The perimeter of a rectangular price tag is 28 centimeters. The price tag is 4 centimeters tall

Answer:

0.101

Step-by-step explanation:

Given that :

Standard deviation, s = 0.2

Sample variance, s² = 0.0653

Sample size, n = 10

Population variance = σ² = 0.04

We use the Chi square distribution :

(n - 1)s² / σ²

For P(s² ≥ 0.065)

(n - 1)s² / σ² = (10 - 1)*0.0653 / 0.04

(n - 1)s² / σ² = 0.585 / 0.04 = 14.625

P(s² ≥ 14.625) = 0.101 ( chi squee calculator).

Answer: 13

Step-by-step explanation:

4x+3y=-5 solve x :    

4x = -3y + -5           | -3y

1x = -0.75y + -1.25  | : 4

-3x + 7y = 13 solve x :

-3x + 7y = 13              | -7y

-3x = -7y = 13             | : (-3)

Equalization Method Solution: -0.75y+-1.25=2.333y+-4.333

-0, 75y - 1,25 = 2,333y - 4, 333 solve y:

-0, 75y - 1,25 = 2,333y -4, 333    | -2,333y

-3, 083y - 1,25 = -4,333               | + 1, 25

-3. 083y = -3,088                         | : (-3, 083)

y = 1

Plug y = 1 into the equation 4x + 3y = -5 :

4x + 3 · 1           | Multiply 3 with 1

4x + 3 = -5        | -3

4x = -8              | : 4

x = -2

So the solution is:

Answer:

88.25

Step-by-step explanation:

Answer:

Step-by-step explanation:

You want the slope, y-intercept, and equation for a line that passes through the points (2, -2) and (8, 1).

The slope formula is used to find the slope:

  m = (y2 -y1)/(x2 -x1)

  m = (1 -(-2))/(8 -2) = 3/6 = 1/2

The slope-intercept equation can be rearranged to give the y-intercept:

  b = y - mx

  b = 1 -(1/2)(8) = 1 -4 = -3 . . . . . . using (x, y) = (8, 1)

The slope-intercept form equation is ...

  y = mx +b . . . . . . where m is the slope, and b is the y-intercept

Using the found values, the equation is ...

Answer:

The 48-ounce carton is the cheapest

Step-by-step explanation:

The question gives us the prices of different sizes of bottles of orange juice. It then asks us to calculate the price per ounce for each size and to find which size is the cheapest.

In order to calculate the price per ounce for each size, we have to divide the price of each size by its size:

• 8-ounce bottle:    \(\mathrm{\frac{\$ 0.90}{8 \ oz}}\) = $0.113 / oz

• 18-ounce bottle:  \(\mathrm{\frac{\$ 1.50}{18 \ oz}}\) = $0.083 / oz

• 48-ounce bottle:  \(\mathrm{\frac{\$ 2.50}{48 \ oz}}\) = $0.052 / oz

• 64-ounce bottle:  \(\mathrm{\frac{\$ 3.75}{64 \ oz}}\) = $0.059/ oz

As we can see from the calculation above, the price per ounce of the 48-ounce carton is the lowest, at $0.052 / oz.

Step-by-step explanation:

p=2l+2w

p=2(2w)+2w

p=4w+2w

p=6w

p=90

90=6w

15=w

In order to calculate the remainder of this division, we can use the remainder theorem.

This theorem states that when dividing p(x) by q(x), and q(x) has a zero x = k, the remainder of the division is given by r = p(k).

Since the division is by the polynomial x - 1 and its zero is x = 1, let's calculate the value of p(1), which will be the remainder of the division:

Therefore the remainder of the division is 3.

While Piaget, Vygotsky, and Bruner have different perspectives on how learning occurs, they all emphasize the active role of the learner in constructing knowledge and the importance of social interaction and cultural influences in the learning process.

Here's a three-column table evaluating how learning takes place according to Piaget, Vygotsky, and Bruner:

Theorist Approach to Learning Key Concepts

Piaget Constructivism 1. Schema: Individuals actively construct their knowledge through assimilation and accommodation, organizing information into mental structures called schemas. 2. Stages of Development: Learning occurs through cognitive development stages, from sensorimotor to formal operational, where individuals progressively acquire more complex mental abilities. 3. Active Exploration: Children learn best through hands-on exploration and interactions with the physical world.

Vygotsky Sociocultural Theory 1. Zone of Proximal Development (ZPD): Learning takes place within the gap between a learner's actual developmental level and their potential level with guidance from a more knowledgeable other. 2. Social Interaction: Learning is facilitated through social interactions with peers and adults, such as cooperative learning and scaffolding. 3. Cultural Tools: The use of language, symbols, and cultural artifacts plays a central role in cognitive development and learning.

Bruner Constructivism 1. Scaffolding: Instruction should provide support and guidance tailored to the learner's current abilities to help them progress to higher levels of understanding. 2. Discovery Learning: Learners construct knowledge by actively exploring and discovering concepts and relationships on their own. 3. Spiral Curriculum: Learning is organized in a spiral manner, revisiting key concepts and building upon previous knowledge in a progressive and interconnected way.

While Piaget, Vygotsky, and Bruner have different perspectives on how learning occurs, they all emphasize the active role of the learner in constructing knowledge and the importance of social interaction and cultural influences in the learning process.

According to the given data the length of a \(90^{0}\) arc is \(\pi /2\) or approximately \(1.57\) feet.

In geometry, the length of an arc is the distance along the curved line that makes up the arc. It is a measure of the "length" of a portion of a circle's circumference, and it is usually expressed in the same units as the circle's radius.

According to the given information:

The length of a \(90^{0}\) arc in a circle with radius \(1\) foot can be calculated using the formula:

Length of arc = (angle/\(360\)) x \(2\pi r\)

where angle is the central angle of the arc in degrees, r is the radius of the circle, and \(\pi\) is a mathematical constant approximately equal to \(3.14159\).

Substituting the given values, we have:

Length of arc = (\(90/360\)) x \(2\pi(1 ft)\)

Length of arc = \((1/4)\) x \(2\pi ft\)

Length of arc = \(\pi /2 ft\)

Therefore, the length of the \(90^{0}\) arc is \(\pi /2 feet\) or approximately \(1.57 feet\)

the length of the 90° arc is π/4 feet or approximately 0.785 feet

What is arc of circle?

In geometry, an arc of a circle is a portion of the circle's circumference. It is defined by two endpoints and all points along the circle between those endpoints. The measure of an arc is typically given in degrees or radians and can be used to calculate various properties of the circle, such as its length, area, and sector angles.

The formula for the length of an arc is:

L = (θ/360) × 2πr

where L is the length of the arc, θ is the central angle of the arc in degrees, and r is the radius of the circle.

In this case, θ = 90° and r = 1 ft, so we have:

L = (90/360) × 2π(1) = (1/4) × π = π/4

Therefore, the length of the 90° arc is π/4 feet or approximately 0.785 feet (rounded to 3 decimal places).

The correct answer is c) There is only one number in the data set. the fact that the mean of the data set is 3 and the MAD is 0 tells us that there is only one number in the data set, and that number is 3.

What is mean?

In statistics, the mean (also known as the arithmetic mean or average) is a measure of central tendency that represents the sum of a set of numbers divided by the total number of numbers in the set.

The mean is a measure of central tendency that gives an idea of the typical value in a data set. It is calculated by adding up all the values in the data set and then dividing by the number of values.

If the mean of a data set is 3, it means that the sum of all the values in the data set divided by the number of values is equal to 3. So, if we denote the data set as {x1, x2, x3, ..., xn}, we have:

(x1 + x2 + x3 + ... + xn) / n = 3

If the MAD of a data set is 0, it means that the absolute differences between each value and the mean are all 0, which is only possible when all the values in the data set are the same. In other words, if we denote the data set as {x1, x2, x3, ..., xn}, we have:

| x1 - 3 | + | x2 - 3 | + | x3 - 3 | + ... + | xn - 3 | / n = 0

This can only be true if all the values in the data set are equal to 3, so the data set is {3}.

Therefore, the fact that the mean of the data set is 3 and the MAD is 0 tells us that there is only one number in the data set, and that number is 3.
