suppose a large shipment of televisions contained 9% defectives. if a sample of size 393 is selected, what is the probability that the sample proportion will differ from the population proportion by less than 3%? round your answer to four decimal places.
The probability that the sample percentage will deviate from the population proportion by less than 3% is 0.9624, or 96.24%.
We must comprehend the central limit theorem and the normal probability distribution in order to answer this query.
Distribution of Normal Probabilities
The z-score formula can be used to address problems with normal distributions.
The z-score of a measure X in a set with mean and standard deviation can be calculated as follows:
The Z-score calculates how far a measure deviates from the mean by standard deviation. We look at the p-value linked with this Z-score after determining the Z-score by consulting the z-score table. This p-value represents the probability that the measure's value is less than X, or the percentile of X. 1 is subtracted from the p-value, giving us the likelihood that the value of the metric exceeds X.
Imagine that 9% of a huge shipment of televisions were defective.
As a result, the sample size has a p value of 0.09
As a result, n=393
Standard deviation and the mean
u=p= 0.09
s= sqrt(p(1-p)/n)
s=sqrt(0.09*0.91/393)= 0.0144
What is the likelihood that the sample percentage and population proportion will deviate by less than 3%?
The ratio of 0.09 - 0.03 = 0.06 to 0.09 + 0.03 = 0.12 is the result of subtracting the p-value of Z when X = 0.12 from the p-value of Z when X = 0.06.
X = 0.12
By the Central Limit Theorem
Z= x-u/s
Z=2.08 has a p-value of 0.9812
X = 0.06
Z= x-u/s
Z=-2.08 has a p-value of 0.0188
0.9812 - 0.0188 = 0.9624
Therefore, The probability that the sample proportion and population proportion will deviate by less than 3% is 0.9624, or 96.24%.

the hypotenuse of a right triangle is growing at a constant rate of a centimeters per second and one leg is decreasing at a constant rate of b centimeters per second. how fast is the acute angle between the hypotenuse and the other leg changing at the instant when both legs are 1 cm?
The acute angle between the hypotenuse and the other leg changing at the instant when both legs are 1 cm is dθ/dt = -b - a/[tex]\sqrt{2}[/tex] fast.
Differentiation is a process to find the instantaneous rate of change in function based on one of its variables.
The hypotenuse of a right triangle is growing at a constant rate of a centimeters per second
[tex]\frac{dH}{dt} = a[/tex]
One leg is decreasing at a constant rate of b centimeters per second
[tex]\frac{dy}{dt} = -b[/tex]
From the right triangle
sin θ = [tex]\frac{y}{H}[/tex] (y is the perpendicular and H is the hypotenuse)
Differentiate both sides with respect to t
cos θ*dθ/dt = (H*dy/dt - y*dH/dt) / H²
cos θ*dθ/dt = [H(−b)−y(a)] / H²........................(1)
If the both legs are 1 cm.
∴ H= [tex]\sqrt{ 2[/tex],cosθ=sinθ=1/[tex]\sqrt{2}[/tex]
Thus , Equation (1)
cos θ*dθ/dt = [H(−b)−y(a)] / H²
1/√2*dθ/dt = [√2 (−b)−(a)] / 2
dθ/dt = √2 [(√2 (−b)−(a)) / 2]

How to find the perpendicular line?A general linear equation is of the form:
y = m*x + b
Where m is the slope.
Two lines are perpendicular only if the product between the slopes is equal to -1.
Here we start with the line:
y = -x
So the slope is -1.
Then the slope of the perpendicular line m must be:
-1*m = -1
m = -1/-1 = 1
Then the perpendicular line is something like:
y = x + b

The quadratic function f(x) has roots of −4 and 2 and point (1, −5) lies on f(x). What is the equation of f(x)?
f(x) = (x − 2)(x + 4)
f(x) = (x − 2)(x − 4)
f(x) = 4(x − 2)(x + 4)
f(x) = 4(x − 2)(x − 4)
The equation of the quadratic function f(x) is f(x) = (x + 4)(x - 2)
How to determine the equation of f(x)?From the question, we have the following parameters:
Roots = -4 and 2
Point = (1, -5)
Rewrite the given parameters as
Roots: x = -4 and x = 2
Point: (x, y) = (1, -5)
Recall that:
x = -4 and x = 2
This gives
x + 4 = 0 and x - 2 = 0
Multiply the equations
So, we have
y = a(x + 4)(x - 2)
When (x, y) = (1, -5), we have
-5 = a(1 + 4)(1 - 2)
This gives
a = 1
Substitute a = 1 in y = a(x + 4)(x - 2)
y = (x + 4)(x - 2)

Kadeem and Quinn both drive 25 miles. Kadeem drives at a constant speed of 50 miles and hour. Quinn drives at a constant of 75 miles an hour. Who takes longer to drive 25 miles? How much longer?
Kadeem takes 0.5 hours to travel 25 miles, and Quinn 0.33 hours, so Kadeem takes longer.
Who takes longer to drive 25 miles?
Remember the relation:
Speed*time = distance.
Notice that if the distance is fixed, then for a longer speed the time needed will be smaller.
Here we know that:
Kadeem drives at a constant speed of 50mi/h
Quinn drives at a constant speed of 75 mi/h.
Replacing that in the equation:
Kadeem's case:
(50 mi/h)*t = 25mi
t = (25 mi)/(50 mi/h) = 0.5 hours.
Quinn's case:
t = (25mi)/(75 mi/h) = 0.33 hours.

The mortar is 17 times ( 3 / 8 ) tall.
The brick height is equal to 18 times ( 2 + ( 1 / 4 ) ).
I don't know the options, so you have to use those values.
Step-by-step explanation:
DecipheringThe question uses imperial units which are generally bad.
12 inches = 1 feet;
The height of the wall should be written in inches for convenience.
4 feet = 4 * 12 inches;
4 feet = 48 inches;
The wall is short 1 + ( 1 / 8 ) inches short of 4 feet.
48 inches - ( 1 + ( 1 / 8 ) inches ) = 46 + ( 7 / 8 ) inches;
Now that the wall is done let's do the bricks. The height of the bricks is 2 + ( 1 / 4 ) inches and the mortar is ( 3 / 8 ) inches tall. The amount of mortar is the number of bricks - 1 because nobody puts extra mortar on the top of the wall.
Algebralet b;
46 + ( 7 / 8 ) = b( 2 + ( 1 / 4 ) ) + ( b - 1 )( 3 / 8 );
375 / 8 = b( 9 / 4 ) + ( 3 / 8 )b - ( 3 / 8 );
375 / 8 = ( ( 9 / 4 ) + ( 3 / 8 ) )b - ( 3 / 8 );
375 / 8 = ( ( 18 / 8 ) + ( 3 / 8 ) )b - ( 3 / 8 );
375 / 8 = ( 21 / 8 )b - ( 3 / 8 );
Multiply both sides by 8 to get rid of those annoying fractions.
375 = 21b - 3;
Add 3 to both sides.
378 = 21b;
Divide both sides by 21.

A web music store offers two versions of a popular song. The size of the standard version is 2.1 megabytes (MB). The size of the high quality version is 4.7 MB. Yesterday, the high quality version was downloaded twice as often as the standard version. The total size downloaded for the two versions was 3335 MB. How many downloads of the standard version were there?Number of standard version downloads: ?
Answer: 529.3 downloads
Explanation:
Standard version size = 2.1 MB
High quality version = 4.7 MB
The high-quality version was downloaded twice as often as the standard version
H = 2 S
The total size downloaded for the two versions = 3335 MB
H + S = 3335
We have the system:
H = 2 S (a)
H + S = 3335 (b)
Put A into B
(2S ) + S = 3335
3S = 3335
S= 3335/3
S= 1,111.67 MB
Divide the total MB of standard versions by the size of each standard version.
1,111.67 / 2.1 = 529.3 downloads
Yuri bought a new house. The diagram shows the layout of his backyard. Yuri is designing improvements that he wants to make. Yuri plans to fill the patio with concrete, the garden with a special soil mixture, and the remaining areas that surround the hot tub with a wood deck. The table shows the costs associated with each project. How much more will Yuri spend on concrete than on soil and wood? Explain. Click here to view the diagram of Yuri's backyard. Click here to view the table of materials. The area of the patio is yd?, so the cost of concrete is $ The area of the garden is yd?, so the cost of soil is $ The total area of the deck is ft?, so the cost of wood is $1. So, Yuri will spend $ more on concrete than on soil and wood. (Type integers or decimals.) Enter your answer in the edit fields and then click Check Answer. All parts showing
1) Area of patio = 1/2 base x height
Height = 3.1ft
base = 7 + 10 =17 ft
Area = 1/2 x 3.1 x 17
Area of patio = 26.35 square ft
1 yard = 3 ft
1 square yard = 9 square ft
so the area of the patio in yard is
26.35/9 = 2.927777778 square yard
2) Cost of concrete = $10/square yard poured 1/9 yard deep+ $60 delivery fee
for 2.9277777778 square yard it will cost 1/9($10 x 2.9277777778) + $60 =$

Hi can i get help with this precal question please
Using a piecewise function, it is found that:
a. The rule is:
C(w) = 0.75w, 0 ≤ w ≤ 50.C(w) = 0.35w + 10, 51 ≤ w ≤ 75.C(w) = 0.2w + 7, w > 75.b. C(75) = 36.25.
c. C(100) = 27.
d. A practical domain for the function is integer values of w ≥ 0
e. A practical range the function is C(w) ≥ 0.
What is a piecewise-defined function?A piecewise-defined function is a function that has different definitions, depending on the input of the function.
For 0 to 50 wristbands, which is the first definition of the function, the cost is of $0.75 per each wristband, hence the definition is:
C(w) = 0.75w, 0 ≤ w ≤ 50.
From 51 to 75 wristbands, which is the second defition of the function, the cost is of $0.35 per each wristband plus the $10 shipping fee, hence:
C(w) = 0.35w + 10, 51 ≤ w ≤ 75.
For more than 75 wristbands, which is the third definition of the function, the cost is of $0.2 per wristband plus the $7 shipping fee, hence:
C(w) = 0.2w + 7, w > 75.
The numeric values are as follows:
C(75) = 0.35 x 75 + 10 = 36.25.C(100) = 0.2(100) + 7 = 27.The domain and the range of the function are as follows:
Domain -> input values -> number of wristbands, which is a countable amount, hence integer numbers of 0 or greater.Range -> Output values -> cost of purchasing w wristbands, real values greater than 0.More can be learned about piecewise functions at https://brainly.com/question/19358926

Answer
A) f(w) = 80w + 30
B) w represents the number of weeks and f(w) the number of flowers that bloomed
C) 2830 flowers
Step-by-step explanation
A) To find the function f, which represents the number of flowers that bloomed, as a function of w, the number of weeks, we have to evaluate f(s) with s = s(w) = 40w, as follows:
[tex]\begin{gathered} f(s)=2s+30 \\ \text{ Substituting }s=s(w), \\ f(s(w))=2s(w)+30 \\ \text{ Substituting }s(w)=40w \\ f(s(w))=2\cdot40w+30 \\ f(w)=80w+30 \end{gathered}[/tex]B) w represents the number of weeks and f(w) the number of flowers that bloomed, like before.
C) Substituting w = 35 weeks into f(w), we get:
[tex]\begin{gathered} f(w)=80(35)+30 \\ f(w)=2800+30 \\ f(w)=2830\text{ flowers} \end{gathered}[/tex]What values of x and y make △QRS≅△FDE?
What is the transformation of both y=-√-4x, and y=√-4x? I've looked everywhere to try and find it, but the internet is not helping!
The transformation that relates the two functions:
f(x) = y = -√(-4x)
g(x) = y = √(-4x)
Is a reflection across the x-axis.
What is the transformation applied?
We define a reflection across the x-axis as a transformation that does a "vertical reflection" along the line y = 0 (which is the x-axis).
For a function f(x), a reflection across the x-axis generaste the new function g(x) that can be written as:
g(x) = -f(x).
In this case the original function is:
f(x) = y = -√(-4x)
And the transformed function is:
g(x) = y = √(-4x)
You can see that the only difference is the sign, such that we can write:
g(x) = -f(x) = -(-√(-4x)) = √(-4x)
So we conclude that the transformation is a reflection across the x-axis.

The diagonals of a rectangle are congruent, so RT = SU, that is
3x + 8 = 6x - 4 (subtract 4x from both sides)
3x + 8 = 6x - 4
Subtract 8 from both sides 3x + 8 - 8 = 6x - 4 - 8
Simplifying the above equation, we get
3x = 6x-12
Subtract 6x from both sides 3x - 6x = 6x - 12 - 6x
Simplifying the above equation, we get
-3x = -12
Divide both sides by -3
[tex]$\frac{-3 x}{-3}=\frac{-12}{-3}[/tex]
x = 4
Then, R T= 3x + 8 = 3(4) + 8 = 20
The diagonals bisect each other, then
RV = 0.5 × 20 = 10
∠ RVU = ∠ SVT = 54° ( vertical angles)
RV = UV ( diagonals are congruent and bisect each other)
Then Δ RVU is isosceles with base angles congruent, then
∠ VUR =[tex]$\frac{180-48}{2}[/tex] = 66°.
In the rectangle, RV = 3x+8, SV = 6x-4, and ∠ VRS = 54° then the value of x is 4 and ∠ VUR is 66°.
