According to Mrs. Wendell 's histogram (shown below), 25% of her cows weigh between 800 and 1199 pounds.

A popular charting tool is a histogram. On an interval scale, it is used to describe either discrete or continuous data. It is widely used to show the key properties of distribution of the data in an easy-to-understand fashion.

Examine the histogram to see if it shows a normal distribution. Once you've plotted all of the frequencies here on the histogram, it will take on a shape. If the shape resembles a bell curve, it indicates that perhaps the frequencies are evenly distributed. A peak would appear on the histogram.

Ms. Wendell sells 25% of her her cows. While purchasing a cow, it is important to remember that weight is an important factor. While there may be some exceptions, the majority of cows sold in the United States weigh between 800 and 1200 pounds.

So, if your farm falls within this range, it would be wise to consider buying a cow from Mrs. Wendell .

Additionally, based on these numbers alone, it would make sense for you to purchase one or more cattle from Mrs. Wendell.

Therefore,

according to Mrs. Wendell 's histogram (shown below), 25% of her cows weigh between 800 and 1199 pounds.

Ms Patel purchased 38 shares of stock a and 41 shares of stock b

Total amount invested in the two stocks = $825

Value of stock a = $12.41

Value of stock b = $8.62

Let the number of shares of stock a be x

Let the number of shares of stock b be y

Therefore, forming the equation we get:

x + y = 79------(1)

12.41x + 8.62y = 825

1241x + 862y = 82500 ------(2)

Multiplying equation (1) by 862 we get,

862x + 862y = 68098------(3)

Equating equations (2) and (3) we get

379x = 14402

x = 38

Putting x = 38 in (1) we get

y = 41

Hence, she purchased 38 shares of stock a and 41 shares of stock b

The probability, P (yellow), that a yellow chip is drawn from the bag is 4/19.

Probability is a term used in mathematics to determine the likelihood that an incident will take place as in this case is the likelihood that a yellow chip is drawn from the bag.

Probability can be given by the formula:

probability= Number of favorable outcomes ÷ Total number of possible outcomes

Hence, in this problem, the formula for probability will be:

P (yellow) = Number of yellow chips / Total number of chips in the bag

The total number of chips in the bag will be equal to the sum of the chips of all colors.

That is, total number of chips = 3 blue chips + 7 red chips + 4 yellow chips + 5 green chips

Total number of chips = 19 chips

So the probability of a yellow chip being drawn out will be:

P ( yellow) = 4/19

Step-by-step explanation:

The box with rhombus and rectangle are the two shapes that each have opposite sides of equal length.

In the options given, the first box has a rhombus and a rectangle.

We know that a rhombus has all four sides of equal length.

This means that opposite sides are of equal length.

We also know that a rectangle has opposite sides of equal length.

In this option, both of them have opposite sides of equal length.

So, this is the correct answer.

The second box has a quadrilateral and a trapezoid.

The trapezoid is a quadrilateral with one pair of opposite sides parallel, but the length of the sides is not equal. A trapezoid might have right angles, then it is called a right trapezoid.

A quadrilateral is a two-dimensional shape that has 4 sides.

In this option, both shapes do not have opposite sides of equal length. So, this is not the right answer to the given question.

The third box has a trapezoid and a parallelogram.

A trapezoid is a quadrilateral with one pair of opposite sides parallel, but the length of the sides is not equal. A trapezoid might have right angles, then it is called a right trapezoid.

Answer:

Length is 11 meters

Step-by-step explanation:

Formula we use,

→ P = 2(l + w)

Then the length of rectangle will be,

→ 32 = 2(L + 5)

→ 2L + 10 = 32

→ 2L = 32 - 10

→ L = 22/2

→ [ L = 11 m ]

Hence, the length is 11 meters.

Positive Numbers definition the meaning of positive whole numbers in numerical states that "Numbers that are more noteworthy than zero are positive numbers". Numbers can be grouped into three kinds: negative whole numbers, zero, and positive whole numbers. Normal numbers are extremely normal to people since they come from counting objects like apples or sheep.

If s is integer

S = n (a + l)/2

Normal numbers can be utilized to assess your assets, the amount of you possess. There is no biggest regular number. The following regular number can be found by adding 1 to the ongoing normal number, creating numbers that go on "for eternity".

1 inch of the board is left

For the given wire, the length of each piece of wire will be 76inch and 24 inch and quadratic equation will be x² - 100x + 1800 = 0

An algebraic equation of a second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.

Given,

Length of wire = 100 inches

Sum of the areas of two squares = 400 inch²

let length of one wire - x

the length of other wire will be - 100-x

Now, the area of the square = Side²

⇒ (x/4)² + ((100 - x)/4)² = 400

⇒ (1/4)²  (x² + 10000 + x² - 2(100)(x)) = 400

⇒ 10000 + 2x² + - 200x = 400 × 16

⇒ 2x² - 200x = 6400 - 10000

⇒ 2x² - 200x = - 3600

⇒ x² - 100x + 1800 = 0

⇒On solving for the value of x, we have x= 76 and 24

Now,

76/4 = 19,

24/4 = 6

So, we have the length of each wire as 76inch and 24inch

Based on the information illustrated,

If every component of a set X is related to one another, then a relation R over that set is said to be reflexive.

If (a, a) R for all  A, that is, if every element of A is R-related to itself, or if aRa for every a A, then R is set to be reflexive.

In the example question, S is the set of all Park students, and R is a relation over S.

When a relationship is described as xRy, it signifies that x and y have the same biological mother.

This relation is obviously a reflexive relation. xRx means x and x has the same biological mother. In this case, the relation satisfies the requirement for all aR (a,a) R.

The required percentage of US states having their names starting with W is 8 %. This is gained by using the concept of percentage.

What do you mean by percentage?

The percentage is usually denoted by the symbol '%'. It is defined as the quantity or ratio which is being expressed in a fraction of 100, where 100 is the denominator.

Calculation of the percentage of US states having their names starting with W

Given:

Total states in US = 50

US states that start with the letter W = 4

Fraction in favour of the names of states starting with the letter W is given by = 4 / 50

Therefore the percentage of US states having their names starting with the letter W is equal to the fraction in favour * 100 %

= 4 / 50 * 100 %

= 4 * 2 %

= 8 %

Hence, the percentage of US states having their first letter as W is 8 %.

The translations for this problem are given, respectively, by:

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

For the first translation, the orientation remains the same, just the positions changes, hence it is translated 9 units to the right and 2 units down.

For the second translation, the rule applied to each vertex was:

(x,y) -> (x,-y).

Hence it was reflected across the x-axis.
