Complete the table for the equation y = x - 2. Then use the table to graph the equation.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the equation
[tex]y = x-2[/tex]
comparing with the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept
so
The slope of the line y = x-2 will be: m = 1The y-intercept of the line = b = -2Let us plug in some values
at x = 0, y = x-2 ⇒ y = 0-2 ⇒ y = -2
at x = 1, y = x-2 ⇒ y = 1-2 ⇒ y = -1
at x = 2, y = x-2 ⇒ y = 2-2 ⇒ y = 0
at x = 3, y = x-2 ⇒ y = 3-2 ⇒ y = 1
at x = 4, y = 4-2 ⇒ y = 4-2 ⇒ y = 2
Thus, the table of the equation y = x-2 becomes

HELP THIS IS DUE IN ONE HOUR I NEED A GOOD ANSWER! Each sales associate at an electronics store has a choice of the two salary options shown below.
• $115 per week plus 9.5% commission on the associate’s total sales
• $450 per week with no commission
a. The average of the total sales amount for each associate last year was $125,000. Based on this average, which salary option would result in a higher salary?
b. What is the difference between the two salary options?
Answer:
A) The best option would be a fixed weekly salary of $ 450.
B) The difference between the two options is $ 106.64.
Step-by-step explanation:
A) To determine which option would result in a better salary, knowing that on the one hand you can have a fixed salary of $ 450 per week without commission, while on the other you can have a salary of $ 115 per week plus a commission of 9.5% on the total sales of Each associate, knowing that the average annual sales of each associate in the last year was $ 125,000 and that each year has 52 weeks, the following calculation must be made:
125,000 / 52 = Average sales per week
2,403.84 = Average sales per week
2,403.84 x 0.095 = Weekly commission
228.36 = Weekly commission
228.36 + 115 = Weekly salary
343.36 = Weekly salary
Therefore, the best option would be a fixed weekly salary of $ 450.
B) The difference between both options arises from the subtraction between each amount received by the worker, that is:
450 - 343.36 = X
106.64 = X
Therefore, the difference between the two options is $ 106.64.

A landscape contractor wants to make an exposed gravel border of uniform width around a rectangular pool in a garden. The pool is 10 feet long and 6 feet wide. There is enough material to cover 36 square feet. How wide should the border be
Answer:
Border should be 1 ft wide
Step-by-step explanation:
The pool is 10 feet long and 6 feet wide.
Now, since the landscape contractor wants to make an exposed gravel border of uniform width. Let the uniform width of the border be x. Thus it means the length is now (10 + 2x) and width is now (6 + 2x).
We are told there is enough material to cover 36 square feet.. Thus;
New area - old area = 36
[(10 + 2x) × (6 + 2x)] - (10 × 60) = 36
4x² + 32x + 60 - 60 = 36
4x² + 32x = 36
Subtract 36 from both sides to get;
4x² + 32x - 36 = 0
Using quadratic formula, we have;
x = -9 or 1
We will pick the positive value as the width can't be negative.
Thus;
x = 1 ft

The crisis in the housing market during the most recent economic recession led to lower vacancy rates in the apartment industry. This, in turn, has resulted in an increase in monthly rents for apartments. Suppose a random sample of 40 apartments had an average rent of $1,090. Assume the standard deviation for the population of apartment rents is $260. Determine the 98% confidence interval for this sample.
Answer:
(994.37, 1185.62)
Step-by-step explanation:
Given that :
Mean (m) = 1090
Standard deviation (s) = 260
Samole size (n) = 40
α = 98%
Using the relation :
Confidence interval = mean ± Error
Error = Zcritical * (standard deviation / sqrt (n))
Zcritical at 98% = 2.326
Error = 2.326 * (260 / sqrt(40))
Error = 95.620951
Hence,
Confidence interval :
Lower boundary = 1090 - 95.620951 = 994.379049
Upper boundary = 1090 + 95.620951 = 1185.620951
(994.37, 1185.62)
In 2000, in order to reduce the unemployment rate, France mandated all employers with 20 or more employees to reduce the workweek to 35 hours. Prior to the new law, the unemployment rate in France was 12%. In a random sample of 500 French workers taken a few years after the new law went into effect, 53 workers were found to be unemployed. Using the p-value method, conduct a hypothesis test to determine if the French unemployment rate dropped after the enactment of the 35- hour workweek law. Assume the significance level as 0.05. (7 Points)
Answer:
We accept H₀ for a CI = 95 % we din´t find differences in the unemployment level
Step-by-step explanation:
p₀ = 12 % p₀ = 0,12
From sample p = 53/500 p = 0,106
Test Hypothesis
Null Hypothesis H₀ p = p₀
Alternative Hypothesis Hₐ p < p₀
p₀*n = 0,12*500 = 60
q₀ * n = 0,88 * 500 = 440
Then the binomial distribution can be approximate to a normal distribution
The significance level α = 0,05 CI = 95 %
We need to develop a one-tail test (to the left ) find p-value and compare it with α.
p(s) = ( p - p₀ ) / √ p*q /n
p(s) = 0,106 - 0,12 / √(0,12)*(0,88)/500
p(s) = - 0,014 / 0,015
p(s) = - 0,93
With this P score we find the area under the bell shape curve
p-value = 0,1762 and compare that area with α = 0,05
Then p-value > 0,05
Therefore we accept H₀

Answer:
srt is 33
srq is 66
trq is 33
Answer:
∠SRT = 33°
Step-by-step explanation:
To track what angle they're talking about, connect the letters listed for each angle like connect the dots.
∠QRT is 33°
RT bisects ∠SRQ, meaning it's in the middle of it.
So half of ∠SRQ is 33°, meaning the full angle is double that: 66°
That also means that the other half of the angle is equal to the first half. ∠SRT=33°

Solve the equation and check your solution.
3x − 6 = 4(2 − 3x) − 8x
Answer:
x = 14/23
Step-by-step explanation:
3x − 6 = 4(2 − 3x) − 8x
3x − 6 = 8-12x − 8x
3x=14-20x
23x=14
x= 14/23
3(14/23)-6=4(2 − 3(14/23) − 8(14/23)
And solve hope this helps. Remember to isolate the variable when finding x for next time.
The solution to the given equation is x = 14/23.
To solve the equation 3x - 6 = 4(2 - 3x) - 8x, we will simplify and solve for x:
First, let's distribute 4 to the terms inside the parentheses on the right side of the equation:
3x - 6 = 8 - 12x - 8x
Next, let's combine like terms on the right side of the equation:
3x - 6 = -20x + 8
Now, let's bring all the x terms to one side of the equation by adding 20x to both sides:
3x + 20x - 6 = -20x + 20x + 8
This simplifies to:
23x - 6 = 8
Next, let's isolate the x term by adding 6 to both sides:
23x - 6 + 6 = 8 + 6
This simplifies to:
23x = 14
Finally, divide both sides by 23 to solve for x:
x = 14/23
So, the solution to the equation is x = 14/23.
To check the solution, substitute x = 14/23 back into the original equation:
3(14/23) - 6 = 4(2 - 3(14/23)) - 8(14/23)
This simplifies to:
42/23 - 6 = 8/23 - 12(14/23) - 112/23
-132/23 = -132/23
Both sides of the equation are equal, confirming that x = 14/23 is the correct solution.

1. A company that produces bread is concerned about the distribution of the amount of sodium in its bread. The company takes a simple random sample of 100 slices of bread and computes the sample mean to be 103 milligrams of sodium per slice. Assume that the population standard deviation is 10 milligrams. a) Construct a 95% confidence interval estimate for the mean sodium level. b) Construct a 99% confidence interval estimate for the mean sodium level.
Answer:
The 95% confidence interval is [tex] 101.13 < \mu < 104.87 [/tex]
The 99% confidence interval is [tex] 100.54 < \mu < 105.46 [/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 110
The sample mean is [tex]\= x = 103 \ mg[/tex]
The population standard deviation is [tex]\sigma = 10 \ mg[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 1.96 * \frac{ 10 }{\sqrt{110} }[/tex]
=> [tex]E =1.8688 [/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\= x -E < \mu < \=x +E[/tex]
=> [tex]103 - 1.8688 < \mu < 103 + 1.8688 [/tex]
=> [tex] 101.13 < \mu < 104.87 [/tex]
Considering question b
From the question we are told the confidence level is 99% , hence the level of significance is
[tex]\alpha = (100 - 99 ) \%[/tex]
=> [tex]\alpha = 0.01[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 2.58[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]E = 2.58 * \frac{ 10 }{\sqrt{110} }[/tex]
=> [tex]E =2.4599 [/tex]
Generally 99% confidence interval is mathematically represented as
[tex]\= x -E < \mu < \=x +E[/tex]
=> [tex]103 - 2.4599 < \mu <103 + 2.4599 [/tex]
=> [tex] 100.54 < \mu < 105.46 [/tex]
