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.

Of the 1250 students registered at the local high school, 30% of them did not vote during the student body elections. How many students did not vote?
A) 350
B) 425
C) 365
D) 375
Answer: D) 375
Step-by-step explanation:
We will find 30% of 1,250 since 30% did not vote. A percent divided by 100 becomes a decimal.
30% / 100 = 0.3
1,250 * 0.3 = 375
D) 375 students did not vote.

lnx=-3
the answer in the textbook says it becomes x=e^-3 which I agree with, but then it gives 0.05 as the answer to solving it, I just don't understand how they found 0.05. Can anyone explain how to get 0.05 from x=e^-3?
Answer:
because It's rounded to the nearest hundred place
Step-by-step explanation:
Given equation:
[tex] \ln(x ) = - 3[/tex]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]
1/e³ is approximately 0.0497870684..... , rounding it to the nearest hundred place would be 0.05 which is the same answer as your textbook .

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.

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

Answer:
x = 4
Step-by-step explanation:
here's my work :D
Answer:
x = 4
Step-by-step explanation:
3/4(x + 8) = 9 <== convert the fraction to a decimal
0.75(x + 8) = 9 <== distribute
0.75x + 6 = 9 <== subtract 6 from both sides
- 6 - 6
0.75x = 3 <== divide both sides by 0.75 to isolate the variable
/0.75 /0.75

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)
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).
