The result of the normal probability distribution being bell-shaped is that the mean, median, and mode are at the center.

This means that the center of the bell-shaped curve represents the most likely occurrence of the data and that the values are symmetrically distributed around the mean.

The mean, median, and mode of a normal distribution are equal, which means that they are all located at the center of the bell-shaped curve. This is an important characteristic of the normal distribution and sets it apart from other distributions where the mean, median, and mode may not be equal.

In a normal distribution, the area on each side of the mean does not equal 1.00, but rather approaches 1.00 as the curve becomes more symmetrical. The height of the curve at the mean represents the highest probability of occurrence, and the probabilities decrease as the values deviate from the mean.

The inequality that describes a pizza with an area larger than a mall pizza (with an area of 730730730 square centimeters) can be written as:

p > 730730730

The inequality "p > 730730730" is a mathematical expression that compares the area of a pizza (represented by the variable "p") to the area of a mall pizza (730730730 square centimeters).

The inequality uses the greater than symbol ">" to indicate that the area of the pizza represented by "p" must be greater than the area of the mall pizza.

"p" represents the area of the larger pizza in square centimeters. The inequality states that the area of the larger pizza (p) must be greater than the area of the mall pizza (730730730 square centimeters).

This inequality can be useful in situations where we want to compare the size of two pizzas and determine which is larger. By evaluating whether the area of a pizza (represented by "p") satisfies the inequality, we can determine whether it is larger or smaller than the mall pizza (with an area of (730730730 square centimeters).

Cost = 20 + 1x = 20 + x

Step-by-step explanation:

Membership fee is $20 per month. This amount has to be paid whether he buys pizzas or not that month

Kyle spending on this shirt at end up is, $63.07.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

Kyle is looking to buy a shirt that normally costs $85.

Here, Lucky for Kyle, the store selling the shirt is having a 30% off sale for all items.

Hence, The discount price is,

⇒ 30% of 85

⇒ 30/100 × 85

⇒ $25.5

So, The price of shirt after discount = $85 - %25.5

                                                       = $59.5

Since, After the discount, Kyle must pay 6% sales tax on the shirt.

Hence, The sales tax is,

⇒ 6% of 59.5

⇒ 6/100 × 59.5

⇒ $3.57

Thus, The amount to pay at endup by Kyle = $59.5 + $3.57

                                                                  = $63.07

The required probability for the number of phone calls more than two in next 30 minutes is equal to ( 18 / 5)e⁻⁶.

Number of phone calls between 6pm and 8.00 pm 'n' = About 6 calls

Using Poisson's distribution we have,

P ( X = x ) = ( e⁻ⁿ nˣ ) / x!

Probability of receiving more than 2 phone calls in next 30 minutes

= P( X > 2 )

= P ( X = 3 ) + P ( X = 4 ) + P ( X = 5) + P( X = 6)

= ( e⁻⁶ 6³ ) / 3! +  ( e⁻⁶ 6⁴ ) / 4! +  ( e⁻⁶ 6⁵) / 5! +  ( e⁻⁶ 6⁶ ) / 6!

=  ( e⁻⁶ 6³ ) / 3! [ 1 +  (6 / 4) + (6² / 5× 4 ) + ( 6³ / 6 ×5× 4) ]

= ( e⁻⁶ 6³ ) / 3! [ ( 20 + 30 + 72 ) / 20 ]

According to the problem,The area of the figure is approximately 34 square units.

A square is a four-sided plane figure where all sides are equal length and all angles are right angles. It is a two-dimensional shape with four equal-length sides and four equal angles of 90°. Squares are often used in designs and architecture, and are an important part of Euclidean geometry. They are also found in nature, such as in a honeycomb, in a checkerboard pattern, and in tessellations.

To calculate this, we need to calculate the area of the square and the area of the circle's segment. The side of the square is 4 units, so the area of the square is 4 x 4 = 16 square units. The radius of the circle is also 4 units, so the area of the circle's segment is (1/2)πr^2, which is (1/2)π(4^2) = 16π/2 = 16 x 3.14/2 = 24.96 square units.

Therefore, the area of the figure is 16 + 24.96 = 40.96 square units, which is approximately 34 square units to the nearest whole number.

The increase in the area of the circle is 64π, not 39π. If the original circle had an area of 25m, then the original radius was 5. The new radius would be 5 + 3 = 8. The new area would be 8^2 * pi = 64 * pi = 64π.

Let X be the number of 4 point scores that Hunter made and Y be the number of 9 point scores. X + Y = total number of scores and 4X + 9Y = 755. Substituting Y = 100 + X, we get 4X + 900 = 755. Solving for X, we get X = 41. Therefore, Hunter made 41 4 point scores.

The equation be |2x-3| = 7 then the set of values is the solution set be (2, -5).

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. When two expressions are joined by an equal sign, a mathematical statement is called an equation.

In mathematics, to solve an equation is to identify its solutions, which are the values (numbers, functions, sets, etc.) that satisfy the requirement expressed by the equation. An equation typically consists of two expressions connected by an equals sign. A variable or variables are labeled as unknowns when looking for a solution.

Any combination of a number, a variable, and operation symbols is considered an expression. Two expressions are combined to form an equation, which is joined by the equal sign.

Let the equation be |2x-3| = 7

We know that if [tex]$|a|=b, a=\pm b$[/tex].

Since we do not know if 2x - 3 exists positive or negative, we will need a [tex]$\pm$[/tex] on the 7 :

[tex]$|2 x-3|=7 \Rightarrow 2 x-3=\pm 7$$[/tex]

Add 3 to both sides, and finally divide by 2, we get

[tex]$$\begin{aligned}& 2 x=3 \pm 7 \\& x=\frac{3}{2} \pm \frac{7}{2}\end{aligned}$$[/tex]

So x exists equal to either 10/2 = 5 or -4/2 = -2.

The distance between two raisins will increase by a factor of the square root of 2.

As the bread dough rises and doubles in size, each linear dimension of the dough, including the distance between the raisins, will also double. This means that the distance between two raisins will increase by a factor of 2.

However, since the change in distance is related to a change in the linear dimension, and not the area, the increase in distance is proportional to the square root of 2, not 2. This means that the distance between the two raisins will increase by a factor of the square root of 2, or approximately 1.41.

This increase in distance between the raisins is a result of the increase in the volume of the dough, as the yeast ferments the sugars in the dough, producing carbon dioxide and causing the dough to rise. The increase in volume causes the dough to stretch, resulting in the increased distance between the raisins.
