Step-by-step explanation:
In step 2, the like terms of x and x were combined and simplified to -2x.
In step 3, adding 7 to both sides of the equation to isolate the variable term is justified by the addition property of equality.
In step 4, the constants are combined on each side for simplification.
In step 5, dividing both sides of the equation by -2 to isolate the variable is justified by the division property of equality.
In step 6, simplification results in the solution of x = 4.

You and your friend start a typing class at the same time. You measure your speed weekly in words per minute (WPM) on a class chart. If the trend continues, after how many weeks can you expect to type as quickly as your friend? What will that WPM be?
A. 6 weeks;28 WPM
B. 6 weeks; 31 WPM
C. 7 weeks;31 WPM
D. 7weeks;34 WPM
Answers
Answer:
The correct answer is 7 weeks 34 WPM
Step-by-step explanation:
The number of weeks and words typed will be D. 7weeks;34 WPM
Based on the information given, the formula to calculate my words per minutes = 13 + 3n
The formula to calculate my friend's words per minutes = 20 + 2n
Therefore, we'll equate both equations together and this will be:
13 + 3n = 20 + 2n
Collect like terms
3n - 2n = 20 - 13
n = 7.
Therefore, the WPM will be:
= 13 + 3n
= 13 + 3(7)
= 13 + 21
= 34
The number of weeks and words typed will be 7weeks;34 WPM

in 3 1/2 months John collected a debt of $70.00. What was the average amount of debt John collected per month?
Answers
Answer:
The average amount of debt John collected per month is $20/ month
Step-by-step explanation:
Given;
total debt collected by John, = $70.00
total number of months, = 3 1/2 months = 7/2 months
The average amount of debt John collected per month is given by;
[tex]Average \ amount \ per \ month = \frac{Total \ amount \ of \ debt}{total \ number \ of \ months} \\\\Average \ amount \ per \ month =\frac{70}{1} *(\frac{2}{7} )\\\\Average \ amount \ per \ month = \$20 \ / month[/tex]
Therefore, the average amount of debt John collected per month is $20/ month

Answer:

[tex]SE = 0.66}[/tex]
b
[tex] -3.29 < \mu_1 - \mu_2 < -0.70[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 60
The first sample mean is [tex]\= x _1 = 8[/tex]
The second sample mean is [tex]\= x _2 = 10[/tex]
The first variance is [tex]v_1 = 0.25[/tex]
The first variance is [tex]v_2 = 0.55[/tex]
Given that the confidence level is 95% then the level of significance is 5% = 0.05
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 first standard deviation is
[tex]\sigma_1 = \sqrt{v_1}[/tex]
=> [tex]\sigma_1 = \sqrt{0.25}[/tex]
=> [tex]\sigma_1 = 0.5[/tex]
Generally the second standard deviation is
[tex]\sigma_2 = \sqrt{v_2}[/tex]
=> [tex]\sigma_2 = \sqrt{0.55}[/tex]
=> [tex]\sigma_2 = 0.742 [/tex]
Generally the first standard error is
[tex]SE_1 = \frac{\sigma_1}{\sqrt{n} }[/tex]
[tex]SE_1 = \frac{0.5}{\sqrt{60} }[/tex]
[tex]SE_1 = 0.06[/tex]
Generally the second standard error is
[tex]SE_2 = \frac{\sigma_2}{\sqrt{n} }[/tex]
[tex]SE_2 = \frac{0.742}{\sqrt{60} }[/tex]
[tex]SE_2 = 0.09[/tex]
Generally the standard error of the difference between their mean scores is mathematically represented as
[tex]SE = \sqrt{SE_1^2 + SE_2^2 }[/tex]
=> [tex]SE = \sqrt{0.06^2 +0.09^2 }[/tex]
=> [tex]SE = 0.66}[/tex]
Generally 95% confidence interval is mathematically represented as
[tex](\= x_1 -\= x_2) -(Z_{\frac{\alpha }{2} } * SE) < \mu_1 - \mu_2 < (\= x_1 -\= x_2) +(Z_{\frac{\alpha }{2} } * SE)[/tex]
=> [tex](8 -10) -(1.96 * 0.66) < \mu_1 - \mu_2 < (8-10) +(Z_{\frac{\alpha }{2} } * 0.66)[/tex]
=> [tex] -3.29 < \mu_1 - \mu_2 < -0.70[/tex]

Which trigonometric ratio does this represent?
Answers
Answer:
Step-by-step explanation:
From the picture attached,
From ΔABC,
m∠B = 180° - (m∠C + m∠A)
= 180° - (90° + 32°)
= 180° - 122°
= 38°
Now we have to find the trigonometric ratio of BC and AB from ΔABC,
Since, sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
sin(32°) = [tex]\frac{BC}{AB}[/tex]
[tex]\frac{BC}{AB}=0.53[/tex]
Therefore, ratio of BC and AB represents the "sine of angle A".

Alright, -3r + 4(-3r + 2) = 53 how do I break it down and solve??
Answers
Answer:
r = -3
Step-by-step explanation:
-3r + 4(-3r +2) = 53
-3r + -12r + 8 = 53
-8 -8
-3r + -12r = 45
-15r = 45
Divide both sides by -15 to get
r = -3
Answer:
r = -3
Step-by-step explanation:
expand 4(-3r+2)
= -12r+8
add similar variables
= -15r+8=53
subtract 8 from both sides
= -15r+8-8=53-8
simplify
= -15r=45
divide 45 by -15
= -3

Determine the variables tested in each of the following experiments. If applicable, determine and identify any positive or negative controls. A study is being done to test the effects of habitat space on the size of fish populations. Different sized aquariums are set up with six goldfish in each one. Over a period of six months, the fish are fed the same type and amount of food. The aquariums are equally maintained and cleaned throughout the experiment. The temperature of the water is kept constant. At the end of the experiment, the number of surviving fish are surveyed. A. Independent Variable: B. Dependent Variable: C. Controls:
Answers
Answer:
Independent Variable- size of aquariums
Dependent variable - number of surviving fish
Controls: nil
Step-by-step explanation:
In every experiment, the independent variable is manipulated and its effect on the dependent variable is observed as certain factors are kept constant.
In this study, the independent variable is the size of the aquariums. As this factor is manipulated, the number of surviving fish (dependent variable) changed accordingly. There was no mention of a control group in the experiment.
However, temperature, amount of food and type of food were held constant for all the experimental groups.
