A number is doubled and then increased by nine. The result is ninety- Three. What is the original number?

Answers

Answer 1

Answer:

42

Step-by-step explanation:

First you subtract 93 by 9. You get 84. Then you divide it by 2. Which is your answer, 42.

This can be represented as:

93=2x+9

First subtract 9 from both sides

84=2x

Then divide by 2 on both sides

42=x

The measure of angle 7 in the system created by two non-parallel lines is 108°.

What are supplementary angles?

The supplementary angles are defined as when pairing of angles addition to 180° then they are called supplementary angles. There are two types of supplementary angles.

A line that is crossed by a non-parallel line produces four pairs of extra angles, according to geometry. If and only if two angles are close to one another and the sum of their measures is 180 degrees, then those angles are supplementary.

Then, m ∠ 6 + m ∠ 7 = 180° = 72° + m ∠ 7 = 180°.

So, m ∠ 7 = 108°.

Therefore, the measure of angle 7 in the system created by two non-parallel lines is 108°.

For employees at a large company, the mean number of overtime hours worked each week is 9.2 hours with a population standard deviation of 1.6 hours. A random sample of 49 employees was taken and the probability that the mean number of overtime hours will be at least 9.3 hours was determined. Was the probability a Left-tail, Right -tail or Interval Probability? Use a calculator to find the probability that the mean overtime hours for the sample will be at least 9.3 hours. Select the two correct answers that apply below.

Answers

Complete Question

Answer:

The  probability is  Right- tailed

The mean overtime hours for the sample will be at least 9.3 hours is

    [tex]P(X \ge 9.3 ) = 0.3333[/tex]

Step-by-step explanation:

From the question we are told that

    The mean is  [tex]\mu = 9.2 \ hours[/tex]

    The  standard deviation is  [tex]\sigma = 1.6 \ hours[/tex]

    The sample size is n  =  49

      The sample  mean is  [tex]\= x = 9.3[/tex]

Generally the standard error of the mean is mathematically represented as

      [tex]\sigma_{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]

=>   [tex]\sigma_{\= x} = \frac{1.6 }{\sqrt{49} }[/tex]

=>    [tex]\sigma_{\= x} = 0.22857[/tex]

This is a right -tailed probability because the sample mean is greater than the        population mean

 Generally  the probability that the mean overtime hours for the sample will be at least 9.3 hours is mathematically represented as  

           [tex]P(X \ge 9.3 ) =1 - P(X < 9.3 )[/tex]

So

           [tex]P(X < 9.3 ) = P( \frac{ X - \mu }{ \sigma_{\= x }} < \frac{ 9.3 - 9.2 }{ 0.22857} )[/tex]

Here   [tex]\frac{X - \mu }{\sigma _{\= x}} = Z[/tex]

           [tex]P(X < 9.3 ) = P( Z < 0.43750)[/tex]

From the z-table  

            [tex]P(X < 9.3 ) = P( Z < 0.43750) = 0.667[/tex]

So

   [tex]P(X \ge 9.3 ) =1 - 0.667[/tex]

   [tex]P(X \ge 9.3 ) = 0.3333[/tex]

Are rent rates influenced by the student population in a college town? Let rent be the average monthly rent paid on rental units in a college town in the United States.

(ii) What signs do you expect for b1 and b2? (iii) The equation estimated using 1990 data from RENTAL for 64 college towns is

Answers

Step-by-step explanation:

The regression equation is correctly written as:

log(rent) = β₀+β₁log(pop)+β₂log(avginc)+β₃pctstu+μ

1. this question requires us to State the null hypothesis that size of the student body relative to the population has no ceteris paribus effect on monthly rents.

null hypothesis

H₀ : β₃ = 0 (no effect exists)

alternative that there is an effect.

H₁ : β ≠ 0

2.

Due to increased demand when population is increased, the higher the number of people living in the city then there is a great likelihood that rent would increase. β1 will therefore be positive, all things being equal.

as average income rises, so also would rent as the people would have more money and therefore there would be increased demand for housing. This increase in demand would then cause a surge in the price of rent.  β₂ would therefore be positive .

Your grandmother gave you ₱1000 to start a college book fund. She also promised to add another ₱200 each month, if you add ₱50 monthly. Which rule generates a sequence of the monthly amounts in your college book fund? answer​

Answers

Answer:

A= ₱1000 + t( ₱250) ------where t is the time in months

Step-by-step explanation:

The principal amount ,P, is given as : ₱1000----- P=₱1000 ------equation (i)

Additional amounts to be added by grandmother = ₱200 monthly

Amount expected to add monthly =  ₱50

Additional amounts in total added monthly = ₱200 + ₱50=₱250

Monthly amounts ,A, in the fund after the first month, t =1 month will be:

A=P + ₱250= ₱1000 + 1( ₱250) ------where t= 1, amount at end of month 1

A=P +₱250= ₱1000 + 2( ₱250)--------where t=2,  amount at end of month 2

A=P +₱250= ₱1000 + 3( ₱250)---------where t=3, amount at end of month 3

A=P +₱250= ₱1000 + 4( ₱250)--------where t=4, amount at end of month 4

From the breakdown above of 4 months, the general equation of monthly amounts will be;

A= ₱1000 + t( ₱250) ------where t is the time in months

A sequence of the monthly amounts in your college book fund is given by the equation (A = 1000 + 250t) and this can be determined by forming the linear equation with the help of the given data.

Given :

Your grandmother gave you ₱1000 to start a college book fund. She also promised to add another ₱200 each month, if you add ₱50 monthly.

The following steps can be used to determine a sequence of the monthly amounts in your college book fund:

Step 1 - Given that the principal amount is ₱1000 which is given by the grandmother.

Step 2 - Additional amount is given by grandmother is ₱200 and each month ₱50 is added. So, the total additional amount each month is:

= 200 + 50

= ₱250

Step 3 - Let 't' be the number of months. So, the linear equation becomes:

A = 1000 + 250(t)

where A is the total amount and t is the time in months.

A sequence of the monthly amounts in your college book fund is given by the equation (A = 1000 + 250t)

Given,

The function is [tex]y=6.4 cos(\frac{\pi x}{26})+12[/tex]

For minimum hours of sunlight, [tex]cos(\frac{\pi x}{26})[/tex]  should have the lowest value, that is -1 for [tex]x=26[/tex] {because [tex]cos (\pi )=-1[/tex] is the lowest value of cosine function}

The difference between the areas of the figures is less than 6.

Answers

Answer:

|24 - (2x - 6)| < 6

x > 12 or x < 18 (12 < x < 18)

Step-by-step explanation:

Area of the triangle = ½*base*height = ½*8*6 = 4*6 = 24 unit²

Area of rectangle = length * width = (x - 3) * 2 = (2x - 6) unit²

Difference in their areas is given as less than 6. This can be represented as an absolute value of inequality as shown below:

|24 - (2x - 6)| < 6

Solve to find the solution of the inequality by splitting into two as follows:

24 - (2x - 6) < 6 OR 24 - (2x - 6) > -6

Solve for each

24 - 2x + 6 < 6

30 - 2x < 6

Subtract 30 from both sides

-2x < 6 - 30

-2x < -24

Divide both sides by -2. < will change to >, since we are dividing by a negative number.

x > 12

Or

24 - (2x - 6) > -6

24 - 2x + 6 > -6

30 - 2x > -6

Subtract 30 from both sides

-2x > -6 - 30

-2x > -36

Divide both sides by -2

x < 18

The solution of the inequality is x > 12 or x < 18

Or can be written as: 12 < x < 18
