The maker of a cell phone screen protector would like to estimate the proportion of customers who file a warranty claim. To do so, they select a random sample of 200 customers and determine that the 96% confidence interval for the true proportion of customers who file a warranty claim to be 0. 15 to 0. 28. Which of these statements is a correct interpretation of the confidence level?


Approximately 96% of customers file a warranty claim.


The cell phone screen protector maker can be 96% confident that the interval from 0. 15 to 0. 28 captures true proportion of customers who file a warranty claim.


If many random samples of size 200 are selected from the population of all customers, approximately 96% of the sample proportions of customers who file a warranty claim will be between 0. 15 and 0. 28.


If many random samples of size 200 are selected from the population of all customers, about 96% of the intervals constructed from the samples would capture the true proportion of customers who file a warranty claim

Answers

Answer 1

According to the interpretation of the confidence interval, the correct statement is:

The cell phone screen protector maker can be 96% confident that the interval from 0.15 to 0.28 captures true proportion of customers who file a warranty claim.

What is the interpretation of a x% confidence interval?

It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.

In this problem, we have a 96% confidence interval between 0.15 and 0.28, hence we are 96% confident that the population proportion is between these values, and the correct option is:

The cell phone screen protector maker can be 96% confident that the interval from 0.15 to 0.28 captures true proportion of customers who file a warranty claim.

Check the picture below.

so the deck is a 72x52 rectangular area, and the pool is simply two semicircles with a rectangle, as you see in the picture, we can put both semi-circles and make one circle with their area, so both together are really the area of a circle whose diameter is 29, and thus its radius is half that or 14.5.

Now, the area Belvedere is going to seal is really the "shaded" or bricked area, if we take the area of the whole deck, including the pool, and then get the area of the pool and subtract it from that of the deck's, what's leftover, is the area that wasn't subtracted, namely the "shaded" area.

Which expression can be subtracted from the area of the rectangle to find the area of parallelogram rstu? 2 (18 4) one-half (18 4) (18 4) (18 - 4)

Answers

The expression can be subtracted from the area of the rectangle to give the area of the parallelogram RSTU (18+4).

What is the area of the rectangle?

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

The coordinates of parallelogram RSTU are

R(-4, -3), S(-5, 1), T(4, 3), U(5, -1)

The lengths of the sides are

RS = 4.1231

RT = 10

ST = 9.2195

SU = 10.198

TU = 4.1231

UR = 9.2195

Therefore, by definition of a parallelogram, we have;

RS║TU and ST║UR

The slope of RS = (1 - (-3))/(-5 - (-4)) = -4

The slope of ST = (3 - 1)/(4 - (-5)) = 2/9

The equation of the line perpendicular to ST is

y - 1 = -9/2×(x - (-5))

y = -9x/2 - 43/2

The equation of RS = y - (-3) = 1/4×(x - (-4)) = x/4 + 1

y = x/4 - 2

The point where the two lines meet

-9x/2 - 43/2  =  x/4 - 2

x = -78/19

y = -115/38

The length of the side of the rectangle = 4.1245

The excess width of the rectangle = 0.1085

The expression can be subtracted from the area of the rectangle to give the area of the parallelogram RSTU (18+4).

Answer:

because It's rounded to the nearest hundred place

Step-by-step explanation:

Given equation:

recall that,

[tex] \ln(a ) = b \iff {e}^{b} = a[/tex]

remember, In is natural logarithm which is actually nothing but common logarithm with the base euler's number (e) . anyway rewriting lnx=-3 yields:

[tex] \ln( x ) = - 3\\ \iff {e}^{ - 3} = \frac{1}{ {e}^{3} } [/tex]

The price of each game is the same, and the price of each controller is the same. Which system of equations can be used to find the price, in dollars, of each game, g, and each controller, c

Answers

The linear system with two variables is used to find the price. The price of each game is $60 and the price of each controller is $30.

What is the linear system?

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.

A customer at a video game store pays $420 for 6 games and 2 controllers.

A second customer pays $180 less than the first customer for 2 games and 4 controllers.

The price of each game is the same, and the price of each controller is the same.

Let x be the price of games and y be the price of the controller. Then the equations will be

6x + 2y = 420  ...1

2x +  4y = 240  ...2

By solving the equations 1 and 2, then we have

x = 60 and y = 30
