Solve the following system of equations by the method of your choice.
-2x + y = 3
-4x + 2y = -20
a. none of the above
b. infinitely many solutions
c. no solution
d. one solution
Answer:
c. no solution
Step-by-step explanation:
This system of equations has no solution because when graphed, the lines are parallel to each other. Meaning they will never intersect. Since they will never intersect, there are no solutions.
The average response time to a bank robbery is about 9 min. A local community wants to improve on this time, so they implement advanced training seminars. They find that the new response time for a sample of 36 police officers is 8+4.2 (M SD) min. Test whether this advanced training seminar reduced response time at a.05 level of significance. A. This advanced training seminar significantly reduced response time, t(35) 11.43,p <.05 B. This advanced training seminar significantly reduced response time, (35)1.43, p < .05 C. This advanced training seminar did not reduce response time, t(35)--1.43, p> .05. D. There is not enough information to answer this question.
Answer:
The correct option is;
C. This advanced training seminar did not reduce response time, t(35) = -1.43, p > 0.05
Step-by-step explanation:
The given parameters are;
The population mean response time, μ = 9 minutes
The number of police officers in the sample, n = 36
The mean response time after the training, [tex]\overline x[/tex] = 8 minutes
The standard deviation of the response time after the training, s = 4.2 minutes
The level of significance, α = 0.05
The null hypothesis; μ ≥ 9
The alternative hypothesis; μ < 9
The test statistic for the t-test is [tex]t=\dfrac{\bar{x}-\mu }{\dfrac{s}{\sqrt{n}}}[/tex], therefore, we get;
[tex]t=\dfrac{8-9 }{\dfrac{4.2}{\sqrt{36}}} \approx -1.42857142857[/tex]
The degrees of freedom, df = n - 1 = 36 - 1 = 35
The critical-t at 0.05 level of significance is critical-t = 1.69, p(t < -1.43) > 0.05
and, we fail to reject the null hypothesis, therefore, the advanced training did not reduce the response time

Mr. Hoosier has gathered all these data about his finances.
Salary $159,000
Taxable interest $5600
Municipal Bond interest $15,000
Total Itemized deductions $9500
The personal exemption is $4700. The standardized deduction for a single filer is 5000.
Answer:
1. His tax is $37,490.
2. His average effective tax rate is 22%
3. His average tax rate is 24.93%
4. His marginal tax rate is 35%.
5. His tax liability will fall by $170
6. His tax liability will fall by $500.
Step-by-step explanation:
Note: This question is not complete. See the attached pdf file for the complete question.
The explanation of the answer is now given as follows:
1. What is his tax?
Note: See the attached excel for Mr. Hoosier's Tax Computation Based on the Tax Table in the question.
From the attached excel file, the Net tax is $37,490 which is his tax.
Therefore, his tax is $37,490.
2. His average effective tax rate
His average effective tax rate = Tax / (Taxable income + Tax exempt income) = Tax / (Taxable income +Municipal Bond interest) = $37,490 / ($150,400 + $20,000) = 0.2200, or 22%
3. His average tax rate
Average tax rate = Tax / Taxable Income = $37,490 / $150,400 = 24.93%
4. His marginal tax rate
His marginal tax rate is 35% as in the tax computation used based on the tax table.
5. Assume he discovers that he is eligible for a 500 tax deduction. How much does his tax liability fall with that addition?
Taxable income = 150400 - 500 = $149,900
Based on the tax table in the question, we have:
Tax = 8850 + (149900 - 55000) * 30% = $37,320
Reduction in tax liability = $37,490 - $37,320 =$170
Therefore, his tax liability will fall by $170
6. Now he discovers that he is eligible for a $500 tax credit. How much does his tax liability fall due to this credit?
The purpose of the tax credit is to make tax liability reduced dollar by dollar.
Therefore, if he discovers that he is eligible for a $500 tax credit, his tax liability will fall by $500.

Leslie has a box of markers. There are 3 black,
4 red, 2 blue, 1 brown, 2 purple, 2 yellow and 5
green markers. Create a sample space of possible
outcomes for choosing a marker. Is this a simple or compound event?
Answer:
Sample space: {Black, Red, Blue, Brown, Purple, Yellow, Green}
Simple event
Step-by-step explanation:
Sample space is a list of all the possible outcomes.
This is a simple event because you are only doing one event, such as choosing marbles from a bag.
A compound event would be multiple simple events, such as flipping a coin and rolling a dice.

Uma volta inteira na Terra corresponde a uma distância 2πr≅40.000 km. Se um satélite leva 85 minutos para dar uma volta completa ao redor da Terra, qual a sua velocidade média em m/s (metros por segundo)
Answer:
7.8. 10 ^ 3 m / s
Step-by-step explanation:
The computation of the average speed in m/s is shown below:
The average speed equation is
= ΔS ÷ Δt;
As We know that
an entire revolution would be40,000 km
and a satellite takes 85 minutes to complete a revolution,
So,
ΔS = 40,000 km = 40,000,000 m
Δt = 85 min = 5 100 s
Now the average speed is
= 40 000 000 ÷ 5 ÷ 5 100
= 7843.14 m / s
= 7.8. 10 ^ 3 m / s

Select the correct answer from each drop-down menu. Describe the relationship between the area of a circle and its circumference. The (area, diameter, or radius) is (1/3, 1/2, 2, or 3) times the (area, diameter, or radius) times the circumference. (PLEASE HELP ME)
Answer:I got the answer correct because i have to take the test
Step-by-step explanation:
The relation between the area and the circumference is given by:
"The area is 1/2 times the radius times the circumference".
How to find the measures of a circle?
We know that for a circle of radius R we have:
Circumference = P = 2*pi*RArea = A = pi*R^2.If you take the quotient between the area and the circumference, you get:
A/P = (pi*R^2)/(2*pi*R) = R/2
So the area is R/2 times the circumference, or, using the terms given in the list:
"This means that the area is 1/2 times the radius times the circumference"

Given the function f (x) = x² + 8x + 7, what are the zeros of f?
Answer:
x = - 7, x = - 1
Step-by-step explanation:
To find the zeros let f(x) = 0 , that is
x² + 8x + 7 = 0
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 7 and + 1 , since
7 × 1 = + 7 and 7 + 1 = + 8 , then
x² + 8x + 7 = 0
(x + 7)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 1 = 0 ⇒ x = - 1

Find the coordinates of each point after the described reflection. Give the distance between each point and its reflection.
Complete Question:
Find the coordinates of the point after the described reflection. Give the distance between the point and its reflection. R(-5, 8) is reflected across the x-axis _____________.
Answer:
[tex](a)[/tex] [tex]R' = (-5,-8)[/tex]
[tex](b)[/tex] The distance is 16 units
Step-by-step explanation:
Given
[tex]R = (-5,8)[/tex]
Solving (a): Reflection across x-axis
The rule is:
[tex]R(x,y) ==> R(x,-y)[/tex]
So, the reflection of [tex]R = (-5,8)[/tex] is:
[tex]R' = (-5,-8)[/tex]
Solving (b): The distance between R and R'
Distance (d) is calculated as:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
Where:
[tex]R = (-5,8)[/tex] ---- [tex](x_1,y_1)[/tex]
[tex]R' = (-5,-8)[/tex] --- [tex](x_2,y_2)[/tex]
This gives:
[tex]d = \sqrt{(-5- -5)^2 + (-8- 8)^2}[/tex]
[tex]d = \sqrt{(0)^2 + (-16)^2}[/tex]
[tex]d = \sqrt{256}[/tex]
[tex]d = 16[/tex]
The distance is 16 units

Answer:
A triangle with angles measuring 55°, 60°, 65° degrees
Step-by-step explanation:
Two obtuse angles means two angles over 90°
The sum of all angles in a triangle are 180°
90°+90° itself is 180°, so we cant have two angles greater than 90°
Two right angles means 90° and 90° which is 180°, not possible
55°+60°+65° = 180° so it is possible.
Brody has already read 8 books this year before joining a book club,and he plans to read 1 book every month now that he has joined. If Body has read 28 books so far,how many months has he been with his book club?
Answer: 20 months
explanation: You subtract 8 from 28 since 8 is the amount he had before he joined. He also said he planned on reading 1 book per month after joining the club. You want to subtract the 8 since it isn't relevant to the book club books read.
