Answer:

Step-by-step explanation:

if the price of the apartment is 140,000 dollars

lets find out how much is 1%

140,000/100=1400

42,000/1400=30  

42,000 is 30% of the apt price

The mixed fraction [tex]4\frac{7}{500}[/tex] can be represent as 401%.

What is fraction?

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

The number of parts into which the whole has been divided is shown by the denominator. It is positioned in the fraction's lower portion, below the fractional bar.How many sections of the fraction are displayed or chosen is shown in the numerator. It is positioned above the fractional bar in the upper portion of the fraction.

Given:

Fraction : 4 7/500

Now, writing the fraction in normal fraction form

= 4 7/500

= 2007/500

Now, to convert into percent

= 2007/ 500 x 100

= 2007/ 5

= 401%

Answer:

y = (1/2) x - 2

Step-by-step explanation:

Let us consider the points (- 2, - 3) & (0, - 2)

Equation of line in two point form is given as:

[y-(-3)]/[-3-(-2)] = [x - (-2)]/[-2 - 0]

(y + 3)/(-3 +2) = (x + 2)/ (-2)

(y + 3)/(-1) = (x + 2)/(-2)

(y + 3)/(1) = (x + 2)/(2)

2(y + 3) = (x + 2)

2y + 6 = x + 2

2y = x + 2 - 6

2y = x - 4

y = (1/2) x - 2

35- 8.75= 26.25  (subtract that from the original to find the discount price)

Fewer young people are driving. In , of people under years old who were eligible had a driver's license. Bloomberg reported that percentage had dropped to in . Suppose these results are based on a random sample of people under years old who were eligible to have a driver's license in and again in . a. At confidence, what is the margin of error and the interval estimate of the number of eligible people under years old who had a driver's license in ?

Answers

The margin of error is 0.027 and the interval estimate at 95% confidence interval is 0.612 to 0.666

How to calculate the margin of error and the interval estimate

From the question, we have the following parameters that can be used in our computation:

Proportion, p = 63.9%

Sample size, n = 1200

The margin of error can be calculated using:

E = z * √((p * (1 - p))/n)

Where

z = 1.96 i.e. z-score at 95% CI

Substitute the known values in the above equation, so, we have the following representation

E = 1.96 * √((0.639 * (1 - 0.639))/1200)

Evaluate

E = 0.027

The interval estimate is calculated as

I = p ± E

So, we have

I = 0.639 ± 0.027

Evaluate

I = 0.612 to 0.666

Hence, the interval estimate is 0.612 to 0.666

The height in feet (h) of the ball t seconds after it is released can

Find the time, in seconds, passed before the ball hits the ground
(let h = 0).*
*PLEASE SHOW WORKK

Answers

Step-by-step explanation:

h = -16t² + 10t + 6

When h = 0, -16t² + 10t + 6 = 0.

=> -8t² + 5t + 3 = 0

=> (-8t - 3)(t - 1) = 0

=> t = 1 or t = -3/8 (rejected as time cannot be negative)

Hence 1 second passed before the ball hits the ground.

Answer:

The 95% confidence interval  is  [tex] 17.932  <  \mu <  20  + 22.068[/tex]

Step-by-step explanation:

From the question we are told that

  The population standard deviation is  [tex]\sigma =7 \ inches[/tex]

  The sample size is  n  =  20

  The sample mean is  [tex]\= x = 20[/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{7 }{\sqrt{20} }[/tex]

=>    [tex]E = 2.068[/tex]        

Generally 95% confidence interval is mathematically represented as  

      [tex]\= x -E <  \mu <  \=x  +E[/tex]

=>     [tex] 20  - 2.068  <  \mu <  20  + 2.068[/tex]

=>     [tex] 17.932  <  \mu <  20  + 22.068[/tex]
