all parameters)
Answer:
X has an hypergeometric distribution, with parameters:
Size of the population is N = 18.
Size of the sample is n = 6.
Number of successes n is k = 8.
Step-by-step explanation:
The people are chosen without replacement, which means that the hypergeometric distribution is used.
Hypergeometric distribution:
The probability of x sucesses is given by the following formula:
\(P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}\)
In which:
x is the number of sucesses.
N is the size of the population.
n is the size of the sample.
k is the total number of desired outcomes.
Combinations formula:
\(C_{n,x}\) is the number of different combinations of x objects from a set of n elements, given by the following formula.
\(C_{n,x} = \frac{n!}{x!(n-x)!}\)
Eighteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, eight of whom will be taking the test for the first time.
This means that \(N = 18, k = 8\)
We consider a success being a person taking the test for the first time, because X is the number among the six who are taking the test for the first time.
Suppose that six of these individuals are randomly assigned to a particular examiner.
This means that \(n = 6\)
a. What kind of a distribution does X have (name and values of all parameters)

What is equation rearrangement?
Equation rearrangement is a process of arranging the equation parameters in terms of a specific parameter.
Given is a phone company that charges a base fee of $12 per month plus an additional charge per minute. The monthly phone charge cost [c] can be represented by the equation: c = 12 + a x m, where [a] is the additional charge per minute, and [m] is the number of minutes used.
The given equation is -
c = 12 + a x m
Since, we know the values of [a] and [c], we can solve for [m] as follows -
c = 12 + a x m
c - 12 = a x m
m = (c - 12)/a
Therefore, the equation that can be used to find the number of minutes[m] a customer used is -
m = (c - 12)/a

Solve the inequality and graph the solution on the line provided. 6x-6<-30
The solution to the inequality 6x - 6 < -30 is x < -4, and it is graphically represented as a closed circle at -4 and shading to the left of -4 on the number line.
To solve the inequality 6x - 6 < -30, we can follow these steps:
Step 1: Add 6 to both sides of the inequality to isolate the variable:
6x - 6 + 6 < -30 + 6
6x < -24
Step 2: Divide both sides of the inequality by 6 to solve for x:
(6x)/6 < (-24)/6
x < -4
The solution to the inequality is x < -4. This means that any value of x less than -4 will satisfy the inequality.
To graph the solution on the number line, we represent -4 as a closed circle (since it is not included in the solution) and shade the region to the left of -4 to indicate all values less than -4.
On the number line, mark a point at -4 with a closed circle:

How many gallons of 60% antifreeze solution must be mixed with 70 gallons of 20% antifreeze to get a mixture that is 50% antifreeze.
(Round to the nearest whole number)
Answer:
Answer: Add 315 gallons of 70% antifreeze to 90 gallons of 25% antifreeze to make a 60% mixture.
You need to end up a mixture that is 60% antifreeze.
You have 90 gallons of 25% antifreeze, which means it has .25*90 = 22.5 gallons of pure antifreeze mixed with a solvent (probably water).
.
You will add 'x' gallons of 70% antifreeze to make the 60% mixture.
So, at the conclusion, you will have (90+x) gallons 60% 'pure' antifreeze. That can be shown with the equation:
.
.25*90 + .7*x = .6*(90+x)
.
Multiply by 100 to eliminate fractions.
.
25*90 + 70x = 60(90 +x)
.
2250 + 70x = 5400 + 60x
.
10x = 5400 -2250
.
10x = 3150
.
x = 315 gallons of 70% antifreeze.
.
How much will you end up having on hand?
90 + 315 = 405 gallons
.
If it is 60% antifreeze, how much 'pure' antifreeze will be in the mixture?
.6*405 = 243
.
In the original 90 gallons, you have 22.5 gallons of pure antifreeze.
In the additional 315 gallons, you have .7*315 = 220.5 gallons.
22.5+220.5 = 243 gallons

The mean price of a gallon of milk at various stores is $2.60 with a standard deviation of $0.15. If the cost of milk at Target is 3 standard
deviations above the mean, how much does it cost?
Answer: The cost of milk at Target is 3 standard deviations above the mean = $3.05.
Step-by-step explanation:
Given: Mean price of a gallon of milk = $2.60
Standard deviation = $0.15
The cost of milk at Target is 3 standard deviations above the mean = Mean + Standard deviation
= $ (2.60+3(0.15))
=-$(2.60+0.45)
= $ 3.05
Hence, the cost of milk at Target is 3 standard deviations above the mean = $3.05.
The changes in housing prices over short time periods are in part determined by supply and demand. A real estate company in Minnesota projected an increase in its average selling prices of homes in the first quarter of 2014 over the mean 2013 selling price of $201,800. The reason for the projection was an increase in demand due to business expansion and the subsequent increase in labor. To investigate the accuracy of the projection, a sample of homes in the first quarter of 2014 was selected and the following selling prices (in $) recorded:
235,000 271,900 183,300 203,000 182,900 225,500 189,000 214,200 237,900 233,500 217,000 230,400 202,950, 216,500 209,900, 245,500

a. At 5% level of significance, is there sufficient evidence to support the real estate company's projection?
b. Which statistical distribution should be applied in this situation and why? Explain carefully.
c. Discuss the consequences of Type I and Type II errors in terms of the problem.
d. Does the management at the real estate company want a small or large value of the significance level? Explain carefully.
e. Based on a 95% confidence level, estimate the actual average selling price homes in the first quarter of 2014.
Answer:
The data given is
235,000 271,900 183,300 203,000 182,900 225,500 189,000 214,200 237,900 233,500 217,000 230,400 202,950, 216,500 209,900, 245,500
The sample size is n = 16
The population is \(\mu = \$201,800\)
The sample mean is mathematically represented as
\(\= x =\frac{\sum x_i}{n}\)
=> \(\= x =\frac{235,000 + 271,900 + \cdots + 245,500 }{16}\)
=> \(\= x = 218653.125\)
Generally the sample standard deviation is mathematically represented as
\(s = \sqrt{\frac{\sum (x_i - \= x)^2}{n} }\)
=> \(s = \sqrt{\frac{ (235,000 - 218653.125)^2+ (271,900 - 218653.125)^2 + \cdots + (245,500 - 218653.125)^2}{16} }\)
=> \(s = 23946.896 \)
The null hypothesis is \(H_o : \mu = \$201,800\)
The alternatively hypothesis is \(H_o : \mu > \$201,800 \)
Generally the test statistics is mathematically represented as
\(t = \frac{\= x - \mu }{ \frac{s}{\sqrt{n} } }\)
=> \(t = \frac{218653.125 - 201800 }{ \frac{23946.896 }{\sqrt{16} } }\)
=> \(t = 2.82\)
Generally the degree of freedom is mathematically represented as
\(df = n - 1\)
=> \(df = 16 - 1\)
=> \(df = 15\)
Generally the probability of \(t = 2.82\) at a degree of freedom of \(df = 15\) from the t - distribution table is
\(p-value = P( t >2.82 ) =0.00646356\)
The
From the values obtained we see that \(p-value < \alpha\)
The decision rule is
Reject the null hypothesis
The conclusion is
There is sufficient evidence to conclude that the real estate company's projection is true
Given that the population variance is unknown then the best statistical distribution to be applied is the t -distribution
Type I Error
The type 1 error occur when the null hypothesis is wrongfully rejected
The consequence in this case is the company will assume that the average selling price has increase and this will lead the company to start expanding the business while in the real sense the average selling price is still $201,800
Type II Error
The type 11 error occur when the null hypothesis is wrongfully accepted(i.e wrongfully failed to reject the null hypothesis)
The consequence in this case is that the company will assume that the average selling price is still $201,800 and will not make plans to increase the business while in the real sense the average selling price has increased
Given that resource is scare the management of the company will want a smaller significance level in order not to commit type I error which will lead to wrongly expanding the business and wastes of resources
generally the critical value of \(\frac{\alpha }{2}\) from the normal distribution table is
\(Z_{\frac{\alpha }{2} } = 1.96\)
Generally the margin of error is mathematically represented as
\(E =Z_{\frac{\alpha }{2} } * \frac{s}{\sqrt{n} }\)
=>\(E =1.96* \frac{23946.896}{\sqrt{16} }\)
=>\(E = 11733.96\)
Generally the 95% confidence interval is mathematically represented as
\(218653.125 - 11733.96 < \mu < 218653.125 + 11733.96\)
=> \(206919.165 < \mu < 230387.085\)
Generally there is 95% confidence that the actual average selling price is within this interval

Water flows at a steady rate from a tap.
It takes 40 seconds to fill a 4 litre watering can from the tap
The rate at which the water is now flowing from the tap is 50 cubic centimeters per second.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
In other words it compares 1 unit of some quantity with different amount of another quantity.
Given that,
Time taken to fill the watering can of 4 liter = 40 seconds.
4 liter = 4000 cm³
Time taken to fill the watering can of 4000 cm³ = 40 seconds
Unit rate of flow of water = 4000 / 40 = 100 cm³ / sec
Now the rate at which water flows is halved.
Rate = 100 / 2 = 50 cm³ / sec

how much money deposited now will provide payment of Rs. 15000 at the end of each half year for 10 years, if interest is 16% compounded six-monthly
The interest is 16% compounded semi-annually, is Rs. 121,179.10.
To determine how much money needs to be deposited now to provide a payment of Rs. 15,000 at the end of each half year for 10 years, we will use the formula for the present value of an annuity.
Present value of an annuity = (Payment amount x (1 - (1 + r)^-n))/rWhere:r = interest rate per compounding periodn = number of compounding periodsPayment amount = Rs. 15,000n = 10 x 2 = 20 (since there are 2 half years in a year and the payments are made for 10 years)
So, we have:r = 16%/2 = 8% (since the interest is compounded semi-annually)Payment amount = Rs. 15,000Using the above formula, we can calculate the present value of the annuity as follows:
Present value of annuity = (15000 x (1 - (1 + 0.08)^-20))/0.08 = Rs. 121,179.10Therefore, the amount that needs to be deposited now to provide payment of Rs. 15,000 at the end of each half year for 10 years, if the interest is 16% compounded semi-annually, is Rs. 121,179.10.

The value of x for the given equation \(-\frac{1}{2}\) |2x + 6| + 2 = 0 is x = -1,-5.
What are absolute value functions?An absolute value function is a useful algebra function composed of the variables in the absolute value bars. The absolute value function has the general form f(x) = a |x - h| + k, and the most commonly used form is f(x) = |x|, where a = 1 and h = k = 0. The absolute value function f(x) = |x| has a non-negative range and can be written as x if x 0 and -x if x 0 by expanding the function f(x) = |x|.
The given equation is \(-\frac{1}{2}\) |2x + 6| + 2 = 0.
Combine |2 x+6| and 1/2.
- \(\frac{|2 x+6|}{2}\) + 2 = 0
Subtract 2 from both sides of the equation.
- \(\frac{|2 x+6|}{2}\) = -2
Multiply both sides of the equation by -2.
-2 (- \(\frac{|2 x+6|}{2}\) ) = -2 × -2
Simplify both sides of the equation.
|2 x+6|=4
Remove the absolute value term. This creates a \($\pm$\) on the right side of the equation |x|= \($\pm$\) x.
