Step-by-step explanation: 1:2 is like half of the whole so basically what i mean is the first number has to be half of the second number for example 2:4 or 4:8

Answer:

No

Step-by-step explanation:

If these ratios were equivalent the second would read 14:24. So if the first ratio was 1:3 the second would read 14:42.

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

Answer:

No

Step-by-step explanation:

since the magnitude of xy ≠ zw,

|x-y| = xy = |52-121|= 69, |z-w| = zw = |-21-25| = 46

69 ≠ 46

Answer:

addition property of equality, subtraction property of equality, simplified, division property of equality and simplified.

Step-by-step explanation:

Answer:

1  given

2  Combining like terms  

3    addition property of equality

4   simplification

5   division property of equality

6   simplification

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.

Answer:

1

Step-by-step explanation:

The equation would look like this: ¾ ÷ ¾

When dividing fractions, you always flip the second one to receive the reciprocal, so the equation now looks like this: ¾ ÷ 4/3

If you cross simplify, the answer will end up being 1.

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

Complete Question

Answer:

a

  [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]  

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".

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

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.

Answer: Choice A

Explanation:

The sequence converges to a nonzero value, so as n gets very large, the partial sums will grow forever (since we're effectively adding at least 1 to each term regardless how large n gets)

The reason why [tex]s_n[/tex] approaches 1 is because the 1/n term goes to 0 when n gets very large.

7 is prime so the least common denominator is 7 times 2 times 5 which is 70.
