According to a 2009 Reader's Digest article, people throw away approximately 90% of what they buy at the grocery store. Assume this is the true proportion and you plan to randomly survey 100 grocery shoppers to investigate their behavior.
Required:
What is the probability that the sample proportion exceeds 0.84?
Answers
Answer:
0.9495
Step-by-step explanation:
We are given;
Population proportion; p = 90% = 0.9
Sample size; n = 100
Sample Proportion; p^ = 0.84
Formula to find the probability that sample proportion exceeds 0.84 is;
Z = P(p^ > 0.84) = (p - p^)/√(p^(1 - p^)/n)
Z = (0.84 - 0.9)/√(0.84(1 - 0.84)/100)
Z = -0.06/0.03666
Z = -1.64
From online z-score calculator attached, the probability is;
P(x>Z) = 0.9495

A common aspect ratio for computer screens today is width : height = 16 : 9. The advertised size of a screen is given by the measure of its diagonal. Measure the width, height, and diagonal of at least three screens (computers, tablets, phones) in your home. Are they similar? How do you know? Are any of your screens congruent? If so, what postulates prove it? List your measurements and describe your findings carefully.
Please follow these guidelines for your discussion posts:
Write at least 150–300 words.
Answers
A common aspect ratio for computer screens is 16:9, which means that for every 16 units of width, there are 9 units of height. This aspect ratio is also used on many televisions and mobile devices.
How to explain the ratio?If a screen has an aspect ratio of 16:9, the width and height will be similar on all screens with this aspect ratio. However, the diagonal measurement will vary depending on the size of the screen.
Congruent screens are two or more screens that have the same dimensions. Two screens are congruent if and only if corresponding sides are equal and corresponding angles are equal. This can be proven using the postulates of congruence, such as the SSS (Side-Side-Side) postulate or the SAS (Side-Angle-Side) postulate.

Measure the shape yourself and follow the explanation.
Step-by-step explanation:
Measure each side of the Triangles with your ruler. Record it.
For example,
I measured and got 3cm, 3.5cm, 3.5cm.
Multiply by scale factor r 2.
for example, 3cm × 2 = 6cm
3.5cm × 2 = 7.0cm
3.5cm × 2 = 7.0cm
Use your pencil to draw your new numbers to form the new Triangle.
As for the second shape, measure each four sides using ruler
for example, I measured and had 4cm, 6cm, 4cm, 6m.
Multiply by scale factor r 2.
for example, 4cm × 1/4 = 1 cm
6cm × 1/4 = 1.5cm
4cm × 1/4 = 1 cm
6cm × 1/4 = 1.5cm
Use your ruler to measure 1cm, 1.5cm, 1cm and 1.5cm, then to draw your new shape

A linear equation illustration is what?Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, and 3x - y + z = 3. The meaning of linear equations, the normal form for linear equations involving one element, two variables, or three variables, and instances of each will all be covered in detail in this essay.
Let r and y stand for the quantity of red and yellow passes sold, respectively.
We know that the total number of tickets sold was 1,032, so we can write the equation:
r + y = 1,032
We also know that the total sales was $979, and that the red tickets were $1.25 each and the yellow tickets were $0.75 each. Therefore, we can write the equation:
1.25r + 0.75y = 979
Therefore, the pair of linear equations that can be used to find the number of red tickets sold is:
r + y = 1,032
1.25r + 0.75y = 979

Rotations of shapes refer to the transformation of a shape around a fixed point called the center of rotation. This transformation involves rotating the shape by a certain angle while keeping the shape's size and shape consistent.
The angle of rotation determines how much the shape is rotated. It is measured in degrees or radians.
Properties of Rotations:
Rotations preserve the size and shape of the original shape.

Answers
Proof:
Let's start of by solving for the length of AC, which is just the sum of lengths AB and BC, which is 10 + 3 = 13 units.
Because of our second given, AC ≅ EG, we know that EG is also 13 units in length. Also, from our first given, BC ≅ EF, we know that EF is 3 units.
We also know that the length of EG is the sum of lengths EF and FG so we can write the equation
EG = EF + FG
13 = 3 + FG
FG = 10 meaning FG is 10 units

Answers
Let's begin by listing out the given information:
Initiation fee = $21.25
Rent = $6.25 /DVD
The equation to show the total amount, D, Charlotte paid to rent x DVDs is given:
\(D=21.25+\text{6}.25x\)If she paid a total of $83.75, how many DVDs did she rent is given by:
\(\begin{gathered} D=\text{21}.25+6.25x \\ D=83.75 \\ 83.75=21.25+6.25x \\ \text{Subtract ''21.25'' from both sides, we have:} \\ 83.75-21.25=6.25x \\ 62.5=6.25x\Rightarrow6.25x=62.5 \\ 6.25x=62.5 \\ \text{Divide both sides by ''6.25'', we have}\colon \\ x=\frac{62.5}{6.25}=10 \\ x=10 \end{gathered}\)Therefore, Charlotte rented 10 DVDs
